files. Since key/data pairs are cached in memory, failing to -sync the file with the DB->close or <a href="../api_c/db_sync.html">DB->sync</a> function may result -in inconsistent or lost information. -<p>The <b>flags</b> parameter must be set to 0 or the following value: -<p><dl compact> -<p><dt><a name="DB_NOSYNC">DB_NOSYNC</a><dd>Do not flush cached information to disk. -<p>The <a href="../api_c/db_close.html#DB_NOSYNC">DB_NOSYNC</a> flag is a dangerous option.

The <b>database</b> argument is -optional and allows applications to have multiple logical databases in a -single physical file. While no <b>database</b> argument needs to be -specified, it is an error to attempt to open a second database in a -<b>file</b> that was not initially created using a <b>database</b> name. -In-memory databases never intended to be preserved on disk may -be created by setting both the <b>file</b> and <b>database</b> arguments -to NULL.

For example, the deletion of record number 4 causes records -numbered 5 and greater to be renumbered downward by 1. If a cursor was -positioned to record number 4 before the deletion, it will reference the -new record number 4, if any such record exists, after the deletion.

If a cursor was positioned to record -number 8 or greater before the insertion, it will be shifted upward 1 -logical record, continuing to reference the same record as it did before. -<p>For these reasons, concurrent access to a Recno database with the -<b>-renumber</b> flag specified may be largely meaningless, although it -is supported. -<p><dt>-snapshot<dd>This argument specifies that any specified <b>-source</b> file be read -in its entirety when the database is opened. If this argument is not -specified, the <b>-source</b> file may be read lazily. -<p><dt>-source file<dd>Set the underlying source file for the Recno access method. The purpose -of the <b>-source</b> file is to provide fast access and modification -to databases that are normally stored as flat text files. -<p>If the <b>-source</b> argument is give, it specifies an underlying flat -text database file that is read to initialize a transient record number -index. In the case of variable length records, the records are separated -as specified by <b>-delim</b>. For example, standard UNIX byte stream -files can be interpreted as a sequence of variable length records -separated by <newline> characters. -<p>In addition, when cached data would normally be written back to the -underlying database file (e.g., the <i>db</i> <b>close</b> or <i>db</i> <b>sync</b> -commands are called), the in-memory copy of the database will be written -back to the <b>-source</b> file. -<p>By default, the backing source file is read lazily, i.e., records are not -read from the file until they are requested by the application. -<b>If multiple processes (not threads) are accessing a Recno database -concurrently and either inserting or deleting records, the backing source -file must be read in its entirety before more than a single process -accesses the database, and only that process should specify the backing -source argument as part of the <b>berkdb open</b> call. See the <b>-snapshot</b> -argument for more information.</b> -<p><b>Reading and writing the backing source file specified by <b>-source</b> -cannot be transactionally protected because it involves filesystem -operations that are not part of the Berkeley DB transaction methodology.</b> -For this reason, if a temporary database is used to hold the records, -i.e., no <b>file</b> argument was specified to the <b>berkdb open</b> call, -it is possible to lose the contents of the <b>-file</b> file, e.g., if -the system crashes at the right instant. If a file is used to hold the -database, i.e., a file name was specified as the <b>file</b> argument -to <b>berkdb open</b>, normal database recovery on that file can be used to -prevent information loss, although it is still possible that the contents -of <b>-source</b> will be lost if the system crashes. -<p>The <b>-source</b> file must already exist (but may be zero-length) when -<b>berkdb open</b> is called. -<p>It is not an error to specify a read-only <b>-source</b> file when -creating a database, nor is it an error to modify the resulting database. -However, any attempt to write the changes to the backing source file using -either the <i>db</i> <b>close</b> or <i>db</i> <b>sync</b> commands will fail, of course. -Specify the <b>-nosync</b> argument to the <i>db</i> <b>close</b> command will -stop it from attempting to write the changes to the backing file, instead, -they will be silently discarded. -<p>For all of the above reasons, the <b>-source</b> file is generally used -to specify databases that are read-only for Berkeley DB applications, and that -are either generated on the fly by software tools, or modified using a -different mechanism, e.g., a text editor. -<p><dt>-truncate<dd>Physically truncate the underlying file, discarding all previous databases -it might have held.

Applications whose data -could be stored in more than one access method may want to benchmark their -performance using the different candidates. -<p>One of the strengths of Berkeley DB is that it provides multiple access methods -with almost identical interfaces to the different access methods. This -means that it is simple to modify an application to use a different access -method. Applications can easily benchmark the different Berkeley DB access -methods against each other for their particular data set and access pattern. -<p>Most applications choose between using the Btree or Hash access methods -or between using the Queue and Recno access methods, because each of the -two pairs offer similar functionality. -<h3>Hash or Btree?</h3> -<p>The Hash and Btree access methods should be used when logical record -numbers are not the primary key used for data access. (If logical record -numbers are a secondary key used for data access, the Btree access method -is a possible choice, as it supports simultaneous access by a key and a -record number.) -<p>Keys in Btrees are stored in sorted order and the relationship between -them is defined by that sort order. For this reason, the Btree access -method should be used when there is any locality of reference among keys. -Locality of reference means that accessing one particular key in the -Btree implies that the application is more likely to access keys near to -the key being accessed, where "near" is defined by the sort order. For -example, if keys are timestamps, and it is likely that a request for an -8AM timestamp will be followed by a request for a 9AM timestamp, the -Btree access method is generally the right choice. Or, for example, if -the keys are names, and the application will want to review all entries -with the same last name, the Btree access method is again a good choice. -<p>There is little difference in performance between the Hash and Btree -access methods on small data sets, where all, or most of, the data set -fits into the cache. However, when a data set is large enough that -significant numbers of data pages no longer fit into the cache, then the -Btree locality of reference described above becomes important for -performance reasons. For example, there is no locality of reference for -the Hash access method, and so key "AAAAA" is as likely to be stored on -the same data page with key "ZZZZZ" as with key "AAAAB". In the Btree -access method, because items are sorted, key "AAAAA" is far more likely -to be near key "AAAAB" than key "ZZZZZ". So, if the application exhibits -locality of reference in its data requests, then the Btree page read into -the cache to satisfy a request for key "AAAAA" is much more likely to be -useful to satisfy subsequent requests from the application than the Hash -page read into the cache to satisfy the same request. This means that -for applications with locality of reference, the cache is generally much -"hotter" for the Btree access method than the Hash access method, and -the Btree access method will make many fewer I/O calls. -<p>However, when a data set becomes even larger, the Hash access method can -outperform the Btree access method. The reason for this is that Btrees -contain more metadata pages than Hash databases. The data set can grow -so large that metadata pages begin to dominate the cache for the Btree -access method. If this happens, the Btree can be forced to do an I/O -for each data request because the probability that any particular data -page is already in the cache becomes quite small. Because the Hash access -method has fewer metadata pages, its cache stays "hotter" longer in the -presence of large data sets. In addition, once the data set is so large -that both the Btree and Hash access methods are almost certainly doing -an I/O for each random data request, the fact that Hash does not have to -walk several internal pages as part of a key search becomes a performance -advantage for the Hash access method as well. -<p>Application data access patterns strongly affect all of these behaviors, -for example, accessing the data by walking a cursor through the database -will greatly mitigate the large data set behavior describe above because -each I/O into the cache will satisfy a fairly large number of subsequent -data requests. -<p>In the absence of information on application data and data access -patterns, for small data sets either the Btree or Hash access methods -will suffice. For data sets larger than the cache, we normally recommend -using the Btree access method. If you have truly large data, then the -Hash access method may be a better choice. The <a href="../../utility/db_stat.html">db_stat</a> utility -is a useful tool for monitoring how well your cache is performing. -<h3>Queue or Recno?</h3> -<p>The Queue or Recno access methods should be used when logical record -numbers are the primary key used for data access. The advantage of the -Queue access method is that it performs record level locking and for this -reason supports significantly higher levels of concurrency than the Recno -access method. The advantage of the Recno access method is that it -supports a number of additional features beyond those supported by the -Queue access method, such as variable-length records and support for -backing flat-text files. -<p>Logical record numbers can be mutable or fixed: mutable, where logical -record numbers can change as records are deleted or inserted, and fixed, -where record numbers never change regardless of the database operation. -It is possible to store and retrieve records based on logical record -numbers in the Btree access method.

The standard library interface is ANSI C.

For example, you might have a local server written in C or C++, a -script for an administrator written in Perl or Tcl, and a web based user -interface written in Java, all sharing a single database environment. -<h3>C</h3> -<p>The Berkeley DB library is written entirely in ANSI C. C applications use a -single include file: -<p><blockquote><pre>#include <db.h></pre></blockquote> -<h3>C++</h3> -<p>The C++ classes provide a thin wrapper around the C API, with the major -advantages being improved encapsulation and an optional exception -mechanism for errors. C++ applications use a single include file: -<p><blockquote><pre>#include <db_cxx.h></pre></blockquote> -<p>The classes and methods are named in a fashion that directly corresponds -to structures and functions in the C interface. Likewise, arguments to -methods appear in the same order as the C interface, except to remove the -explicit <b>this</b> pointer. The #defines used for flags are identical -between the C and C++ interfaces. -<p>As a rule, each C++ object has exactly one structure from the underlying -C API associated with it. The C structure is allocated with each -constructor call and deallocated with each destructor call. Thus, the -rules the user needs to follow in allocating and deallocating structures -are the same between the C and C++ interfaces. -<p>To ensure portability to many platforms, both new and old, Berkeley DB makes as -few assumptions as possible about the C++ compiler and library. For -example, it does not expect STL, templates or namespaces to be available. -The newest C++ feature used is exceptions, which are used liberally to -transmit error information. Even the use of exceptions can be disabled -at runtime. -<h3>JAVA</h3> -<p>The Java classes provide a layer around the C API that is almost identical -to the C++ layer. The classes and methods are, for the most part -identical to the C++ layer. Db constants and #defines are represented as -"static final int" values. Error conditions are communicated as Java -exceptions. -<p>As in C++, each Java object has exactly one structure from the underlying -C API associated with it. The Java structure is allocated with each -constructor or open call, but is deallocated only by the Java garbage -collector. Because the timing of garbage collection is not predictable, -applications should take care to do a close when finished with any object -that has a close method. -<h3>Dbm/Ndbm, Hsearch</h3> -<p>Berkeley DB supports the standard UNIX interfaces <a href="../../api_c/dbm.html">dbm</a> (or its -<a href="../../api_c/dbm.html">ndbm</a> variant) and <a href="../../api_c/hsearch.html">hsearch</a>.

This form of logging can add significant bulk -to your log, but can permit debugging application errors that are almost -impossible to find any other way. To turn on these log messages, specify -the --enable-debug_rop and --enable-debug_wop configuration options when -configuring Berkeley DB. See <a href="../../ref/build_unix/conf.html">Configuring -Berkeley DB</a> for more information. -<h3>Extracting Committed Transactions and Transaction Status</h3> -<p>Sometimes it is useful to use the human-readable log output to determine -which transactions committed and aborted. The awk script, commit.awk, -found in the db_printlog directory of the Berkeley DB distribution allows you -to do just that. The command: -<p><blockquote><pre>awk -f commit.awk log_output</pre></blockquote> -where log_output is the output of db_printlog will display a list of -the transaction IDs of all committed transactions found in the log. -<p>If you need a complete list of both committed and aborted transactions, -then the script status.awk will produce that. The syntax is: -<p><blockquote><pre>awk -f status.awk log_output</pre></blockquote> -<h3>Extracting Transaction Histories</h3> -<p>Another useful debugging aid is to print out the complete history of a -transaction. The awk script txn.awk, allows you to do that. The -command line: -<p><blockquote><pre>awk -f txn.awk TXN=txnlist log_output</pre></blockquote> -where log_output is the output of <a href="../../utility/db_printlog.html">db_printlog</a> and txnlist is -a comma-separated list of transaction IDs, will display all log records -associated with the designated transaction ids. -<h3>Extracting File Histories</h3> -<p>The awk script fileid.awk, allows you to extract all log records that -affect particular files. The syntax for the fileid.awk script is: -<p><blockquote><pre>awk -f fileid.awk PGNO=fids log_output</pre></blockquote> -<p>where log_output is the output of db_printlog and fids is a -comma-separated list of fileids. The script will output all log -records that reference the designated file. -<h3>Extracting Page Histories</h3> -<p>The awk script pgno.awk, allows you to extract all log records that -affect particular pages. As currently designed, however, it will -extract records of all files with the designated page number, so this -script is most useful in conjunction with the fileid script. The syntax -for the pgno.awk script is: -<p><blockquote><pre>awk -f pgno.awk PGNO=pgnolist log_output</pre></blockquote> -<p>where log_output is the output of db_printlog and pgnolist is a -comma-separated list of page numbers. The script will output all log -records that reference the designated page numbers. -<h3>Other log processing tools</h3> -<p>The awk script count.awk will print out the number of log records -encountered that belonged to some transaction (that is the number of log -records excluding those for checkpoints and non-transaction protected -operations). -<p>The script range.awk will extract a subset of a log. This is useful -when the output of <a href="../../utility/db_printlog.html">db_printlog</a> is too large to be reasonably -manipulated with an editor or other tool. -<p>The syntax for range.awk is: -<p><blockquote><pre>awk -f range.awk START_FILE=sf START_OFFSET=so END_FILE=ef END_OFFSET=eo log_output</pre></blockquote> -<p>where the <b>sf</b> and <b>so</b> represent the log sequence number -(LSN) of the beginning of the sublog you wish to extract and <b>ef</b> -and <b>eo</b> represent the LSN of the end of the sublog you wish to -extract. -<table><tr><td><br></td><td width="1%"><a href="../../ref/debug/runtime.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../../ref/toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../../ref/debug/common.html"><img src="../../images/next.gif" alt="Next"></a> -</td></tr></table> -<p><font size=1><a href="http://www.sleepycat.com">Copyright Sleepycat Software</a></font> -</body> -</html> diff --git a/bdb/docs/ref/debug/runtime.html b/bdb/docs/ref/debug/runtime.html deleted file mode 100644 index 40fec7e82dd..00000000000 --- a/bdb/docs/ref/debug/runtime.html +++ /dev/null @@ -1,47 +0,0 @@ -<!--$Id: runtime.so,v 10.16 2000/12/01 20:15:25 bostic Exp $--> -<!--Copyright 1997, 1998, 1999, 2000 by Sleepycat Software, Inc.--> -<!--All rights reserved.--> -<html> -<head> -<title>Berkeley DB Reference Guide: Run-time error information</title> -<meta name="description" content="Berkeley DB: An embedded database programmatic toolkit."> -<meta name="keywords" content="embedded,database,programmatic,toolkit,b+tree,btree,hash,hashing,transaction,transactions,locking,logging,access method,access methods,java,C,C++"> -</head> -<body bgcolor=white> -<table><tr valign=top> -<td><h3><dl><dt>Berkeley DB Reference Guide:<dd>Debugging</dl></h3></td> -<td width="1%"><a href="../../ref/debug/compile.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../../ref/toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../../ref/debug/printlog.html"><img src="../../images/next.gif" alt="Next"></a> -</td></tr></table> -<p> -<h1 align=center>Run-time error information</h1> -<p>Normally, when an error occurs in the Berkeley DB library, an integer value -(either a Berkeley DB specific value, or a system <b>errno</b> value) is -returned by the function.

It's time -now to consider Berkeley DB in particular and see how it fits into the -framework we have introduced. The key question is, what kinds of -applications should use Berkeley DB? -<p>Berkeley DB is an open source embedded database library that provides -scalable, high-performance, transaction-protected data management -services to applications. Berkeley DB provides a simple function-call API -for data access and management. -<p>By "open source," we mean that Berkeley DB is distributed under a license that -conforms to the <a href="http://www.opensource.org/osd.html">Open -Source Definition</a>. This license guarantees that Berkeley DB is freely -available for use and redistribution in other open source products. -<a href="http://www.sleepycat.com">Sleepycat Software</a> sells -commercial licenses for redistribution in proprietary applications, but -in all cases the complete source code for Berkeley DB is freely available for -download and use. -<p>Berkeley DB is embedded because it links directly into the application. It -runs in the same address space as the application. As a result, no -inter-process communication, either over the network or between -processes on the same machine, is required for database operations. -Berkeley DB provides a simple function-call API for a number of programming -languages, including C, C++, Java, Perl, Tcl, Python, and PHP. All -database operations happen inside the library. Multiple processes, or -multiple threads in a single process, can all use the database at the -same time as each uses the Berkeley DB library. Low-level services like -locking, transaction logging, shared buffer management, memory -management, and so on are all handled transparently by the library. -<p>The library is extremely portable. It runs under almost all UNIX and -Linux variants, Windows, and a number of embedded real-time operating -systems. It runs on both 32-bit and 64-bit systems. -It has been deployed on high-end -Internet servers, desktop machines, and on palmtop computers, set-top -boxes, in network switches, and elsewhere. Once Berkeley DB is linked into -the application, the end user generally does not know that there's a -database present at all. -<p>Berkeley DB is scalable in a number of respects. The database library itself -is quite compact (under 300 kilobytes of text space on common -architectures), but it can manage databases up to 256 terabytes in size. -It also supports high concurrency, with thousands of users operating on -the same database at the same time. Berkeley DB is small enough to run in -tightly constrained embedded systems, but can take advantage of -gigabytes of memory and terabytes of disk on high-end server machines. -<p>Berkeley DB generally outperforms relational and object-oriented database -systems in embedded applications for a couple of reasons. First, because -the library runs in the same address space, no inter-process -communication is required for database operations. The cost of -communicating between processes on a single machine, or among machines -on a network, is much higher than the cost of making a function call. -Second, because Berkeley DB uses a simple function-call interface for all -operations, there is no query language to parse, and no execution plan -to produce. -<h3>Data Access Services</h3> -<p>Berkeley DB applications can choose the storage structure that best suits the -application. Berkeley DB supports hash tables, B-trees, simple -record-number-based storage, and persistent queues. Programmers can -create tables using any of these storage structures, and can mix -operations on different kinds of tables in a single application. -<p>Hash tables are generally good for very large databases that need -predictable search and update times for random-access records. Hash -tables allow users to ask, "Does this key exist?" or to fetch a record -with a known key. Hash tables do not allow users to ask for records -with keys that are close to a known key. -<p>B-trees are better for range-based searches, as when the application -needs to find all records with keys between some starting and ending -value. B-trees also do a better job of exploiting <i>locality -of reference</i>. If the application is likely to touch keys near each -other at the same time, the B-trees work well. The tree structure keeps -keys that are close together near one another in storage, so fetching -nearby values usually doesn't require a disk access. -<p>Record-number-based storage is natural for applications that need -to store and fetch records, but that do not have a simple way to -generate keys of their own. In a record number table, the record -number is the key for the record. Berkeley DB will can generate these -record numbers automatically. -<p>Queues are well-suited for applications that create records, and then -must deal with those records in creation order. A good example is -on-line purchasing systems. Orders can enter the system at any time, -but should generally be filled in the order in which they were placed. -<h3>Data management services</h3> -<p>Berkeley DB offers important data management services, including concurrency, -transactions, and recovery. All of these services work on all of the -storage structures. -<p>Many users can work on the same database concurrently. Berkeley DB handles -locking transparently, ensuring that two users working on the same -record do not interfere with one another. -<p>The library provides strict ACID transaction semantics. Some systems -allow the user to relax, for example, the isolation guarantees that the -database system makes. Berkeley DB ensures that all applications can see only -committed updates. -<p>Multiple operations can be grouped into a single transaction, and can -be committed or rolled back atomically. Berkeley DB uses a technique called -<i>two-phase locking</i> to be sure that concurrent transactions -are isolated from one another, and a technique called -<i>write-ahead logging</i> to guarantee that committed changes -survive application, system, or hardware failures. -<p>When an application starts up, it can ask Berkeley DB to run recovery. -Recovery restores the database to a clean state, with all committed -changes present, even after a crash. The database is guaranteed to be -consistent and all committed changes are guaranteed to be present when -recovery completes. -<p>An application can specify, when it starts up, which data management -services it will use. Some applications need fast, -single-user, non-transactional B-tree data storage. In that case, the -application can disable the locking and transaction systems, and will -not incur the overhead of locking or logging. If an application needs -to support multiple concurrent users, but doesn't need transactions, it -can turn on locking without transactions. Applications that need -concurrent, transaction-protected database access can enable all of the -subsystems. -<p>In all these cases, the application uses the same function-call API to -fetch and update records. -<h3>Design</h3> -<p>Berkeley DB was designed to provide industrial-strength database services to -application developers, without requiring them to become database -experts. It is a classic C-library style <i>toolkit</i>, providing -a broad base of functionality to application writers. Berkeley DB was designed -by programmers, for programmers: its modular design surfaces simple, -orthogonal interfaces to core services, and it provides mechanism (for -example, good thread support) without imposing policy (for example, the -use of threads is not required). Just as importantly, Berkeley DB allows -developers to balance performance against the need for crash recovery -and concurrent use. An application can use the storage structure that -provides the fastest access to its data and can request only the degree -of logging and locking that it needs. -<p>Because of the tool-based approach and separate interfaces for each -Berkeley DB subsystem, you can support a complete transaction environment for -other system operations. Berkeley DB even allows you to wrap transactions -around the standard UNIX file read and write operations! Further, Berkeley DB -was designed to interact correctly with the native system's toolset, a -feature no other database package offers. For example, Berkeley DB supports -hot backups (database backups while the database is in use), using -standard UNIX system utilities, e.g., dump, tar, cpio, pax or even cp. -<p>Finally, because scripting language interfaces are available for Berkeley DB -(notably Tcl and Perl), application writers can build incredibly powerful -database engines with little effort. You can build transaction-protected -database applications using your favorite scripting languages, an -increasingly important feature in a world using CGI scripts to deliver -HTML. -<table><tr><td><br></td><td width="1%"><a href="../../ref/intro/terrain.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../../ref/toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../../ref/intro/dbisnot.html"><img src="../../images/next.gif" alt="Next"></a> -</td></tr></table> -<p><font size=1><a href="http://www.sleepycat.com">Copyright Sleepycat Software</a></font> -</body> -</html> diff --git a/bdb/docs/ref/intro/dbisnot.html b/bdb/docs/ref/intro/dbisnot.html deleted file mode 100644 index a55fa71763e..00000000000 --- a/bdb/docs/ref/intro/dbisnot.html +++ /dev/null @@ -1,146 +0,0 @@ -<!--$Id: dbisnot.so,v 10.3 2000/12/14 20:52:03 bostic Exp $--> -<!--Copyright 1997, 1998, 1999, 2000 by Sleepycat Software, Inc.--> -<!--All rights reserved.--> -<html> -<head> -<title>Berkeley DB Reference Guide: What is Berkeley DB not?</title> -<meta name="description" content="Berkeley DB: An embedded database programmatic toolkit."> -<meta name="keywords" content="embedded,database,programmatic,toolkit,b+tree,btree,hash,hashing,transaction,transactions,locking,logging,access method,access methods,java,C,C++"> -</head> -<body bgcolor=white> -<table><tr valign=top> -<td><h3><dl><dt>Berkeley DB Reference Guide:<dd>Introduction</dl></h3></td> -<td width="1%"><a href="../../ref/intro/dbis.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../../ref/toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../../ref/intro/need.html"><img src="../../images/next.gif" alt="Next"></a> -</td></tr></table> -<p> -<h1 align=center>What is Berkeley DB not?</h1> -<p>In contrast to most other database systems, Berkeley DB provides relatively -simple data access services. -<p>Records in Berkeley DB are (<i>key</i>, <i>value</i>) pairs. Berkeley DB -supports only a few logical operations on records. They are: -<ul type=disc> -<li>Insert a record in a table. -<li>Delete a record from a table. -<li>Find a record in a table by looking up its key. -<li>Update a record that has already been found. -</ul> -<p>Notice that Berkeley DB never operates on the value part of a record. -Values are simply payload, to be -stored with keys and reliably delivered back to the application on -demand. -<p>Both keys and values can be arbitrary bit strings, either fixed-length -or variable-length. As a result, programmers can put native programming -language data structures into the database without converting them to -a foreign record format first. Storage and retrieval are very simple, -but the application needs to know what the structure of a key and a -value is in advance. It cannot ask Berkeley DB, because Berkeley DB doesn't know. -<p>This is an important feature of Berkeley DB, and one worth considering more -carefully. On the one hand, Berkeley DB cannot provide the programmer with -any information on the contents or structure of the values that it -stores. The application must understand the keys and values that it -uses. On the other hand, there is literally no limit to the data types -that can be store in a Berkeley DB database. The application never needs to -convert its own program data into the data types that Berkeley DB supports. -Berkeley DB is able to operate on any data type the application uses, no -matter how complex. -<p>Because both keys and values can be up to four gigabytes in length, a -single record can store images, audio streams, or other large data -values. Large values are not treated specially in Berkeley DB. They are -simply broken into page-sized chunks, and reassembled on demand when -the application needs them. Unlike some other database systems, Berkeley DB -offers no special support for binary large objects (BLOBs). -<h3>Not a relational database</h3> -<p>Berkeley DB is not a relational database. -<p>First, Berkeley DB does not support SQL queries. All access to data is through -the Berkeley DB API. Developers must learn a new set of interfaces in order -to work with Berkeley DB. Although the interfaces are fairly simple, they are -non-standard. -<p>SQL support is a double-edged sword. One big advantage of relational -databases is that they allow users to write simple declarative queries -in a high-level language. The database system knows everything about -the data and can carry out the command. This means that it's simple to -search for data in new ways, and to ask new questions of the database. -No programming is required. -<p>On the other hand, if a programmer can predict in advance how an -application will access data, then writing a low-level program to get -and store records can be faster. It eliminates the overhead of query -parsing, optimization, and execution. The programmer must understand -the data representation, and must write the code to do the work, but -once that's done, the application can be very fast. -<p>Second, Berkeley DB has no notion of <i>schema</i> in the way that -relational systems do. Schema is the structure of records in tables, -and the relationships among the tables in the database. For example, in -a relational system the programmer can create a record from a fixed menu -of data types. Because the record types are declared to the system, the -relational engine can reach inside records and examine individual values -in them. In addition, programmers can use SQL to declare relationships -among tables, and to create indexes on tables. Relational engines -usually maintain these relationships and indexes automatically. -<p>In Berkeley DB, the key and value in a record are opaque -to Berkeley DB. They may have a rich -internal structure, but the library is unaware of it. As a result, Berkeley DB -cannot decompose the value part of a record into its constituent parts, -and cannot use those parts to find values of interest. Only the -application, which knows the data structure, can do that. -<p>Berkeley DB does allow programmers to create indexes on tables, and to use -those indexes to speed up searches. However, the programmer has no way -to tell the library how different tables and indexes are related. The -application needs to make sure that they all stay consistent. In the -case of indexes in particular, if the application puts a new record into -a table, it must also put a new record in the index for it. It's -generally simple to write a single function to make the required -updates, but it is work that relational systems do automatically. -<p>Berkeley DB is not a relational system. Relational database systems are -semantically rich and offer high-level database access. Compared to such -systems, Berkeley DB is a high-performance, transactional library for record -storage. It's possible to build a relational system on top of Berkeley DB. In -fact, the popular MySQL relational system uses Berkeley DB for -transaction-protected table management, and takes care of all the SQL -parsing and execution. It uses Berkeley DB for the storage level, and provides -the semantics and access tools. -<h3>Not an object-oriented database</h3> -<p>Object-oriented databases are designed for very tight integration with -object-oriented programming languages. Berkeley DB is written entirely in the -C programming language. It includes language bindings for C++, Java, -and other languages, but the library has no information about the -objects created in any object-oriented application. Berkeley DB never makes -method calls on any application object. It has no idea what methods are -defined on user objects, and cannot see the public or private members -of any instance. The key and value part of all records are opaque to -Berkeley DB. -<p>Berkeley DB cannot automatically page in referenced objects, as some -object-oriented databases do. The object-oriented application programmer -must decide what records are required, and must fetch them by making -method calls on Berkeley DB objects. -<h3>Not a network database</h3> -<p>Berkeley DB does not support network-style navigation among records, as -network databases do. Records in a Berkeley DB table may move around over -time, as new records are added to the table and old ones are deleted. -Berkeley DB is able to do fast searches for records based on keys, but there -is no way to create a persistent physical pointer to a record. -Applications can only refer to records by key, not by address. -<h3>Not a database server</h3> -<p>Berkeley DB is not a standalone database server. It is a library, and runs in -the address space of the application that uses it. If more than one -application links in Berkeley DB, then all can use the same database at the -same time; the library handles coordination among the applications, and -guarantees that they do not interfere with one another. -<p>Recent releases of Berkeley DB allow programmers to compile the library as a -standalone process, and to use RPC stubs to connect to it and to carry -out operations. However, there are some important limitations to this -feature. The RPC stubs provide exactly the same API that the library -itself does. There is no higher-level access provided by the standalone -process. Tuning the standalone process is difficult, since Berkeley DB does -no threading in the library (applications can be threaded, but the -library never creates a thread on its own). -<p>It is possible to build a server application that uses Berkeley DB for data -management. For example, many commercial and open source Lightweight -Directory Access Protocol (LDAP) servers use Berkeley DB for record storage. -LDAP clients connect to these servers over the network. Individual -servers make calls through the Berkeley DB API to find records and return them -to clients. On its own, however, Berkeley DB is not a server. -<table><tr><td><br></td><td width="1%"><a href="../../ref/intro/dbis.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../../ref/toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../../ref/intro/need.html"><img src="../../images/next.gif" alt="Next"></a> -</td></tr></table> -<p><font size=1><a href="http://www.sleepycat.com">Copyright Sleepycat Software</a></font> -</body> -</html> diff --git a/bdb/docs/ref/intro/distrib.html b/bdb/docs/ref/intro/distrib.html deleted file mode 100644 index a5ff52263c2..00000000000 --- a/bdb/docs/ref/intro/distrib.html +++ /dev/null @@ -1,28 +0,0 @@ -<!--$Id: distrib.so,v 10.16 2000/09/22 18:23:58 bostic Exp $--> -<!--Copyright 1997, 1998, 1999, 2000 by Sleepycat Software, Inc.--> -<!--All rights reserved.--> -<html> -<head> -<title>Berkeley DB Reference Guide: What does the Berkeley DB distribution include?</title> -<meta name="description" content="Berkeley DB: An embedded database programmatic toolkit."> -<meta name="keywords" content="embedded,database,programmatic,toolkit,b+tree,btree,hash,hashing,transaction,transactions,locking,logging,access method,access methods,java,C,C++"> -</head> -<body bgcolor=white> -<table><tr valign=top> -<td><h3><dl><dt>Berkeley DB Reference Guide:<dd>Introduction</dl></h3></td> -<td width="1%"><a href="../../ref/intro/what.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../../ref/toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../../ref/intro/where.html"><img src="../../images/next.gif" alt="Next"></a> -</td></tr></table> -<p> -<h1 align=center>What does the Berkeley DB distribution include?</h1> -<p>The Berkeley DB distribution includes complete source code for the Berkeley DB -library, including all three Berkeley DB products and their supporting -utilities, as well as complete documentation in HTML format. -<p>The distribution does not include pre-built binaries or libraries, or -hard-copy documentation.

Decades of research and real-world deployment have produced -countless systems. We need to organize them somehow to reduce the number -of options. -<p>One obvious way to group systems is to use the common labels that -vendors apply to them. The buzzwords here include "network," -"relational," "object-oriented," and "embedded," with some -cross-fertilization like "object-relational" and "embedded network". -Understanding the buzzwords is important. Each has some grounding in -theory, but has also evolved into a practical label for categorizing -systems that work in a certain way. -<p>All database systems, regardless of the buzzwords that apply to them, -provide a few common services. All of them store data, for example. -We'll begin by exploring the common services that all systems provide, -and then examine the differences among the different kinds of systems. -<h3>Data access and data management</h3> -<p>Fundamentally, database systems provide two services. -<p>The first service is <i>data access</i>. Data access means adding -new data to the database (inserting), finding data of interest -(searching), changing data already stored (updating), and removing data -from the database (deleting). All databases provide these services. How -they work varies from category to category, and depends on the record -structure that the database supports. -<p>Each record in a database is a collection of values. For example, the -record for a Web site customer might include a name, email address, -shipping address, and payment information. Records are usually stored -in tables. Each table holds records of the same kind. For example, the -<b>customer</b> table at an e-commerce Web site might store the -customer records for every person who shopped at the site. Often, -database records have a different structure from the structures or -instances supported by the programming language in which an application -is written. As a result, working with records can mean: -<ul type=disc> -<li>using database operations like searches and updates on records; and -<li>converting between programming language structures and database record -types in the application. -</ul> -<p>The second service is <i>data management</i>. Data management is -more complicated than data access. Providing good data management -services is the hard part of building a database system. When you -choose a database system to use in an application you build, making sure -it supports the data management services you need is critical. -<p>Data management services include allowing multiple users to work on the -database simultaneously (concurrency), allowing multiple records to be -changed instantaneously (transactions), and surviving application and -system crashes (recovery). Different database systems offer different -data management services. Data management services are entirely -independent of the data access services listed above. For example, -nothing about relational database theory requires that the system -support transactions, but most commercial relational systems do. -<p>Concurrency means that multiple users can operate on the database at -the same time. Support for concurrency ranges from none (single-user -access only) to complete (many readers and writers working -simultaneously). -<p>Transactions permit users to make multiple changes appear at once. For -example, a transfer of funds between bank accounts needs to be a -transaction because the balance in one account is reduced and the -balance in the other increases. If the reduction happened before the -increase, than a poorly-timed system crash could leave the customer -poorer; if the bank used the opposite order, then the same system crash -could make the customer richer. Obviously, both the customer and the -bank are best served if both operations happen at the same instant. -<p>Transactions have well-defined properties in database systems. They are -<i>atomic</i>, so that the changes happen all at once or not at all. -They are <i>consistent</i>, so that the database is in a legal state -when the transaction begins and when it ends. They are typically -<i>isolated</i>, which means that any other users in the database -cannot interfere with them while they are in progress. And they are -<i>durable</i>, so that if the system or application crashes after -a transaction finishes, the changes are not lost. Together, the -properties of <i>atomicity</i>, <i>consistency</i>, -<i>isolation</i>, and <i>durability</i> are known as the ACID -properties. -<p>As is the case for concurrency, support for transactions varies among -databases. Some offer atomicity without making guarantees about -durability. Some ignore isolatability, especially in single-user -systems; there's no need to isolate other users from the effects of -changes when there are no other users. -<p>Another important data management service is recovery. Strictly -speaking, recovery is a procedure that the system carries out when it -starts up. The purpose of recovery is to guarantee that the database is -complete and usable. This is most important after a system or -application crash, when the database may have been damaged. The recovery -process guarantees that the internal structure of the database is good. -Recovery usually means that any completed transactions are checked, and -any lost changes are reapplied to the database. At the end of the -recovery process, applications can use the database as if there had been -no interruption in service. -<p>Finally, there are a number of data management services that permit -copying of data. For example, most database systems are able to import -data from other sources, and to export it for use elsewhere. Also, most -systems provide some way to back up databases and to restore in the -event of a system failure that damages the database. Many commercial -systems allow <i>hot backups</i>, so that users can back up -databases while they are in use. Many applications must run without -interruption, and cannot be shut down for backups. -<p>A particular database system may provide other data management services. -Some provide browsers that show database structure and contents. Some -include tools that enforce data integrity rules, such as the rule that -no employee can have a negative salary. These data management services -are not common to all systems, however. Concurrency, recovery, and -transactions are the data management services that most database vendors -support. -<p>Deciding what kind of database to use means understanding the data -access and data management services that your application needs. Berkeley DB -is an embedded database that supports fairly simple data access with a -rich set of data management services. To highlight its strengths and -weaknesses, we can compare it to other database system categories. -<h3>Relational databases</h3> -<p>Relational databases are probably the best-known database variant, -because of the success of companies like Oracle. Relational databases -are based on the mathematical field of set theory. The term "relation" -is really just a synonym for "set" -- a relation is just a set of -records or, in our terminology, a table. One of the main innovations in -early relational systems was to insulate the programmer from the -physical organization of the database. Rather than walking through -arrays of records or traversing pointers, programmers make statements -about tables in a high-level language, and the system executes those -statements. -<p>Relational databases operate on <i>tuples</i>, or records, composed -of values of several different data types, including integers, character -strings, and others. Operations include searching for records whose -values satisfy some criteria, updating records, and so on. -<p>Virtually all relational databases use the Structured Query Language, -or SQL. This language permits people and computer programs to work with -the database by writing simple statements. The database engine reads -those statements and determines how to satisfy them on the tables in -the database. -<p>SQL is the main practical advantage of relational database systems. -Rather than writing a computer program to find records of interest, the -relational system user can just type a query in a simple syntax, and -let the engine do the work. This gives users enormous flexibility; they -do not need to decide in advance what kind of searches they want to do, -and they do not need expensive programmers to find the data they need. -Learning SQL requires some effort, but it's much simpler than a -full-blown high-level programming language for most purposes. And there -are a lot of programmers who have already learned SQL. -<h3>Object-oriented databases</h3> -<p>Object-oriented databases are less common than relational systems, but -are still fairly widespread. Most object-oriented databases were -originally conceived as persistent storage systems closely wedded to -particular high-level programming languages like C++. With the spread -of Java, most now support more than one programming language, but -object-oriented database systems fundamentally provide the same class -and method abstractions as do object-oriented programming languages. -<p>Many object-oriented systems allow applications to operate on objects -uniformly, whether they are in memory or on disk. These systems create -the illusion that all objects are in memory all the time. The advantage -to object-oriented programmers who simply want object storage and -retrieval is clear. They need never be aware of whether an object is in -memory or not. The application simply uses objects, and the database -system moves them between disk and memory transparently. All of the -operations on an object, and all its behavior, are determined by the -programming language. -<p>Object-oriented databases aren't nearly as widely deployed as relational -systems. In order to attract developers who understand relational -systems, many of the object-oriented systems have added support for -query languages very much like SQL. In practice, though, object-oriented -databases are mostly used for persistent storage of objects in C++ and -Java programs. -<h3>Network databases</h3> -<p>The "network model" is a fairly old technique for managing and -navigating application data. Network databases are designed to make -pointer traversal very fast. Every record stored in a network database -is allowed to contain pointers to other records. These pointers are -generally physical addresses, so fetching the referenced record just -means reading it from disk by its disk address. -<p>Network database systems generally permit records to contain integers, -floating point numbers, and character strings, as well as references to -other records. An application can search for records of interest. After -retrieving a record, the application can fetch any referenced record -quickly. -<p>Pointer traversal is fast because most network systems use physical disk -addresses as pointers. When the application wants to fetch a record, -the database system uses the address to fetch exactly the right string -of bytes from the disk. This requires only a single disk access in all -cases. Other systems, by contrast, often must do more than one disk read -to find a particular record. -<p>The key advantage of the network model is also its main drawback. The -fact that pointer traversal is so fast means that applications that do -it will run well. On the other hand, storing pointers all over the -database makes it very hard to reorganize the database. In effect, once -you store a pointer to a record, it is difficult to move that record -elsewhere. Some network databases handle this by leaving forwarding -pointers behind, but this defeats the speed advantage of doing a single -disk access in the first place. Other network databases find, and fix, -all the pointers to a record when it moves, but this makes -reorganization very expensive. Reorganization is often necessary in -databases, since adding and deleting records over time will consume -space that cannot be reclaimed without reorganizing. Without periodic -reorganization to compact network databases, they can end up with a -considerable amount of wasted space. -<h3>Clients and servers</h3> -<p>Database vendors have two choices for system architecture. They can -build a server to which remote clients connect, and do all the database -management inside the server. Alternatively, they can provide a module -that links directly into the application, and does all database -management locally. In either case, the application developer needs -some way of communicating with the database (generally, an Application -Programming Interface (API) that does work in the process or that -communicates with a server to get work done). -<p>Almost all commercial database products are implemented as servers, and -applications connect to them as clients. Servers have several features -that make them attractive. -<p>First, because all of the data is managed by a separate process, and -possibly on a separate machine, it's easy to isolate the database server -from bugs and crashes in the application. -<p>Second, because some database products (particularly relational engines) -are quite large, splitting them off as separate server processes keeps -applications small, which uses less disk space and memory. Relational -engines include code to parse SQL statements, to analyze them and -produce plans for execution, to optimize the plans, and to execute -them. -<p>Finally, by storing all the data in one place and managing it with a -single server, it's easier for organizations to back up, protect, and -set policies on their databases. The enterprise databases for large -companies often have several full-time administrators caring for them, -making certain that applications run quickly, granting and denying -access to users, and making backups. -<p>However, centralized administration can be a disadvantage in some cases. -In particular, if a programmer wants to build an application that uses -a database for storage of important information, then shipping and -supporting the application is much harder. The end user needs to install -and administer a separate database server, and the programmer must -support not just one product, but two. Adding a server process to the -application creates new opportunity for installation mistakes and -run-time problems. -<table><tr><td><br></td><td width="1%"><a href="../../ref/intro/data.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../../ref/toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../../ref/intro/dbis.html"><img src="../../images/next.gif" alt="Next"></a> -</td></tr></table> -<p><font size=1><a href="http://www.sleepycat.com">Copyright Sleepycat Software</a></font> -</body> -</html> diff --git a/bdb/docs/ref/intro/what.html b/bdb/docs/ref/intro/what.html deleted file mode 100644 index c8d12069a57..00000000000 --- a/bdb/docs/ref/intro/what.html +++ /dev/null @@ -1,53 +0,0 @@ -<!--$Id: what.so,v 10.22 2000/09/22 18:23:59 bostic Exp $--> -<!--Copyright 1997, 1998, 1999, 2000 by Sleepycat Software, Inc.--> -<!--All rights reserved.--> -<html> -<head> -<title>Berkeley DB Reference Guide: What other services does Berkeley DB provide?</title> -<meta name="description" content="Berkeley DB: An embedded database programmatic toolkit."> -<meta name="keywords" content="embedded,database,programmatic,toolkit,b+tree,btree,hash,hashing,transaction,transactions,locking,logging,access method,access methods,java,C,C++"> -</head> -<body bgcolor=white> -<table><tr valign=top> -<td><h3><dl><dt>Berkeley DB Reference Guide:<dd>Introduction</dl></h3></td> -<td width="1%"><a href="../../ref/intro/need.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../../ref/toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../../ref/intro/distrib.html"><img src="../../images/next.gif" alt="Next"></a> -</td></tr></table> -<p> -<h1 align=center>What other services does Berkeley DB provide?</h1> -<p>Berkeley DB also provides core database services to developers.

In order to lock a file, pages in -the file, or records in the file, we must create a unique ID that -can be used as the object to be locked in calls to the lock manager. -Under normal operation, that object is a 28-byte value, created by -the concatenation of a unique file identifier, a page or record number, -and an object type (page or record). -<p>In a transaction-protected environment, database create and delete -operations are recoverable and single-threaded.

This is most easily accomplished by using a locker -ID of a different length than the values used by Berkeley DB. -<p>All of the access methods other than Queue use a simple -multiple-reader/single writer page locking scheme. The standard -read/write locks (<b>DB_LOCK_READ</b> and <b>DB_LOCK_WRITE</b>) and -conflict matrix, as described in <a href="../../ref/lock/stdmode.html">Standard lock modes</a> are used. An operation that returns data (e.g., -<a href="../../api_c/db_get.html">DB->get</a>, <a href="../../api_c/dbc_get.html">DBcursor->c_get</a>) obtains a read lock on all the pages -accessed while locating the requested record. When an update operation -is requested (e.g., <a href="../../api_c/db_put.html">DB->put</a>, <a href="../../api_c/dbc_del.html">DBcursor->c_del</a>), the page containing -the updated (or new) data is write locked. As read-modify-write cycles -are quite common and are deadlock prone under normal circumstances, the -Berkeley DB interfaces allow the application to specify the <a href="../../api_c/dbc_get.html#DB_RMW">DB_RMW</a> flag, -which causes operations to immediately obtain a writelock, even though -they are only reading the data. While this may reduce concurrency -somewhat, it reduces the probability of deadlock. -<p>The Queue access method does not hold long term page locks. -Instead, page locks are held only long enough to locate records or to change -metadata on a page, and record locks are held for the appropriate duration. -In the presence of transactions, record locks are held until transaction -commit. -For Berkeley DB operations, record locks are held until operation -completion and for DBC operations, record locks are held until -subsequent records are returned or the cursor is closed. -<p>Under non-transaction operation, the access methods do not normally hold -locks across calls to the Berkeley DB interfaces. The one exception to this -rule is when cursors are used. As cursors maintain a position in a file, -they must hold locks across calls and will, in fact, hold locks until the -cursor is closed. Furthermore, each cursor is assigned its own unique -locker ID when it is created, so cursor operations can conflict with one -another. (Each cursor is assigned its own locker ID because Berkeley DB handles -may be shared by multiple threads of control. The Berkeley DB library cannot -identify which operations are performed by which threads of control, and -it must ensure that two different threads of control are not -simultaneously modifying the same data structure. By assigning each -cursor its own locker, two threads of control sharing a handle cannot -inadvertently interfere with each other. -<p>This has important implications. If a single thread of control opens two -cursors or uses a combination of cursor and non-cursor operations, these -operations are performed on behalf of different lockers. Conflicts that -arise between these different lockers may not cause actual deadlocks, but -can, in fact, permanently block the thread of control. For example, -assume that an application creates a cursor and uses it to read record A. -Now assume a second cursor is opened and the application attempts to write -record A using the second cursor. Unfortunately, the first cursor has a -read lock so the second cursor cannot obtain its write lock. However, -that read lock is held by the same thread of control, so if we block -waiting for the write lock, the read lock can never be released. This -might appear to be a deadlock from the application's perspective, but -Berkeley DB cannot identify it as such because it has no knowledge of which -lockers belong to which threads of control. For this reason, application -designers are encouraged to close cursors as soon as they are done with -them. -<p>Complicated operations that require multiple cursors (or combinations of -cursor and non-cursor operations) can be performed in two ways. First, -they may be performed within a transaction, in which case all operations -lock on behalf of the designated locker ID. Alternatively, the -<a href="../../api_c/dbc_dup.html">DBcursor->c_dup</a> function duplicates a cursor, using the same locker ID as -the originating cursor. There is no way to achieve this duplication -functionality through the DB handle calls, but any DB call can be -implemented by one or more calls through a cursor. -<p>When the access methods use transactions, many of these problems disappear. -The transaction ID is used as the locker ID for all operations performed -on behalf of the transaction. This means that the application may open -multiple cursors on behalf of the same transaction and these cursors will -all share a common locker ID. This is safe because transactions cannot -span threads of control, so the library knows that two cursors in the same -transaction cannot modify the database concurrently. -<p>As mentioned earlier, most of the Berkeley DB access methods use page level -locking. During Btree traversal, lock-coupling is used to traverse the -tree. Note that the tree traversal that occurs during an update operation -can also use lock-coupling; it is not necessary to retain locks on -internal Btree pages even if the item finally referenced will be updated. -Even in the presence of transactions, locks obtained on internal pages of -the Btree may be safely released as the traversal proceeds. This greatly -improves concurrency. The only time internal locks become crucial is when -internal pages are split or merged. When traversing duplicate data items -for a key, the lock on the key value also acts as a lock on all duplicates -of that key.

The page-overhead for Hash databases is 26 -bytes and the page-overhead-for-two-entries is 6 bytes. -<p>As an example, using an 8K page size, there are 8166 bytes of useful space -on each page: -<p><blockquote><pre>8166 = (8192 - 26)</pre></blockquote> -<p>The total <b>bytes-of-data</b> is an easy calculation: it is the number -of key/data pairs plus the overhead required to store each pair on a page. -In this case that's 6 bytes per pair. So, assuming 60,000,000 key/data -pairs, each of which is 8 bytes long, there are 1320000000 bytes, or -roughly 1.23GB, of total data: -<p><blockquote><pre>1320000000 = 60000000 * ((16 + 6))</pre></blockquote> -<p>The total pages of data, <b>n-pages-of-data</b>, is the -<b>bytes-of-data</b> divided by the <b>useful-bytes-per-page</b>. In -this example, there are 161646 pages of data. -<p><blockquote><pre>161646 = 1320000000 / 8166</pre></blockquote> -<p>The total bytes of disk space for the database is <b>n-pages-of-data</b> -multiplied by the <b>page-size</b>. In the example, the result is -1324204032 bytes, or roughly 1.23GB. -<p><blockquote><pre>1324204032 = 161646 * 8192</pre></blockquote> -<p>Now, let's assume that the application specified a fill factor explicitly. -The fill factor indicates the target number of items to place on a single -page (a fill factor might reduce the utilization of each page, but it can -be useful in avoiding splits and preventing buckets from becoming too -large. Using our estimates above, each item is 22 bytes (16 + 6) and -there are 8166 useful bytes on a page (8192 - 26). That means that, on -average, you can fit 371 pairs per page. -<p><blockquote><pre>371 = 8166 / 22</pre></blockquote> -<p>However, let's assume that the application designer knows that while most -items are 8 bytes, they can sometimes be as large as 10 and it's very -important to avoid overflowing buckets and splitting. Then, the -application might specify a fill factor of 314. -<p><blockquote><pre>314 = 8166 / 26</pre></blockquote> -<p>With a fill factor of 314, then the formula for computing database size -is: -<p><blockquote><pre>npages = npairs / pairs-per-page</pre></blockquote> -<p>or 191082. -<p><blockquote><pre>191082 = 60000000 / 314</pre></blockquote> -<p>At 191082 pages, the total database size would be 1565343744 or 1.46GB. -<p><blockquote><pre>1565343744 = 191082 * 8192 </pre></blockquote> -<p>There are a few additional caveats with respect to Hash databases. This -discussion assumes that the hash function does a good job of evenly -distributing keys among hash buckets. If the function does not do this, -you may find your table growing significantly larger than you expected. -Secondly, in order to provide support for Hash databases co-existing with -other databases in a single file, pages within a Hash database are -allocated in power-of-2 chunks. That means that a Hash database with 65 -buckets will take up as much space as a Hash database with 128 buckets; -each time the Hash database grows beyond its current power-of-two number -of buckets, it allocates space for the next power-of-two buckets. This -space may be sparsely allocated in the file system, but the files will -appear to be their full size. Finally, because of this need for -contiguous allocation, overflow pages and duplicate pages can be allocated -only at specific points in the file, and this too can lead to sparse hash -tables. -<table><tr><td><br></td><td width="1%"><a href="../../ref/program/byteorder.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../../ref/toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../../ref/program/compatible.html"><img src="../../images/next.gif" alt="Next"></a> -</td></tr></table> -<p><font size=1><a href="http://www.sleepycat.com">Copyright Sleepycat Software</a></font> -</body> -</html> diff --git a/bdb/docs/ref/program/environ.html b/bdb/docs/ref/program/environ.html deleted file mode 100644 index 7f56109b5d7..00000000000 --- a/bdb/docs/ref/program/environ.html +++ /dev/null @@ -1,33 +0,0 @@ -<!--$Id: environ.so,v 10.17 2000/03/18 21:43:16 bostic Exp $--> -<!--Copyright 1997, 1998, 1999, 2000 by Sleepycat Software, Inc.--> -<!--All rights reserved.--> -<html> -<head> -<title>Berkeley DB Reference Guide: Environment variables</title> -<meta name="description" content="Berkeley DB: An embedded database programmatic toolkit."> -<meta name="keywords" content="embedded,database,programmatic,toolkit,b+tree,btree,hash,hashing,transaction,transactions,locking,logging,access method,access methods,java,C,C++"> -</head> -<body bgcolor=white> - <a name="2"><!--meow--></a> -<table><tr valign=top> -<td><h3><dl><dt>Berkeley DB Reference Guide:<dd>Programmer Notes</dl></h3></td> -<td width="1%"><a href="../../ref/program/errorret.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../../ref/toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../../ref/program/mt.html"><img src="../../images/next.gif" alt="Next"></a> -</td></tr></table> -<p> -<h1 align=center>Environment variables</h1> -<p>The Berkeley DB library uses the following environment variables: -<p><dl compact> -<p><dt>DB_HOME<dd>If the environment variable DB_HOME is set, it is used as part of -<a href="../../ref/env/naming.html">File Naming</a>. -Note, for the DB_HOME variable to take effect, either the -<a href="../../api_c/env_open.html#DB_USE_ENVIRON">DB_USE_ENVIRON</a> or <a href="../../api_c/env_open.html#DB_USE_ENVIRON_ROOT">DB_USE_ENVIRON_ROOT</a> flags must be -specified to <a href="../../api_c/env_open.html">DBENV->open</a>. -<p><dt>TMPDIR, TEMP, TMP, TempFolder<dd>The TMPDIR, TEMP, TMP and TempFolder environment variables are all -checked as locations in which to create temporary files.

The function will be called with -the "op" parameter set to DB_TXN_ABORT when a transaction that wrote the -log record aborts and with DB_TXN_FORWARD_ROLL and DB_TXN_BACKWARD_ROLL -during recovery. The actions for DB_TXN_ABORT and DB_TXN_BACKWARD_ROLL -should generally be the same. For example, in the access methods, each -page contains the log sequence number of the most recent log record that -describes a modification to the page. When the access method changes a -page it writes a log record describing the change and including the the -LSN that was on the page before the change. This LSN is referred to as -the previous LSN. The recovery functions read the page described by a -log record and compare the log sequence number (LSN) on the page to the -LSN they were passed. If the page LSN is less than the passed LSN and -the operation is undo, no action is necessary (because the modifications -have not been written to the page). If the page LSN is the same as the -previous LSN and the operation is redo, then the actions described are -reapplied to the page. If the page LSN is equal to the passed LSN and -the operation is undo, the actions are removed from the page; if the page -LSN is greater than the passed LSN and the operation is redo, no further -action is necessary. If the action is a redo and the LSN on the page is -less than the previous LSN in the log record this is an error, since this -could only happen if some previous log record was not processed. -<p>Please refer to the internal recovery functions in the Berkeley DB library -(found in files named XXX_rec.c) for examples of how recovery functions -should work. -<h3>Non-conformant Logging</h3> -<p>If your application cannot conform to the default logging and recovery -structure, then you will have to create your own logging and recovery -functions explicitly. -<p>First, you must decide how you will dispatch your records. Encapsulate -this algorithm in a dispatch function that is passed to <a href="../../api_c/env_open.html">DBENV->open</a>. -The arguments for the dispatch function are as follows: -<p><dl compact> -<p><dt>dbenv<dd>The environment handle returned by <a href="../../api_c/env_create.html">db_env_create</a>. -<p><dt>rec<dd>The record being recovered. -<p><dt>lsn<dd>The log sequence number of the record to be recovered. -<p><dt>op<dd>Indicates what operation of recovery is needed (openfiles, abort, forward roll -or backward roll). -<p><dt>info<dd>An opaque value passed to your function during system recovery. -</dl> -<p>When you abort a transaction, <a href="../../api_c/txn_abort.html">txn_abort</a> will read the last log -record written for the aborting transaction and will then call your -dispatch function.

The company -collects license fees for certain uses of the software and sells support -and services. -<h2> -History -</h2> -<p> -Berkeley DB began as a new implementation of a hash access method -to replace both -<tt>hsearch</tt> -and the various -<tt>dbm</tt> -implementations -(<tt>dbm</tt> from AT&T, -<tt>ndbm</tt> -from Berkeley, and -<tt>gdbm</tt> -from the GNU project). -In 1990 Seltzer and Yigit produced a package called Hash to do this -<a href="#Selt91">[Selt91]</a>. -<p> -The first general release of Berkeley DB, in 1991, -included some interface changes and a new B+tree access method. -At roughly the same time, Seltzer and Olson -developed a prototype transaction -system based on Berkeley DB, called LIBTP <a href="#Selt92">[Selt92]</a>, -but never released the code. -<p> -The 4.4BSD UNIX release included Berkeley DB 1.85 in 1992. -Seltzer and Bostic maintained the code in the early 1990s -in Berkeley and in Massachusetts. -Many users adopted the code during this period. -<p> -By mid-1996, -users wanted commercial support for the software. -In response, Bostic and Seltzer formed Sleepycat Software. -The company enhances, distributes, and -supports Berkeley DB and supporting software and documentation. -Sleepycat released version 2.1 of Berkeley DB in mid-1997 -with important new features, including -support for concurrent access to databases. -The company makes about three commercial releases a year, -and most recently shipped version 2.8. -<h2> -Overview of Berkeley DB -</h2> -<p> -The C interfaces in Berkeley DB permit -<tt>dbm</tt>-style -record management -for databases, -with significant extensions to handle duplicate data items elegantly, -to deal with concurrent access, and to provide transactional -support so that multiple changes can be simultaneously committed -(so that they are made permanent) or rolled back (so that the -database is restored to its state at the beginning of the transaction). -<p> -C++ and Java interfaces provide a small set of classes for -operating on a database. The main class in both cases is called -<tt>Db</tt>, -and provides methods that encapsulate the -<tt>dbm</tt>-style -interfaces that the C interfaces provide. -<p> -Tcl and Perl interfaces allow developers working in those languages -to use Berkeley DB in their applications. -Bindings for both languages are included in the distribution. -<p> -Developers may compile their applications and link in Berkeley DB -statically or dynamically. -<h2> -How Berkeley DB is used -</h2> -<p> -The Berkeley DB library supports concurrent access to databases. -It can be linked -into standalone applications, into a collection of cooperating applications, -or into servers that handle requests and do database operations on -behalf of clients. -<p> -Compared to using a standalone database management system, Berkeley -DB is easy to understand and simple to use. The -software stores and retrieves records, which consist of key/value pairs. -Keys are used to locate items and can be any data type or structure -supported by the programming language. -<p> -The programmer can provide the functions that Berkeley DB uses to -operate on keys. -For example, -B+trees can use a custom comparison function, -and the Hash access method can use a custom hash function. -Berkeley DB uses default functions if none are supplied. -Otherwise, Berkeley DB does not examine or interpret either keys -or values in any way. -Values may be arbitrarily long. -<p> -It is also important to understand what Berkeley DB is not. -It is not a database server that handles network requests. It is not an -SQL engine that executes queries. It is not a relational or object-oriented -database management system. -<p> -It is possible to build any of those on top of Berkeley DB, -but the package, as distributed, -is an embedded database engine. It has been designed -to be portable, small, fast, and reliable. -<h2> -Applications that use Berkeley DB -</h2> -<p> -Berkeley DB is embedded in a variety of proprietary and Open Source -software packages. -This section highlights a few of the products that use it. -<p> -Directory servers, which do data storage and retrieval using the -Local Directory Access Protocol (LDAP), provide naming and directory -lookup service on local-area networks. -This service is, -essentially, -database query and update, -but uses a simple protocol rather than SQL or ODBC. -Berkeley DB is the embedded data manager in the majority of deployed -directory servers today, -including LDAP servers from Netscape, -MessageDirect (formerly Isode), -and others. -<p> -Berkeley DB is also embedded in a large number of mail servers. -Intermail, -from Software.com, -uses Berkeley DB as a message store -and as the backing store for its directory server. -The sendmail server -(including both the commercial Sendmail Pro offering from Sendmail, -Inc. and the version distributed by sendmail.org) -uses Berkeley DB to store aliases and other information. -Similarly, -Postfix (formerly VMailer) uses Berkeley DB -to store administrative information. -<p> -In addition, -Berkeley DB is embedded in a wide variety of other software products. -Example applications include managing access control lists, -storing user keys in a public-key infrastructure, -recording machine-to-network-address mappings in address servers, -and storing configuration and device information in video -post-production software. -<p> -Finally, -Berkeley DB is a part of many other Open Source software packages -available on the Internet. -For example, -the software is embedded in the Apache Web server and the Gnome desktop. -<h1> -Access Methods -</h1> -<p> -In database terminology, an access method is the disk-based structure -used to store data and the operations available on that structure. -For example, many database systems support a B+tree access method. -B+trees allow equality-based lookups (find keys equal to some constant), -range-based lookups (find keys between two constants) and record -insertion and deletion. -<p> -Berkeley DB supports three access methods: B+tree, -Extended Linear Hashing (Hash), -and Fixed- or Variable-length Records (Recno). -All three operate on records composed of a key and a data value. -In the B+tree and Hash access methods, keys can have arbitrary structure. -In the Recno access method, each record is assigned a record number, which -serves as the key. -In all the access methods, the -value can have arbitrary structure. -The programmer can supply comparison or hashing functions for keys, -and Berkeley DB stores and retrieves values without -interpreting them. -<p> -All of the access methods use the host filesystem as a backing store. -<h2> -Hash -</h2> -<p> -Berkeley DB includes a Hash access method that implements extended -linear hashing <a href="#Litw80">[Litw80]</a>. -Extended linear hashing adjusts the hash function as the hash -table grows, attempting to keep all buckets underfull in the steady -state. -<p> -The Hash access method supports insertion and deletion of records and -lookup by exact match only. Applications may iterate over all records -stored in a table, but the order in which they are returned is undefined. -<h2> -B+tree -</h2> -<p> -Berkeley DB includes a B+tree <a href="#Come79">[Come79]</a> access method. -B+trees store records of key/value pairs in leaf pages, -and pairs of (key, child page address) at internal nodes. -Keys in the tree are stored in sorted order, -where the order is determined by the comparison function supplied when the -database was created. -Pages at the leaf level of the tree include pointers -to their neighbors to simplify traversal. B+trees support lookup by -exact match (equality) or range (greater than or equal to a key). -Like Hash tables, B+trees support record insertion, -deletion, and iteration over all records in the tree. -<p> -As records are inserted and pages in the B+tree fill up, they are split, -with about half the keys going into a new peer page at the same level in -the tree. -Most B+tree implementations leave both nodes half-full after a split. -This leads to poor performance in a common case, where the caller inserts -keys in order. -To handle this case, Berkeley DB keeps track of the insertion order, -and splits pages unevenly to keep pages fuller. -This reduces tree size, yielding better search performance and smaller -databases. -<p> -On deletion, empty pages are coalesced by reverse splits -into single pages. -The access method does no other page balancing on insertion -or deletion. -Keys are not moved among pages at every update -to keep the tree well-balanced. While this could improve search times -in some cases, the additional code complexity leads to slower updates and -is prone to deadlocks. -<p> -For simplicity, Berkeley DB B+trees do no prefix compression of keys -at internal or leaf nodes. -<h2> -Recno -</h2> -<p> -Berkeley DB includes a fixed- or variable-length record access method, -called -<i>Recno</i>. -The Recno access method assigns logical record numbers to each -record, -and can search for and update records by record number. -Recno is able, -for example, -to load a text file into a database, -treating each line as a record. -This permits fast searches by line number for applications like -text editors <a href="#Ston82">[Ston82]</a>. -<p> -Recno is actually built -on top of the B+tree access method and provides a simple interface -for storing sequentially-ordered data values. -The Recno access method generates keys internally. -The programmer's view of the values is that -they are numbered sequentially from one. -Developers can choose to have records automatically renumbered -when lower-numbered records are added or deleted. -In this case, new keys can be inserted between existing keys. -<h1> -Features -</h1> -<p> -This section describes important features of Berkeley DB. -In general, -developers can choose which features are useful to them, -and use only those that are required by their application. -<p> -For example, -when an application opens a database, it can declare the degree of -concurrency and recovery that it requires. Simple stand-alone applications, -and in particular ports of applications that used -<tt>dbm</tt> -or one of its -variants, generally do not require concurrent access or crash recovery. -Other applications, such as enterprise-class database management systems -that store sales transactions or other critical data, need full -transactional service. Single-user operation is faster than multi-user -operation, since no overhead is incurred by locking. Running with -the recovery system disabled is faster than running with it enabled, -since log records need not be written when changes are made to the -database. -<p> -In addition, some core subsystems, including the locking system and -the logging facility, -can be used outside the context of the access methods as well. -Although few users have chosen to do so, it is possible to -use only the lock manager in Berkeley DB to control concurrency -in an application, without using any of the standard database services. -Alternatively, the caller can integrate locking of non-database resources -with Berkeley DB's transactional two-phase locking system, to impose -transaction semantics on objects outside the database. -<h2> -Programmatic interfaces -</h2> -<p> -Berkeley DB defines a simple API for database management. -The package does not include industry-standard -programmatic interfaces such as Open Database Connectivity (ODBC), -Object Linking and Embedding for Databases (OleDB), or Structured -Query Language (SQL). These interfaces, while useful, were -designed to promote interoperability of database systems, and not -simplicity or performance. -<p> -In response to customer demand, -Berkeley DB 2.5 introduced support for the XA standard <a href="#Open94">[Open94]</a>. -XA permits Berkeley DB to participate in distributed transactions -under a transaction processing monitor like Tuxedo from BEA Systems. -Like XA, other standard interfaces can be built on top of the -core system. -The standards do not belong inside Berkeley DB, -since not all applications need them. -<h2> -Working with records -</h2> -<p> -A database user may need to search for particular keys in a database, -or may simply want to browse available records. -Berkeley DB supports both keyed access, -to find one or more records with a given key, -or sequential access, -to retrieve all the records in the database one at a time. -The order of the records returned during sequential scans -depends on the access method. -B+tree and Recno databases return records in sort order, -and Hash databases return them in apparently random order. -<p> -Similarly, -Berkeley DB defines simple interfaces for inserting, -updating, -and deleting records in a database. -<h2> -Long keys and values -</h2> -<p> -Berkeley DB manages keys and values as large as -2<sup>32</sup> bytes. -Since the time required to copy a record is proportional to its size, -Berkeley DB includes interfaces that operate on partial records. -If an application requires only part of a large record, -it requests partial record retrieval, -and receives just the bytes that it needs. -The smaller copy saves both time and memory. -<p> -Berkeley DB allows the programmer to define the data types of -keys and values. -Developers use any type expressible in the programming language. -<h2> -Large databases -</h2> -<p> -A single database managed by Berkeley DB can be up to 2<sup>48</sup> -bytes, -or 256 petabytes, -in size. -Berkeley DB uses the host filesystem as the backing store -for the database, -so large databases require big file support from the operating system. -Sleepycat Software has customers using Berkeley DB -to manage single databases in excess of 100 gigabytes. -<h2> -Main memory databases -</h2> -<p> -Applications that do not require persistent storage can create -databases that exist only in main memory. -These databases bypass the overhead imposed by the I/O system -altogether. -<p> -Some applications do need to use disk as a backing store, -but run on machines with very large memory. -Berkeley DB is able to manage very large shared memory regions -for cached data pages, -log records, -and lock management. -For example, -the cache region used for data pages may be gigabytes in size, -reducing the likelihood that any read operation will need to -visit the disk in the steady state. -The programmer declares the size of the cache region at -startup. -<p> -Finally, many operating systems provide memory-mapped file services -that are much faster than their general-purpose file system -interfaces. -Berkeley DB can memory-map its database files for read-only database use. -The application operates on records stored directly on the pages, -with no cache management overhead. -Because the application gets pointers directly into the -Berkeley DB pages, -writes cannot be permitted. -Otherwise, -changes could bypass the locking and logging systems, -and software errors could corrupt the database. -Read-only applications can use Berkeley DB's memory-mapped -file service to improve performance on most architectures. -<h2> -Configurable page size -</h2> -<p> -Programmers declare the size of the pages used by their access -methods when they create a database. -Although Berkeley DB provides reasonable defaults, -developers may override them to control system performance. -Small pages reduce the number of records that fit on a single page. -Fewer records on a page means that fewer records are locked when -the page is locked, -improving concurrency. -The per-page overhead is proportionally higher with smaller pages, -of course, -but developers can trade off space for time as an application requires. -<h2> -Small footprint -</h2> -<p> -Berkeley DB is a compact system. -The full package, including all access methods, recoverability, -and transaction support -is roughly 175K of text space on common architectures. -<h2> -Cursors -</h2> -<p> -In database terminology, a cursor is a pointer into an access method -that can be called iteratively to return records in sequence. Berkeley -DB includes cursor interfaces for all access methods. This permits, -for example, users to traverse a B+tree and view records in order. -Pointers to records in cursors are persistent, so that once fetched, -a record may be updated in place. Finally, cursors support access to -chains of duplicate data items in the various access methods. -<h2> -Joins -</h2> -<p> -In database terminology, -a join is an operation that spans multiple separate -tables (or in the case of Berkeley DB, multiple separate DB files). -For example, a company may store information about its customers -in one table and information about sales in another. An application -will likely want to look up sales information by customer name; this -requires matching records in the two tables that share a common -customer ID field. -This combining of records from multiple tables is called a join. -<p> -Berkeley DB includes interfaces for joining two or more tables. -<h2> -Transactions -</h2> -<p> -Transactions have four properties <a href="#Gray93">[Gray93]</a>: -<ul> -<li> -They are atomic. That is, all of the changes made in a single -transaction must be applied at the same instant or not at all. -This permits, for example, the transfer of money between two -accounts to be accomplished, by making the reduction of the -balance in one account and the increase in the other into a -single, atomic action. -</li> -<li> -They must be consistent. That is, changes to the database -by any transaction cannot leave the database in an illegal -or corrupt state. -</li> -<li> -They must be isolatable. Regardless of the number of users -working in the database at the same time, every user must have -the illusion that no other activity is going on. -</li> -<li> -They must be durable. Even if the disk that stores the database -is lost, it must be possible to recover the database to its last -transaction-consistent state. -</li> -</ul> -<p> -This combination of properties -- atomicity, consistency, isolation, and -durability -- is referred to as ACIDity in the literature. Berkeley DB, -like most database systems, provides ACIDity using a collection of core -services. -<p> -Programmers can choose to use Berkeley DB's transaction services -for applications that need them. -<h3> -Write-ahead logging -</h3> -<p> -Programmers can enable the logging system when they start up Berkeley DB. -During a transaction, -the application makes a series of changes to the database. -Each change is captured in a log entry, -which holds the state of the database record -both before and after the change. -The log record is guaranteed -to be flushed to stable storage before any of the changed data pages -are written. -This behavior -- writing the log before the data pages -- is called -<i>write-ahead logging</i>. -<p> -At any time during the transaction, -the application can -<i>commit</i>, -making the changes permanent, -or -<i>roll back</i>, -cancelling all changes and restoring the database to its -pre-transaction state. -If the application -rolls back the transaction, then the log holds the state of all -changed pages prior to the transaction, and Berkeley DB simply -restores that state. -If the application commits the transaction, -Berkeley DB writes the log records to disk. -In-memory copies of the data pages already reflect the changes, -and will be flushed as necessary during normal processing. -Since log writes are sequential, but data page -writes are random, this improves performance. -<h3> -Crashes and recovery -</h3> -<p> -Berkeley DB's write-ahead log is used by the transaction -system to commit or roll back transactions. -It also gives the recovery system the information that -it needs to protect against data loss or corruption -from crashes. -Berkeley DB is able to survive application crashes, -system crashes, -and even catastrophic failures like the loss of a hard -disk, -without losing any data. -<p> -Surviving crashes requires data stored in several different places. -During normal processing, -Berkeley DB has copies of active log records and recently-used -data pages in memory. -Log records are flushed to the log disk when transactions commit. -Data pages trickle out to the data disk as pages move through -the buffer cache. -Periodically, -the system administrator backs up the data disk, -creating a safe copy of the database at a particular instant. -When the database is backed up, -the log can be truncated. -For maximum robustness, -the log disk and data disk should be separate devices. -<p> -Different system failures can destroy memory, -the log disk, -or the data disk. -Berkeley DB is able to survive the loss of any one -of these repositories -without losing any committed transactions. -<p> -If the computer's memory is lost, -through an application or operating system crash, -then the log holds all committed transactions. -On restart, -the recovery system rolls the log forward against -the database, -reapplying any changes to on-disk pages that were in memory at the -time of the crash. -Since the log contains pre- and post-change state for -transactions, -the recovery system also uses the log to restore any pages to -their original state if they were modified by transactions -that never committed. -<p> -If the data disk is lost, -the system administrator can restore the most recent copy from backup. -The recovery system will roll the entire log forward against -the original database, -reapplying all committed changes. -When it finishes, -the database will contain every change made by every -transaction that ever committed. -<p> -If the log disk is lost, -then the recovery system can use the in-memory copies of -log entries to roll back any uncommitted transactions, -flush all in-memory database pages to the data disk, -and shut down gracefully. -At that point, -the system administrator can back up the database disk, -install a new log disk, -and restart the system. -<h3> -Checkpoints -</h3> -<p> -Berkeley DB includes a checkpointing service that interacts -with the recovery system. -During normal processing, -both the log and the database are changing continually. -At any given instant, -the on-disk versions of the two are not guaranteed to be consistent. -The log probably contains changes that are not yet in the database. -<p> -When an application makes a -<i>checkpoint</i>, -all committed changes in the log up to that point -are guaranteed to be present on the data disk, -too. -Checkpointing is moderately expensive during normal processing, -but limits the time spent recovering from crashes. -<p> -After an application or operating system crash, -the recovery system only needs to go back two checkpoints -to start rolling the log forward. -(One checkpoint is not far enough. -The recovery system cannot be sure that the most recent -checkpoint completed -- -it may have been interrupted by the crash that forced the -recovery system to run in the first place.) -Without checkpoints, -there is no way to be sure how long restarting after a crash will take. -With checkpoints, -the restart interval can be fixed by the programmer. -Recovery processing can be guaranteed to complete in a second or two. -<p> -Software crashes are much more common than disk failures. -Many developers want to guarantee that software bugs do not destroy data, -but are willing to restore from tape, -and to tolerate a day or two of lost work, -in the unlikley event of a disk crash. -With Berkeley DB, -programmers may truncate the log at checkpoints. -As long as the two most recent checkpoints are present, -the recovery system can guarantee that no committed transactions -are lost after a software crash. -In this case, -the recovery system does not require that the log and the -data be on separate devices, -although separating them can still improve performance -by spreading out writes. -<h3> -Two-phase locking -</h3> -<p> -Berkeley DB provides a service known as two-phase locking. -In order to reduce the likelihood of deadlocks and to guarantee ACID -properties, database systems manage locks in two phases. First, during -the operation of a transaction, they acquire locks, but never release -them. Second, at the end of the transaction, they release locks, but -never acquire them. In practice, most database systems, including Berkeley -DB, acquire locks on demand over the course of the transaction, then -flush the log, then release all locks. -<p> -Berkeley DB can lock entire database files, which correspond to tables, -or individual pages in them. -It does no record-level locking. -By shrinking the page size, -however, -developers can guarantee that every page holds only a small -number of records. -This reduces contention. -<p> -If locking is enabled, -then read and write operations on a database acquire two-phase locks, -which are held until the transaction completes. -Which objects are locked and the order of lock acquisition -depend on the workload for each transaction. -It is possible for two or more transactions to deadlock, -so that each is waiting for a lock that is held by another. -<p> -Berkeley DB detects deadlocks and automatically rolls back -one of the transactions. -This releases the locks that it held -and allows the other transactions to continue. -The caller is notified that its transaction did not complete, -and may restart it. -Developers can specify the deadlock detection interval -and the policy to use in choosing a transaction to roll back. -<p> -The two-phase locking interfaces are separately callable by applications -that link Berkeley DB, though few users have needed to use that facility -directly. -Using these interfaces, -Berkeley DB provides a fast, -platform-portable locking system for general-purpose use. -It also lets users include non-database objects in a database transaction, -by controlling access to them exactly as if they were inside the database. -<p> -The Berkeley DB two-phase locking facility is built on the fastest correct -locking primitives that are supported by the underlying architecture. -In the current implementation, this means that the locking system is -different on the various UNIX platforms, and is still more different -on Windows NT. In our experience, the most difficult aspect of performance -tuning is finding the fastest locking primitives that work correctly -on a particular architecture and then integrating the new -interface with the several that we already support. -<p> -The world would be a better place if the operating systems community -would uniformly implement POSIX locking primitives and would guarantee -that acquiring an uncontested lock was a fast operation. -Locks must work both among threads in a single process -and among processes. -<h2> -Concurrency -</h2> -<p> -Good performance under concurrent operation is a critical design point -for Berkeley DB. Although Berkeley DB is itself not multi-threaded, -it is thread-safe, and runs well in threaded applications. -Philosophically, -we view the use of threads and the choice of a threads package -as a policy decision, -and prefer to offer mechanism (the ability to run threaded or not), -allowing applications to choose their own policies. -<p> -The locking, logging, and buffer pool subsystems all use shared memory -or other OS-specific sharing facilities to communicate. Locks, buffer -pool fetches, and log writes behave in the same way across threads in -a single process as they do across different processes on a single -machine. -<p> -As a result, concurrent database applications may start up a new process -for every single user, may create a single server which spawns a new -thread for every client request, or may choose any policy in between. -<p> -Berkeley DB has been carefully designed to minimize contention -and maximize concurrency. -The cache manager allows all threads or processes to benefit from -I/O done by one. -Shared resources must sometimes be locked for exclusive access -by one thread of control. -We have kept critical sections small, -and are careful not to hold critical resource locks across -system calls that could deschedule the locking thread or process. -Sleepycat Software has customers with hundreds of concurrent -users working on a single database in production. -<h1> -Engineering Philosophy -</h1> -<p> -Fundamentally, Berkeley DB is a collection of access methods with -important facilities, like logging, locking, and transactional access -underlying them. In both the research and the commercial world, -the techniques for building systems like Berkeley DB have been well-known -for a long time. -<p> -The key advantage of Berkeley DB is the careful attention that has been -paid to engineering details throughout its life. We have carefully -designed the system so that the core facilities, like locking and I/O, -surface the right interfaces and are otherwise opaque to the caller. -As programmers, we understand the value of simplicity and have worked -hard to simplify the interfaces we surface to users of the -database system. -<p> -Berkeley DB avoids limits in the code. It places no practical limit -on the size of keys, values, or databases; they may grow to occupy -the available storage space. -<p> -The locking and logging subsystems have been carefully crafted to -reduce contention and improve throughput by shrinking or eliminating -critical sections, and reducing the sizes of locked regions and log -entries. -<p> -There is nothing in the design or implementation of Berkeley DB that -pushes the state of the art in database systems. Rather, we have been -very careful to get the engineering right. The result is a system that -is superior, as an embedded database system, to any other solution -available. -<p> -Most database systems trade off simplicity for correctness. Either the -system is easy to use, or it supports concurrent use and survives system -failures. Berkeley DB, because of its careful design and implementation, -offers both simplicity and correctness. -<p> -The system has a small footprint, -makes simple operations simple to carry out (inserting a new record takes -just a few lines of code), and behaves correctly in the face of heavy -concurrent use, system crashes, and even catastrophic failures like loss -of a hard disk. -<h1> -The Berkeley DB 2.x Distribution -</h1> -<p> -Berkeley DB is distributed in source code form from -<a href="http://www.sleepycat.com">www.sleepycat.com</a>. -Users are free to download and build the software, and to use it in -their applications. -<h2> -What is in the distribution -</h2> -<p> -The distribution is a compressed archive file. -It includes the source code for the Berkeley DB library, -as well as documentation, test suites, and supporting utilities. -<p> -The source code includes build support for all supported platforms. -On UNIX systems Berkeley DB uses the GNU autoconfiguration tool, -<tt>autoconf</tt>, -to identify the system and to build the library -and supporting utilities. -Berkeley DB includes specific build environments for other platforms, -such as VMS and Windows. -<h3> -Documentation -</h3> -<p> -The distributed system includes documentation in HTML format. -The documentation is in two parts: -a UNIX-style reference manual for use by programmers, -and a reference guide which is tutorial in nature. -<h3> -Test suite -</h3> -<p> -The software also includes a complete test suite, written in Tcl. -We believe that the test suite is a key advantage of Berkeley DB -over comparable systems. -<p> -First, the test suite allows users who download and build the software -to be sure that it is operating correctly. -<p> -Second, the test suite allows us, like other commercial developers -of database software, to exercise the system thoroughly at every -release. When we learn of new bugs, we add them to the test suite. -We run the test suite continually during development cycles, and -always prior to release. The result is a much more reliable system -by the time it reaches beta release. -<h2> -Binary distribution -</h2> -<p> -Sleepycat makes compiled libraries and general binary distributions available -to customers for a fee. -<h2> -Supported platforms -</h2> -<p> -Berkeley DB runs on any operating system with a -POSIX 1003.1 interface <a href="#IEEE96">[IEEE96]</a>, -which includes virtually every UNIX system. -In addition, -the software runs on VMS, -Windows/95, -Windows/98, -and Windows/NT. -Sleepycat Software no longer supports deployment on sixteen-bit -Windows systems. -<h1> -Berkeley DB 2.x Licensing -</h1> -<p> -Berkeley DB 2.x is distributed as an Open Source product. The software -is freely available from us at our Web site, and in other media. Users -are free to download the software and build applications with it. -<p> -The 1.x versions of Berkeley DB were covered by the UC Berkeley copyright -that covers software freely redistributable in source form. When -Sleepycat Software was formed, we needed to draft a license consistent -with the copyright governing the existing, older software. Because -of important differences between the UC Berkeley copyright and the GPL, -it was impossible for us to use the GPL. -A second copyright, with -terms contradictory to the first, simply would not have worked. -<p> -Sleepycat wanted to continue Open Source development of Berkeley DB -for several reasons. -We agree with Raymond <a href="#Raym98">[Raym98]</a> and others that Open -Source software is typically of higher quality than proprietary, -binary-only products. -Our customers benefit from a community of developers who -know and use Berkeley DB, -and can help with application design, -debugging, -and performance tuning. -Widespread distribution and use of the source code tends to -isolate bugs early, -and to get fixes back into the distributed system quickly. -As a result, -Berkeley DB is more reliable. -Just as importantly, -individual users are able to contribute new features -and performance enhancements, -to the benefit of everyone who uses Berkeley DB. -From a business perspective, -Open Source and free distribution of the -software creates share for us, and gives us a market into which -we can sell products and services. -Finally, making the source code -freely available reduces our support load, since customers can -find and fix bugs without recourse to us, in many cases. -<p> -To preserve the Open Source heritage of the older Berkeley DB code, -we drafted a new license governing the distribution of Berkeley DB -2.x. We adopted terms from the GPL that make it impossible to -turn our Open Source code into proprietary code owned by someone else. -<p> -Briefly, the terms governing the use and distribution of Berkeley DB -are: -<ul> -<li> -your application must be internal to your site, or -</li> -<li> -your application must be freely redistributable in source form, or -</li> -<li> -you must get a license from us. -</li> -</ul> -<p> -For customers who prefer not to distribute Open Source products, -we sell licenses to use and extend Berkeley DB at a reasonable cost. -<p> -We work hard to accommodate the needs of the Open Source community. -For example, -we have crafted special licensing arrangements with Gnome -to encourage its use and distribution of Berkeley DB. -<p> -Berkeley DB conforms to the Open Source definition <a href="#Open99">[Open99]</a>. -The license has -been carefully crafted to keep the product available as an Open Source -offering, -while providing enough of a return on our investment to fund continued -development and support of the product. The current license has -created a business capable of funding three years of development on -the software that simply would not have happened otherwise. -<h1> -Summary -</h1> -<p> -Berkeley DB offers a unique collection of features, targeted squarely -at software developers who need simple, reliable database management -services in their applications. Good design and implementation and -careful engineering throughout make the software better than many -other systems. -<p> -Berkeley DB is an Open Source product, available at -<a href="http://www.sleepycat.com">www.sleepycat.com</a>. -for download. The distributed system includes everything needed to -build and deploy the software or to port it to new systems. -<p> -Sleepycat Software distributes Berkeley DB under a license agreement -that draws on both the UC Berkeley copyright and the GPL. The license -guarantees that Berkeley DB will remain an Open Source product and -provides Sleepycat with opportunities to make money to fund continued -development on the software. -<h1> -References

Introduction</h2> - -Embedded systems provide a combination of opportunities and challenges -in application and system configuration and management. -As an embedded system is most often dedicated to a single application or -small set of tasks, the operating conditions of the system are -typically better understood than those of general purpose computing -environments. -Similarly, as embedded systems are dedicated to a small set of tasks, -one would expect that the software to manage them should be small -and simple. -On the other hand, once an embedded system is deployed, it must -continue to function without interruption and without administrator -intervention. -<p> -Database administration consists of two components, -initial configuration and ongoing maintenance. -Initial configuration consists of database design, manifestation, -and tuning. -The instantiation of the design includes decomposing the design -into tables, relations, or objects and designating proper indices -and their implementations (e.g., Btrees, hash tables, etc.). -Tuning a design requires selecting a location for the log and -data files, selecting appropriate database page sizes, specifying -the size of in-memory caches, and specifying the limits of -multi-threading and concurrency. -As embedded systems define a specific environment and set of tasks, -requiring expertise during the initial system -configuration process is acceptable, and we focus our efforts on -the ongoing maintenance of the system. -In this way, our emphasis differs from other projects such as -Microsoft's AutoAdmin project <a href="#Chaud982">[3]</a>, and the "no-knobs" -administration that is identified as an area of important future -research by the Asilomar authors<a href="#Bern98">[1]</a>. -<p> -In this paper, we focus on what the authors -of the Asilomar report call "gizmo" databases <a href="#Bern98"> [1]</a>, -databases -that reside in devices such as smart cards, toasters, or telephones. -The key characteristics of such databases are that their -functionality is completely transparent to users, no one ever -performs explicit database operations or -database maintenance, the database may crash at any time and -must recover instantly, the device may undergo a hard reset at -any time, requiring that the database return to its initial -state, and the semantic integrity of the database must be maintained -at all times. -In Section 2, we provide more detail on the sorts of tasks -typically performed by database administrators (DBAs) that must -be automated in an embedded system. -<p> -The rest of this paper is structured as follows. -In Section 2, we outline the requirements for embedded database support. -In Section 3, we discuss how Berkeley DB -is conducive to the hands-off management -required in embedded systems. -In Section 4, we discuss novel features that -enhance Berkeley -DB's suitability for the embedded applications. -In Section 5, we discuss issues of footprint size. -In Section 6 we discuss related work, and we conclude -in Section 7. - -<h2>2. Embedded Database Requirements</h2> -Historically, much of the commercial database industry has been driven -by the requirements of high performance online transaction -processing (OLTP), complex query processing, and the industry -standard benchmarks that have emerged (e.g., TPC-C <a href="#TPCC">[9]</a>, -TPC-D <a href="#TPCD">[10]</a>) to -allow for system comparisons. -As embedded systems typically perform fairly simple queries, -such metrics are not nearly as relevant for embedded database -systems as are ease of maintenance, robustness, and small footprint. -Of these three requirements, robustness and ease of maintenance -are the key issues. -Users must trust the data stored in their devices and must not need -to manually perform anything resembling system administration in order -to get their unit to work properly. -Fortunately, ease of use and robustness are important side -effects of simplicity and good design. -These, in turn, lead to a small size, providing the third -requirement of an embedded system. -<h3>2.1 The User Perspective</h3> -<p> -In the embedded database arena, it is the ongoing maintenance tasks -that must be automated, not necessarily the initial system configuration. -There are five tasks -that are traditionally performed by DBAs, -but must be performed automatically -in embedded database systems. -These tasks are -log archival and reclamation, -backup, -data compaction/reorganization, -automatic and rapid recovery, and -reinitialization from scratch. -<P> -Log archival and backup are tightly coupled. -Database backups are part of any -large database installation, and log archival is analogous to incremental -backup. -It is not clear what the implications of backup and archival are in -an embedded system. -Consumers do not back up their VCRs or refrigerators, yet they do -(or should) back up their personal computers or personal digital -assistants. -For the remainder of this paper, we assume that backups, in some form, -are required for gizmo databases (imagine having to reprogram, manually, -the television viewing access pattern learned by some set-top television -systems today). -Furthermore, we require that those backups are nearly instantaneous or -completely transparent, -as users should not be aware that their gizmos are being backed up -and should not have to explicitly initiate such backups. -<p> -Data compaction or reorganization has traditionally required periodic -dumping and restoration of -database tables and the recreation of indices. -In an embedded system, such reorganization must happen automatically. -<p> -Recovery issues are similar in embedded and traditional environments -with a few exceptions. -While a few seconds or even a minute recovery is acceptable -for a large server installation, no one is willing to wait -for their telephone or television to reboot. -As with archival, recovery must be nearly instantaneous in an embedded product. -Secondly, it is often the case that a system will be completely -reinitialized, rather than simply rebooted. -In this case, the embedded database must be restored to its initial -state, freeing all its resources. -This is not typically a requirement of large server systems. -<h3>2.2 The Developer Perspective</h3> -<p> -In addition to the maintenance-free operation required of the -embedded systems, there are a number of requirements that fall -out of the constrained resources typically found in the "gizmos" -using gizmo databases. These requirements are: -small footprint, -short code-path, -programmatic interface for tight application coupling and -to avoid the overhead (in both time and size) of -interfaces such as SQL and ODBC, -application configurability and flexibility, -support for complete memory-resident operation (e.g., these systems -must run on gizmos without file systems), and -support for multi-threading. -<p> -A small footprint and short code-path are self-explanatory, however -what is not as obvious is that the programmatic interface requirement -is the logical result of them. -Traditional interfaces such as ODBC and SQL add significant -size overhead and frequently add multiple context/thread switches -per operation, not to mention several IPC calls. -An embedded product is less likely to require the complex -query processing that SQL enables. -Instead, in the embedded space, the ability for an application -to configure the database for the specific tasks in question -is more important than a general query interface. -<p> -As some systems do not provide storage other than RAM and ROM, -it is essential that an embedded database work seemlessly -in memory-only environments. -Similarly, many of today's embedded operating systems provide a -single address space architecture, so a simple, multi-threaded -capability is essential for application requiring any concurrency. -<p> -In general, embedded applications run on gizmos whose native -operating system support varies tremendously. -For example, the embedded OS may or may -not support user-level processing or multi-threading. -Even if it does, a particular embedded -application may or may not need it. -Not all applications need more than one thread of control. -An embedded database must provide mechanisms to developers -without deciding policy. -For example, the threading model in an application is a matter of policy, -and depends -not on the database software, but on the hardware, operating -system, and the application's feature set. -Therefore, the data manager must provide for the use of multi-threading, -but not require it. - -<h2>3. Berkeley DB: A Database for Embedded Systems</h2> -Berkeley DB is the result of implementing database functionality -using the UNIX tool-based philosophy. -The current Berkeley DB package, as distributed by Sleepycat -Software, is a descendant of the hash and btree access methods -distributed with 4.4BSD and its descendents. -The original package (referred to as DB-1.85), -while intended as a public domain replacement for dbm and -its followers (e.g., ndbm, gdbm, etc), rapidly became widely -used as an efficient, easy-to-use data store. -It was incorporated into a number of Open Source packages including -Perl, Sendmail, Kerberos, and the GNU C-library. -<p> -Versions 2.X and higher are distributed by Sleepycat Software and -add functionality for concurrency, logging, transactions, and -recovery. -Each piece of additional functionality is implemented as an independent -module, which means that the subsystems can be used outside the -context of Berkeley DB. For example, the locking subsystem can -easily be used to implement locking for a non-DB application and -the shared memory buffer pool can be used for any application -caching data in main memory. -This subsystem design allows a designer to pick and choose -the functionality necessary for the application, minimizing -memory footprint and maximizing performance. -This addresses the small footprint and short code-path criteria -mentioned in the previous section. -<p> -As Berkeley DB grew out of a replacement for dbm, its primary -implementation language has always been C and its interface has -been programmatic. The C interface is the native interface, -unlike many database systems where the programmatic API is simply -a layer on top of an already-costly query interface (e.g. embedded -SQL). -Berkeley DB's heritage is also apparent in its data model; it has -none. -The database stores unstructured key/data pairs, specified as -variable length byte strings. -This leaves schema design and representation issues the responsibility -of the application, which is ideal for an embedded environment. -Applications retain full control over specification of their data -types, representation, index values, and index relationships. -In other words, Berkeley DB provides a robust, high-performance, -keyed storage system, not a particular database management system. -We have designed for simplicity and performance, trading off -complex, general purpose support that is better encapsulated in -applications. -<p> -Another element of Berkeley DB's programmatic interface is its -customizability; applications can specify Btree comparison and -prefix compression functions, hash functions, error routines, -and recovery models. -This means that embedded applications can tailor the underlying -database to best suit their data demands. -Similarly, the utilities traditionally bundled with a database -manager (e.g., recovery, dump/restore, archive) are implemented -as tiny wrapper programs around library routines. This means -that it is not necessary to run separate applications for the -utilities. Instead, independent threads can act as utility -daemons, or regular query threads can perform utility functions. -Many of the current products built on Berkeley DB are bundled as -a single large server with independent threads that perform functions -such as checkpoint, deadlock detection, and performance monitoring. -<p> -As mentioned earlier, living in an embedded environment requires -flexible management of storage. -Berkeley DB does not require any preallocation of disk space -for log or data files. -While many commercial database systems take complete control -of a raw device, Berkeley DB uses a normal file system, and -can therefore, safely and easily share a data space with other -programs. -All databases and log files are native files of the host environment, -so whatever utilities are provided by the environment can be used -to manage database files as well. -<p> -Berkeley DB provides three different memory models for its -management of shared information. -Applications can use the IEEE Std 1003.1b-1993 (POSIX) <tt>mmap</tt> -interface to share -data, they can use system shared memory, as frequently provided -by the shmget family of interfaces, or they can use per-process -heap memory (e.g., malloc). -Applications that require no permanent storage and do not provide -shared memory facilities can still use Berkeley DB by requesting -strictly private memory and specifying that all databases be -memory-resident. -This provides pure-memory operation. -<p> -Lastly, Berkeley DB is designed for rapid startup -- recovery can -happen automatically as part of system initialization. -This means that Berkeley DB works correctly in environments where -gizmos are suddenly shut down and restarted. - -<h2>4. Extensions for Embedded Environments </h2> -While the Berkeley DB library has been designed for use in -embedded systems, all the features described above are useful -in more conventional systems as well. -In this section, we discuss a number of features and "automatic -knobs" that are specifically geared -toward the more constrained environments found in gizmo databases. - -<h3>4.1 Automatic compression</h3> -Following the programmatic interface design philosophy, we -support application-specific (or default) compression routines. -These can be geared toward the particular data types present -in the application's dataset, thus providing better compression -than a general purpose routine. -Note that the application could instead specify an encryption -function and create encrypted databases instead of compressed ones. -Alternately, the application might specify a function that performs -both compression and encryption. -<p> -As applications are also permitted to specify comparison and hash -functions, the application can chose to organize its data based -either on uncompressed and clear-text data or compressed and encrypted -data. -If the application indicates that data should be compared in its -processed form (i.e., compressed and encrypted), then the compression -and encryption are performed on individual data items and the in-memory -representation retains these characteristics. -However, if the application indicates that data should be compared in -its original form, then entire pages are transformed upon being read -into or written out of the main memory buffer cache. -These two alternatives provide the flexibility to trade space -and security for performance. - -<h3>4.2 In-memory logging & transactions</h3> -One of the four key properties of transaction systems is durability. -This means that transaction systems are designed for permanent storage -(most commonly disk). However, as mentioned above, embedded systems -do not necessarily contain any such storage. -Nevertheless, transactions can be useful in this environment to -preserve the semantic integrity of the underlying storage. -Berkeley DB optionally provides logging functionality and -transaction support regardless of whether the database and logs -are on disk or in memory. - -<h3>4.3 Remote Logs</h3> -While we do not expect users to backup their television sets and -toasters, it is conceivable that a set-top box provided by a -cable carrier should, in fact, be backed up by that cable carrier. -The ability to store logs remotely can provide "information appliance" -functionality, and can also be used in conjunction with local logs -to enhance reliability. -Furthermore, remote logs provide for catastrophic recovery, e.g., loss -of the gizmo, destruction of the gizmo, etc. - -<h3>4.4 Application References to Database Buffers</h3> - -Typically, when data is returned to the user, it must be copied -from the data manager's buffer cache (or data page) into the -application's memory. -However, in an embedded environment, the robustness of the -total software package is of paramount importance, not the -isolation between the application and the data manager. -As a result, it is possible for the data manager to avoid -copies by giving applications direct references to data items -in a shared memory cache. -This is a significant performance optimization that can be -allowed when the application and data manager are tightly -integrated. - -<h3>4.5 Recoverable database creation/deletion</h3> - -In a conventional database management system, the creation of -database tables (relations) and indices are heavyweight operations -that are not recoverable. -This is not acceptable in a complex embedded environment where -instantaneous recovery and robust operation in the face of -all types of database operations is essential. -While Berkeley DB files can be removed using normal file system -utilities, we provide transaction protected utilities that -allow us to recover both database creation and deletion. - -<h3>4.6 Adaptive concurrency control</h3> -The Berkeley DB package uses page-level locking by default. -This trades off fine grain concurrency control for simplicity -during recovery. (Finer grain concurrency control can be -obtained by reducing the page size in the database.) -However, when multiple threads/processes perform page-locking -in the presence of writing operations, there is the -potential for deadlock. -As some environments do not need or desire the overhead of -logging and transactions, it is important to provide the -ability for concurrent access without the potential for -deadlock. -<p> -Berkeley DB provides an option to perform coarser grain, -deadlock-free locking. -Rather than locking on pages, locking is performed at the -interface to the database. -Multiple readers or a single writer are allowed to be -active in the database at any instant in time, with -conflicting requests queued automatically. -The presence of cursors, through which applications can both -read and write data, complicates this design. -If a cursor is currently being used for reading, but will later -be used to write, the system will be deadlock prone if no -special precautions are taken. -To handle this situation, we require that, when a cursor is -created, the application specify any future intention to write. -If there is an intention to write, the cursor is granted an -intention-to-write lock which does not conflict with readers, -but does conflict with other intention-to-write locks and write -locks. -The end result is that the application is limited to a single -potentially writing cursor accessing the database at any point -in time. -<p> -Under periods of low contention (but potentially high throughput), -the normal page-level locking provides the best overall throughput. -However, as contention rises, so does the potential for deadlock. -As some cross-over point, switching to the less concurrent, but -deadlock-free locking protocol will result in higher throughput -as operations must never be retried. -Given the operating conditions of an embedded database manager, -it is useful to make this change automatically as the system -itself detects high contention. - -<h3>4.7 Adaptive synchronization</h3> - -In addition to the logical locks that protect the integrity of the -database pages, Berkeley DB must synchronize access to shared memory -data structures, such as the lock table, in-memory buffer pool, and -in-memory log buffer. -Each independent module uses a single mutex to protect its shared -data structures, under the assumption that operations that require -the mutex are very short and the potential for conflict is -low. -Unfortunately, in highly concurrent environments with multiple processors -present, this assumption is not always true. -When this assumption becomes invalid (that is, we observe significant -contention for the subsystem mutexes), we can switch over to a finer-grained -concurrency model for the mutexes. -Once again, there is a performance trade-off. Fine-grain mutexes -impose a penalty of approximately 25% (due to the increased number -of mutexes required for each operation), but allow for higher throughput. -Using fine-grain mutexes under low contention would cause a decrease -in performance, so it is important to monitor the system carefully, -so that the change can be executed only when it will increase system -throughput without jeopardizing latency. - -<h2>5. Footprint of an Embedded System</h2> -While traditional systems compete on price-performance, the -embedded players will compete on price, features, and footprint. -The earlier sections have focused on features; in this section -we focus on footprint. -<p> -Oracle reports that Oracle Lite 3.0 requires 350 KB to 750 KB -of memory and approximately 2.5 MB of hard disk space <a href="#Oracle">[7]</a>. -This includes drivers for interfaces such as ODBC and JDBC. -In contrast, Berkeley DB ranges in size from 75 KB to under 200 KB, -foregoing heavyweight interfaces such as ODBC and JDBC and -providing a variety of deployed sizes that can be used depending -on application needs. At the low end, applications requiring -a simple single-user access method can choose from either extended -linear hashing, B+ trees, or record-number based retrieval and -pay only the 75 KB space requirement. -Applications requiring all three access methods will observe the -110 KB footprint. -At the high end, a fully recoverable, high-performance system -occupies less than a quarter megabyte of memory. -This is a system you can easily incorporate in your toaster oven. -Table 1 shows the per-module break down of the entire Berkeley DB -library. Note that this does not include memory used to cache database -pages. - -<table border> -<tr><th colspan=4>Object sizes in bytes</th></tr> -<tr><th align=left>Subsystem</th><th align=center>Text</th><th align=center>Data</th><th align=center>Bss</th></tr> -<tr><td>Btree-specific routines</td><td align=right>28812</td><td align=right>0</td><td align=right>0</td></tr> -<tr><td>Recno-specific routines</td><td align=right>7211</td><td align=right>0</td><td align=right>0</td></tr> -<tr><td>Hash-specific routines</td><td align=right>23742</td><td align=right>0</td><td align=right>0</td></tr> -<tr><td colspan=4></td></tr> -<tr><td>Memory Pool</td><td align=right>14535</td><td align=right>0</td><td align=right>0</td></tr> -<tr><td>Access method common code</td><td align=right>23252</td><td align=right>0</td><td align=right>0</td></tr> -<tr><td>OS compatibility library</td><td align=right>4980</td><td align=right>52</td><td align=right>0</td></tr> -<tr><td>Support utilities</td><td align=right>6165</td><td align=right>0</td><td align=right>0</td></tr> -<tr><td colspan=4></td></tr> -<tr><th>All modules for Btree access method only</th><td align=right>77744</td><td align=right>52</td><td align=right>0</td></tr> -<tr><th>All modules for Recno access method only</th><td align=right>84955</td><td align=right>52</td><td align=right>0</td></tr> -<tr><th>All modules for Hash access method only</th><td align=right>72674</td><td align=right>52</td><td align=right>0</td></tr> -<tr><td colspan=4></td></tr> -<tr><th align=left>All Access Methods</th><td align=right>108697</td><td align=right>52</td><td align=right>0</td></tr> -<tr><td colspan=4><br></td></tr> -<tr><td>Locking</td><td align=right>12533</td><td align=right>0</td><td align=right>0</td></tr> -<tr><td colspan=4></td></tr> -<tr><td>Recovery</td><td align=right>26948</td><td align=right>8</td><td align=right>4</td></tr> -<tr><td>Logging</td><td align=right>37367</td><td align=right>0</td><td align=right>0</td></tr> -<tr><td colspan=4></td></tr> -<tr><th align=left>Full Package</th><td align=right>185545</td><td align=right>60</td><td align=right>4</td></tr> -<tr><br></tr> -</table> - -<h2>6. Related Work</h2> - -Every three to five years, leading researchers in the database -community convene to identify future directions in database -research. -They produce a report of this meeting, named for the year and -location of the meeting. -The most recent of these reports, the 1998 Asilomar report, -identifies the embedded database market as one of the -high growth areas in database research <a href="#Bern98">[1]</a>. -Not surprisingly, market analysts identify the embedded database -market as a high-growth area in the commercial sector as well <a href="#Host98"> -[5]</a>. -<p> -The Asilomar report identifies a new class of database applications, which they -term "gizmo" databases, small databases embedded in tiny mobile -appliances, e.g., smart-cards, telephones, personal digital assistants. -Such databases must be self-managing, secure and reliable. -Thus, the idea is that gizmo databases require plug and play data -management with no database administrator (DBA), no human settable -parameters, and the ability to adapt to changing conditions. -More specifically, the Asilomar authors claim that the goal is -self-tuning, including defining the physical DB design, the -logical DB design, and automatic reports and utilities <a href="#Bern98">[1]</a> -To date, -few researchers have accepted this challenge, and there is a dearth -of research literature on the subject. -<p> -Our approach to embedded database administration is fundamentally -different than that described by the Asilomar authors. -We adopt their terminology, but view the challenge in supporting -gizmo databases to be that of self-sustenance <em>after</em> initial -deployment. Therefore, we find it, not only acceptable, but -desirable to assume that application developers control initial -database design and configuration. To the best of our knowledge, -none of the published work in this area addresses this approach. -<p> -As the research community has not provided guidance in this -arena, most work in embedded database administration has fallen -to the commercial vendors. -These vendors fall into two camps, companies selling databases -specifically designed for embedding or programmatic access -and the major database vendors (e.g., Oracle, Informix, Sybase). -<p> -The embedded vendors all acknowledge the need for automatic -administration, but fail to identify precisely how their -products actually accomplish this. -A notable exception is Interbase whose white paper -comparison with Sybase and Microsoft's SQL servers -explicitly address features of maintenance ease. -Interbase claims that as they use no log files, there is -no need for log reclamation, checkpoint tuning, or other -tasks associated with log management. However, Interbase -uses Transaction Information Pages, and it is unclear -how these are reused or reclaimed <a href="#Interbase">[6]</a>. -Additionally, with a log-free system, they must use -a FORCE policy (write all pages to disk at commit), -as defined by Haerder and Reuter <a href="#Haerder">[4]</a>. This has -serious performance consequences for disk-based systems. -The approach described in this paper does use logs and -therefore requires log reclamation, -but provides hooks so the application may reclaim logs -safely and programmatically. -While Berkeley DB does require checkpoints, the goal of -tuning the checkpoint interval is to bound recovery time. -Since the checkpoint interval in Berkeley DB can be expressed -by the amount of log data written, it requires no tuning. -The application designer sets a target recovery time, and -selects the amount of log data that can be read in that interval -and specifies the checkpoint interval appropriately. Even as -load changes, the time to recover does not. -<p> -The backup approaches taken by Interbase and Berkeley DB -are similar in that they both allow online backup, but -rather different in their affect on transactions running -during backup. As Interbase performs backups as transactions -<a href="#Interbase">[6]</a>, concurrent queries can suffer potentially long -delays. Berkeley DB uses native operating system system utilities -and recovery for backups, so there is no interference with -concurrent activity, other than potential contention on disk -arms. -<p> -There are a number of database vendors selling in -the embedded market (e.g., Raima, -Centura, Pervasive, Faircom), but none highlight -the special requirements of embedded database -applications. -On the other end of the spectrum, the major vendors, -Oracle, Sybase, Microsoft, are all becoming convinced -of the importance of the embedded market. -As mentioned earlier, Oracle has announced its -Oracle Lite server for embedded use. -Sybase has announced its UltraLite platform for "application-optimized, -high-performance, SQL database engine for professional -application developers building solutions for mobile and embedded platforms." -<a href="#Sybase">[8]</a>. -We believe that SQL is incompatible with the -gizmo database environment or truly embedded systems for which Berkeley -DB is most suitable. -Microsoft research is taking a different approach, developing -technology to assist in automating initial database design and -index specification <a href="#Chaud98">[2]</a><a href="#Chaud982">[3]</a>. -As mentioned earlier, we believe that such configuration is, not only -acceptable in the embedded market, but desirable so that applications -can tune their database management for the target environment. -<h2>7. Conclusions</h2> -The coming wave of embedded systems poses a new set of challenges -for data management. -The traditional server-based, big footprint systems designed for -high performance on big iron are not the right approach in this -environment. -Instead, application developers need small, fast, versatile systems -that can be tailored to a specific environment. -In this paper, we have identified several of the key issues in -providing these systems and shown how Berkeley DB provides -many of the characteristics necessary for such applications. - -<h2>8.

In addition, at least -one transaction checkpoint must be performed after all existing -transactions have been committed or aborted. -<p><dt>The easy way:<dd>It greatly simplifies matters that recovery may be performed regardless -of whether recovery strictly needs to be performed, that is, it is not -an error to run recovery on a database where no recovery is necessary. -Because of this fact, it is almost invariably simpler to ignore the -above rules about shutting an application down cleanly, and simply run -recovery each time a thread of control accessing a database environment -fails for any reason, as well as before accessing any database -environment after system reboot. -</dl> -<p>There are two common ways to build transactionally protected Berkeley DB -applications. The most common way is as a single, usually -multi-threaded, process. This architecture is simplest because it -requires no monitoring of other threads of control. When the -application starts, it opens and potentially creates the environment, -runs recovery (whether it was needed or not), and then opens its -databases. From then on, the application can create new threads of -control as it chooses. All threads of control share the open Berkeley DB -DB_ENV and DB handles. In this model, databases are -rarely opened or closed when more than a single thread of control is -running, that is, they are opened when only a single thread is running, -and closed after all threads but one have exited. The last thread of -control to exit closes the databases and the environment. -<p>An alternative way to build Berkeley DB applications is as a set of -cooperating processes, which may or may not be multi-threaded. This -architecture is more complicated. -<p>First, this architecture requires that the order in which threads of -control are created and subsequently access the Berkeley DB environment be -controlled, because recovery must be single-threaded. The first thread -of control to access the environment must run recovery, and no other -thread should attempt to access the environment until recovery is -complete. (Note that this ordering requirement does not apply to -environment creation without recovery. If multiple threads attempt to -create a Berkeley DB environment, only one will perform the creation and the -others will join the already existing environment.) -<p>Second, this architecture requires that threads of control be monitored. -If any thread of control that owns Berkeley DB resources exits, without first -cleanly discarding those resources, recovery is usually necessary. -Before running recovery, all threads using the Berkeley DB environment must -relinquish all of their Berkeley DB resources (it does not matter if they do -so gracefully or because they are forced to exit). Then recovery can -be run and the threads of control continued or re-started. -<p>We have found that the safest way to structure groups of cooperating -processes is to first create a single process (often a shell script) -that opens/creates the Berkeley DB environment and runs recovery, and which -then creates the processes or threads that will actually perform work. -The initial thread has no further responsibilities other than to monitor -the threads of control it has created, to ensure that none of them -unexpectedly exits. If one exits, the initial process then forces all -of the threads of control using the Berkeley DB environment to exit, runs -recovery, and restarts the working threads of control. -<p>If it is not practical to have a single parent for the processes sharing -a Berkeley DB environment, each process sharing the environment should log -their connection to and exit from the environment in some fashion that -permits a monitoring process to detect if a thread of control may have -potentially acquired Berkeley DB resources and never released them. -<p>Obviously, it is important that the monitoring process in either case -be as simple and well-tested as possible as there is no recourse should -it fail. -<table><tr><td><br></td><td width="1%"><a href="../../ref/transapp/term.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../../ref/toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../../ref/transapp/env_open.html"><img src="../../images/next.gif" alt="Next"></a> -</td></tr></table> -<p><font size=1><a href="http://www.sleepycat.com">Copyright Sleepycat Software</a></font> -</body> -</html> diff --git a/bdb/docs/ref/transapp/archival.html b/bdb/docs/ref/transapp/archival.html deleted file mode 100644 index 2e88158504d..00000000000 --- a/bdb/docs/ref/transapp/archival.html +++ /dev/null @@ -1,149 +0,0 @@ -<!--$Id: archival.so,v 10.41 2000/12/05 20:36:25 bostic Exp $--> -<!--Copyright 1997, 1998, 1999, 2000 by Sleepycat Software, Inc.--> -<!--All rights reserved.--> -<html> -<head> -<title>Berkeley DB Reference Guide: Database and log file archival</title> -<meta name="description" content="Berkeley DB: An embedded database programmatic toolkit."> -<meta name="keywords" content="embedded,database,programmatic,toolkit,b+tree,btree,hash,hashing,transaction,transactions,locking,logging,access method,access methods,java,C,C++"> -</head> -<body bgcolor=white> - <a name="2"><!--meow--></a> -<table><tr valign=top> -<td><h3><dl><dt>Berkeley DB Reference Guide:<dd>Transaction Protected Applications</dl></h3></td> -<td width="1%"><a href="../../ref/transapp/checkpoint.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../../ref/toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../../ref/transapp/logfile.html"><img src="../../images/next.gif" alt="Next"></a> -</td></tr></table> -<p> -<h1 align=center>Database and log file archival</h1> - <a name="3"><!--meow--></a> -<p>The third component of the administrative infrastructure, archival for -catastrophic recovery, concerns the recoverability of the database in -the face of catastrophic failure. Recovery after catastrophic failure -is intended to minimize data loss when physical hardware has been -destroyed, for example, loss of a disk that contains databases or log -files. While the application may still experience data loss in this -case, it is possible to minimize it. -<p>First, you may want to periodically create snapshots (i.e., backups) of -your databases to make it possible to recover from catastrophic failure. -These snapshots are either a standard backup which creates a consistent -picture of the databases as of a single instant in time, or an on-line -backup (also known as a <i>hot</i> backup), which creates a -consistent picture of the databases as of an unspecified instant during -the period of time when the snapshot was made. The advantage of a hot -backup is that applications may continue to read and write the databases -while the snapshot is being taken. The disadvantage of a hot backup is -that more information must be archived, and recovery based on a hot -backup is to an unspecified time between the start of the backup and -when the backup is completed. -<p>Second, after taking a snapshot, you should periodically archive the -log files being created in the environment. It is often helpful to -think of database archival in terms of full and incremental filesystem -backups. A snapshot is a full backup, while the periodic archival of -the current log files is an incremental. For example, it might be -reasonable to take a full snapshot of a database environment weekly or -monthly, and then archive additional log files daily. Using both the -snapshot and the log files, a catastrophic crash at any time can be -recovered to the time of the most recent log archival, a time long after -the original snapshot. -<p>To create a standard backup of your database that can be used to recover -from catastrophic failure, take the following steps: -<p><ol> -<p><li>Commit or abort all on-going transactions. -<p><li>Force an environment checkpoint (see <a href="../../utility/db_checkpoint.html">db_checkpoint</a> for more -information). -<p><li>Stop writing your databases until the backup has completed.

This description in the log file is guaranteed -to be written to stable storage before the database pages that were -changed are written to stable storage.

This means that Berkeley DB can fail if the underlying -filesystem fails in some unrecoverable way. Otherwise, the interface -requirements here are simple: the system call that Berkeley DB uses to flush -data to disk (normally <b>fsync</b>(2)), must guarantee that all the -information necessary for a file's recoverability has been written to -stable storage before it returns to Berkeley DB, and that no possible -application or system crash can cause that file to be unrecoverable. -<p>In addition, Berkeley DB implicitly uses the interface between the operating -system and the underlying hardware. The interface requirements here are -not as simple. -<p>First, it is necessary to consider the underlying page size of the Berkeley DB -databases. The Berkeley DB library performs all database writes using the page -size specified by the application. These pages are not checksummed and -Berkeley DB assumes that they are written atomically. This means that if the -operating system performs filesystem I/O in different sized blocks than -the database page size, it may increase the possibility for database -corruption. For example, assume that Berkeley DB is writing 32KB pages for a -database and the operating system does filesystem I/O in 16KB blocks. If -the operating system writes the first 16KB of the database page -successfully, but crashes before being able to write the second 16KB of -the database, the database has been corrupted and this corruption will -not be detected during recovery. For this reason, it may be important -to select database page sizes that will be written as single block -transfers by the underlying operating system. -<p>Second, it is necessary to consider the behavior of the system's underlying -stable storage hardware. For example, consider a SCSI controller that -has been configured to cache data and return to the operating system that -the data has been written to stable storage, when, in fact, it has only -been written into the controller RAM cache. If power is lost before the -controller is able to flush its cache to disk, and the controller cache -is not stable (i.e., the writes will not be flushed to disk when power -returns), the writes will be lost. If the writes include database blocks, -there is no loss as recovery will correctly update the database. If the -writes include log file blocks, it is possible that transactions that were -already committed may not appear in the recovered database, although the -recovered database will be coherent after a crash. -<p>If the underlying hardware can fail in any way such that only part of the -block was written, the failure conditions are the same as those described -above for an operating system failure that only writes part of a logical -database block. -<p>For these reasons, it is important to select hardware that does not do -partial writes and does not cache data writes (or does not return that -the data has been written to stable storage until it either has been -written to stable storage or the actual writing of all of the data is -guaranteed barring catastrophic hardware failure, e.g., your disk drive -exploding). You should also be aware that Berkeley DB does not protect against -all cases of stable storage hardware failure, nor does it protect against -hardware misbehavior. -<p>If the disk drive on which you are storing your databases explodes, you -can perform normal Berkeley DB catastrophic recovery, as that requires only a -snapshot of your databases plus all of the log files you have archived -since those snapshots were taken. In this case, you will lose no database -changes at all. If the disk drive on which you are storing your log files -explodes, you can still perform catastrophic recovery, but you will lose -any database changes that were part of transactions committed since your -last archival of the log files. For this reason, storing your databases -and log files on different disks should be considered a safety measure as -well as a performance enhancement. -<p>Finally, if your hardware misbehaves, for example, a SCSI controller -writes incorrect data to the disk, Berkeley DB will not detect this and your -data may be corrupted. -<table><tr><td><br></td><td width="1%"><a href="../../ref/transapp/filesys.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../../ref/toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../../ref/transapp/throughput.html"><img src="../../images/next.gif" alt="Next"></a> -</td></tr></table> -<p><font size=1><a href="http://www.sleepycat.com">Copyright Sleepycat Software</a></font> -</body> -</html> diff --git a/bdb/docs/ref/transapp/recovery.html b/bdb/docs/ref/transapp/recovery.html deleted file mode 100644 index 5be94bf417c..00000000000 --- a/bdb/docs/ref/transapp/recovery.html +++ /dev/null @@ -1,91 +0,0 @@ -<!--$Id: recovery.so,v 10.26 2000/08/16 17:50:40 margo Exp $--> -<!--Copyright 1997, 1998, 1999, 2000 by Sleepycat Software, Inc.--> -<!--All rights reserved.--> -<html> -<head> -<title>Berkeley DB Reference Guide: Recovery procedures</title> -<meta name="description" content="Berkeley DB: An embedded database programmatic toolkit."> -<meta name="keywords" content="embedded,database,programmatic,toolkit,b+tree,btree,hash,hashing,transaction,transactions,locking,logging,access method,access methods,java,C,C++"> -</head> -<body bgcolor=white> - <a name="2"><!--meow--></a> -<table><tr valign=top> -<td><h3><dl><dt>Berkeley DB Reference Guide:<dd>Transaction Protected Applications</dl></h3></td> -<td width="1%"><a href="../../ref/transapp/logfile.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../../ref/toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../../ref/transapp/filesys.html"><img src="../../images/next.gif" alt="Next"></a> -</td></tr></table> -<p> -<h1 align=center>Recovery procedures</h1> -<p>The fifth component of the infrastructure, recovery procedures, concerns -the recoverability of the database.

The two -gating factors for Berkeley DB performance in a transactional system are usually -the underlying database files and the log file. Both are factors because -they require disk I/O, which is slow relative to other system resources -like CPU. -<p>In the worst case scenario: -<ul type=disc> -<li>Database access is truly random and the database is too large to fit into -the cache, resulting in a single I/O per requested key/data pair. -<li>Both the database and the log are on a single disk. -</ul> -<p>This means that for each transaction, Berkeley DB is potentially performing -several filesystem operations: -<ul type=disc> -<li>Disk seek to database file. -<li>Database file read. -<li>Disk seek to log file. -<li>Log file write. -<li>Flush log file information to disk. -<li>Disk seek to update log file metadata (e.g., inode). -<li>Log metadata write. -<li>Flush log file metadata to disk. -</ul> -<p>There are a number of ways to increase transactional throughput, all of -which attempt to decrease the number of filesystem operations per -transaction: -<ul type=disc> -<li>Tune the size of the database cache. If the Berkeley DB key/data pairs used -during the transaction are found in the database cache, the seek and read -from the database are no longer necessary, resulting in two fewer -filesystem operations per transaction. To determine if your cache size -is too small, see <a href="../../ref/am_conf/cachesize.html">Selecting a -cache size</a>. -<li>Put the database and the log files on different disks. This allows reads -and writes to the log files and the database files to be performed -concurrently. -<li>Set the filesystem configuration so that file access and modification -times are not updated. Note, although the file access and modification -times are not used by Berkeley DB, this may affect other programs, so be -careful. -<li>Upgrade your hardware. When considering the hardware on which to run your -application, however, it is important to consider the entire system. The -controller and bus can have as much to do with the disk performance as -the disk itself. It is also important to remember that throughput is -rarely the limiting factor, and that disk seek times are normally the true -performance issue for Berkeley DB. -<li>Turn on the <a href="../../api_c/env_open.html#DB_TXN_NOSYNC">DB_TXN_NOSYNC</a> flag. This changes the Berkeley DB behavior -so that the log files are not flushed when transactions are committed. -While this change will greatly increase your transaction throughput, it -means that transactions will exhibit the ACI (atomicity, consistency and -isolation) properties, but not D (durability). Database integrity will -be maintained but it is possible that some number of the most recently -committed transactions may be undone during recovery instead of being -redone. -</ul> -<p>If you are bottlenecked on logging, the following test will help you -confirm that the number of transactions per second that your application -does is reasonable for the hardware on which you're running. Your test -program should repeatedly perform the following operations: -<ul type=disc> -<li>Seek to the beginning of a file. -<li>Write to the file. -<li>Flush the file write to disk. -</ul> -<p>The number of times that you can perform these three operations per second -is a rough measure of the number of transactions per second of which the -hardware is capable. This test simulates the operations applied to the -log file. (As a simplifying assumption in this experiment, we assume that -the database files are either on a separate disk, or that they fit, with -some few exceptions, into the database cache.) We do not have to directly -simulate updating the log file directory information, as it will normally -be updated and flushed to disk as a result of flushing the log file write -to disk. -<p>Running this test program, where we write 256 bytes, for 1000 operations, -on reasonably standard commodity hardware (Pentium II CPU, SCSI disk), -returned the following results: -<p><blockquote><pre>% testfile -b256 -o1000 -running: 1000 ops -Elapsed time: 16.641934 seconds -1000 ops: 60.09 ops per second</pre></blockquote> -<p>Note that the number of bytes being written to the log as part of each -transaction can dramatically affect the transaction throughput. The -above test run used 256, which is a reasonable size log write. Your -log writes may be different. To determine your average log write size, -use the <a href="../../utility/db_stat.html">db_stat</a> utility to display your log statistics. -<p>As a quick sanity check, for this particular disk, the average seek time -is 9.4 msec, and the average latency is 4.17 msec. That results in a -minimum requirement for a data transfer to the disk of 13.57 msec, or a -maximum of 74 transfers per second. This is close enough to the above 60 -operations per second (which wasn't done on a quiescent disk) that the -number is believable. -<p>An implementation of the above <a href="writetest.txt">example test -program</a> for IEEE/ANSI Std 1003.1 (POSIX) standard systems is included in the Berkeley DB -distribution. -<table><tr><td><br></td><td width="1%"><a href="../../ref/transapp/reclimit.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../../ref/toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../../ref/xa/intro.html"><img src="../../images/next.gif" alt="Next"></a> -</td></tr></table> -<p><font size=1><a href="http://www.sleepycat.com">Copyright Sleepycat Software</a></font> -</body> -</html> diff --git a/bdb/docs/ref/transapp/transapp.txt b/bdb/docs/ref/transapp/transapp.txt deleted file mode 100644 index afd441c59f8..00000000000 --- a/bdb/docs/ref/transapp/transapp.txt +++ /dev/null @@ -1,492 +0,0 @@ -#include <sys/types.h> -#include <sys/stat.h> - -#include <errno.h> -#include <pthread.h> -#include <stdarg.h> -#include <stdlib.h> -#include <string.h> -#include <unistd.h> - -#include <db.h> - -#define ENV_DIRECTORY "TXNAPP" - -void add_cat(DB_ENV *, DB *, char *, ...); -void add_color(DB_ENV *, DB *, char *, int); -void add_fruit(DB_ENV *, DB *, char *, char *); -void *checkpoint_thread(void *); -void log_archlist(DB_ENV *); -void *logfile_thread(void *); -void db_open(DB_ENV *, DB **, char *, int); -void env_dir_create(void); -void env_open(DB_ENV **); -void usage(void); - -int -main(int argc, char *argv[]) -{ - extern char *optarg; - extern int optind; - DB *db_cats, *db_color, *db_fruit; - DB_ENV *dbenv; - pthread_t ptid; - int ch; - - while ((ch = getopt(argc, argv, "")) != EOF) - switch (ch) { - case '?': - default: - usage(); - } - argc -= optind; - argv += optind; - - env_dir_create(); - env_open(&dbenv); - - /* Start a checkpoint thread. */ - if ((errno = pthread_create( - &ptid, NULL, checkpoint_thread, (void *)dbenv)) != 0) { - fprintf(stderr, - "txnapp: failed spawning checkpoint thread: %s\n", - strerror(errno)); - exit (1); - } - - /* Start a logfile removal thread. */ - if ((errno = pthread_create( - &ptid, NULL, logfile_thread, (void *)dbenv)) != 0) { - fprintf(stderr, - "txnapp: failed spawning log file removal thread: %s\n", - strerror(errno)); - exit (1); - } - - /* Open database: Key is fruit class; Data is specific type. */ - db_open(dbenv, &db_fruit, "fruit", 0); - - /* Open database: Key is a color; Data is an integer. */ - db_open(dbenv, &db_color, "color", 0); - - /* - * Open database: - * Key is a name; Data is: company name, address, cat breeds. - */ - db_open(dbenv, &db_cats, "cats", 1); - - add_fruit(dbenv, db_fruit, "apple", "yellow delicious"); - - add_color(dbenv, db_color, "blue", 0); - add_color(dbenv, db_color, "blue", 3); - - add_cat(dbenv, db_cats, - "Amy Adams", - "Sleepycat Software", - "394 E.

Instead there is only the -DB_ENV structure. This means that DB_ENV references should -be passed around by your application instead of passing around DB_LOCKTAB -or DB_TXNMGR references. This is likely to be a simple change for most -applications as few applications use the lock_XXX, log_XXX, -memp_XXX or txn_XXX interfaces to create Berkeley DB environments. -<p>The second change is that there are no longer separate open, close, and -unlink interfaces to the -Berkeley DB subsystems, e.g., in previous releases, it was possible to open a -lock subsystem either using db_appinit or using the lock_open call. In -the 3.0 release the XXX_open interfaces to the subsystems have been -removed, and subsystems must now be opened using the 3.0 replacement for the -db_appinit call. -<p>To upgrade your application, first find each place your application opens, -closes and/or removes a Berkeley DB environment. This will be code of the form: -<p><blockquote><pre>db_appinit, db_appexit -lock_open, lock_close, lock_unlink -log_open, log_close, log_unlink -memp_open, memp_close, memp_unlink -txn_open, txn_close, txn_unlink</pre></blockquote> -<p>Each of these groups of calls should be replaced with calls to: -<p><blockquote><pre><a href="../../api_c/env_create.html">db_env_create</a>, <a href="../../api_c/env_open.html">DBENV->open</a>, <a href="../../api_c/env_close.html">DBENV->close</a>, -<a href="../../api_c/env_remove.html">DBENV->remove</a></pre></blockquote> -<p>The <a href="../../api_c/env_create.html">db_env_create</a> call and the call to the <a href="../../api_c/env_open.html">DBENV->open</a> -method replace the db_appinit, lock_open, log_open, memp_open and txn_open -calls. The <a href="../../api_c/env_close.html">DBENV->close</a> method replaces the db_appexit, -lock_close, log_close, memp_close and txn_close calls. The -<a href="../../api_c/env_remove.html">DBENV->remove</a> call replaces the lock_unlink, log_unlink, -memp_unlink and txn_unlink calls. -<p>Here's an example creating a Berkeley DB environment using the 2.X interface: -<p><blockquote><pre>/* - * db_init -- - * Initialize the environment. - */ -DB_ENV * -db_init(home) - char *home; -{ - DB_ENV *dbenv; -<p> - if ((dbenv = (DB_ENV *)calloc(sizeof(DB_ENV), 1)) == NULL) - return (errno); -<p> - if ((errno = db_appinit(home, NULL, dbenv, - DB_INIT_LOCK | DB_INIT_LOG | DB_INIT_MPOOL | DB_INIT_TXN | - DB_USE_ENVIRON)) == 0) - return (dbenv); -<p> - free(dbenv); - return (NULL); -}</pre></blockquote> -<p>In the Berkeley DB 3.0 release, this code would be written as: -<p><blockquote><pre>/* - * db_init -- - * Initialize the environment. - */ -int -db_init(home, dbenvp) - char *home; - DB_ENV **dbenvp; -{ - int ret; - DB_ENV *dbenv; -<p> - if ((ret = db_env_create(&dbenv, 0)) != 0) - return (ret); -<p> - if ((ret = dbenv->open(dbenv, home, NULL, - DB_INIT_LOCK | DB_INIT_LOG | DB_INIT_MPOOL | DB_INIT_TXN | - DB_USE_ENVIRON, 0)) == 0) { - *dbenvp = dbenv; - return (0); - } -<p> - (void)dbenv->close(dbenv, 0); - return (ret); -}</pre></blockquote> -<p>As you can see, the arguments to db_appinit and to <a href="../../api_c/env_open.html">DBENV->open</a> are -largely the same. There is some minor re-organization: the mapping is -that arguments #1, 2, 3, and 4 to db_appinit become arguments #2, 3, 1 -and 4 to <a href="../../api_c/env_open.html">DBENV->open</a>. There is one additional argument to -<a href="../../api_c/env_open.html">DBENV->open</a>, argument #5. For backward compatibility with the 2.X -Berkeley DB releases, simply set that argument to 0. -<p>It is only slightly more complex to translate calls to XXX_open to the -<a href="../../api_c/env_open.html">DBENV->open</a> method.

If your -application is using this flag, it should almost certainly use the new -<a href="../../api_c/env_open.html#DB_PRIVATE">DB_PRIVATE</a> flag to the <a href="../../api_c/env_open.html">DBENV->open</a> interface. Regardless, -you should carefully consider this change before converting to use the -<a href="../../api_c/env_open.html#DB_PRIVATE">DB_PRIVATE</a> flag. -<p>Translating db_appexit or XXX_close calls to <a href="../../api_c/env_close.html">DBENV->close</a> is equally -simple. Instead of taking a reference to a per-subsystem structure such -as DB_LOCKTAB or DB_TXNMGR, all calls take a reference to a DB_ENV -structure. The calling sequence is otherwise unchanged. Note that as -the application no longer allocates the memory for the DB_ENV structure, -application code to discard it after the call to db_appexit() is no longer -needed. -<p>Translating XXX_unlink calls to <a href="../../api_c/env_remove.html">DBENV->remove</a> is slightly more complex. -As with <a href="../../api_c/env_close.html">DBENV->close</a>, the call takes a reference to a DB_ENV -structure instead of a per-subsystem structure. The calling sequence is -slightly different, however. Here is an example of removing a lock region -using the 2.X interface: -<p><blockquote><pre>DB_ENV *dbenv; -<p> -ret = lock_unlink(dir, 1, dbenv);</pre></blockquote> -<p>In the Berkeley DB 3.0 release, this code fragment would be written as: -<p><blockquote><pre>DB_ENV *dbenv; -<p> -ret = dbenv->remove(dbenv, dir, NULL, DB_FORCE);</pre></blockquote> -<p>The additional argument to the <a href="../../api_c/env_remove.html">DBENV->remove</a> function is a -configuration argument similar to that previously taken by db_appinit and -now taken by the <a href="../../api_c/env_open.html">DBENV->open</a> method. For backward compatibility -this new argument should simply be set to NULL.

-<p>To upgrade your application, first find each place your application opens -a database, that is, calls the db_open function. Each of these calls -should be replaced with calls to <a href="../../api_c/db_create.html">db_create</a> and <a href="../../api_c/db_open.html">DB->open</a>. -<p>Here's an example creating a Berkeley DB database using the 2.X interface: -<p><blockquote><pre>DB *dbp; -DB_ENV *dbenv; -int ret; -<p> -if ((ret = db_open(DATABASE, - DB_BTREE, DB_CREATE, 0664, dbenv, NULL, &dbp)) != 0) - return (ret);</pre></blockquote> -<p>In the Berkeley DB 3.0 release, this code would be written as: -<p><blockquote><pre>DB *dbp; -DB_ENV *dbenv; -int ret; -<p> -if ((ret = db_create(&dbp, dbenv, 0)) != 0) - return (ret); -<p> -if ((ret = dbp->open(dbp, - DATABASE, NULL, DB_BTREE, DB_CREATE, 0664)) != 0) { - (void)dbp->close(dbp, 0); - return (ret); -}</pre></blockquote> -<p>As you can see, the arguments to db_open and to <a href="../../api_c/db_open.html">DB->open</a> are -largely the same. There is some re-organization, and note that the -enclosing DB_ENV structure is specified when the DB object -is created using the <a href="../../api_c/db_create.html">db_create</a> interface. There is one -additional argument to <a href="../../api_c/db_open.html">DB->open</a>, argument #3. For backward -compatibility with the 2.X Berkeley DB releases, simply set that argument to -NULL. -<p>There are two additional issues with the db_open call. -<p>First, it was possible in the 2.X releases for an application to provide -an environment that did not contain a shared memory buffer pool as the -database environment, and Berkeley DB would create a private one automatically. -This functionality is no longer available, applications must specify the -<a href="../../api_c/env_open.html#DB_INIT_MPOOL">DB_INIT_MPOOL</a> flag if databases are going to be opened in the -environment. -<p>The final issue with upgrading the db_open call is that the DB_INFO -structure is no longer used, having been replaced by individual methods -on the DB handle. That change is discussed in detail later in -this chapter. -<table><tr><td><br></td><td width="1%"><a href="../../ref/upgrade.3.0/dbenv.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../../ref/toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../../ref/upgrade.3.0/xa.html"><img src="../../images/next.gif" alt="Next"></a> -</td></tr></table> -<p><font size=1><a href="http://www.sleepycat.com">Copyright Sleepycat Software</a></font> -</body> -</html> diff --git a/bdb/docs/ref/upgrade.3.0/rmw.html b/bdb/docs/ref/upgrade.3.0/rmw.html deleted file mode 100644 index a1a30da5ecf..00000000000 --- a/bdb/docs/ref/upgrade.3.0/rmw.html +++ /dev/null @@ -1,31 +0,0 @@ -<!--$Id: rmw.so,v 11.9 2000/03/18 21:43:21 bostic Exp $--> -<!--Copyright 1997, 1998, 1999, 2000 by Sleepycat Software, Inc.--> -<!--All rights reserved.--> -<html> -<head> -<title>Berkeley DB Reference Guide: Release 3.0: DB_RMW</title> -<meta name="description" content="Berkeley DB: An embedded database programmatic toolkit."> -<meta name="keywords" content="embedded,database,programmatic,toolkit,b+tree,btree,hash,hashing,transaction,transactions,locking,logging,access method,access methods,java,C,C++"> -</head> -<body bgcolor=white> -<table><tr valign=top> -<td><h3><dl><dt>Berkeley DB Reference Guide:<dd>Upgrading Berkeley DB Applications</dl></h3></td> -<td width="1%"><a href="../../ref/upgrade.3.0/txn_stat.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../../ref/toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../../ref/upgrade.3.0/lock_notheld.html"><img src="../../images/next.gif" alt="Next"></a> -</td></tr></table> -<p> -<h1 align=center>Release 3.0: DB_RMW</h1> -<p>The following change applies only to applications using the -Berkeley DB Concurrent Data Store product.

To do this, use the -Tuxedo <b>buildtms</b>(1) utility. The buildtms utility will create -the Berkeley-DB resource manager in the directory from which it was run. -The parameters to buildtms should be: -<p><blockquote><pre>buildtms -v -o DBRM -r BERKELEY-DB</pre></blockquote> -<p>This will create an executable transaction manager server, DBRM, that is -called by Tuxedo to process begins, commits, and aborts. -<p>Finally, you must make sure that your TUXCONFIG environment variable -identifies a ubbconfig file that properly identifies your resource -managers. In the GROUPS section of the ubb file, you should identify the -group's LMID and GRPNO as well as the transaction manager server name -"TMSNAME=DBRM." You must also specify the OPENINFO parameter, setting it -equal to the string: -<p><blockquote><pre>rm_name:dir</pre></blockquote> -<p>where rm_name is the resource name specified in the RM file (i.e., -BERKELEY-DB) and dir is the directory for the Berkeley DB home environment -(see <a href="../../api_c/env_open.html">DBENV->open</a> for a discussion of Berkeley DB environments). -<p>As Tuxedo resource manager startup accepts only a single string for -configuration, any environment customization that might have been done -via the config parameter to <a href="../../api_c/env_open.html">DBENV->open</a> must instead be done by -placing a <a href="../../ref/env/naming.html#DB_CONFIG">DB_CONFIG</a> file in the Berkeley DB environment directory. See -<a href="../../ref/env/naming.html">Berkeley DB File Naming</a> for further -information. -<p>Consider the following configuration.
