The environment home -directory must be created before any Berkeley DB applications are run. Berkeley DB -itself never creates the environment home directory. The environment can -then be identified by the name of that directory. -<p>An environment may be shared by any number of applications as well as by -any number of threads within the applications. It is possible for an -environment to include resources from other directories on the system, -and applications often choose to distribute resources to other directories -or disks for performance or other reasons. However, by default, the -databases, shared regions (the locking, logging, memory pool, and -transaction shared memory areas) and log files will be stored in a single -directory hierarchy. -<p>It is important to realize that all applications sharing a database -environment implicitly trust each other. They have access to each other's -data as it resides in the shared regions and they will share resources -such as buffer space and locks. At the same time, any applications using -the same databases <b>must</b> share an environment if consistency is -to be maintained between them. -<p>The Berkeley DB environment is created and described by the <a href="../../api_c/env_create.html">db_env_create</a> -and <a href="../../api_c/env_open.html">DBENV->open</a> interfaces. In situations where customization is -desired, such as storing log files on a separate disk drive, applications -must describe the customization by either creating an environment -configuration file in the environment home directory or by arguments -passed to the <a href="../../api_c/env_open.html">DBENV->open</a> interface. See the documentation on that -function for details on this procedure. -<p>Once an environment has been created, database files specified using -relative pathnames will be named relative to the home directory. Using -pathnames relative to the home directory allows the entire environment -to be easily moved to facilitate restoring and recovering a database in -a different directory or on a different system. -<table><tr><td><br></td><td width="1%"><a href="../../ref/arch/utilities.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/env/create.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> |
