/*! @page processes Sharing Between Processes

@notyet{inter-process sharing}

WiredTiger includes a server that provides remote access to databases.  The primary process to open a database can optionally start a server that handles requests from other processes.

The remote interface is the way languages other than C/C++ are supported, and the interface for client processes in multiprocess C/C++ applications.

The server can be embedded in an application or run from the command line.  To embed the RPC server in your application, pass <code>"multiprocess"</code> in the configuration string to ::wiredtiger_open.  Note that in this case, when your application exits, all client connections are forcibly closed.

For details on running a standalone RPC server, see @ref utility.

@section processes_sharing Opening connections from multiple processes

When ::wiredtiger_open is called for a database, one of the following occurs:

# no process has the database open, it was closed cleanly.  In this case, the opening process becomes the primary process and the database is opened without recovery.
# no process has the database open, but it was not closed cleanly.  In this case, the process becomes the primary and recovery is run before the database is opened.  See @ref transaction_recovery for details.
# another process has the database open and is running the RPC server, in which case the opening process becomes a client.
# another process has the database open but is not running the RPC server, in which case the open fails.
