It facilitates log reclamation and the creation of database snapshots. Generally, some form of log archival must be done if a database environment has been configured for logging or transactions.</ul> <b><a href="../../utility/db_checkpoint.html">db_checkpoint</a></b><ul compact><li>The <a href="../../utility/db_checkpoint.html">db_checkpoint</a> utility runs as a daemon process, monitoring the database log and periodically issuing checkpoints. It facilitates log reclamation and the creation of database snapshots. Generally, some form of database checkpointing must be done if a database environment has been configured for transactions.</ul> <b><a href="../../utility/db_deadlock.html">db_deadlock</a></b><ul compact><li>The <a href="../../utility/db_deadlock.html">db_deadlock</a> utility runs as a daemon process, periodically traversing the database lock structures and aborting transactions when it detects a deadlock. Generally, some form of deadlock detection must be done if a database environment has been configured for locking.</ul> <b><a href="../../utility/db_dump.html">db_dump</a></b><ul compact><li>The <a href="../../utility/db_dump.html">db_dump</a> utility writes a copy of the database to a flat-text file in a portable format.</ul> <b><a href="../../utility/db_load.html">db_load</a></b><ul compact><li>The <a href="../../utility/db_load.html">db_load</a> utility reads the flat-text file produced by <a href="../../utility/db_dump.html">db_dump</a> and loads it into a database file.</ul> <b><a href="../../utility/db_printlog.html">db_printlog</a></b><ul compact><li>The <a href="../../utility/db_printlog.html">db_printlog</a> utility displays the contents of Berkeley DB log files in a human-readable and parsable format.</ul> <b><a href="../../utility/db_recover.html">db_recover</a></b><ul compact><li>The <a href="../../utility/db_recover.html">db_recover</a> utility runs after an unexpected Berkeley DB or system failure to restore the database to a consistent state. Generally, some form of database recovery must be done if databases are being modified.</ul> <b><a href="../../utility/db_stat.html">db_stat</a> </b><ul compact><li>The <a href="../../utility/db_stat.html">db_stat</a> utility displays statistics for databases and database environments.</ul> <b><a href="../../utility/db_upgrade.html">db_upgrade</a></b><ul compact><li>The <a href="../../utility/db_upgrade.html">db_upgrade</a> utility provides a command-line interface for upgrading underlying database formats.</ul> <b><a href="../../utility/db_verify.html">db_verify</a></b><ul compact><li>The <a href="../../utility/db_verify.html">db_verify</a> utility provides a command-line interface for verifying the database format.</ul> <br> <p>All of the functionality implemented for these utilities is also available as part of the standard Berkeley DB API. This means that threaded applications can easily create a thread that calls the same Berkeley DB functions as do the utilities. This often simplifies an application environment by removing the necessity for multiple processes to negotiate database and database environment creation and shut down.</p> <table width="100%"><tr><td><br></td><td align=right><a href="../arch/script.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../env/intro.html"><img src="../../images/next.gif" alt="Next"></a> </td></tr></table> <p><font size=1>Copyright (c) 1996,2008 Oracle.
