Other problems, such as potentially fatal errors in Berkeley DB, will be ignored as well. This option is intended only for debugging errors, and should not be used under any other circumstances. <p><dt><b>-r</b><dd>Read the log files in reverse order. <p><dt><b>-V</b><dd>Write the library version number to the standard output, and exit. </dl> <p>For more information on the db_printlog output and using it to debug applications, see <a href="../../db4-devel-4.0.14/ref/debug/printlog.html">Reviewing Berkeley DB log files</a>. <p>The db_printlog utility uses a Berkeley DB environment (as described for the <b>-h</b> option, the environment variable <b>DB_HOME</b>, or because the utility was run in a directory containing a Berkeley DB environment). In order to avoid environment corruption when using a Berkeley DB environment, db_printlog should always be given the chance to detach from the environment and exit gracefully. To cause db_printlog to release all environment resources and exit cleanly, send it an interrupt signal (SIGINT). <p>The db_printlog utility exits 0 on success, and >0 if an error occurs. <h1>Environment Variables</h1> <p><dl compact> <p><dt>DB_HOME<dd>If the <b>-h</b> option is not specified and the environment variable DB_HOME is set, it is used as the path of the database home, as described in <a href="../../db4-devel-4.0.14/api_c/env_open.html">DB_ENV->open</a>. </dl> <h1>See Also</h1> <a href="../../db4-4.0.14/utility/berkeley_db_svc.html">berkeley_db_svc</a>, <a href="../../db4-4.0.14/utility/db_archive.html">db_archive</a>, <a href="../../db4-4.0.14/utility/db_checkpoint.html">db_checkpoint</a>, <a href="../../db4-4.0.14/utility/db_deadlock.html">db_deadlock</a>, <a href="../../db4-4.0.14/utility/db_dump.html">db_dump</a>, <a href="../../db4-4.0.14/utility/db_load.html">db_load</a>, <a href="../../db4-4.0.14/utility/db_recover.html">db_recover</a>, <a href="../../db4-4.0.14/utility/db_stat.html">db_stat</a>, <a href="../../db4-4.0.14/utility/db_upgrade.html">db_upgrade</a>, and <a href="../../db4-4.0.14/utility/db_verify.html">db_verify</a>. </tt> <p><font size=1><a href="http://www.sleepycat.com">Copyright Sleepycat Software</a></font> </body> </html>
