However, the supplied utilities can be generally useful tools even when the application is responsible for doing its own administration because applications rarely offer external interfaces to database administration. The utilities are required when programming to a Berkeley DB scripting interface because the scripting APIs do not always offer interfaces to the administrative functionality.</p> </div> <div class="navfooter"> <hr /> <table width="100%" summary="Navigation footer"> <tr> <td width="40%" align="left"><a accesskey="p" href="transapp_nested.html">Prev</a>Β </td> <td width="20%" align="center"> <a accesskey="u" href="transapp.html">Up</a> </td> <td width="40%" align="right">Β <a accesskey="n" href="transapp_deadlock.html">Next</a></td> </tr> <tr> <td width="40%" align="left" valign="top">Nested transactionsΒ </td> <td width="20%" align="center"> <a accesskey="h" href="index.html">Home</a> </td> <td width="40%" align="right" valign="top">Β Deadlock detection</td> </tr> </table> </div> </body> </html>
