This will create Berkeley DB with debugging symbols, as well as load various Berkeley DB routines that can be called directly from a debugger to display database page content, cursor queues, and so forth.

This will cause a number of special checks to be performed when Berkeley DB is running. This flag should not be defined when configuring to build production binaries because it degrades performance.</ul> <b><a href="../../ref/build_unix/conf.html#--enable-umrw">--enable-umrw</a></b><ul compact><li>When compiling Berkeley DB for use in run-time memory consistency checkers (in particular, programs that look for reads and writes of uninitialized memory), use --enable-umrw as an argument to configure. This guarantees, among other things, that Berkeley DB will completely initialize allocated pages rather than initializing only the minimum necessary amount.</ul> <br> <table width="100%"><tr><td><br></td><td align=right><a href="../debug/intro.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../debug/runtime.html"><img src="../../images/next.gif" alt="Next"></a> </td></tr></table> <p><font size=1>Copyright (c) 1996,2008 Oracle.
