ThreadCount must set if <a href="M_BerkeleyDB_DatabaseEnvironment_FailCheck.htm">FailCheck<span class="languageSpecificText"><span class="cs">()</span><span class="cpp">()</span><span class="nu">()</span></span></a>
will be used. ThreadCount does not set the maximum number of threads
but is used to determine memory sizing and the thread control block
reclamation policy.
</p>
<p>
If a process has not configured <a href="F_BerkeleyDB_DatabaseEnvironmentConfig_ThreadIsAlive.htm">ThreadIsAlive</a>, and
then attempts to join a database environment configured for failure
checking with <a href="M_BerkeleyDB_DatabaseEnvironment_FailCheck.htm">FailCheck<span class="languageSpecificText"><span class="cs">()</span><span class="cpp">()</span><span class="nu">()</span></span></a>,
<a href="F_BerkeleyDB_DatabaseEnvironmentConfig_SetThreadID.htm">SetThreadID</a>, <a href="F_BerkeleyDB_DatabaseEnvironmentConfig_ThreadIsAlive.htm">ThreadIsAlive</a> and
ThreadCount, the program may be unable to allocate a thread control
block and fail to join the environment. This is true of the
standalone Berkeley DB utility programs. To avoid problems when
using the standalone Berkeley DB utility programs with environments
configured for failure checking, incorporate the utility's
functionality directly in the application, or call
<a href="M_BerkeleyDB_DatabaseEnvironment_FailCheck.htm">FailCheck<span class="languageSpecificText"><span class="cs">()</span><span class="cpp">()</span><span class="nu">()</span></span></a> before running the
utility.
