Configures the number of additional mutexes to allocate. If an
application will allocate mutexes for its own use, this parameter
is used to add a number of mutexes to the default allocation.
</p>
<p>
The syntax of this parameter in the <a href="../../programmer_reference/env_db_config.html#env_db_config.DB_CONFIG" class="olink">DB_CONFIG</a> file is a single
line with the string <code class="literal">mutex_set_increment</code>, one
or more whitespace characters, and the number of additional
mutexes. Because the DB_CONFIG file is read when the database
environment is opened, it will silently overrule configuration
done before that time.
