<p>
Configures the total number of mutexes to allocate. Berkeley DB
allocates a default number of mutexes based on the initial
configuration of the database environment. That default calculation
may be too small if the application has an unusual need for
mutexes. This parameter is used to specify an absolute number of
mutexes to allocate.
</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_max</code>, one or more
whitespace characters, and the total number of mutexes. Because
the DB_CONFIG file is read when the database environment is
opened, it will silently overrule configuration done before that
time.
