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.
