<p>
Sets the size of the underlying logging area of the Berkeley DB
environment, in bytes. By default, or if the value is set to 0, the
minimum region size is used, approximately 128KB. The log region is
used to store filenames, and so may need to be increased in size if a
large number of files will be opened and registered with the specified
Berkeley DB environment's log manager.
</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">set_lg_regionmax</code>, one or more
whitespace characters, and the log region size in bytes.
</p>
<p>
If the database environment already exists when this parameter is
changed, it is ignored. To change this value after the environment
has been created, re-create your environment.
</p>
