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>
|
||
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.
