<p>
Sets the maximum number of locking entities supported by the Berkeley DB
environment. This value is used by Berkeley DB to estimate how much
space to allocate for various lock-table data structures.
When using the DB, the default value is 1,000 lockers.
When using the BDB SQL interface, the default value is 2,000 lockers.
</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_lk_max_lockers</code>, one or more
whitespace characters, and the number of lockers.
</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.
