<h1>Description</h1>
<p><b>The DBENV-&gt;set_lk_max function interface has been deprecated in favor of
the <a href="../api_c/env_set_lk_max_locks.html">DBENV-&gt;set_lk_max_locks</a>, <a href="../api_c/env_set_lk_max_lockers.html">DBENV-&gt;set_lk_max_lockers</a>,
and <a href="../api_c/env_set_lk_max_objects.html">DBENV-&gt;set_lk_max_objects</a> functions.  Please update your applications.</b>
<p>Set each of the maximum number of locks, lockers and lock objects
supported by the Berkeley DB lock subsystem to <b>max</b>.  This value is
used by <a href="../api_c/env_open.html">DBENV-&gt;open</a> to estimate how much space to allocate for
various lock-table data structures.  For specific information on
configuring the size of the lock subsystem, see
<a href="../ref/lock/max.html">Configuring locking:  sizing the
system</a>.
<p>The DBENV-&gt;set_lk_max interface may only be used to configure Berkeley DB before
the <a href="../api_c/env_open.html">DBENV-&gt;open</a> interface is called.
<p>The DBENV-&gt;set_lk_max function returns a non-zero error value on failure and 0 on success.
<p>The database environment's maximum number of locks may also be set using the environment's
<b>DB_CONFIG</b> file.  The syntax of the entry in that file is a
single line with the string "set_lk_max", one or more whitespace characters,
and the number of locks.  Because the <b>DB_CONFIG</b> file is read when the database
environment is opened, it will silently overrule configuration done
before that time.
<h1>Errors</h1>
