<h1>Description</h1>
<p><b>The DbEnv.set_lk_max method interface has been deprecated in favor of
the <a href="../api_java/env_set_lk_max_locks.html">DbEnv.set_lk_max_locks</a>, <a href="../api_java/env_set_lk_max_lockers.html">DbEnv.set_lk_max_lockers</a>,
and <a href="../api_java/env_set_lk_max_objects.html">DbEnv.set_lk_max_objects</a> methods. 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_java/env_open.html">DbEnv.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.set_lk_max interface may only be used to configure Berkeley DB before
the <a href="../api_java/env_open.html">DbEnv.open</a> interface is called.
<p>The DbEnv.set_lk_max method throws an exception that encapsulates a non-zero error value on
failure.
<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>
