<h1>Description</h1>
<p>The <a href="../../db4-devel-4.0.14/api_java/dbenv_class.html">DbEnv</a> lock methods and the DbLock class are used to
provide general-purpose locking. Although designed to work with the
other Db classes, they are also useful for more general locking
purposes. Locks can be shared between processes.
<p>In most cases, when multiple threads or processes are using locking, the
deadlock detector, <a href="../../db4-4.0.14/utility/db_deadlock.html">db_deadlock</a> should be run.
