+Feature: Distributed Locking
+****************************
+
+Summary
+^^^^^^^
+
+The Distributed Locking Feature provides locking of resources across a pool of PDP-D hosts. The list of locks is maintained in a database, where each record includes a resource identifier, an owner identifier, and an expiration time. Typically, a drools application will unlock the resource when it's operation completes. However, if it fails to do so, then the resource will be automatically released when the lock expires, thus preventing a resource from becoming permanently locked.
+
+Usage
+^^^^^
+
+ .. code-block:: bash
+ :caption: Enable Feature Distributed Locking
+
+ policy stop
+
+ features enable distributed-locking
+
+ The configuration is located at:
+
+ * $POLICY_HOME/config/feature-distributed-locking.properties
+
+
+ .. code-block:: bash
+ :caption: Start the PDP-D using pooling
+
+ policy start
+
+
+ .. code-block:: bash
+ :caption: Disable the Distributed Locking feature
+
+ policy stop
+ features disable distributed-locking
+ policy start
