+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.
+
