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 + + +End of Document + +..
