+Feature: no locking
+*******************
+
+.. contents::
+    :depth: 3
+
+The no-locking feature allows applications to use a Lock Manager that always succeeds.  It does not deny
+acquiring resource locks.
+
+To utilize the no-locking feature, first stop policy engine, disable other locking features, and then enable it
+using the "*features*" command.
+
+In an official OOM installation, place a script with a .pre.sh suffix:
+
+    .. code-block:: bash
+       :caption: features.pre.sh
+        #!/bin/sh
+
+        sh -c "features disable distributed-locking"
+        sh -c "features enable no-locking"
+
+
+under the directory:
+
+    .. code-block:: bash
+        oom/kubernetes/policy/components/policy-drools-pdp/resources/configmaps
+
+
+and rebuild the policy charts.
+
+At container initialization, the distributed-locking will be disabled, and the no-locking feature will be enabled.
