The enqueue domain supports the CICS® recovery manager. Enqueue statistics contain the global data collected by the enqueue domain for enqueue requests.
Waiting for an enqueue on a resource can add significant delays in the execution of a transaction. The enqueue statistics allow you to assess the impact of waiting for enqueues in the system and the impact of retained enqueues on waiters. Both the current activity and the activity since the last reset are available.
For more information, see the CICS statistics tables in topic Enqueue domain statistics.
