Active and retained states for locks

When a lock is first acquired, it is an active lock. It remains an active lock until successful completion of the unit of work, until it is released, or until it is converted into a retained lock if the unit of work fails or for a CICS® or SMSVSAM failure.

CICS supports active and retained states for locks.

Converting active locks into retained locks not only protects data integrity. It also ensures that new requests for locks owned by the failed unit of work do not wait, but instead are rejected with the LOCKED response.
