Closed as program error.
Error description
An application repeatedly issued read-update, unlock, for every record in the file until it found the record it wanted to update. Because CICS does not log UNLOCK FILE requests to the file's LOGREPLICATE logstream, it exposes a problem for IIDR/VSAM where it will continue to track read-for-update requests in memory until storage is exhausted. This leads to a subscription error and replication stoppage for all replication mappings of the subscription.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All CICS users * **************************************************************** * PROBLEM DESCRIPTION: CICS does not log UNLOCK FILE requests * * to the file's LOGREPLICATE logstream, * **************************************************************** Because CICS TS does not log UNLOCK FILE requests to the file's LOGREPLICATE logstream it exposes a problem for IIDR/VSAM where it will continue to track read-for-update requests in memory until storage is exhausted. This causes a subscription error and replication stoppage for all replication mappings of the subscription. A second problem where double logging of a read-update record occurs when RLS browse for update is used is also fixed.
Problem conclusion
CICS will now journal a UNLOCK RECORD for an UNLOCK request against a VSAM file when replication logging is active. IIDR for VSAM product may be updated to exploit the new UNLOCK record.
