CICS VR batch backout

CICS® VR uses the before-image log records to back out updates that are made by a batch job. CICS VR undo logging can produce before-image log records for updates that are made to VSAM spheres by batch jobs.

CICS VR accepts either DASD-only or coupling facility MVS system logger log streams. Log stream copies are currently not supported by CICS VR batch backout.

CICS VR can backout all updates that are made to a VSAM base cluster with path updates when all necessary before-image log records reside on the same undo log stream that is defined to CICS VR.

The batch backout utility also supports UNDO log records that are created by CICS VR V4.2 with APAR PK44606, CICS VR V4.3, or CICS VR V5.1

Note: The keyword PROCSTEP must not be used for UNDO log records that are created by CICS VR V4.

Alternative indexes that are part of the upgrade set are updated appropriately during batch backout processing. Any alternate indexes that are not part of the upgrade set must be manually rebuilt after batch backout processing.

Allocating the RCDS is optional for batch backout of before images based on the specification of the RCDS(YES|NO) keyword in the BATCHBACK command.
