Setting the CICS VR backout control parameter

The CICSVR_BACKOUT_CONTROL parameter in the active IGDSMSxx member of SYS1.PARMLIB is used to control whether CICS® VR must automatically submit a batch backout job if a batch job encounters a failure, system or user abend.

The following values can be specified for the CICSVR_BACKOUT_CONTROL parameter in the active IGDSMSxx member:
SUBMIT NONE
CICS VR does not automatically submit a batch backout job when a batch job encounters a failure, system or user abend.

SUBMIT NONE is the default value for the CICS VR backout control string.

SUBMIT ABEND
CICS VR automatically submits a batch backout job when a batch job encounters a failure, system or user abend. The batch backout job attempts to remove the updates made to the VSAM spheres by the batch job step that was in progress when the abend occurred.

If SUBMIT ABEND is specified, make sure that the batch backout JCL skeleton has been updated to conform to your environment. See Running CICS VR batch backout for more information.

Note: In the situation where
  • SUBMIT ABEND is the currently active backout control string
  • ENABLE SYNC is the currently active undo logging control string
and an undo logging error occurs, CICS VR cancels the batch job, and attempts to automatically submit a batch backout job to remove the updates that were made to the VSAM spheres by the batch job step which was in progress when the logging error occurred.
Examples:
CICSVR_BACKOUT_CONTROL(SUBMIT ABEND)
CICS VR automatically submits a batch backout job when a batch job encounters a system or user abend.
CICSVR_BACKOUT_CONTROL(SUBMIT NONE)
CICS VR does not automatically submit a batch backout job when a batch job encounters a system or user abend. A batch backout job can be manually submitted to remove the updates made by the batch job step that was in progress during the abend.
