Various conditions can cause CICS® VR batch backout to terminate processing, for example, a VSAM sphere being unavailable. CICS VR writes an appropriate error message to the data set allocated to the DWWMSG ddname to help you resolve the issue that caused termination.
In some cases, you might be able to resolve the issue and rerun the CICS VR batch backout job. Rerunning a CICS VR batch backout job, after it previously terminated abnormally, does not cause any duplicate processing. Any before-images that were applied during the previous execution of the failed batch backout job are ignored the next time the same batch backout job is run. Therefore allowing you to remove successfully the updates made by the specified batch job steps.
