CICS VR has been requested to back out updates made by the specified batch job. Some of the updates to back out have been made to VSAM data set dddd. However, there is a discrepancy of the date set type for this data set. The data set type of the data set according to the catalog entry is datasettype1, and the data set type that was recorded in the before-image log record is datasettype2. This VSAM data set might have been redefined or altered in some way after the batch job specified for batch backout processing completed.

Batch backout processing stops.

CICS VR can only back out updates made to a VSAM sphere that contains the same attributes of the VSAM sphere that were recorded when the original updates were made. If the specified VSAM data set with the data set type recorded in the before-image log record no longer exists, batch backout of the specified job is not possible. Restore the affected data sets from their latest backups and either rerun all relevant transactions or perform forward recovery. If you specified the DSNEXTENSION keyword, verify that a VSAM data set with the original VSAM base cluster name and the entered extension appended exists. The attributes of the VSAM data set must be identical to the original VSAM data set.
