In most scenarios, the RCDSs that were allocated to the CICS® VR server address space when the batch job that made the updates you want to back out was originally run are allocated to the CICS VR batch backout job on the DWWCONx DD statements. However, you might encounter a situation where the RCDSs are no longer available.
RCDS(NO) indicates that the RCDSs are unavailable to CICS VR during this batch backout run.
Where undo log stream is the name of the undo log stream that was defined to CICS VR when the batch job that made the updates you want to back out was originally run.
