M204.0175 Roll forward optimization error
The sequence number of the CCARF data set record containing the checkpoint rolled-back-to is recorded during the first pass of roll forward. After rewinding the CCARF data set, pass two of roll forward reads CCARF forward without examining the records read until it reaches the record which it believes contains the rolled-back-to checkpoint. When this record was examined, that checkpoint was not found.
Model 204 rewinds the CCARF data set again, and reads from the beginning examining each record until it finds the rolled-back-to checkpoint or finds and EOF marker.
System manager response: Recovery may complete successfully, though it will take a bit longer to run. In any case, save the audit trail, CCAPRINT, the console log, and copies of both the CCARF and RESTART data sets. Report the problem to Technical Support.
Operator response: Contact the system manager prior to taking any further action.
