M204.2565

M204.2565  token​=​token2​,​ restart​=​token3

A file can be rolled back only when using the checkpoint data set (RESTART) from the last job that updated the file. This message, which follows M204.0146 (Roll Back information is obsolete), is issued when the RESTART data set is not from the last job that updated the file.

There are two possible causes for this error:

• The file was updated by another job after the run that you are trying to roll back.
• The RESTART command points to the wrong checkpoint data set (DD, DLBL, or FILEDEF).

Comparing timestamps

The timestamps in this message may assist in identifying the reason for the "Roll Back information is obsolete" message. Model 204 creates a file-specific timestamp at the first update to a file after each checkpoint. If a job does not use checkpointing, the timestamp is created at the first update of the job only.

The timestamp is written to both the checkpoint data set, if checkpointing is active, and the file itself. During ROLL BACK processing, Model 204 checks that the most recent timestamp from the RESTART data set is the same as that in the file. If they are different, message M204.0146 and this message are issued.

Note: This is not a Model 204 internal error.

If the timestamp from the file is:

• Later than the timestamp from the RESTART data set, then the file was updated by another job after the run that you are trying to roll back. The timestamp from the file may assist you in identifying the other job. Remember that the timestamp represents the time of the first update after the last checkpoint in that job, or the first update of the job, if not checkpointing.
• Earlier than the timestamp from the RESTART data set, then you are using the wrong checkpoint data set for RESTART, or (less likely) you restored the file from an old backup before attempting to run recovery.

System manager response: Correct the error, and rerun Model 204 recovery.

Operator response: Contact your system manager.
