Resolving restart abends caused by indoubt checkpoints
A restart of an abended IMS batch job ends abnormally if the last checkpoint ID that was supplied by IMS Program Restart Facility is indoubt. If such an abend occurs, determine the correct checkpoint ID and restart option for the job.
About this task
Indoubt checkpoints most often occur for BMPs that are active at the time of an IMS control region abend or for canceled DL/I batch jobs. The condition is caused when the next checkpoint ID that is requested by the application is not confirmed to IMS Program Restart Facility, presumably because the logging request did not complete.
If a restart abend from an indoubt checkpoint occurs, determine if you must restart the original abended job by using the last indoubt checkpoint or the last verified checkpoint. You can also restart the job from the beginning.
Indoubt checkpoints are flagged by messages IRT010W and IRT017I.
Procedure
If a restart of an abended job ends abnormally with a PRF U3625 or an IMS U0102 completion code, review the IMS logs and message DFS682I. With this information, select one of these actions:
