When the U3970 abend occurs as the result of a journal sequence overflow problem, the appropriate resolution is as follows:
1. Restart the CA Dispatch STC using the special command S DISPATCH,START=DSSTAR00 so that no subtasks get restarted.
2. Confirm a WARMSTART SUCCESSFUL message is received during startup and as soon as CA Dispatch is all the way up, issue the 99STOPCADS command to initiate the normal CA Dispatch shutdown routine.NOTE:
During normal CLEAN shutdown processing, you may see messages containing the text of "ABORTING TASKS" and/or "ABENDED WITH CODE SHUT". Messages containing this specific text are not representative of a problem. These are normal shutdown messages and are to be expected.
3. Submit the CADSJCL library job DSEXJFIX with the MIGRATE symbolic set as MIGRATE='LE' to initialize all four of the existing journal files.
4. Review the output from the DSEXJFIX jobs execution and ensure that the job ended with RC=00.
Initialization of the journal files as outlined above will reset the DMCJTSEQ field counter and will also clean up any other journal file corruption or fragmentation that may have occurred over time.
