Incident: S322, the job that never finished
PAGE 04:45 SEV2 - Job PAYCNT ended ABEND=S322 in step RUN PAYCNT normally runs in under a second; tonight it used its whole CPU time limit
PAYCNT counts and totals the daily payments. Change CHG31210 rewrote PAYCOUNT 'for clarity' yesterday. Tonight the job ran until the system cancelled it with S322. Find the bug, fix the program and get the right count and total.
What you will do
- Read the abend and the step's CPU use
- Find why the loop never ends
- Fix, rerun, check the numbers
