Fixing ABEND S322 (CPU Time Limit Exceeded) and S222 (Job Cancelled) in Long-Running Batch
ABEND S322 occurs when a batch job exceeds its allocated CPU time limit (due to an infinite loop, massive dataset scans, or inadequate JCL TIME parameters). Learn how to tune TIME parameters, optimize loops, and handle S222 operator cancellations.

Architectural Prevention & Performance Tuning Checklist
- Never specify `TIME=1440` on untested batch programs.
- Monitor SMF Type 30 records to establish historical CPU run-time baselines.
- Use automated alerts when batch jobs exceed 2x their standard historical elapsed time.
