In a production environment, a critical JCL SORT job is taking longer than expected to complete. How would you troubleshoot and optimize the performance of this job?

  • Analyzing the SORTWK files for optimal allocation
  • Adjusting the REGION parameter for increased memory
  • Utilizing DFSORT's STATISTICS option
  • Increasing the number of temporary datasets
Troubleshooting a slow JCL SORT job involves using the STATISTICS option in DFSORT to gather performance data. Analyzing this information helps identify bottlenecks and optimize the job for better efficiency.
