>But a GTF Trace probably can. I would look at GTF TRACE or VSM Traces.
But this will monitor VSM calls, not CPU usage. I understand the GETMAIN/FREEMAIN are expected, but only every now and then, they go wild. I don't see how GTF can help here. I don't know the details, but I know we have some automation in place to detect high CPU users (jobs). AFAIK, it is based on MainView z/OS detecting such a job and then writting (WTO) a message, which in turn triggers automation. Do you have some tool like MainView or Omegamon? -- Peter Hunkeler ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
