The SDSF "DA" display and the IEFACTRT output could be simple bugs in the code -I would be very tempted to dump out the SMF Type30 records for the jobs in question and take a close look at them.

Apologies for the long post ... We have a strange problem on one LPAR since the last IPL in the early hours of Monday morning, whereby the CPU time used by jobs ( as displayed on the SDSF DA panel, and in the IEFACTRT reports ) is a fraction of what it should be. CICS regions appear to be using about 10% of their normal CPU usage despite being just as busy as usual. In the case of SAS jobs it seems to be recording zero CPU used, for example : Yesterday NOTE: The SAS session used 1157.31 CPU seconds and 33664K. at the end of the SASLOG Step Num: 3 PGM Name: SASXA1 in the IEFACTRT step termination report CPU (TCB): 00:00:00.00 CPU (SRB): 00:00:18.59 Friday NOTE: The SAS session used 1936.38 CPU seconds and 33652K. Step Num: 3 PGM Name: SASXA1 CPU (TCB): 00:32:16.46 CPU (SRB): 00:00:15.25 This phenomenon doesn't appear to be affecting all jobs though. I ran a small REXX that loops forever and cancelled it after 5 minutes, and it reported it had used CPU (TCB): 00:03:12.90. The IPL was to upgrade 4 CA products (MIM, OpsMVS, Sysview, CA1) and Syncsort, and apply a handful of PTFs recommended for the MIM upgrade, none of which affect CPU reporting/recording. WLM changes have been made since the IPL but none that would affect CPU; the service coefficients haven't changed, and in any case of 14 systems in the sysplex this is the only one affected. One other system shares the same sysres so is running the same levels of software and z/OS. Unfortunately this is z/OS 1.9 so I can't raise a PMR with IBM ( we're upgrading Q1/Q2 2011 ). Any ideas what could have caused this ? Not a critical problem but it's causing problems with the customer's reports Thanks Paul Beesley Atos Origin Bournemouth BH1 2NF paul.bees...@atosorigin.com _______________________________________________________ Atos Origin and Atos Consulting are trading names used by the Atos Origin group.
