Good morning list.

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
