RE: CPU priority for AIX 5.3 with mixed workload
Have you tried turning off SMT on your test system? From what I can
tell, smtctl can change this on-the-fly. If that's the case, perhaps
SMT could be turned off for the duration of your batch job.
Probably overly simplistic, but maybe worth a shot. And now to ask my
SA about SMT... :)

Subject: CPU priority for AIX 5.3 with mixed workload
My customer is running a 10.2.0.2 database on AIX5.3, p590 with 14 Power
CPUs and SMT enabled.
The day workload is 8000 dedicated user connections plus 5 or so
long running reports.
They have an overnight batch job that is CPU bound and taking 8+ hours
On an unladen identical test system the same batch job completes in 2.5
