The amount of response time that process preemptions are costing your
performance is measured as the amount of response time in an extended SQL
trace file that is not accounted for by the sum of your file's c values at
recursive depth zero, plus the sum of your file's ela values.

Cpu average load. =20
Guys, I have started using big brother for monitoring our Unix/Oracle
systems. I am getting alerts on the cpu utilization:
dohsdb10.doh.ad.state.fl.us.cpu yellow Mon Nov 29 18:36:36 EST 2004 up:
55 day(s), 12 users, 139 procs, load=3D171
LOAD AVG on dohsdb10,doh,ad,state,fl,us is 171
What is a good load average per cpu - this is a Solaris 2.9 smp machine
with multiple cpu's - what should I expect??? How can I tell if this
cpu utilization is affecting performance on the host?
Thanks,
Paula
