Gentleman,
I must say I basically agree with C.Mills 's approaches .
I would also like to add some aspects:
a) Once wintel/linux (and even unix/risc) are plataforms aimed by
crackers/intruders, its security adds extra costs (hw, sw HR) and
disasters/incidents to manage.

What makes you say that? It depends on the release, if you are

The CPU usage being reported is the average for a time interval of 15 or 30
minutes, whatever you have defined. At any time during that interval you had
more address spaces ready to run than you had CP to accommodate hence the CPU
contention. Good luck trying to explain that to management.
Hi
think the other way - if the cpu is 50% busy - and there is one Job coming
into the system and wants to work - in 50% of the time he can work - no
contention.
But in the other 50% of the time he cannot - cause it is busy - so there is
contention .
And yes i know - more complicated with more

OPERLOG is controlled via the VARY OPERLOG command.
You can also use OPERLOG as a DASD-only log stream. This method is only

In your example you would have 100% cpu utilization for the interval. Jacky is
trying to understand why he has less than 100% cpu utilization but still sees
cpu contention.
