RE: Freezing operations of LPAR

Normally I tell folks that a system at 100% busy is not necessarily a
problem. In today's
new age performance management, we like to have Processors and Real Storage
busy. And
here is a shameless plus: one of my sessions at the next Share deals with
New Age Performance Monitoring. But I do have to agree with Skip, I think
you need a serious look at upgrade(s). Seems you have 10 pounds of manure in
a 5 pound bag. Even if you tune the hell out of what you got and overhaul
your WLM Service Policy and do everything you can to improve what you got,
you won't have enough horsepower to do what you want.

The simplest way to 'freeze operations' in an LPAR is the MVS QUIESCE
command, which puts the system into a restartable wait state. I was in a
shop a long time ago that routinely used QUIESCE while switching a
communications front-end controller from one device to another. The pause
lasted only seconds and mostly worked. Years later I tried it in another
system, and VTAM got so hosed that only IPL finally straightened it out. So
try it--but don't be shocked at the results.

I'm much more concerned about the tenor of your two posts on CPU
utilization. In your other post, you ask what symptoms indicate the need
for upgrade. Mr. Bright, read your two posts aloud to yourself. You are a
veritable poster child for processor upgrade. The theme is CPU desperation.
You need help. Now.
