No single 'query' command, no. You should enable and configure PERFKIT
(Performance Toolkit) .. once you do so, you can query many performance
aspects of your system, including which users are using the most cpu,
memory, io, paging, etc..

Well, to *support* something on a box you also have to have tested it there.
At least that's the grief I get from non-IBM vendors when I ask for product x
for Linux on z! It may run, but they didn't invest the testing dollars. I
suspect that's part of it too. Running tests on those >4 yr.
I somewhat agree. I'm confused by IBM's z "philosophy". I remember when the
S/370 arch was around and IBM was targetting from mid-size to large shops (4331
was __small__!). Now the z people seem to be like Bentley dealers. If you're
not a multimillionaire, you don't even need to consider a Bentl

It's really up to you and your management's direction.
If you only have one system to maintain, once you get the hang of it it's

I'd say it depends on the purpose of your 2nd level system.Do what you
would normally do when applying maintenance... do you put it on 1st or 2nd
level first? If your 2nd level system is meant to be a z/VM 'test' system,
then it seems like you're already committed to that level of effort.

Sorry for the delays in the speed-of-light upgrades. Barring further
interference from the future, you should have a prototype to play with two
weeks from the 11th of last November...8-)

Would you recommend putting this 5.4 zEnterprise compatibility maintenance
on at Level 1 or Level 2.
We currently have both environments for 5.4.
I suppose the quickest and easiest (maybe dirtiest too?) way is just to
put it on at Level 1 and fall back to CPOLD if there is a problem.
