Are you running a 6th pool? The pool sizes shown add up to 2.7GB. I know we run 16GB with 11GB assigned to the pool doing web work and our new system is planned to have 32GB. I think the 1.3GB you have assigned is a little light. Any possibility of adding more RAM?

Hi Mike,
Currently, we are sitting with these values in our system status screen:
% CPU Used: 87.3%
% DB Capability: 60.9%
Jobs in system: 4460
% perm addresses: .032
% temp addresses: 2.519%
Aux storage
System ASP: 387.5G
% system ASP used: 65.8375
Total: 387.5G
Current unprotect used: 9490 M
Maximum unprotect: 9911 M
System Pools
SP Size Res. Max
1 182.38 108.87 +++++
2 1324.62 3.37 119
3 80.00 .00 10
4 830.00 .00 47
5 380.00 .16 10
Not sure if you need to know the page faults...let me know if it helps.
It is running on a P10 CPU, CPW I believe is 1000 pooled INT/BCH
Thanks!

Could you give us a little more info on the specs of the 520. CPW, RAM, disk and how you have RAM split up into pools? (WRKSYSSTS).

Hi All,
I'm wondering if anyone can suggest a course of action to help determine out bottlenecks in our AS400 and a plan to improve performance?
A few years ago we upgraded to a 520-9406 machine. However, I have noticed over the past two years that our CPU usage has slowly been creeping up as new programs have been added. As it stands right now, whenever I check CPU usage I hardly ever see it below 80%. Usually it is in the 90%+ range. I know it is frustrating to our users, and I can't blame them - I would hate to wait for jobs to finish for long stretches at a time.
I would like to determine where the bottlenecks are occurring, and I wonder if the group has any suggestions? Looking at the active jobs, I suspect it may have something to do with all of the web pages that hit the 400 on a regular basis - I see an awful lot of QZDASOINIT jobs occupying a fair chunk of CPU usage. There are other jobs that run regularly that consume a fair amount of usage as well.
Are there any free / built-in programs I can use to analyze the 400 to see where and when these bottlenecks occur? I do have a HW/SW contract on the 400, so could I have IBM come in and perform an analysis on the system to determine our problems? I'd hate to throw a bunch of money upgrading the main storage/DASD/CPU to P20+ if that isn't really the problem (and I'm sure our senior management group would be less than happy as well).
Any ideas would be most appreciated!
Thanks!
Brian.
