Re: memory pools

Cyndi,

There are some things you can do. Advice:
1. Use the autotuner.
2. Use the shared pool size min&max with reasonable numbers
3. Make all pools *CALC

5. Tune your system values - QACTJOB, QADLACTJOB and same for QTOT
6. Tune your socket server pre-start jobs for better thresholds
7. Timeslices are a silver bullet - email me for the secret :-)

Hope that helps,
Trevor

Subject: memory pools

Everyone,

We have been receiving complaints from users that the system is slow for approximately one month. None of us are tuning specialists, so directions to the manual must be specific.

Here is the System Status screen:

Pool 1,3, & 4 are set to Calc, pool 5 is static.

As you can see below, most of our subsystems are in pool 2. Byteme (programmers sybsystem) and QINTER are shown in 2 & 4. QUSRWRK is in pool 2. We have been busy beavers and have nearly 80 jobs running in QUSRWRK (socket servers that are in TIMW mostly).

Our interactive users are fussing that things are running slowly. There are 60 to 80 interactive users. We have an enterprise box, model 810, 7406 processor feature.

Do we need to reassign where pools are ? Maybe get another chip of memory ?

Suggestions welcome.
