Re: Timeslices

If you have Performance Adjuster turned on (QPFRADJ system value), it will
manage shared pool sizes and shared pool activity levels to optimize
overall system throughput.
In my experience, it does a fairly decent job.
So this discussion about activity levels is rather theoretic.

However, there could be configurations where Performance Adjuster gets
confused - then a manual configuration is required.

The whole discussion about activity levels puzzles me a bit.
36 hours ago I set the Activity Level to 100 for all pools (expect the
last little one). Since then the system has steadily decreased
those from 100 to (now) about 65, falling about 1 an hour.
Does this mean that it doesn't matter what I set the activity levels
to? Are they automatically adjusted to a more reasonable (?)
level?
