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?
