Hi all, Thanks for the responses and pointer to Kathy's White Paper. It is true that we have INITSQA coded, and that was for IPL failures which we thought were related to additions/changes to the storage configuration. However it did seem that INITSQA did not actually help much - just the action of a second IPL was enough to avoid the shortage then, and anyway that is due to requirements before the IEASYS parameter is handled by the system. I say that because we have had failures even with INITSQA coded, and reIPLing without changes appears to resolve things. These were new systems - we haven't actually had the failures that recently, so I hope my memory isn't tricking me.
As far as I understand from the White Paper, as long as you can comfortably support an IPL, there is no real reason to worry about ESQA filling and overflowing during the life of the system. She does mention that some installations do follow a policy of minimal allocation (though she doesn't recommend this). I think my likely conclusion is to check our systems needs after they are fully IPLed, and aim to cover that comfortably, but not to tune for the Healthchecker 80% recommendation. Ideally we would not have any spare ESQA by the next IPL, allowing us to manage ECSA and ESQA as a combined pool.
