>this has been an IBM recommendation for over 20 years. I dunno. I never liked the recommendation. If you run out of space in the Common Page DS you will crash with a wait state. It seems to me that with a PLPA page DS that is a bit bigger than your PLPA and a Common Page DS that is a comfortable cushion bigger than your CSA, then you avoid the risk of an unscheduled failure. The last time I was involved in a postmortem of this type of failure the customer had been running with a common page DS that was too small to support CSA because the PLPA had increased and stole the space. Six months later, when they started a third copy of IMS, the CSA went from 75% allocated to wait state.
I don't know whether the Health Checker checks for this situation. Tom Russell "Stay calm. Be brave.
