Apples and oranges. The only meaningful relationship between real memory and virtual memory is the paging rates. Of course, if your system paging rates are zero, you might consider allowing various applications to allocate more virtual storage which might have an impact on your auxiliary storage allocations. CSA and SQA are not relevant to this context. ECSA and ESQA should have been sized using other criteria. <SNIP> I'd been thinking about this. Wouldn't the ESQA increase in size to track the increased number of page frames (needed by RSM)? This would push ECSA a bit higher (address floor is what I refer to here, not size). HSA will get moved. And it might increase in size (I don't know how IBM handles tracking of storage for LPARs -- I knew how this worked on Amdahl 5990-A machines once upon a time). But other than those things, I can't think of any thing else that gets changed.
