> Let's hope they really don't do any paging. I don't suppose many installations will be really paging (constantly) these days. Paging will be more concentrated to spikes and at those (seldom) moments you really need the PAV exposures badly. With larger memory sizes, dumps will be larger, causing large page-out bursts and more subsequent page-ins. You don't want those page-ins to perform badly in peak time and therefor you want a certain number of PAV exposures on your total page space. > > Mmmmm - maybe that old seldom ending channel program wasn't such a bad > idea after all. > A joke of course? For the SECP you needed to decicate a volume to 1 pgds. If you do that now, you have 2 PAV exposures, say 2 SECP's per pgds. If you don't dedicate volumes to 1 pgds, you now have better performance too than in the SECP situation.
