Yes, it was. The idea came up somewhere after release 1 was in the field
a while and APARs had come in against it and PTFs had been applied and
update releases fixed problems.

Wasn't that kind of long in the tooth by then? As I recall, 1968 was when
Release 14 came out.

That got me too. First I thought we had a bug. But it appears to be a feature.

It depends. With WLM inits the queue delay is part of the equation in

My point was this: Most shops who convert to WLM INITs do it for all work
or the vast majority of their work.
Page out is asynchronous and will only affect paging performance to the
extent that the channel/device is not available for demand page-in.
By %USE I meant page slots used, meaning increase in page out.

too much juice wasted on paging out/in.
The issue is no
I'm curious. Why does the percent of page slots keep increasing over time.
I would think that when a job ends, all its page slots would dropped, and all
the space taken in the page dataset would be released. I have noticed that kind
of behaviour also. I suspect that long running started tasks ar
