Ron,
At the moment I only have ESSs, but we are going to new storage soon. We

Kees,
Have you thought of putting your page datasets into Permacache (EMC) or DCR
(HDS).
This would give you true SSD performance right on the channel, which is
better than the SAS HDD emulation variety.

I agree with Kees. What exactly is your 'issue' with 'the broker'? (Assuming
that MQS is just the innocent bystander here.)

I don't know why, but anyhow back in MVS internals. There's the PART, the

In my mind, 'acceptable paging' is when service levels are being met. Usually
that means that there is little or no time spent waiting on demand paging
operations. Unacceptable paging is when service levels are not bei

There is no one size fits all.
>We are having

determine what the 'acceptable paging should be on a system?" is "it
depends".
BTW, there are possibly other reasons for poor MQ and WAS performance
unrelated to paging.

Can someone please help me determine what the 'acceptable paging' should be on
