Re: Massive Non-DB paging on (nearly) quiescent system

Hi Jason! It doesn't "matter". I was just taking an inventory and
anomalies always irk me. Our local replication machine (which actually
does more replication than the HA machine, because it's used for backups
and daisy-chains to a development machine) has almost zero paging. But
yes, I suppose I could suspend QEDD and see what it looks like.

I was just looking for a more surgical method than that. :)

One thing you could do here first, close down QEDD and see if it
stops. If it does then you know for sure that QEDD is causing it.

But, since it's an HA system, and if it's running normally, does it
even matter?

So I've got a machine whose only official purpose in life is as an
offsite HA machine. It talks to our production machine over an
adequate but not extremely large pipe. It's very simply configured
with three pools, machine, base and spool. It's running at 8% CPU
utilization, and that's nearly all due to the QEDD (replication) jobs
(and an occasional appearance by our good friend QDBFSTCCOL).

And yet, I'm getting a ridiculous amount of Non-DB faulting and
paging. I mean it's crazy:

It's been a while since I tracked this stuff down. Where do I go for
an initial look? And WRKSYSACT shows nothing out of the ordinary
either. The QEDD jobs, and tiny percentages from things like
RMTMSAFETA and SMXCAGERnn.

Thanks as always!
