Re: QBASACTLVL recommendations.

Interesting that V7R4 uses so many more activity levels. I'll bet that has
more to do with IBM exposing them than an actual increase in activity in
that pool. In the past they (IBM) has hidden activity they considered not
manageable by the user anyway so why show it to them. We don't have
sufficient load on our V7R4 systems to see that effect on our system so it
will be interesting to watch.

Is the job table significantly fuller as well?

Actually it isn't the paging and faulting which concern me as much as the
activity level being exceeded thus stopping all new jobs from running. An
absolute killer. Why have we had to more than double that when we went
from 7.3 to 7.4?
We're doing a bunch of monitoring to see what is consuming that.

Rob:
In my world, if the activity level of *BASE needs to be 6050 or whatever
for that system, I set it and forget it, there's precious little reason to
lower it at that point.

I would want to know in your case why so much paging/faulting in that
pool? That means most likely all the remote SQL communications is going in
there, and it's likely there are other jobs running in *BASE that should be
moved out. I always tell customers if you application is running in *BASE
alongside many IBM processes, then the whole system slows down due to
resource contention with the IBM jobs.

I'd be far more concerned about that.

Hello Rob,

Am 31.10.2019 um 15:32 schrieb Rob Berendt <rob@xxxxxxxxx>:

With our issues IBM has recommended we turn off the adjustment at IPL
for fear of an IPL setting it to too low. I agree that normally you want
an IPL to adjust this to take advantage of new memory you may have just
added.

I think that it's better to have adjustment only when running (3) but not
an IPL as default: The configuration should adapt to running conditions
and
stay there, not these at IPL time.

When someone is adding more memory, adjustments will be done more slowly
but eventually they'll get through. This is even more true when doing
memory adjustments to an LPAR while running, so it's kind of a "no
brainer".

Any thoughts on that?

Besides, if there's physical memory to be added and immediate remedies
must be taken, one can easily set adjustment to IPL time (1 or 2)
temporarily before shutdown.
