RE: QBASACTLVL recommendations.

Rob / Jim,

How many WRKWCH service monitors exist on a V7R4 system?
V7R3 has 50.

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.
