512k pages, 4 kB each equals 2 GB. So you left no space for AIX, file
buffers, TSM code, etc. Consequences: excessive paging

Hi Bill,
Another thing that came up in our discussion was that the DB
buffpoolsize should not exceed 131072 (128K). You might want to try that
was well. Sounds like you have little to lose, like
: OS390 TSM Performance questions.
Hi all,
I followed your discussion with much interest, as I'm suffering from
huge performance problem problem too. Unfortunately I'm not under OS390,
but using AIX 4.3.3 : could someone tell me if there is some some trick
like this one, that should be considered

Hi,
I wanted to clarify, or perhaps retract, something about the 'show memu
SHORT' command that has been mentioned in this thread. Not surprisingly,
the numbers you get from this command
Richard,
I totally agree with you, but if I tell you that my current situation
happened due to the help from IBM support, what would you answer ? ...
I'd agree with your frustration, Arnaud, given the premium price being
paid to a top vendor. Generally, though, unless a vendor specialist is
one
Well you dont mention the stripe size used for the database and logs file
systems.
We had our database and log on a striped filesystem and we had a really bad
expire perf srtipe size was 64 kb.
From memory all database actions are 4kbyte.
Are these ssa disk if yes do you have write cache

Hi Bill,
We are running TSM 4.2.2 on os390 2.10 pn a 9672 (5 cpus)
I have region at 512 mb. and bufferpool at 48 mb.
I am running alongside other business applications, and it is only when
might wish to provide.
Kindest Regards,
Mark Darby (or, as know by my peers and close associates - Mr. Verbose - you
see why?)

Hello, Al.
We have much to share
Hi,
We seem to be experiencing symptoms similar (identical?) to Alan's.
We're at z/OS 1.2, running on a 2066-002 w/ 8GB of memory and virtually no
paging; TSM is at 4.2.3.0.; database is 55% of 106 GB. Network
connectivity is via GB ethernet. Disk pool is 190GB on an ESS. Nightly
backup load is
with!
OK Al, just stay calm the men with the white coats will be along shortly!
At least it would be vacation time! (:
Al

It is totally counter-intuitive to me that reducing the memory
footprint would yield these results, but it has.
Is your system memory-constrained? Are you experiencing high paging
rates? It's possible that increasing TSM's memory demand increases
