We have a new installation that has problems in that paging space continues to
grow until it hits 100% over about 8-10 days. Having setup a cron job on AIX
that logs paging every 5 minutes, I determined that essentially the only time
paging space increases is when backups are running. We reboot to clear problem.
Details:
TSM Server is 3.7.4.0 on AIX 4.3.3
Client is:
IBM RS/6000 Silver SP node w 2x 332 MHz processors and 1GB RAM and 1GB paging
space. (Node is standalone and not "fenced".)
AIX 4.3.3. Maint Level 7
Sybase ASE 12.0.0.1 (Using raw logical volumes for db - vendor insisted on
this)
SQL Backtrack 4.5.00 with OBSI module 2.5.00
TSM Client 4.1.2.0
The paging space will jump up about 4 -8 % per day. I do SQLBT backup of
database at 12:15 am and regular FS incremental at 2:15 am. Paging space
incresases when each backup starts and does not go down.
I saw info on Tivoli site that TSM client 4.1.0.0 (which I was using) had
memory leak problems on NT and possibly other platforms, so I downloaded what I
saw as latest AIX version, 4.1.2.0 and installed - no change.
I have 4.1.0.0 on other AIX and NT boxes with no problems.
We had ML 6 of AIX on and was happening with it too, upgraded to ML 7 for other
reasons and no change.
This is a new install, users not on system yet, Database is getting info from
another system and apps are being developed to generate reports from this DB.
Last night I disabled both backups and NO PAGING SPACE increase occured.
One other bit of info (maybe confusing). Using the svmon command, it seems to
indicate that Sybase is the user of the growing paging space!
Any ideas folks? It is not obvious to me how a regular FS incremental can
cause Sybase to use additional paging space.
If no one has a solution I will open a ticket with Tivioli to start with and
then proceed down the line one vendor at a time.
Thanks for your head scratching,
