Oh yeah: I've gotten this. what you want to do is have a look at
your virtual memory tunings with "vmtune". Of particular
interest are your "maxperm", "minperm", "numclient", and
"strict_maxperm" settings. Remember that, all TSM is, is a
DB2 database, so you need to tune your VMM subsystem accordingly.
Without going intro a long, boring discussion, try this:

1) Maxperm = 40%
2) Minperm = 10%
3) Maxclient = 20%
4) Strict_Maxperm = 1

What these settings basically do is to free up real memory,
and dramatically cut down on paging; you can take both the
minperm and maxperm values down to near zero, if you're
in a severely memory constrained system.

Subject: Re: AIX Paging Space Utilization


I have also seen paging space issues my server that runs only TSM. 

OS: AIX 5.1 ML 6
TSM server: 5.1 and 5.2.3.1
Memory: 2GB
Space: 2 GB (now 3 GB)

We have logged cases with IBM, to no avail. I have check all the settings 
myself. IBM has checked everything and found no problems. I'd also be 
interested in any help.

I'm running into issues with paging space utilization on my AIX based TSM 
system. 

Host OS                AIX 5.2 
TSM Version                5.2.2.3 
Physical Memory        12GB 
Dual CPU P630         
TSM Database 1         36.6GB 
TSM Database 2        59.7GB 

I have two TSM instances running on the same box and recently (after a reboot) 
I've seen the paging space utilization increase dramatically. I've gotten to 
the point where I have to stop one of the instances of TSM and let the system 
recover paging space, then restart TSM.  Anyone have any tips? I do think I may 
have my bufpoolsize settings a little high, at 1GB for each instance. I haven't 
experimented with lowering these settings. My cache hit is 99% consistently.
