Thank you.
Here is what I currently have:
vmtune:2:once:/usr/samples/kernel/vmtune -f 1024 -F 2048 -u 64 -p 5 -P 10 -r 2
-R 256 -l 65536 -w 32000 -b 384 -c 4 -B 960 -Q 256 -Z 1536 -t 10
maxperm=10.0% of real memory
maxperm=10.0% of real memory
minperm=5.0% of real memory
maxclient=10.0% of real memory
I have not set -h (strict max perm)

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.
