You need to lower the maxclient setting first and then you can reduce
maxperm.
But as noted if your using jfs2 filesystems it is not a good idea to lower
maxclient.

Subject: tunables on AIX 5.2
Hi,
I have AIX 5.2 ML01 with TSM 5.2.0.0 as the only application running on the
system. In fact the only things I have installed here are TSM (server and
client) and the management software for the FastT700 that it is using. I am
having a problem with virtual memory. I have 8GB of ram. TSM's buffpoolsize
is set to 4096000 (should be 4GB). When I boot the system, as much as 8GB
of the swap region is utilized. This slowly increases and finally craters
the system.
I have looked at most of the articles on the list and they suggest as a
first step to dealing with virtual memory issues, setting Maxperm% to 40 (or
thereabouts) and minperm% to 10. When I execute this on AIX 5.2 I get the
following:
usr/samples/kernel # ./vmtune -P 40
vmo: 1485-111 Invalid value 40 for tunable maxperm%
Value for tunable maxperm% must be greater than or equal to 80, value of
tunable maxclient%
FYI, my DB and log segments are on filesystems rather than raw lv's. Any
ideas?
