To check locks, do a LIST.READU EVERY at TCL.
Because rebooting UniVerse alleviates the problem temporarily, and the work is in sys instead of user (which is application), and there appears to be no I/O wait, I'd look at locks first, and see if the number is growing from hour to hour.
You may also go to AIX, and do a "ps -ef |grep defunct" to see if you've got a process problem. An "ipcs -mop" could tell you about other problems in shared memory, in addition to UniVerse locks. Note that as of AIX 5.x, the NATTCH column lies; a NATTCH of 0 doesn't necessarily mean a NATTCH of 0 anymore. There may be a patch for this by now.

Hi all,
There have 180 user license, some of them are using vb application (about 15 uvcs), 20 uv-net connection, about 60 telnet connection and 20 of fixed tty dump terminal users.
Some of the user are using SAME user id to login to universe is that will cost the issue ?
I have double up the swap spaces from 4gb to 8gb. but i still having the performance degraded issue. below is the usages of swap spaces before and after increment. The user claim that the system starting slow after 48 hours, so the mis guys have to restart universe every 48 hours.
[ServerX1]:/>lsps -a
Page Space Physical Volume Volume Group Size %Used Active Auto Type
hd6 hdisk0 rootvg 4096MB 1 yes yes lv
[ServerX1]:/>lsps -a
Page Space Physical Volume Volume Group Size %Used Active Auto Type
paging00 hdisk0 rootvg 4096MB 1 yes yes lv
hd6 hdisk0 rootvg 4096MB 1 yes yes lv
The above output showing that the system only using 1% of the swap spaces even i have increase the size to 8gb. Is that any uvconfig parameter that i need to configure to "tell universe" that i have 8gb of swap spaces.
tty: tin tout avg-cpu: % user % sys % idle % iowait
53.7 5451.7 24.9 75.1 0.0 0.0
Disks: % tm_act Kbps tps Kb_read Kb_wrtn hdisk1 0.0 0.0 0.0 0 0 hdisk0 0.0 0.0 0.0 0 0 hdisk3 0.0 0.0 0.0 0 0 hdisk2 27.9 116.4 35.8 4 113 hdisk5 0.0 0.0 0.0 0 0 hdisk4 28.9 112.4 34.8 0 113 cd0 0.0 0.0 0.0 0 0
Above is the output of iostat. hdisk2 & hdisk4 are configured as RAID5 with 64k of strips and mirrored each other.
Please advise, thank you
