Please let me know what other information I should post that will help to diagnose this issue.
Thanks!
This vmo -a output is either incomplete or indicates that you use some very old TL. If you did not do this yet: I suggest you upgrade your AIX to the current TL 10 SP5 or SP6. The VMM differs between some ML/TL considerably. (You might be below 5.2 ML4.)
Your application uses (together with kernel and shared memory) about 860MB RAM under load. This is pretty close to your minperm setting of 20% of your total RAM. The next tuning step would be to find out whether your application causes the trouble because it cannot allocate enough memory during operation as seen in your first post. To find out change the VMM settings.
This configuration change will enable your server to use more memory for the application by reducing memory available for file caching. If it works out as expected paging into the filesystem should stop eventually. The change will be active without reboot.
You might watch the config change's effect with vmstat. If you like the server's behaviour fix the settings by issuing the command again with a leading -p. If you don't the server will start with its default settings after the next reboot.

Hiya all,
I am a newbie sysadmin to AIX, i have worked on HPUX for 3 years.
I have started a new role with in an IBM house and because there is me and one other there are a couple of issues I cannot work out:

I'm doing performance testing for one application which works on AIX.
But I don't know which performance parameters of memory need to be collected. Now, I just know very few:
1. page in
2. page out
3. fre
They are all collected by "vmstat" command.
I want to know, except for above... (2 Replies)
Gurus, i have process that runs 5 times a day.
it runs normally (takes about 1 hour) to complete in 3 runs
but it is takes about ( 3 hrs to complete) two times
So i need to figure out why it takes significanlty high time during
those 2 runs.

Hi Guys,
This is the situation I am in. Provide your views and input where should I start?
I have one P7 test server and a p520 production server. the job is taking pretty long on the P7 test server when compared to the P5 production server. below is the full detail.

Hello
I am new user of AIX; I have only basic knowledge of the UNIX commands, and I want to create script that will monitor the performance and resources usage on AIX 6.1 machine.
Basically I wan to start a loop that will grab, every 10 seconds, the CPU usage, the memory usage, the disk usage,... (1 Reply)
Hi,
I would like to hear your thoughts about this. We are running our Data warehouse on DB2 DPF (partition environment) and I have notice that sometimes we hit the Asynchronous-I/O-Processes peak. DB2 relies heavily on Asynchronous I/O so I would believe this has an negative impact.We are... (10 Replies)
Hello,
I encounter some performance issues on my AIX 5.3 server running in a LPAR on a P520. How do I investigate performance issues in AIX. Is there any kind of procedure that takes me to the steps to investigate my server and find the sub systems that is causing the issues?
The performance... (1 Reply)
Hi,
I'm supposed to capture many performance stats on AIX 6 and stuck up with below:
Priority queue
Disk cache hit%
Page out rate
Swap out rate
Memory queue
I see vmstatis helpful for "page out" but not sure how to get the "rate".
Could anyone please let me know how to get these... (4 Replies)

x11perfcomp
X11PERFCOMP(1) General Commands Manual X11PERFCOMP(1)NAME
x11perfcomp - X11 server performance comparison program
SYNTAX
x11perfcomp [ -r | -ro ] [ -l label_file ] files
DESCRIPTION
The x11perfcomp program merges the output of several x11perf(1) runs into a nice tabular format. It takes the results in each file, fills
in any missing test results if necessary, and for each test shows the objects/second rate of each server. If invoked with the -r or -ro
options, it shows the relative performance of each server to the first server.
Normally, x11perfcomp uses the first file specified to determine which specific tests it should report on. Some (non-DEC :) servers may
fail to perform all tests. In this case, x11perfcomp automatically substitutes in a rate of 0.0 objects/second. Since the first file
determines which tests to report on, this file must contain a superset of the tests reported in the other files, else x11perfcomp will
fail.
You can provide an explicit list of tests to report on by using the -l switch to specify a file of labels. You can create a label file by
using the -label option in x11perf.
OPTIONS
x11perfcomp accepts the options listed below:
-r Specifies that the output should also include relative server performance.
-ro Specifies that the output should include only relative server performance.
-l label_file Specifies a label file to use.
X DEFAULTS
There are no X defaults used by this program.

Mark Moraes wrote the original scripts to compare servers.
Joel McCormack just munged them together a bit.
