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'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.

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.

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)

HTTPD(8) httpd HTTPD(8)NAME
httpd - Apache Hypertext Transfer Protocol Server
SYNOPSIS
httpd [ -d serverroot ] [ -f config ] [ -C directive ] [ -c directive ] [ -D parameter ] [ -e level ] [ -E file ] [ -k start|restart|grace-
ful|stop|graceful-stop ] [ -R directory ] [ -h ] [ -l ] [ -L ] [ -S ] [ -t ] [ -v ] [ -V ] [ -X ] [ -M ] [ -T ]
On Windows systems, the following additional arguments are available:
httpd [ -k install|config|uninstall ] [ -n name ] [ -w ]
SUMMARY
httpd is the Apache HyperText Transfer Protocol (HTTP) server program. It is designed to be run as a standalone daemon process. When used
like this it will create a pool of child processes or threads to handle requests.
In general, httpd should not be invoked directly, but rather should be invoked via apachectl on Unix-based systems or as a service on Win-
dows NT, 2000 and XP and as a console application on Windows 9x and ME.
OPTIONS -d serverroot
Set the initial value for the ServerRoot directive to serverroot. This can be overridden by the ServerRoot directive in the configu-
ration file. The default is /usr/local/apache2.
-f config
Uses the directives in the file config on startup. If config does not begin with a /, then it is taken to be a path relative to the
ServerRoot. The default is conf/httpd.conf.
-k start|restart|graceful|stop|graceful-stop
Signals httpd to start, restart, or stop. See Stopping Apache httpd for more information.
-C directive
Process the configuration directive before reading config files.
-c directive
Process the configuration directive after reading config files.
-D parameter
Sets a configuration parameter which can be used with <IfDefine> sections in the configuration files to conditionally skip or
process commands at server startup and restart. Also can be used to set certain less-common startup parameters including -DNO_DETACH
(prevent the parent from forking) and -DFOREGROUND (prevent the parent from calling setsid() et al).
-e level
Sets the LogLevel to level during server startup. This is useful for temporarily increasing the verbosity of the error messages to
find problems during startup.
-E file
Send error messages during server startup to file.
-R directory
When the server is compiled using the SHARED_CORE rule, this specifies the directory for the shared object files.
-h Output a short summary of available command line options.
-l Output a list of modules compiled into the server. This will not list dynamically loaded modules included using the LoadModule
directive.
-L Output a list of directives together with expected arguments and places where the directive is valid.
-M Dump a list of loaded Static and Shared Modules.
-S Show the settings as parsed from the config file (currently only shows the virtualhost settings).
-T (Available in 2.2.17 and later)
Skip document root check at startup/restart.
-t Run syntax tests for configuration files only. The program immediately exits after these syntax parsing tests with either a return
code of 0 (Syntax OK) or return code not equal to 0 (Syntax Error). If -D DUMP_VHOSTS is also set, details of the virtual host con-
figuration will be printed. If -D DUMP_MODULES is set, all loaded modules will be printed.
-v Print the version of httpd, and then exit.
-V Print the version and build parameters of httpd, and then exit.
-X Run httpd in debug mode. Only one worker will be started and the server will not detach from the console.
The following arguments are available only on the Windows platform:
-k install|config|uninstall
Install Apache httpd as a Windows NT service; change startup options for the Apache httpd service; and uninstall the Apache httpd
service.
-n name
The name of the Apache httpd service to signal.
-w Keep the console window open on error so that the error message can be read.
