    Hi guys
    i am facing an issue with my server and there is a process RGRARG which is consuming 85% of CPU.

    server details :We have a TL 6 with AIX 5.3 installed on p570 with 8 LPARS

    is there any way to trace out what this process doing ?

    Thanks

    Hello,
    use truss to find out what this Process is doing.
    man truss
    will guide you in usage.

    Hello,
    If you use the command e.g. truss you see what the Process on your System does.
    Does it READ, WRITE is it WATING, SLEEPING ...
    What I meant with
    "We do not know what your Application does?"
    is, we do not know what system Calls your Application will execute.
    You have to discuss, that your Process is right and not running wild, with the creator of the binary or Application.

    Maybe proctree can help you. (also use nmon for manage simple perf overview)

    If your intention is to find out what is doing, you will need to work with the Application Support group of your organization and look into the application logs.

    If you want to confirm what ports and system resources its using you can use the 'lsof' utility which will give you something like this. This will list the listening port which you or the Application Group may have documented. This will confirm which component of the OF application it is using.
    f60srvm 307238 appltrn cwd VDIR 38,2 0 0 /u01/oracle/TRN (/dev/lvu01trn)
    f60srvm 307238 appltrn 0r VCHR 2,2 0t0 0 / (/dev/hd4) (like device special /dev/null)
    f60srvm 307238 appltrn 1w VCHR 2,2 0t0 0 / (/dev/hd4) (like device special /dev/null)
    f60srvm 307238 appltrn 2w VCHR 2,2 0t0 0 / (/dev/hd4) (like device special /dev/null)
    f60srvm 307238 appltrn 3u IPv4 0xf1000600032ac398 0t0 TCP *:9055 (LISTEN)
    f60srvm 307238 appltrn 4u unix 0xf10006000346e008 0t0 ->0xf100060003131c08

    Again, this is not a system process, but an application process.

    One other OS utility you can use to obtain the file descriptors that are open or using the PID in questions is to run the following and redirect to a temporary file. This will probably help point to name of the OF resources in use, which may help narrow down which OF application on this system:

    procfiles -n <PID>

    Good luck.
