IPC And memory leak

[Safarali]

My system one oracle user showing high consumption of memory, is it any way to check the memory leak with IPC without shutting oracle

Shalom,

Works on Linux HP-UX and Solaris.
This script is beta and I'm improving it regularly, so bookmark the site.

Detects leaky processes.

also:
ipcs

ipcrm

The latter command lets you clear shared memory blocks if they are not in use. If you hit something that is active, its possible to disable Oracle.

Thanks for your support
I got the following output how I know there is a leakage in the memory
sh memtest
utility is running....

safarali,

You can use kmeminfo tool from HP to collect the memory info for a start. Please log case to HP support to obtain the tool

Also you also can use perfview to view your measureware data to look at your memory utilization.

Usually memory leak can be fixed by patches.
What HPUX version you are running?

please assign points

IPC only shows you shared memory so if a single user is consuming a lot of memory, check if the memory is local to the user's application. Do this by sorting all the processes by local memory usage:

UNIX95=1 ps -e -o vsz,ruser,pid,args | sort -rn | head -20

The first column shows local memory in Kbytes.

Thanks to every one
