out of process memory

[Jeff Hoevenaar_1]

We are getting "out of process memory" from our Oracle applications. It appears
that the application is not releaseing memory. We have increased the maxdsiz,
maxssiz, and maxtsiz parameters. Is there a way to track and record which
process is not freeing up memory. Or is there a way to see if the kernel
parameters sizes are being reached?

Try using Glance, It will allow you to find processes using memory and how much
is used by them.

A 90 Day trial is on one of the support CD's that come with your system.

I think that's a typical program problem, revise your source program or trie
you with old version of program.

hi,

Check for the swap space.

Hi Jeff,

I had this problem initially when we install oracle 8.0.5 on HP K580 running HP-UX 10.20. Make your swap space upto 2.75 Gb, have good CPU upto 1Gb combined.
Run ipcs -mobs|pg check the shared memory and the semaphore values.
Goto to IT Resource center hot documents and search for this documents "Understanding Shared Memory on PA-RISC Systems and Oracle: configuring Oracle 8.0.5 on an HP-UX 10.20 system" and do some readings. I will attach my kernel parameters to guide you for the changes.

Best Regards

Chris

Out of memory falls into two categories: lack of virtual memory (which is swap space) and hitting a memory limit. maxdsiz should be increased to the max (940 megs) to allow large programs to run. Then check virtual memory with:

swapinfo -tm

The last line (total) indicates whether you are out of virtual memory. If you haven't already, turn swapmem_on to 1 in the kernel to allow RAM and swap to be additive. Otherwise, you'll need as much swap space as you have RAM (minimum).
