Re: SAP not starting up
>will check the shared memory (ipcs -m) to see if the shared memory is released or not.
There are 3 states for shared memory:
1) memory being used, NATTACH != 0
2) memory not used, NATTACH == 0
3) memory segment removed.
If you have NATTACH == 0, you might want to know when the last use was. You can use my program attached to this thread to give you the date:

>if it is problem with releasing of shared memory, how can we overcome it
Well, you just don't use kill -9. You must shut things down normally.
If you are doing it correctly, this is an application bug that must be fixed.

Re: SAP not starting up
hi again,
> We will be carrying out the activity to stop/start sap/oracle this weekend to find the root cause without the need to reboot the server.
I would also suggest that you review your startup/shutdown script for both SAP and Oracle. It seems that the flaw lies there. As Dennis mentioned above, it may be that the application/database software are not being properly shutdown.
just some thoughts....
kind regards
