shared memory deleted

Hi,
I have a situation in which once I start an application it marks the shared memory as deleted.

Please any help on what I can do to unmark this? Manually or is ther a fix
HPUX11.11, oracle 8.1 Tuxedo 7
What could be causing this?

THANKS!!!

An application or a process can mark it that way. But why you want to get rid off it?? If application does not want it, it should take care of it. Do you have problems with this machine??

Thanks Anil,
The application log shows a shared memory error.

It never used to mark it for deleted and am just wondering..........

What is the error that you get?? Give error message. Did you reboot the system. With ipcrm you can delete a shared memeory segment. (You should use it only on the semaphores which show NATTCH as 0. Check it with ipcs -moba)
