Stopping SAP and ipc processes owned by sidadm processes remain

[Former Member]

We are running AIX 5.3. ML5 and have been in production for 2 months. We have noticed that during stopping SAP the ipc queues still have sidadm processes, a large number of them. It should clean up but it doesn't. Has anyone a solution, I run cleanipc 00 in the shutdown script, but does anyone have an idea why this hasppens?

If we dont cleanup (delete) the entries shmem and semaphores woned by sidadm...it will not start up if you stop and start several times.....

Thanks

You might be able to run this command as root from within the script by using the 'sudo' command.

Hope that helps.

Hi,

Please run command "slibclean" as root, it will clean all the semaphores owned by sidadm.

If you want to remove them "manually" you will need to execute (as root):

cleanipc 00 remove

The reason for that behaviour can be, that, depending the version your run, there will still be a process "sapstartsrv". If you kill that one (with kill -15), do you still see the share memory segments?

You can also try to switch the management of the semaphores to shared memory, check
