Removing IPC resources

[mte]

Does anybody know how to remove ipc resources that have a key of 0x0 or connect them to pids. I know ipcs -mp will show the appropriate cpids but how do you find out this information for queues and semaphores, (plus -mp has shown 0 as the cpid at least once before).

Basically i have multiple Tuxedo domains booted and i want to remove all resources associated with one domain when it has died on me.

Ive tried removing the keys manually with ipcrm but when i try to remove the resource associated with the key 0x0000c09f isnt that supposed to remove all referenced resources?

$ ipcs -a | grep medwa1

i expect: ipcrm -q 856976 works. ------------ jamisar

Removing single ipc keys isnt the problem. Its that ive got two of the same 'applications' started each using ipc resources.

I know that application A uses the IPC key 0x0000c09f and application B uses 0x0000c09e and i also know that application B is dead.

How do i remove the resources that application B didn't remove, our current scripts just remove all the ipc resources for the current user.

please don't put more then 80 char per line in your post,
it's very annoying to use orizontal-bar.
