Hi!
I've just upgraded MQ V5.3 to MQ V6 on AIX 5.2 machine. I had one queue manager which upgraded successfully - at least it claimed so. I tried to start it and it started but in few seconds ended its execution unexpectedly with error reporting problems with semaphores. I had backup of all object definitions so I decided to delete the QM and recreate it. And here is surprise - after deleting it and creating with the same name it behaves in the same way - ends unxepectedly and all its process have problem with semaphores.
I've removed all system semaphores and shared memory segments created by the QM, but it does not help.
Any ideas?

Below I enclose the header of on of FDC files dumped by the QM:

Hi
After shutting down the queue manager, i think you haven't cleaned the semaphores or shared memory.
you must have to clean it before that.
Please let us know, did you apply the RP to it
if not apply that
Thanks and Regards
Gayathri

As you can see - from FDC - I've got fixpack 2 applied to the software.
I think the problem lays deeper - in the OS level. I cleaned all semaphores and memory segments - at least I did all I could do using ipcrm. It is possible (?) that ipcs shows semaphores/shms as removed but they actually are not.
Anyway, the problem was resolved by rebooting the machine (fortunately this was testing system), but I would like to be able to fix such problems on my prod machine without rebooting it 
But I'm interested in what system resources caused such problems.
Thank, regards

I need to change the batteries in these glasses..... 
AIX is usually fairly good about doing what it claims it's done. I've never experienced that sort of issue with ipcrm, but my stock's fairly low at the moment....

That's actually Refresh Pack 2, though, not Fix Pack 2.
Fix Pack 2 for GA would be version 6.0.0.2, FixPack two for RP1 would be 6.0.1.2, and FixPack 2 for RP2 would be 6.0.2.2...
amqiclen might have yielded more specific information than ipcrm. But I agree with vitor that ipcrm is usually reliable. Assuming you run it as mqm or root, and have full access to list and remove the semaphores you need to.

So maybe it's the batteries in my eyes that need changing....
