I tried to install Fix 6.0.2.8.
After stopping all queuemanagers I found two shells (sh) and two zombies.
I stopped the shells with kill -9 and the process list was clean.
While installing I got the message that there are used IPC ressources.
I used amqiclen, but I still get this message.

Any idea?
Thanks
Gunter
Solution:
- no access rights for other on /var/mqm
- checkinstall is called by user noaccess and needs access to /var/mqm
This happend on two boxes. I installed FixPack 6 and 7 before and have no idea when and who changed the permission.

This seems to be a problem with the amqiclen component that comes with MQ.
Can you try this.
1: /opt/mqm/bin/amqiclen -c -v (try cleaning all IPC processes if any )
2: mv /opt/mqm/bin/amqiclen /opt/mqm/bin/amqiclen.bak (rename the amqiclen )
3: Follow the normal pkgadd now.
Hope this will help.  |

If you prevent amqiclen from running or run it manually in the wrong way you can harm your MQ data, so please resist any suggestions to run it unless IBM advises it thru a PMR.
Anyhow the OP's post shows there were no IPC resources (message queues, shared memory, semaphore sets) in existence. So there is nothing for amqiclen to clean up.
I suggest to open a PMR for this and ask for someone to look at a "truss" system trace of the failure.
Example truss options, which will give LOTS of output in a file called tracefile.txt:
| Code: |
| truss -aefld -u"*::*" -wall -otracefile.txt PROGRAM ARGS... |

I edited the post a few days ago. The Problem is already solved, the only question is "Who or what changed the access rights?".
pkgadd calls checkinstall by the user noaccess. checkinstall calls amqiclen and needs read access to the directory tree /var/mqm. If not it returns with 255 and the installation will be aborted.

 amqiclen -x is the recommended way to remove open ressources if there is no process running.
Usage: /opt/mqm/bin/amqiclen {-c | -x} -c = check -x = destroy
[-m <qmgr>] -m = queue manager.
[-p <prefix>] qmgrs directory Prefix (/var/mqm)
[-q] queue manager subpool
[-i] IPCC subpool
[-o] persistent queue manager subpool
[-t] trace control
[-s] subpools lock
[-c] check only
[-F] Force (deleted active segments)
[-v] verbose
[-h] headings
[-d] display remaining resources
Thanks
Gunter
