Hi,
I upgraded MQ fix pack2 on multiple AIX servers. Some reason only one server giving me trouble.
I stopped all mq apps. None of mq process running (ps -ef|grep mq). But when i try to upgrade fix2 but getting the following error,
You seem to have an MQ queue manager still running.
You must stop all MQ processing, and stop the Queue
Manager(s) by using the endmqm command before trying to
install/update/delete the MQ product.
update: Failed while executing the mqm.txclient.rte.pre_u script.
same error repeated for all components (server,cleint..etc).
I am sure MQ processes stopped on the server.
Smitty options are..
PREVIEW only? (install operation will NOT occur) (first time.. yes) no
COMMIT software updates? no
SAVE replaced files? yes
AUTOMATICALLY install requisite software? yes
EXTEND file systems if space needed? no
VERIFY install and check file sizes? yes
DETAILED output? yes
Process multiple volumes? no
ACCEPT new license agreements? yes
Preview new LICENSE agreements? no
I do not understnad why this server is different from other AIX servers.
Any idea? Any commands to trouble shoot?
Thanks,
Venkat

If you set the environment variable INST_DEBUG=1 before starting smit then the script will be traced and you can see why it thinks there is something running. It will probably be that some process is still attached to MQ shared memory.

I thought uninstall fix1 (roll back to base) shudn't work, if the mq process is running and then tried uninstall fix1...but uninstall went well with out any issue (Now dapmqver - 6.0.0.0).
if i try to install fix1 then the same issue ... very strange.
i set the environmnet INST_DEBUG=1 before smit. Where i can see the trace file?

yes i did ..
ipcs -s |grep mqm
ipcs -m |grep mqm
ipcrm -s <pid>
ipcrm -m <pid>
also checked ipcs -s and ipcs -m for all ....only root has some.
Do i need to care about root shared memory stuff?
An other question...Does a reboot clean up the shared memory issue?
I belive this server rebooted recently and then i tried mq upgrade with out starting any mq/broker processes (auto startup scripts are not ready yet).

Rebooting would certainly clear the process that is still attached to the qmgr.
Another way to try and clear that process would be to try and restart the qmgr. It will tell you that you can't as process x y and z are still attached to the qmgr. Kill those processes (you might have to coordinate with the owner apps), start the qmgr and shut it right down again. Then clear the memory (amqiclen).
After that you should be ready for the upgrade.
Enjoy

I thought same thing and tried couple of attempts ( restart queue manager, stop the qmgr, ps -ef|grep mq ,clean up shared memory..etc).
Bad thing ...i was able to roll back (fix1 to base) and i could't go forward. Very begining it was v6 fix1..just to identify the problem i attempted to roll back to base and it went well with out any issue. If the process is running ...roll back should fail. Looks like upgrade only having this issue.
Tomorrow morning i am planning for the server reboot. I know it's not a good idea ..... but there is no other options before open a ticket with iBM.

Do you have any user-created directories in /var/mqm/qmgrs, i.e. directories which are not the names of qmgrs (or SYSTEM)? I vaguely remember this causing a problem for amqiclen (shared memory & semaphore cleaner) when it is run as part of the install script.

Thank you very much for that info. Upgrade keep failing due to a .txt file uner /var/mqm/qmgrs. Once i remove that .txt then the upgrade went well.
IBM folks,
Please change the error description for this type of problem. On Aix if you have a user defined file or directory under /var/mqm/qmgrs then the upgrade failed with the below error,
You seem to have an MQ queue manager still running.You must stop all MQ processing, and stop the Queue Manager(s) by using the endmqm command before trying to install/update/delete the MQ product.
the above statement is different from the actual root cause(verify mq user data).

Do you have an application running, which uses MQ? You should first stop the application and then stop the QMgr.
If this does not work (or you do not know the appliation), disable the automatic startup of the QMgr and reboot the system.
