Hi, all...
Our Unix (HP-UX) admins just got done changing the mqm UID, and now we can't get the queue manager started (V5.2)...
The strmqm fails with: AMQ6109: An internal MQSeries error has occurred.
In the AMQERR01.LOG, I see:
04/16/02 13:26:51 AMQ6118: An internal MQSeries error has occurred (D)EXPLANATION:An error has been detected, and the MQSeries error recording routine has beencalled.ACTION:Use the standard facilities supplied with your system to record the problemidentifier, and to save the generated output files. Contact your IBM supportcenter. Do not discard these files until the problem has been resolved.-------------------------------------------------------------------------------
04/16/02 13:26:52 AMQ6183: An internal MQSeries error has occurred.EXPLANATION:An error has been detected, and the MQSeries error recording routine has beencalled. The failing process is process 10851.ACTION:Use the standard facilities supplied with your system to record the problemidentifier, and to save the generated output files. Contact your IBM supportcenter. Do not discard these files until the problem has been resolved.-------------------------------------------------------------------------------
The FDC looks like:

Sorry about the format of the FDC log...
Could it be that MQ stores UID-based authorities internally??? Would those UID-based authorities be the ones that setmqaut/dspmqaut work on???
We changed back to the original UID, and I can now start the queue manager, but the Unix admins want a consistent UID for MQ across all of our HP-UX boxes so that if we have to do a fail over (via HP ServiceGuard) we don't have authority conflicts...SO...we do have to change the UID for mqm when I come up with a resolution.
Thoughts, anyone???

Well the issue is making sure that all the permissions/ownership's are changed
when you change th UID of mqm. So if you just issue chown -R /opt/mqm you will
disable the suid bit's
/opt/mqm some files have the suid bit set
/var/mqm some files have the suid bit set

Thanks for the reply, Jeff...
I passed the info on to our admin guys; here's what they told me in response:
They used the HP SAM (like SMITTY) tool to make the change. The process it went through is roughly the following:
- change the olduid to the newuid in the /etc/passwd file
- recursively chown from the olduid to user mqm
In a nutshell, they can't think of any reason why this wouldn't work...
I did do a quick check of authorities/ownerships in /var/mqm and /opt/mqm when we first noticed the problem, but nothing jumped out at me...
Regards,

Did you clear Shared memory after the change to the new UID ????

ipcrm will work.
little script
ipcs | grep mqm | while read type id d3
do
ipcrm -$type $id
done
run the above as mqm
