Folks,
After upgrading MQ to version 7 on our AIX environments, I tried configuring the new feature of HA between 2 servers. After configuring the NFS and follow the steps giving, there is a step where you need to copy the configuration of .ini file. The step uses the command addmqinf. This step was failing b/c it was expecting a uid different than the current one. After digging into this more , we realized that both mqm uid on each server are different , same case for the mqm group. So , I didn't change the uid and went ahead and created a new user id and group , also created a new queue manager for testing. Made sure the new userid and groupid are the same on both server, as soon as I get to the addmqinf step on the second node , I get the same problem:
AMQ6242 Incorrect ownership for "/ / //QueueManger" . Current(444) Expected(989)
so seems like by default "addmqinf" looks or uses mqm id. Anyone who had seen this issue before or if you have any advice on how this can be resolved , please advice.
Thanks

They are different ,, mqm on first node has a uid value of (989) while on the second node it is (999). When I created a new user and called it mqmtmp and gave it the uid of (444) on both machines , I got the error listed in the first post. So to answer your question , they are different.

well they need to be the same as the numeric values are stored and not the userid/group name itself.

And to reinforce that, the example in the manual for creating a multi-instance queue manager (albeit on Linux) states:
| Quote: |
SERVER 1 - Check what uid and gid /etc/passwd displays for mqm, for example, mqm:x:501:100:MQ User:/var/mqm:/bin/bash
SERVER 2 - Match the uid and gid for mqm in /etc/passwd and reboot if you have had to change the values |

Here is what I have done , and it fixed my issue ...
1. I changed both uid and gid from smitty for the mqm user and mqm group.
2. Then you still have change the gid manually in the /etc/passwd.
3. After that change , all mqm user reference became "8" and all mqm group reference became "14" . Referring to the old uid and gid.
4. I then ran the following commands
find / -user 8 -print | xargs chown mqm
find / -group 14 -print | xargs chgrp mqm
5. Just in case , I ran
ipcs | grep mqm | while read type id d3Â
doÂ
ipcrm -$type $idÂ
doneÂ
run the above as mqmÂ
to clear the memory

IMHO the OP is talking about multi-instance queue managers.
Check out the "What's New" section of the WMQv7 InfoCentre

That clears up a lot. Actually helps me with another design problem I am working on.
Thanks! |
