I am trying to setup a MQ Cluster that has the following config

  1. There are 3 host machines, ubuntuvm-1, ubuntuvm-2 and ubuntuvm-3
  2. ubuntuvm-1 has one Full repository queue manager and one partial repository queue manager. QM_FR1, QM_PR1
  3. ubuntuvm-2 is same as above. QM_FR2, QM_PR2
  4. ubuntuvm-3 has only one partial repository queue manager, QM_PR3

Following are the steps I have taken

  1. I have created cluster receiver channels on each queue manager that point to its own queue manager.
  2. I have created cluster sender channels that point to at least one full repository. I have made sure that the channels are correct, i see the tests pass when I run them through the MQ Explorer.

I get an error when using MQ Explorer, I try to add the QM_FR1 queue manger to cluster (CLUSTER1). Following is the error.

Access not permitted. You are not authorized to perform this operation. (AMQ4036)
Severity: 10 (Warning)
Explanation: The queue manager security mechanism has indicated that the userid associated with this request is not authorized to access the object.

Why am I getting this error and how do I fix this?

Please shout if you want me to provide more details.

This is a common cause in IBM MQ:

A little added to the above link, It seems you are using MQ Explorer on "ubuntuvm-1", I wonder,
1. which user do u use to start MQ Explorer?
2. Does this user in mqm group or have enough authority to add qmgr to a cluster?

This piece of error msg said the user you used does not have right to do Qmgr admins work. To further looking at the issue, please show us some output
$ id username-who-start MQ Explorer
Qmgr Error log.
/var/mqm/qmgrs//errors/*.LOG

Another faster way to isolate the issue, you can simply use Terminal to do the procedure; like,
$ su - mqm
$ mqsc QmgrNAme
ALTER QMGR REPOS(CLUSTER1)
DEFINE CHANNEL(...... etc
There is no qmgr nor server reboot needed. Hope this help.
