I need to shut down a queue manager. It will be deleted in three months or so. During the time when it is quiesced but still exists, I need to ensure that the queue manager cannot be restarted with the strmqm command. However, I also need to ensure that the queue manager can be restored to a "startable" state very quickly.
How do I disable the queue manager in such a way so that it can be reenabled quickly?
My first thought was to rename the qm.ini file. That does stop the queue manager from restarting. After restoring the name of qm.ini file, I can restart the queue manager. But, when I then tried to delete the queue manager, it was not clean. (I had to remove qmgrs/<qmgr> directory manually, and I has to remove the qmgr reference in mqs.ini.) That made me nervous.
Ideas? |

Comment out its entries in mqs.ini to make it 'invisible'. The strmqm command parses that file and will return AMQ8118: WebSphere MQ queue manager does not exist. - on V6.0 at least!
EDIT: Red letter day! For once I was quicker on the draw than my venerable master! Perhaps the 'venerable' aspect is beginning to tell on him

How about a chmod of the /var/mqm/qmgr/<name> file system or part thereof so that the mqm user id no long has access? Or just the ini file?
I suppose it depends on if you want the queue manager not to start, or shout "Arrgh!!!!" & pitch forward into the dirt a few seconds after the strmqm is issued.

Ooooh, this should be fun!
Comment out the stanza(s) in the mqs.ini file for the qmgr. Although I've not tried this, I'd expect to receive a qmgr not found rc.

Ah, exerk, you are as venerated as they come, in my book. You and bruce2359 are correct: The queue manager is not found after commenting its entries in mqs.ini. After restoring the entries, the queue manager restarted without error. I was able to delete it, too. Excellent solution!
I think we will pass on the dirt eating thing, Vitor.  |

Any solution that works for you works for me.
I just enjoy being cruel to software. Since exerk joined that union....
