Hello,

I was trying to implement a simple alerting mechanism in our environment using MQ event messages. So I created a separate Queue manager act like a HUB which receives the event messages from all other queue managers, and use the programs to format these messages and further send email alerts.

I have a problem in handling the Qmgr stop event messages (MQRQ_Q_MGR_STOPPING), which will only be sent to remote HUB QMGR when the affected QMGR is active again. I understand QMGR doesn't allow any further action when it is ending with immediate option. but I want to handle this stop event message in real time to send the alert. Is there any option to handle this? please advise

Hmmmm. This approach presumes that a qmgr is in a healthy state such that can, in fact, create event messages.

What if channels to/from hub are not running?

You might want to broaden your approach to include the dspmq control command, and the MQSC commands ping qmgr and display qmstatus all

TH HUB queue manager presumably has a channel to the queue manager in question (in order to receive events), so perhaps you can use the status of the channel as an indicator, since the channels are ended before a queue manager ends, so I don't see how a stop queue manager event could be delivered anywhere else as you say.

Cheers,

This does not cover and idle queue manager in perfect working condition...
The best would be to try and connect to the queue manager (PCF with qmstatus call?). If the qmgr is shutdown the call will fail...
