Dear MQ Gurus!
We have an MQ Cluster with a Gateway, everything works great, but sometimes the WebSphere Application has a problem (it's still in DEV state) and all messages got stock in MQ Manager which is handling it.
If we stop that MQ Manager manually, Gateway will route all traffic to the good MQ Manager and Application is working fine again.
So, can somebody from you, MQ gurus out there give us a hint how can we stop the MQ Manager when WebSphere server is down?
As well, we can trigger this event by let say " if # of Messages in queue > 10 then do something" but we don't know how.
We tested it manually, we disabled "put message" on the queue and Gateway started routing all traffic to the second (good) MQ manager.
But how to do it automatically?
Any help will be appreciated a lot!
thanks

You cant do that automatically. Write a script to check your WebSphere Application. If it is down put disable the queue.

Hi there!
sorry for the late reply, I was out for few days.
Could you be so kind and let me know how to do that?
I know the UNIX portion, aka:
for x in 'ps -aef|grep web|grep -v "grep web" |awk {'print $2'}'
do
if [ $? -eq 0 ]
then
"put disable the queue"
else
"Do nothing"
fi
done
But, I don't know how to handle that "put disable the queue"
Would you mind to give me some hint, please?
Thanks a million!

You'll have to configure the queue manager and the queues to create performance events, and then write a program to recieve and react to those events.
There's an extensive amount of detail about this in the "Monitoring WebSphere MQ" manual.
