Guys,

I have a confusion with the deployment of bar files on Broker with clustered queues(my first time with the mq cluster and broker).
whenever we do a deployment of bar file (using queues)on broker i see an exception saying
"Node failed to open WebSphere MQ queue '<Queue_Name>' owned by queue manager '<QGMR_NAME>': completion code 2; reason code 2085"
in the broker log saying the object not found. But when we do a transaction on the deployed flow the flow works and is able to see the cluster queues(physically not defined on this broker where i deploy the flow).
Any ideas highly appreciated

Thanks
RD

I'll assume the flow is writing to the queue in question as if you were reading the queue it should never work.

No cluster queue is visible on a queue manager where it's not hosted until it's used for the first time & name resolution occurs.

yes it is writing to the queue.

not sure but i am assuming there should be a way for the broker to identify the qmgr it is being hosted on should know that it is part of a cluster.

Bad assumption. No application using a queue manager (and in this context WMB is just an application) can or should determine anything about the queue objects it's using or indeed the queue manager it's connected to.

The point of WMQ is that the application drops a message and WMQ takes care of where it goes. The application doesn't know, control or influence this.
