Hi
I have two boxes :B1 hosting qmgr QMB1, and B2 hosting qmgr QMB2. I have created cluster CLUSTER1 and incorporated these two qmr:s in the cluster.
I then created a local queue on QMB1. I called it QL.Q1. I made it available in cluster CLUSTER1. I did the same thing on QMB2, implying that I have the queue both as local(attached to CLUSTER1) and as cluster, on both machines.
Now I want above two boxes to receive messages from B3 in a round-robin shape.
So on box B3 I allocate qmgr QMB3 and I have it join cluster CLUSTER1.
What happens now is that in the MQ Explorer under QMB3 the queue QL.Q1 occurs TWICE. One occurence with hosting qmgr QMB1 and one occurence with hosting qmgr QMB2. Is this correct?
My next concern is, how to test the Round-Robin? I can do "put test message" on the QMB3occurences, but I have to "manually Round-robin" the put:s, meaning put messages on both the occurenses on QMB3. I also found that in the MQ API exerciser I cannot put anything on QMB3, since no queues are available on QMB3. Obvously the API exerciser does not recognised cluster queues.
Or am I doing something wrong?

You can use the Sample programs amqsput to test the round robin

The 2 instances of the Queue in the Explorer on QM3 is correct. One for each QM that haosts it
Any program that puts to a queue can be used to test, but remember to change the Queue attribute first:
The default Open option is MQOO_BIND_AS_Q_DEF.
The default Queue property is DEFBIND(OPEN).
This means that once you Open a Cluster Queue, all MQPUTs to that queue will go to the same instance if you don't change DEFBIND.
Cheers,
