I'm using MQ V5.3 and doing some MQ clustering testing.

There are 3 queue managers (QM1, QM2, QM3) in a MQ cluster (CLUSTER1). The QM3 works as a gateway queue manager to the outside world. I've created a cluster queue (C1_Q) on both QM1 and QM2.

There is a queue manager (QM4) outside the CLUSTER1 and we want to send messages to the C1_Q from QM4. Therefore, we've setup a sender/receiver channel from QM4 to the gateway queue manager QM3.

In QM3, we've setup a QM alias as follows :

DEFINE QR(C1_CLUSTER) RNAME(' ') RQMNAME(' ')

In QM4, we setup the remote queue as follows :

DEFINE QR(C1_RQ) RNAME(C1_Q) RQMNAME(C1_CLUSTER)

Then, we use the amqsput command on QM4 to send testing messages, i.e. : amqsput C1_RQ QM4

The result is positive, the testing messages can be sent to the C1_Q on QM1 and QM2 in round robin pattern.

However, I checked that the DEFBIND is set to OPEN on the cluster queue (C1_Q) and the remote queue definition (C1_RQ). So, why the messages are sent in round robin pattern rather than only to a particular queue manager?

Any idea?

Thanks and regards,
