Hi all,
I have 3 queue manager in a cluster environment. QM1:1414 and QM2:1414 are full-repository and QM3:1415 is partial. plus, QM3 is behide a firewall. so I have made a requested to open up firewall on port 1414 from QM3 to QM1. all my cluster queue have defined as notfixed. but when I tested using amqsput on QM3. the message always goes to QM1. Does anyone know what is my problem?
Note: I only have firewall open up 1414 from Q3 to QM1. Do I also need another firewall open up 1414 from Q3 to QM2? and why?
Thanks in Advance for your response |

If the only queue manager in the cluster that QM3 can reach is QM1, then the cluster workload will always send messages only to QM1.
Clustering works by creating automatically defined channels between the source queue manager and the destination queue manager, using information obtained from the repository.
If you can not create a regular channel to the queue manager you wish to talk to, the automatically defined channel will not work either.
So, yes, open up the firewall to allow traffic to the second queue manager, and then you will get workload balancing.
Or set up QM1 to be a gateway queue manager instead of a regular queue manager (this is a logical distinction, not an actual distinction. It basically means put QM1 in the cluster, and host real queues on other queue managers and only references on QM1).

Oh no! I must have done something wrong!
