Hi,
I'm thinking of a set up with the following QMs
Core Tier: Cluser QM1 Cluster QM2 Cluster QM3
Distribute Tier: Distributed DQM1
Cluster QMs have same queue definition of queue Q1. Distributed DQM1 needs to send msgs to Q1 *and* doesn't want to be part of core tier mq cluster.
1. Can I define a remote queue in DQM1 to connect to the cluster ?
2. If yes, how can lock in a specific queue instance in core tier after work load management picks up a queue instance ?
3. I think another design is put DQM1 into core tier cluster, what are the cons and pros comparing these two designs ?
Thanks in advance.

Sky,
Your questions cover all sorts of issues/factors. Here's the quick answers:
1) Yes, but the remote definition doesn't "connect to the cluster". It simply makes a queue that may or may not be a member of the cluster visible to the queue manager that is not part of the cluster.
2) No. It doesn't work that way. Since your queue manager is not a member of the cluster, and you used a traditional remote queue definition to place a message on a queue within the cluster, no workload balancing will occur.
3) You would likely want to put DQM1 in the cluster, because this is the only way you can achieve workload balancing across all instances of Q1. Going back to question 2, yes, you can lock in a specific queue instance. You can use MQOO_BIND_ON_OPEN to lock a specific instance of Q1 for all subsequent MQPUTs, or you can use MQOO_BIND_NOT_FIXED to let workload balancing occur on every MQPUT.
Is there any particular reason you don't want DQM1 in the cluster?
