Hi All,
In the present scenario, we have 2 wmq 7.0 cluster environment running in AIX environment.
ClusterA - QMA, QMB, QMC and GTWA - Gateway Qmgr.
Cluster queue - ESB.CLUSTERA.REQUEST
This cluster queue is presently visible to all clusterA queue managers.
ClusterB - QM1, QM2, QM3 and GTWB- Gateway Qmgr.
The requirement is that ClusterB want to access ClusterA queue - ESB.CLUSTERA.REQUEST from WMQ ClusterB environment.
Can anyone please suggest how do ClusterA queue (ESB.CLUSTERA.REQUEST) visible/access from ClusterB WMQ environment.
Thanks in Advance.

If you are looking at keeping the 2 clusters as separate entities, look at having name resolution work like when using the gateway to send messages to the cluster with a provenance from outside the cluster...
Same principle.
Have fun

I'm not sure why you need two gateway queue managers while one is enough for your requirement.

High Availability. You can have a planned or unplanned outage of one Gateway QM without losing the ability for the 2 clusters to communicate.

Agree to the above. If you want to have the two clusters as separate entities, having 2 gateways make sense. 
However, the poster's requirement seems to be different. If i understand correct from the initial post - just send messages from one cluster to another using gateways. For that, i doubt why the second one is needed.
Peter,
The poster has mentioned that both gateways are in different clusters. Effectively, there is only one gateway in each cluster, which doesn't appear to be for load balancing or high availability here. Just my thoughts.
Thanks. |

yes...two wmq cluster has been design and setup as seperate entities.....cluster A gateway and other message broker queue manager process different services than cluster B.
The new requirement comes to access one existing mq based service hosted on clusterA and this service want to access from cluster B.
Both the cluster environment hosted in different network segment and there is no firewall open between these two clusters.
Both the cluster gateway and broker queue managers environments are running their own separate high availability.....presently there is no communication between two cluster environments.....
The requirement is cluster B gateway queue manager can put the messages in cluster A queue managers cluster queue mentioned as below and message need to be evenly distribute between clusterA QMA, QMB and QMC queue managers....
How to put the messages from clusterA gateway qmgr to clusterB Qma, qmb and qmc cluster queue - esb.clustera.request queue.
Hope you understand the requirement.....
How to configure this setup.....
Thanks....uditar |

Easy ... set up each gateway with the clustered aliases allowing p2p between the gateways... + a generic cluster alias...
