Hi,
I have a situation where two MQ servers resist in the DMZ. They are clones of each other. Lets call them "A" and "B".
Now a third node, "C" resides inside the firewall. I needs to communicate with A and B. Since the A and B are load-balanced my approach is
1. To make the A and B Qmgrs a cluster.
2. To keep C outside the cluster and let it communicate with the A+B cluster via a remote queue in C.
Is this the right approach?
Does anyone have an example of how this can be done?
i.e. how to set up the queue:s on A and B to achieve a "true" load-balancing (to have it work iven if one of A-B is out of order)?
Regards Kjell |

In order to have that work C has to be part of the cluster, also You dont use a Q remote definition you use the Queue Name and the Qmanager will contact the cluster for available QManagers with that queue

Thanks, seems to work.
Now, another problem connected to this.
When I setup C and let it join the cluster I can see in MQseries explorer, that the cluster-enabled queues for A-B are available under qmgr C.
I have an ALIAS queue under C and I want to associate that alias with the cluster queue. How to do this? |

Is there any reason for the alias queue ??? you should just specify the name of
the cluster Queue.

The reason is that the sending broker som various reasons wants to PUT to 5 different queues, but we want to concentrate the PUTS to one single queue in the cluster, that's why.
So, can ALIAS queues be shared in a cluster? Any pitfalls here? |

You want to have alias queues that point to the same Cluster Queue ????

Yes
Either I wuld like to allocate 5 Alias queues pointint to a cluster queue
or
Allocate aliases on the repository and make the alias queues available in the cluster.
Is any of these approaches possible to use?

Create the alias on the Cluster Boxes and make them clustered
