Looking to configure something like:
Local queue in A clustered
A: >>>>>>>> B:
>
>
>>>>>>>C:
HA
Put to A becomes available for get in B
If B is down becomes available for get in C
I am brand new at clustering, I have searching and reading for days and have run out of time. When I create the cluster it works in reverse.
ANY help would be appreciated |

| As per your other thread, clustering has nothing to do with high availability. |

Sorry about 2 threads, posted in the wrong area and couldn't find a way to delete it.
That's noit a very constructive comment. Something like :That won't work, or that might work but you need to look for other options would have been more help. |

Well there was a huge hint there that you seem to have missed.
What Jeff is essentially telling you is that MQ Cluster and HA Cluster are 2 completely different things... as well as MQ Cluster and WAS Cluster with JMS Engine (SIBUS) are 2 completely different things...
Have fun reading up...

My bad, should not have used the term "HA". Instead lets call it "Work Load Balancing"
Here is a quote is from IBM regarding the subject. If it sound familiar it's because basically it's what I am trying to do.
“Workload balancing:
When a cluster contains more than one instance of the same queue, workload balancing determines the best queue manager to route
A message to. It takes into consideration:
-the availability of channels, the queue manager and queues
-how to treat a local copy of the queue (CLWLUSEQ in v6).” |

Actually the solution to this was very simple, too bad it took me so long to figure out.
Local queues are created on B & C instead of A. I had it backwards.
Does round robin by default, fiddling with rank and priority settings now.
A great resource was found here which helped me to understand where I was going wrong.
