Hi,
We have two Queue Managers want to join in a cluster (Q1 and Q2 joined to Cluster1). Is it possible to do this with only one full repository (on Q1).
If it can, how to set the cluster sender channel on Q1? Can it just put the Q2 as connection name?
Thanks.
Peter |

You don't need two full repositories for a cluster.
You don't need more than two full repositories for a cluster, either.

So, you have 2 new QMgrs joining an existing cluster?
Do you only have 1 FULL repos in the existing cluster?
Why not just make them both partial repositories?
No need to nominate one of them to FULL...

Let me clarify it.
We used to have a cluster with three queue managers.
Right now, we need to move this cluster to a test environment which only has two queue managers on two seperate servers. We still want to keep all the application functions so that we still use cluster.
In this case the test cluster TEST_CLUSTER is joined in by two queue manager Q1 and Q2. I just don't know how to set up the cluster sender channel.
Thanks for help. |

If you only want one full repository, then you don't need to create a Cluster Sender channel on that QM. Create just a Cluster Receiver, and on each Queue manager that then joins, do the 'normal' Cluster Receiver/Sender pair. MQ will then automatically build the corresponding Sender from the repository.
Cheers,

Why so opposed to 2 full repositories? 2 Fulls is the official # of repositories your cluster should have, whether your cluster has 2000 queue managers, or 2 queue managers.
And yes, it will work with only 1, but why introduce the possability of problems should your Full Repository QM go down and you need to modify cluster definitions on the remaining QM?
Make them both Full and sleep easier. There is almost zero overhead in having both be Full.
