I pulled it straight from the MQ conference this year. Ian Vanstone (from IBM Hursley) mentioned this in one of his session on "Administering WMQ Qmgr Clusters".
I also found these 3 statements in the Cluster manual:
Every queue manager in a cluster must refer to one or other of the full repositories
in order to gather information about the cluster and so build up its own partial
repository. Choose either of the repositories, because as soon as a new queue
manager is added to the cluster it immediately learns about the other repository as
well. Information about changes to a queue manager is sent directly to two
repositories.
================================================================================
When a queue manager sends out information about itself or requests information
about another queue manager, the information or request is sent to two full
repositories.
================================================================================
Having selected the queue managers to hold full repositories, you need to decide
which queue managers should link to which full repository. The CLUSSDR channel
definition links a queue manager to a full repository from which it finds out about
the other full repositories in the cluster. From then on, the queue manager sends
messages to any two full repositories, but it always tries to use the one to which it
has a CLUSSDR channel definition first.
I hope this helps.

Mike,
You said:
>out of the box MQ will only publish and subscribe cluster object
information to 2 Full Repositories
can you point to where this is documented please.
Thanks
Dave
