Hi,
I added two brokers as cloned brokers fro pub/sub .When these brokers are up and running, the published message is going onto subscription queue, when the first broker is not available , the message is not published at all.I deployed the message flow on both brokers.
can any one explain abouth the behaviour of cloned broker in pub/sub environment? |

Hi,
I have brokers in a cluster, mqbroker_01 and mqbroker_02 (each has a qm with the same name). When I try to issue the mqsichangeproperties to clone the subs onto each broker, it doesn't work. Here's what I do:
Against broker1:
mqsichangeproperties mqbroker_01 -e own_exec_group -o DynamicSubscriptionEngine -n clonedPubSubBrokerList -v \"mqbroker_02,mqbroker_02\"
Against broker2:
mqsichangeproperties mqbroker_02 -e own_exec_group -o DynamicSubscriptionEngine -n clonedPubSubBrokerList -v \"mqbroker_01,mqbroker_01\"
...where own_exec_group is the exec group with the 1 beside it when I 'ps -ef | grep DataFlowEngine'.
However, when I mqsibrowse the subs on mqbroker_02, I do not see any of the subs on mqbroker_01. (I've already setup subs on mqbroker_01).
Any ideas as to why subs don't work, or get cloned on mqbroker_02? 
Thanks!

Fixed. Made sure that each broker user is on each broker node and in the 'mqm' group. Also, all system default sender and receiver channels should have mcauser as empty.
