| If I have a very large message that the application breaks up into several smaller messages and sents in a MQ cluster, how do I ensure that all the small messages reach the same physical queue ignoring load balancing. |

Using bind on open or putting a specified qmgr name in the mqmds.

can you elaborate . I am new to MQ.
I have a java app that breaks up the messages and expects all the messages to go to a certain cluster Q(1 physical location) and the next set of messages to another cluster Q (different physical location) , load balancing should exist between the 2 sets of messages. |

On the MQOpen call, specify the option MQOO_BIND_ON_OPEN.
| Quote: |
| This causes the local queue manager to bind the queue handle to a particular instance of the destination queue when the queue is opened. As a result, all messages put using this handle are sent to the same instance of the destination queue, and by the same route. |

then you will need to close and open the queue between each set. Or, again, write the load balancing yourself and specify the different QMGRs in the MQMD.

How large is this message that you want to break up? (you may be doing it unnecessarily and causing yourself extra work)
