I have three queue managers X, Y, Z, all part of a cluster. X & Y are hosting a queue called Q1 in the cluster. Now if any application connecting to Z puts a message in Q1, based on the default cluster workload exit, the message is being round robined.
How do I force the application to send the message to Q1 on X but not Q1 on Y? All the queue managers are using the default attribute "Bind On Open".
Thanks,
Rajesh |

You can specify MQOO_BIND_ON_OPEN option in your MQOPEN call.

So, how does the MQOPEN look like? Let's say I leave my application untouched. So it uses the default open open which is MQOO_BIND_AS_Q_DEF which is "Bind on Open". But "bind" to which queue manager? Where do I specify that queue manager name in the MQOPEN call?
The program will be in COBOL....

I believe you will have to specify the queue manager name in Object Descriptor.
Please take a look at Chapter 5 in Queue Manager Clusters manual.

I have read the manual @ http://as400bks.rochester.ibm.com/iseries/v5r1/ic2924/books/csqzah01.pdf....
In pages 48 thru 50 the document has explained how to force the message to a specific queue manager. This is by setting the ObjectQueueManager field in MQOO. This is all good for MQPUT.
However, my CICS application is using MQPUT1, the statement on page 50 is:
The MQPUT1 call always operates as though MQOO_BIND_NOT_FIXED were in effect, that is, it always invokes the workload management routine.
Any ideas as to how I can avoid this?

You don't need MQOO_BIND_ON_OPEN option ( it's useless with MQPUT1 ).
What you need, like kirani have said, to specify the queue manager name in Object Descriptor.

How do I force the application to send the message to Q1 on X but not Q1 on Y? |
Don't host Q1 on queue manager Y. |

You could use a cluster workload exit(CLWL). You can this exit force the message to be sent to another QMGR.
Be aware that it's quite easy to create a loop.... eg. sending the same message between two or more qmgrs....

Change the CICS program to use MQOPEN,MQPUT,MQCLOSE  Five minutes of work...
Just my $0.02
