I am using Message broker v7.0.0.5 and My Broker environment contain 3 Brokers and 3 Queue managers. All Queue mangers in Single Cluster. I want to create one flow with MQGet Node and Would like to Deploy in All 3 Brokers.
Is MQ Get Node will work in Single cluster ? and Is MQGet node will retrieve the message from same Cluster Input Queue. Pls advice me. |

What do you think it does? Yes or No?
you must have some idea one way or the other.

You know that's out of support don't you?

If this wasn't WMB, but a normal application doing an MQGet deployed to the environment you describe, what would happen?
The same thing will happen with WMB.

Yes. It works fine. The key to get it working with multiple brokers is the ReplytoQMgr field in MQMD. If you share the ReplytoQueue in cluster you lose the control of getting the reply back on the same queue manager from where the request was made. So use the cluster resources but don't share the queue in cluster . (This was one of the interview questions I used to ask before SOAP and REST took over the message oriented middleware)

Thank you for your valuable solution. I tried with ur solution. But In my cluster environment two queue mangers in Full repository and another two Queue mangers in partial repository. But By using Reply to Queue manger concept i am unable to put the message to Partial repository Queue mangers (MB7QMGR3). and I am able to Put message in Full Queue mangers (MB7QMGR1,MB7QMGR2). Pls help me how to reslove this issue.
I used below esql code
SET OutputLocalEnvironment.Destination.MQ.DestinationData.queueManagerName='MB7QMGR1';
SET OutputLocalEnvironment.Destination.MQ.DestinationData.queueName='CLQ2';
--------------------
SET OutputLocalEnvironment.Destination.MQ.DestinationData.queueManagerName='MB7QMGR2';
SET OutputLocalEnvironment.Destination.MQ.DestinationData.queueName='CLQ2';
---------------------
SET OutputLocalEnvironment.Destination.MQ.DestinationData.queueManagerName='MB7QMGR3';
SET OutputLocalEnvironment.Destination.MQ.DestinationData.queueName='CLQ2'; |

If you are trying to put the same message to all three QMGRS in one go then your ESQL is wrong.
If you search this forum (and it is a wonderful source of information you know. Get used to looking there first. It will save you a lot of time)
for

MQ.DestinationData.queueManagerName
|
you will find examples of the correct structures to use for your ESQL.

I used below esql coding based on Reply to Quuemanger
IF InputRoot.XMLNS.MESSAGE.ReplyToQMGR='MB7QMGR1' THEN
SET OutputRoot.XMLNS=InputRoot.XMLNS;
SET OutputLocalEnvironment.Destination.MQ.DestinationData.queueManagerName='MB7QMGR';
SET OutputLocalEnvironment.Destination.MQ.DestinationData.queueName='CLQ2';
PROPAGATE TO TERMINAL 'out';
RETURN FALSE;
ELSEIF InputRoot.XMLNS.MESSAGE.ReplyToQMGR='MB7QMGR2' THEN
SET OutputRoot.XMLNS=InputRoot.XMLNS;
SET OutputLocalEnvironment.Destination.MQ.DestinationData.queueManagerName='QM';
SET OutputLocalEnvironment.Destination.MQ.DestinationData.queueName='CLQ2';
PROPAGATE TO TERMINAL 'out';
RETURN FALSE;
ELSEIF InputRoot.XMLNS.MESSAGE.ReplyToQMGR='MB7QMGR3' THEN
SET OutputRoot.XMLNS=InputRoot.XMLNS;
SET OutputLocalEnvironment.Destination.MQ.DestinationData.queueManagerName='QM1';
SET OutputLocalEnvironment.Destination.MQ.DestinationData.queueName='CLQ2';
PROPAGATE TO TERMINAL 'out';
RETURN FALSE;
ELSE
RETURN FALSE;
END IF |

Did that work?
Why are you using the XMLNS domain rather than XMLNSC?

It is working for MB7QMGR1 and MB7QMGR2 but it is not working for MB7QMGR3. The message is not going to CLQ2 Queue of MB7QMGR3. Because MB7QMGR1 and MB7QMGR2 is in full repository and MB7QMGR3 is in partial repository. How can i send xml message to MB7QMGR3.
for Project need I used xmlns |

Interesting assumption there. How do you know the reason?
btw, a queue manager is not in a full repository or in a partial repository. A queue manager is in a cluster. It contains/hosts a full or a partial repository. |

There is nothing different with an MQGet node from any other MQ application reading from a queue.
The rules for what kinds of queues can be read from are the same.
What are those rules? Have you looked at the knowledge center to find out?
Your thread title and your first post talk about MQGet, but your code and some of your other statements talk about MQPut.
The rules for MQOutput node are the same as for any other MQ application writing to a queue.
What are those rules? Have you looked at the knowledge center to find out?
How does a cluster decide where to move messages? How do you indicate to the cluster that a given message should be sent via the cluster, rather than via some other means?
How are you building your output destinations? Does that match the way that a cluster decides where to move messages?
