Hello experts,
When going through mqoutput node properties, I did not find any difference between using replytoq field of request properties and queue of basic properties. can anyone give me clear information apart from the documentation given.

If you set the MQOutput node to ReplyTo queue, it will automatically put the message to the details specified in the MQMD. If it's set to queue, it puts it to the queue specified in the node. If it's set to distribution list, it puts the message to the details set in the distribution list.
I think the documentation lays that out quite clearly.

setting on
MQOutput node = static
MQMD (in ESQL) = dynamic |

MQMD does not have to be set in the ESQL, typically set by the putting application.
You knew that, just underlining it.

mr vitor,
you mean to say that there is no difference.

They're entirely different.

No, I mean (or meant) to say that the node behaves in the 3 modes I described, obtaining the target details from the places I listed.
If you're asking "Is there a difference between using the replyto mode and queue where the queue is the same name?", then you're right - there is no difference. As jbanoop correctly points out, the queue cannot be varied dynamically where replyto can. It depends what you want it to do.
If that's not what you're asking, please rephrase the question!

Thankyou Mr. Vitor.
All this while i have been trying working with this node.
As understood we cannot set the queueName dynamically when Destination mode is queueName, but when it's set to ReplytoQueue we can set queue's dynamically.(setting MQMD).
Thanku ones again.

But don't use ReplyToQueue unless you're sending a REPLY.
Use DestinationList instead.

Mr Jeoff,
We are setting the replytoqueue property dynamically in a
compute node using statement outputroot.mqmd.replytoq=newqname.
but what is the use of replytoq and replytoqmanager fields in the request properties of output node when we are setting these properties dynamically. |

You CAN set the destination queue name dynamically using the DestinationList (as Jeff Mentioned)
eg: OutputLocalEnvironment.Destination.MQ.DestinationData.queueName='';
You can also set the Reply To Queue name dynamically
OutputRoot.MQMD.ReplyToQ='';
both can be set statically as you would already know on the MQOutput node.

Hi rock,
If you set the replyToQ in the Output Node, then the message sent out would be a request, and the receiver who gets that message will know where to reply using the ReplyToQ property in the header....
Regards. |

Mr jbanoop,
I tried working with the code given by you and it is not working and giving an exception that failed to open the queue(I did not specify any queue name in the basic properties of mqoutput node). |

This is specified in depth in the documentation. Try reading it.
But -
If you use replyto the way you are, the node will additionally change the message to reply. If you want to dynamically set a target queue name, use the 3rd MQOutput node property DestinationList rather than queue or replytoq.
