| I tried using 'MQReply' and 'MQOutput' node to route messages to Reply-To-Queue. I see messages being routed to appropriate queues but they all have the message type of 'Datagram' instead of 'Reply'. Tried using 'Compute' to explicitly set the message type but of no help. Any idea to have these messages sent as replies will be appreciated. |

I don't think MQReply node will change the MessageType of the message.
What is the code you used in Compute node to set the MessageType which did not work?

Three test that I did so far with message(type is 'Reply') arriving at the 'MQInput'. node.
1) Without any compute node I had the input message (type is 'Reply') routed to the reply-to-q. Message goes to the desired queue, but the type is changed to 'Datagram'. The input message was itself 'Reply' so did not set any of the MQMD properties.
2) Used Compute node to explicitly set the message type as 'Reply' and have the 'MQOutput' node send the message to Reply-To-Q, Again message type is changed to 'Datagram'
SET OutputRoot.MQMD.MsgType = 2;
Also tried,
SET OutputRoot.MQMD.MsgType = MQMT_REPLY;
3) Used 'MQOutput' node with explicit Queue name and it works fine as message is send as 'Reply' but then I have to put a explicit 'MQOutput' nodes for each queue. This solves the problem but does not meet the requirement. |

Did you check your Compute mode option? Was is set to "Message"?

You can use Destination list to populate the queue names and set the Destiantion Mode to "Destination List" in MQOutput Node.

Compute mode option is set as 'Message'. Tried with both 'MQReply' and 'MQOutput' node, the message types are flipped to 'Datagram'.
Haven't explored the Destination List option yet and do not know it fits into my requirement. In my case the Queue Names comes embedded in the MQMD.ReplyToQ.
For now I am using Route-To-Label node to route the message to appropriate labels (Which I have set as the name of the reply-to-Queues itself) and tied them to independent flows which outputs to its own explicit named MQOutput node. The messages indeed are sent as 'MQReply'.
This way, I will be able to route the replies (Type 'Reply') to appropriate reply-to-queue (So far known), but in future if there is need to send messages to new reply-to-queue, I guess, will have to add another small flow for that Queue. |
