Hi,

I am sending a request to different application and expecting a response back.
I dont want to set anything in the output node so i used destination list in my compute node as
SET OutputLocalEnvironment.Destination.MQ.DestinationData.queueName='bbb';
SET OutputLocalEnvironment.Destination.MQ.DestinationData.queueManagerName='aaaa';
SET OutputLocalEnvironment.Destination.MQ.DestinationData.replytoqueue='yyyy';
SET OutputLocalEnvironment.Destination.MQ.DestinationData.replytoqueuemanagername='xxxx';


OR
should I specify the
OutputRoot.MQMD.ReplyToQ='yyyy'
OutputRoot.MQMD.ReplyToQMgr='xxxx'


Will the recieveing application be able to send the response by taking destinationlist properties or should I set the properties in MQMD Header.

Is it necessary to check the Request tab ( and leave the ReplyToQ and replyToQmgr name blank) of OutputNode and then specify replytoqueue and replytoqueuemanagername
OR just specify directly in the destination list replytoqueue and replytoqueuemanagername

Please kindly let me know if you know how to use the destination list to specify replytoq and replytoqueuemanagername

Thanks for your time

Your local environment is not passed with the MQ message to the other application, the message descriptor MQMD is... so you have to use the last if you want to pass information to the receiving information.

Thanks ...
One more small question
Can I set
SET OutputRoot.MQMD.MsgTyp=MQMT_RESPONSE
to tell that this message is a request.

You can basically put in there whatever you like as long as the other side understands it ! However if you use the predefined values then I must say there is no such thing as MQMT_RESPONSE...

The following values are from "The Application Programming Reference" manual:

MQMT_SYSTEM_FIRST 1 X'00000001'
MQMT_REQUEST 1 X'00000001'
MQMT_REPLY 2 X'00000002'
MQMT_REPORT 4 X'00000004'
MQMT_DATAGRAM 8 X'00000008'
MQMT_MQE_FIELDS_FROM_MQE 112 X'00000070'
MQMT_MQE_FIELDS 113 X'00000071'
MQMT_SYSTEM_LAST 65535 X'0000FFFF'
MQMT_APPL_FIRST 65536 X'00010000'
MQMT_APPL_LAST 999999999 X'3B9AC9FF'

Guess which one to use for a request
