First of all: Thanks for all the other replies to my threads, they really helped alot!
The Question:
I wonder if there it´s possible to set some parameter in the header of the MQ request message which can be used to identify one or more response messages?
Or even better, can I use the output of the request to identify one or more response messages?
I have tried setting the MsgId parameter but it is always increased by one for every message processed by the MQ server.
If you can use the built-in request/response mechanism, you don´t have to worry about that. But - if I remember correctly, you can use the correlationID to map a request to a response.
Let me know if it work or not, I have a sample package laying around somewhere… just gonna find it
I tried to use this mechanism but I didn’t have the result that i wanted to have, so if you find your sample package please send it to me
it’ll help me a lot
In what way didn´t it work as expected?
The request/response does not require you do set any specific fields, other than perhaps the Encoding so you can interpret what´s returned.
If you are not using the request/response feature, the msgID and corrID are used to map a response to a particilar request.
Request
Set the msgID in the MQMD header tab (or leave it, it´s automatically generated if not set) and make sure it´s defined as an output field as well.
Response
Set the msgID from the request as the corrID in the MQMD header section. This makes the service only retrieve a message containing that particular corrID.
