Hi guys,
I am working on mb6.0 with platform as windowsXP SP2. I am working on the following flow (1st flow):
MQInput(INPUT_Q)->Trace1->Compute1->MQOutput1(Q1)->MQGet(Q2)->Trace2->Compute2->MQOutput2(OUTPUT_Q)
The 2nd flow is the following:
MQInput(Q1)->Compute1->HTTPRequest->Compute2->MQOutput(Q2)
(The 2nd flow gets the)
The trouble is the following:
At first occasion (all the queues are empty) I put a test message into the INPUT_Q with correct MQMD and the 2nd flow put
the response message into Q2 successfully but the MQGet node of the 1st flow can't found it (propagated the input into the
'no message' terminal).
At second occasion (there is a message in the Q2 of the previous processing) I put the previous test message again into
the INPUT_Q and the MQGet node of the 1st flow get the previous test message from the Q2 so the flow ending with success
(the response message in the OUTPUT_Q).
Compute nodes aren't modify the MQMD.
The settings of the MQGet node are the following:
Message Domain = "MRM"
Message Type = "Envelope"
Message Format = "XML1"
Transaction Mode = "Automatic"
Generate Mode = "Message"
Copy Message = "Copy Headers"
Copy Local Environment = "Copy Entire LocalEnvironment"
Wait Interval(ms) = "3000"
Minimum message buffer size(KB) = "4"
Validate = "None"
Input MQMD Location = ""
Input MQ Parameters Location = ""
Get by Correlation ID = NO
Get by Message ID = NO
Use complete input MQMD = NO
Output Data Location = ""
Result Data Location = ""
Output MQ Paremeters Location = ""
Warning Data Location = ""
Parse Timing = "On Demand"
Use MQRFH2C Compact Parser for MQRFH2 Domain = NO
Use XMLNSC Compact Parser for XMLNS Domain = NO
Mixed Content Retain Mode = "None"
Comments Retain Mode = "None"
Processing Instructions Retain Mode = "None"
I tried to increase the Wait Interval to 30000ms without success.
I don't know what to do 
Can anybody help me please?

Did you set transaction mode on MQOutput1 to ensure that it put the message outside the unit of work?

After having done what Jeff said...
Did you set the MQMD.CorrelId on the MQMD being passed to the MQGET node so that it only picks up the right message. Did you set the checkmark in the node's properties for get by correlId ?

The transaction mode is 'Yes' on MQOutput1.

The transaction mode is 'Yes' on MQOutput1. |
So it's inside the unit of work then? As jefflowrey points out, this isn't going to work.

Yes, I tried also with and without 'get by correlId' (Get by Correlation ID = NO / YES) but the working is the same: the MQGet can only get the message of the previous processing from the Q2.

Thanks for everybody! The TRANSACTION MODE is the solution for this topic.
