Hi All,
Can anybody suggest the code to pass correlation ID as header to the message that we push to MQ.
I have code to push the message to MQ but not sure how to add correlation ID as a header to the message before pushing.
Please let me know ASAP. |

In the Request-Reply app design model, the CorrelId field of the Message Descriptor header (MQMD) is 24 bytes, and typically used to correlate a Reply message to the Request message. It is set == to the MessageId of the Request message.
Does this help?

What programming language would you prefer? In your favorite language, how do you set a variable to a value?
COBOL: MOVE INBOUND-MESSAGEID TO OUTBOUND-CORRELID.

Did you try it? What were the results?
Search google for ‘mq CorrelId Java examples’?

May I suggest that you get some training in MQ fundamentals, especially terminology. Header in MQ means one of the many IBM-supplied structures, such as MQMD (Message Descriptor), MQOD (Object Descriptor), MQPMO (Put Message Options), and so on.
CorrelId is a field in the MQMD.
'Push' is not an MQ term. Messages are MQPUT to queues, MQGET from queues. Many development language environments are supported, included MQ Classes for Java, JMS.
