What is RFH header in MQ messages and its purpose

Question

When I am writing message in MQ queue through JMS, RFH header is also getting added with message as its property.

Property including

• Jms delivery Mode
• JMS Destination
• JMS Timestamp
• Mcd.msd

Can anyone explain me its use and significance?

Answer 1

The RFH header only allow for a single header to exist in a message, and the RFH2 header allow multiples headers to exist in a message.

I'm not going to explain, this site explained it better than I can :
