Hi All,
I want explanation on why to use RFH header when we can set Msg type in Message Header(Descriptor)?
What is advantage on using RFH in MQSI flow?
When it should be used?
Waiting for discussion.
Thanks,
Prasanna |

Hi,
I'm using the RFH2-Header.
The Advantage is that you can pass additional information from within the flow or from other external resources (like a cics transaction on OS390) without changing the message body itself.
In my case I need to pass the message through several CicsTxn on OS390 and need information from these transactions in the message flow
for different handling of the message body. |

Hi, We use RFH2 two ways:
1. As a common error header. When exceptions are generated we parse the exceptionlist and store it in the RFH2 header along with the orginal message. This works nicely because the RFH2 is a standard header and can be parsed easily.
2. As a common file adapter header. We have large legacy files that we break up into individual messages to send through WMQI for transformation and routing. We attach the RFH2 and store some of the original file attributes along with reconciliation information needed for audit purposes.
