hi all,
This message flow i have outputs MRM messages ..... & i have to include some MQRFH2 headers.

The Format field describes what the data "following" this header is. So, if you set the MQMD Format to be MQFMT_RF_HEADER_2, you are saying that an RFH2 header is next. So, in the Format field of the RFH2, you set the format of the data that follows. If the data is all character, then MQFMT_STRING is the one to use.
Cheers,

Thanks Eddie for the reply.
But the question was not about the MQMD.Format.I'm clear about it.
Question was about MQRFH2.Format values .......
the reason why i ask is ......i'm sending out TDS format data out of compute node and also need to send some RFH2 headers to be used by downstream applications. Initially, I set MQRFH2.Format = 'MQFMT_RF_HEADER_2' then I started seeing below errors :
| Quote: |
AMQ6174: The library /var/mqm/exits//MQHRF2 was not found. The queue manager
will continue without this module.
EXPLANATION:
The dynamically loadable file /var/mqm/exits//MQHRF2 was not found.
ACTION:
Check that the file exists and is either fully qualified or is in the
appropriate directory. |
When I changed MQRFH2.Format to 'MQFMT_STRING' ....... it worked.
This is not the way I expected it to work.... why do I need to set it MQFMT_STRING rather than MQFMT_RF_HEADER_2 ?? Am I missing some basics here ??
pls tell me ... |

The Format field in each header tells you what the format of the CONTENTS of the message described by the header will be.
So, when the message has these sections: MQMD, MQRFH2, BODY, then the Format of the MQMD needs to specify MQRFH2, and the Format of the MQRFH2 needs to specify the Format of the BODY.
Think of it like this: - MQMD Header
- "MQMD Body"
- MQRFH2 Header
- "MQRFH2 Body"
But the bodys are only "implied" - being marked by a blank line in the transport.
