Hi,
We are pushing message into MQ in RFH2 format. In RFH2 header, if the format is set to MQHRF2 only UTF 8 messages are successfully put into the queue. For non UTF 8 message fails with RC 2334. If the RFH2 header format is set to MQRFH2 then both UTF 8 & non UTF 8 are sucessful.
Could any one let me know the difference between the RFH2 format - MQRFH2 & MQHRF2. |

| I am using IBM Websphere Datastage TX v8 (formerly know as mercator) to post messages into the queue. |

Check up the constants in MQC.MQFMT* You should find a value for the RFH header.
As to what the code set that works for the message content... you need to read up on MQ Header. The MQ headers are chained starting with the MQMD.
Each header contains the CCSID for the next portion of the message.
Note that for the usr folder on the RFH header only a select number of CCSIDs are valid and 1208 or UTF-8 is one of them.
The RFH header has 2 CCSID fields. The first one indicates the CCSID of the next portion of the message. It has also a field for the format of the next portion it could be text (MQC.MQFMT_STRING). The second CCSID field describes the code set for the usr folder on the RFH header.
Read up on the programing reference and manual and understand the implications of format and CCSID 
Enjoy

I remember that I noticed this MQHRF2 during MQSI NEON implementation days, and I was told that this is how it is spelled possibly by mistake, but it was not rectified till long time.
May be now its rectified MQRFH2, and the old MQHRF2 is still supported for backward compatabilty only. But shouldn't be any difference between the two. |

MQHRF2 is the format string.
there is no such string as MQRFH2
the eyecatcher of the RFH2 header is RFH, and the version number is 2 |
