I am getting this error message when trying to get the message off the queue:..I am reading the messages through JMS.
MQJMS1050: The MQRFH2 header has an incorrect format
I wasn't getting this message when message broker was not involved.
Any suggestions please???
Thanks. |

Don't double post; pick a likely looking section and plump. The moderators can always move it later!

So it works until the broker is involved? How is broker generating the RFH2?

Hi Vitor,
Here I am using a Compute node to generate the RFH2 header
CREATE COMPUTE MODULE FlowABC_AddJMSHeaders
CREATE FUNCTION Main() RETURNS BOOLEAN
BEGIN
-- CALL CopyMessageHeaders();
CALL CopyEntireMessage();
-- If there is no RFH2 header, add one
IF CARDINALITY(OutputRoot.MQRFH2.*[]) = 0 THEN
CREATE NEXTSIBLING OF OutputRoot.MQMD DOMAIN 'MQRFH2';
END IF;
-- Set MQRFH2 struct fields
SET OutputRoot.MQRFH2.(MQRFH2.Field)Version = 2;
SET OutputRoot.MQRFH2.(MQRFH2.Field)Format = 'MQSTR ';
-- Set the JMS destination and reply fields
SET OutputRoot.MQRFH2.jms.Dst = 'queue:///ESB.REQUEST';
SET OutputRoot.MQRFH2.jms.Rto = 'queue:///ESB.REPLY';
SET OutputRoot.MQRFH2.mcd.Msd = 'jms_text';
-- Set MQRFH2 User attributes
SET OutputRoot.MQRFH2.usr = NULL;
RETURN TRUE;
END;
Please let me know whether I am missing something or need to eliminate anything???.
Thanks. |

I think your problem is that you're creating a NEXTSIBLING of MQMD. The first sibling of MQMD is the message body, the RFH2 will be the next and hence it's in the wrong place.
A Trace node will tell the tale.

Um...
I believe that NEXTSIBLING is the correct place for MQRFH2 tree.
http://publib.boulder.ibm.com/infocenter/wmbhelp/v6r0m0/topic/com.ibm.etools.mft.doc/ac12610_.htm
Either the MQMD.Format field is not set to MQFMT_RF_HEADER_2 or the MQRFH2.Format is not properly set to MQFMT_STRING - I see the constant 'MQSTR ', but it's always better to use the constant.
Also, I'm not sure that MQRFH2.Format is an MQRFH2.Field.

Granted, but if you've already done a CopyEntireMessage doesn't MQMD already have a sibling called Body? Or am I being thicker than a whale sandwich?

I'll not make any cracks about your weight, as I've no basis to judge... 
CREATE .. NEXTSIBLING will insert the MQRFH2 as the next sibling. So, afaik, that line of code is actually correct.
But only a Trace knows for sure.

Hi Guys,
Here is the message flows scenario:
FanOut flow: Input queue -> Aggregate Control -> Compute(XSLT transformation) -> Compute node(Add Jms Header, the code what I mentioned above) -> Aggregate request
FanIn flow: Original Msg + Reply from Destination App => Aggregate reply -> Compute (transformation using XSLT) -> MQoutput node(output queue)
The problem is not in the request message flow(FanOut).
The problem is in the reply message after translation and getting off the message from output queue.
Suggestions please |

I see the MQMD.Format = MQRFH2 and MQRFH2.Format = 'MQSTR '.

You seem to have two MQMD and MQRFH2 trees in there.
This might be part of the problem.

Let me be candid.
You are sending a JMS message over MQ. You are not setting any specific values to the RFH2 header.
Why add an RFH header at all? The JMS consumer will not care whether there is an RFH header or not....
Have fun
