Hi All,
I've written a java program (using MQ Java api) to enqueue a message, which contains MQRFH2 header, in mqseries queue. Now, I need to validate this MQRFH2 header.
How can I do that?
thanks,
deepak |

Examine it with RFHUTIL or similar? Feed it to a JMS application and see if it can read it? Feed it to a WMB flow and see if it parses it?
Other methods may be possible.

validate for what???
u might hv added MQRFH2 header in ur msgs for some specific requirement.... e.g. ur target aaplication needs it to process etc... put the msg in application queue
how about executing that requirement now....

Thanks you all for such a prompt reply.
Actually, I dont have access to the target application. So I just want to have some thing at my end to validate the RFH2 header which I have enqueued.
Is there some tool available to validate the RFH2 header?
thanks,
deepak |

as vitor said : put the message on a MQ queue and browse it using RFHUTIL (ih03 support pack)
this will show u the populated MQRFH2 header fields

Remind me again what you know about the byte alignment of the RFH header?
This is a topic for advanced MQ. Otherwise just use JMS which happens to be a java API, or XMS which allows for the same type of interface in a non java world...
Enjoy

To be fair, the only way to know that your code is correct is to know exactly what your code does, and to know exactly what your code should do, and be able to compare the two.

Thanks, everybody for your reply. I installed RFHUTIL tool, which help me out in looking into the REF2 header hence I can validate it visually.
Thanks all for the reply.
thanks,

Hi fjb,
Please correct me if I'm wrong. By byte alignment did you mean about the structure of RFH2 header (fixed portion and variable portion haveing different folders)?
thanks,

No, he means that there are rules about how the RFH2 is arranged and aligned in memory.

I'm sure you meant "the bitstream that is the message data".

Not sure how else that could be interpreted.

Well, it's not exactly "in memory" if it's in a message sitting on a queue...

Point taken; I should have referred to "physical structure".
