Hi everyone,
Been trying to work out this issue for some time now, searching every post in this subject here.... and something tells me the solution is so obvious and I'm just missing a little something...
So first the details: wmb 7.0.0.4 on AIX
I have a message in utf-16 coding (CCSID 1202 to be exact) that need to be added with MQRFH2 header, adding usr data.
When trying to put the message in a queue I get the error String too long to convert.
Now CCSID property for MQMD, Properties and the MQRFH2 headers are all set to 1202. Furthermore, the NameValueCCSID is also set to that value.
I will add that the code for adding the MQRFH2 header is generic and so other messages are passed ok, ones with different coding (1208 and 424).
Anyone has a suggestion on what's going on?
Many thanks,
~ Gil |

| I add the MQRFH2 header using a compute node. It's not a C/Java/other program which builds the new message. And as for my knowledge (correct me if I'm wrong) the broker itself recalculates the new buffer length of the message.... |

ugh... I just now realized I posted this question in the wrong forum.... 
If one of the admins could please move it to Message Broker Support.
Thanks and sorry for the trouble...
EDIT by exerk: Done, and it was no trouble. |

Thanks for the reply
Hmmm as you thought, my sysadmin didn't change the borker effective level... So now it's done and... still not working  (But still was an important thing to do) |

If you have been trained on the WMB product, you can open a PMR to request step-by-step assistance. There may still be a bug related to the link I posted above.

yep been working with WMB for several years now... and was afraid you were going to suggest that.
oh well, thanks a lot for the help! |

What is the complete error message (including BIP error number)?
NameValueCCSID must be either 1200, or 1208, (or 13488, or 17584). It shouldn't be 1202. |

You can open PMRs even if you haven't been trained on the WMB product.

You can open them, but IBM is not obliged to service them.
IBM is not required to respond to requests for support from a customer who has not attended the requisite training.

There it is:
| Code: |
| BIP2133E: Source field '0052004600480020' is too long for a target field of length '4' when converting from Unicode to codepage '1202'. |
And I will add that this error doesn't occur if I remove the MQRFH2 header before putting the message.

You're totally right... I mislead you, we're not updating the NameValueCCSID in that flow.... |

"0052004600480020" is HEX and with a hex decoder you get "�R�F�H� ".
That are 8 Bytes (and it is the UTF-16 encoding of the string "RFH "). And that is too long for your target-field.
Because it (the target field) expects 4 Bytes: It expects the UTF-8 encoding (or 8 bit american ASCII).
Luckily the 8 bit ASCII encoding of the CHARACTERS (character sequence) "RFH " is "RFH " (which is "52464820" in HEX).
The encoding only applies to the payload/body not the headers (MQMD, RFH) (and/or any of its values) !?!
The headers (MQMD, RFH, RFH2) always use 8 bit american ASCII ?!
(I am not 100% sure with that)

The declared fields in an MQ header have fixed byte lengths. The character fields in the MQRFH2 header (other than NameValueData) should consist of single-byte characters. Typically, the character set and encoding of the MQMD is defined by the queue manager, and the character set and encoding of each subsequent portion of the message is defined in the preceding header. So, for:MQMD -> MQRFH2 (+ NameValueData) -> message body
the qmgr ccsid (which describes the MQMD character fields) and the MQMD.ccsid (which describes the declared MQRFH2 character fields) must have "single-byte characters for the characters that are valid in queue names".
The NameValueCCSID (which describes the NameValueData) must be 1200, 1208, (or 13488, or 17584), and the MQRFH2.ccsid (which describes the message body) can use any supported code page. |

That is UTF-16 LE with IBM PUA
