Hi MQ Experts,
Environment : MQ On solaris with Qmgr with CCSID 819. Locale :ISO 8859-1
One my clients posting message from Windows server using .net client. The message contains characters from various European languages like ÄäÉéÖöÜüß"""""°€£
Receiving application hosted on UNIX machine connecting to qmgr in client mode to same local and consuming messgae.
While consuming message above European languages are getting converted to special characters.
We have recommended receiving application to convert data using MQGMO_CONVERT options. However, application team is not ready to change code.
We don't have option to change it over channel with CONVERT(YES) as it is local queue only.
I am trying to change CCSID of QMGR from 819 to 1208 followed by restart which failed to work. I am afraid changing CCSID will have impact on other interfaces. Is there any way to tackle this problem? What is CCSID of European languages on Solaris machine.
thanks in advance.. |

What is the code page of the message payload? Typically .NET strings are in one of the Unicode flavours. Is this code page accurately reflected in the CCSID field of the MQMD?

If the sending application is using Unicode or a different code page to the receiving application (which seems likely given the symptoms you describe) then they either need to ask WMQ to convert the payload or do it within their application code or have the .NET people create it in the correct code page. It's not going to automagically fix itself.

If the queue manager is not being asked to perform converstion either by the application specifying the convert option or the convert option on a channel, it really doesn't matter what the queue manager's CCSID is. It'll never refer to it, because it doesn't need to know what it is because it's not converting to it.

Like any applications that are doing the sensible thing and asking the queue manager to perform conversion? I'd say you're right to be afraid.

The 3 options I list above:
- The receiving application sets the convert option
- The receiving application converts the payload within the code
- The sending application creates the message in the correct code page

There's not a single code page that covers all European symbols, except obviously Unicode. For the traditional ASCII code pages, see here
