Java MQClient running on Windows.
Connectis to a Windows QM for MQGETs.
Putting application is C on another platform.
When the message arrives from the app running on Tru64, it has a CCSID of 819, and the Java app is happy getting the message.
But if the putting app is run as an MQClient on a HP-UX server connecting to that same Windows QM, the messages are coded with a CCSID of 1051, and the Java app is blowing up on the conversion.
Looking at other posts,
http://www.mqseries.net/phpBB2/viewtopic.php?t=21403&highlight=1051
I see that switching the CCSID of the HP-UX message to 819 will solve the problem.
My question is what is the best way, and are both of these options valid?
#1 -I ask the sending app running on HP-UX to set the MQMD_CCSID to 819 on the MQPUT.
-or-
#2 - In the Quick Beginnings for HP-UX, Chapter 3, Setting the QM CCSID, it says I can use the LANG parameterto change the codeset and CCSID:
| Code: |
export LANG=en_US.iso88591
|
But I am not clear if that can be set on the HP-UX MQClient server. There is no HP-UX QM involved - just an HP-UX MQClient putting to the Windows QM.

This environment variable would be set in the shell that is running the process that is using the MQClient API.
That is, either put it in the .profile for the userid that's running the client app, or in a startup script for the client app.

Jeff, what would you do if this was your app? Would you code the CCSID to 819 prior to the MQPUT? Or would you set the environment variable?

This may not help much.
I would do whatever best preserved the separation of sender and receiver.
That said, there may be other reasons to set the environment variable for the client app - like ensuring that proper character conversion / language set translation happens when interacting with databases.
You've never known fun until you've tracked down a failure of a Web App to properly display Japanese characters extracted from a database (but NOT in the static HTML!) to be caused by a failure to set a language variable in the app server's environment.
Especially when it's someone else who figures it out... but you're in charge of the app server!
Consult your platform folks about the impact of setting or not setting this environment variable. They may insist that it be set all the time anyway.

If I may add another 2c...
Setting the environment variable keeps the source more portable...
Enjoy  |
