Hi,

I'm developping a WMQ application on Windows XP and Linux RHEL4. Application Server is C++, Application Clients are C# and C++. The two clients do exactly the same thing (sending a request to a shared queue - the queue is processed by the server and replies are sent to clients' TEMPDYN reply queues). WMQ Server and WMQ base broker are running on Linux RHEL4.

Result :

The two application clients (C++ and C#) are putting correctly their messages on the request queue. Server is eating messages. But Server's responses remain on SYSTEM.BROKER.DEFAULT.STREAM.

Questions :

1) Why broker does not eat publish messages ?
2) How could I find it out broker specific error messages ?
3) If I browse queue messages I find out that CCSIDs on messages are changed to 819 even if I put 1208 or MQCCSI_Q_MGR on messages ; even all (client, server, queue manager) have 1208 as CCSID setting value ?

Thanks in advance for any help.

Following lines is information that could help understand the problem.

===============================================
Locale setting on WMQ Server (Linux) :

LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"

LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

Note that on client side (Windows), MQCCSID is assigned 1208.

ALTER QMGR DEADQ(SYSTEM.DEAD.LETTER.QUEUE)
ALTER QMGR CCSID (1208)

var_message.setEncoding(MQENC_NATIVE);
