Using MQSeries 5.3 on Windows machines:

I have an application that uses a client connection to access MQSeries. There are two different parts to this application. One part uses the C++ interface, and connects by setting channel name, connection name, transport type and heartbeat interval in an ImqChannel object, then uses setConnectionReference to attach the ImqChannel to ImqQueueManager, and then ImqQueueManager connects just fine. That part works great, whether the server is remote or whether it is the same box as the client.

The other part uses MQCONNX. It initializes an MQCD structure with the "client connection channel" defaults, then sets channel name, connection name and short connection name. It then calls MQCONNX with this structure as a parameter. If the client and server are on the same box, everything is fine. But if the client is on a different box than the server, the connection fails with code 2058 - bad queue manager name.

The thing that puzzles me most is that I examined the contents of the underlying MQCD structure in the ImqChannel of the one that works right, it is identical to the contents of the one that doesn't work! And this is the same remote queue manager I'm trying to access from the same client machine, so it can't be a problem with the connection itself.

Anyone have any ideas?
