I do not understand how to access the Queuemanager structure if I haven't created a new instance of QMQueueManager.
This should work. I am using MQ Series client 5.3 and are connecting to an IBM OS/390. The error you got seems to be related to Channel, port or hostname.
If you would have an authorization problem ...
