Sun Java System Message Queue 4.2 Release Notes

Fixed Ports for C Client Connections

In Message Queue 4.1, C clients, like Java clients, can now connect to a fixed broker port rather than to a port dynamically assigned by the broker's Port Mapper service. Fixed port connections are useful if you're trying to get through a firewall or if you need to bypass the Port Mapper service for some other reason.

To configure a fixed port connection you need to configure both the broker and the C client run time (both ends of the connection). For example, if you want to connect your client via ssljms to port 1756, you would do the following:

Note –

The MQ_SERVICE_PORT_PROPERTY connection property has been backported to Message Queue 3.7 Update 2.
