Hai all
I am using MQ Binding mode to connect to the MQ Server.Is there any advantage over connecting to the Server as a Client?How does MQ Series connect in the case of BINDING modes? Can anyone explain?

When using bindings mode in an MQ Java application, when the object methods of put/get (and some others) are invoked, the method eventually calls a JNI library. This native code uses IBM's native libraries to connect to the queue manager. These use efficient inter-process communication to interact with the queue manager via shared memory, semaphores and more. They are more effecient than client access but are only avaialble if the application is co-located on the same system as the queue manager.

Also, one does not always have a choice. Last time I checked linux still only offers the client connection, not server bindings. If this has changed however, I'd definitely be interested to know...

In JMS, does Client support XA transactions. I'm seeing statements to
the affect that MQ/JMS now supports XA - but does that also apply to Client
connections?
