I think you misunderstand the role of XA or the meaning of "best effort" in this case.
I've used XA and similar "best effort, first commit" systems for years, and am told that ... |

No, this merely means that you think you need to solve this with a single instance and with an exclusive consumer.

Forum: IBM MQ Java / JMS Posted: Wed Sep 22, 2010 1:07 pm Subject: That won't work |
Again, What in the world is the point of having MQ extensions to JMS if not to easily enable MQ custom behavior to a JMS application??

In a non-JMS Java MQ application you just set MQOO_INPUT_EXCLUSIVE=1, MQOO_INPUT_SHARED=0 as open options and it works well. [i.e. The first reader gets the connection, others block.]

Hi,
Within MQSeries are there any client-side calls that can be made to see which app or host+port is connected to a given queue?
If that's not always available directly, can some admin options ... |
