Can a single instance of a client application
open multiple queues at the sever through a single MQI channel. |

Interesting question ... I had to think about this one for a moment. The answer should be (must be?) a definite yes. When one connects to a queue manager, a handle to the queue manager is returned. When one then opens a queue, another handle is returned. For multiple opens, a different handle should be returned. These handles provide the context for interaction, not any concept of a queue name or other information. Have you had a bad experience opening the same queue multiple times?
Of course there may be other considerations ... if an application opens a queue for exclusive use, no other application (even the same process) should be able to open it. |

| Actually, I haven't had bad experiences as such... what I was interested in was how to use a single MQI Channel to open multiple queues at the server, in much the same fashion as a single transmission queue/Message Channel can be used to send messages to a number of different queues located in the target queue manager. |

| If I understand what you are asking, it is transparent to you. You'll issue your MQCONN which will get you connected to the server. You'll then issue your MQOPENs against multiple queues and they'll all go through the channel. Is this what you are asking? |
