I am designing a new message flow. I have three queue managers, application 1, MQSeries hub, and application 2. App 1 is sending two types of messages to app 2. Should I send both message types through one transmit queue and one channel or should I send them through their own separate channels? What if I have 10 different message types going through one channel and the channel goes down? I am wondering if only one sender/receiver channel is defined per queue manager or per message type. Any help would be appreciated.

One channel will be fine. Maybe if message type 1 is a 75meg persistent message that can get to the other side whenever and message type 2 are 500 byte non persistent messages that require a reply as soon as possible, then you might want to set up two channels between the boxes. An "express" channel that will only handle the small messages, while the second channel would handle the big guys that might get in the way of the smaller, more "important" ones. But this is an extreme case. Our Hub and Spoke system only has 1 channel pair between the hub and each remote QM, and it works fine.
