What do we call the components?

 

1. WebSphere MQ applications can put messages onto a local queue, that is, a queue on the queue manager the application is connected to.

2. A queue manager has a definition for each of its queues. It can also have definitions for queues that are owned by other queue managers. These are called remote queue definitions. WebSphere MQ applications can also put messages targeted at these remote queues.

3. If the messages are destined for a remote queue manager, the local queue manager stores them on a transmission queue until it is ready to send them to the remote queue manager. A transmission queue is a special type of local queue on which messages are stored until they can be successfully transmitted and stored at the remote queue manager.

4. The software that handles the sending and receiving of messages is called the Message Channel Agent (MCA).

5. Messages are transmitted between queue managers on a channel. A channel is a one-way communication link between two queue managers. It can carry messages destined for any number of queues at the remote queue manager.
