Listeners
A listener is an IBM® MQ process that listens for connections to the queue manager.
Each listener object in IBM MQ Explorer represents a listener process; however, if you start a listener process from the command line, the listener is not represented by a listener object in IBM MQ Explorer. Therefore, to administer the listener process from IBM MQ Explorer, create the listener object in IBM MQ Explorer. When you start the listener object in IBM MQ Explorer, the listener process starts.
There are different types of listener available in IBM MQ, depending on the transport protocol that the Message Channel Agent (MCA) uses to send and receive messages through the message channels:
- LU6.2
- TCP/IP
- NetBIOS
- SPX

You can initiate new z/OS® listeners
in IBM MQ Explorer, which are displayed in the
Content view, where they can be started and stopped. Only TCP/IP and LU6.2 are
supported for z/OS listeners in IBM MQ Explorer.
For more information, see Listeners in the online IBM MQ product documentation.
