Message channel agents

 

A message channel agent (MCA) is a program that controls the sending and receiving of messages. There is one message channel agent at each end of a channel. One MCA takes messages from the transmission queue and puts them on the communication link. The other MCA receives messages and delivers them onto a queue on the remote queue manager.

A message channel agent is called a caller MCA if it initiated the communication, otherwise it is called a responder MCA. A caller MCA may be associated with a sender, cluster-sender, server (fully qualified), or requester channel. A responder MCA may be associated with any type of message channel, except a cluster sender.
