Channel programs

This section looks at the different types of channel programs (MCAs) available for use at the channels.

The names of the MCAs are shown in the following tables.

Table 1. Channel programs for Windows, UNIX and Linux systems

Program name	Direction of connection	Communication
amqrmppa		Any
runmqlsr	Inbound	Any
amqcrs6a	Inbound	LU 6.2
amqcrsta	Inbound	TCP
runmqchl	Outbound	Any
runmqchi	Outbound	Any

runmqlsr (Run IBM MQ listener), runmqchl (Run IBM MQ channel), and runmqchi (Run IBM MQ channel initiator) are control commands that we can enter at the command line.

amqcrsta is invoked for TCP channels on UNIX and Linux systems using inetd, where no listener is started.

amqcrs6a is invoked as a transaction program when using LU6.2
