Message sending and receiving
Figure 28 shows the relationships between entities when messages
are transmitted, and shows the flow of control.
Notes:
- There is one MCA per channel, depending on the platform. There may be
one or more channel control functions for a given queue manager.
- The implementation of MCAs and channel control functions is highly platform
dependent; they may be programs or processes or threads, and they may be a
single entity or many comprising several independent or linked parts.
- All components marked with a star can use the MQI.
