Communications

Several facilities enable communication between regions and programs, and collect the following types of message flows:

Inter-Network Management Connection (INMC)

Lets you establish and monitor links between multiple regions.

Advanced Program-to-Program Communication (APPC)

Lets you use the APPC protocol to connect multiple regions.

Inter System Routing (ISR)

Lets you use INMC to provide centralized control at the system level.

Program-to-Program Interface (PPI)

Enables programs to communicate with each other.
