Defining partner systems
In order to define a usable link between two partner systems, an MSPLINK, MSLINK, and MSNAME must be defined on both sides. These MSC resources can be defined dynamically by using CREATE MSPLINK, CREATE MSLINK, and CREATE MSNAME commands, or statically by using stage-1 system definition macros MSPLINK, MSLINK, and MSNAME.
A relationship exists between the three MSC resource types MSPLINK, MSLINK, and MSNAME that define the names of connections between systems and the logical names that are used in commands.
