Using MPF to handle foreign messages

Using MPFLSTxx you can specify whether you want subsystems to receive foreign messages and DOMs (messages and DOMs from another system). By reducing the number of messages through the SSI, the installation can reduce the amount of CPU utilized for these foreign messages.

Use the following statement and one of its option in MPFLSTxx to specify whether you want subsystems to receive foreign messages and DOMs:

.FORNSSI

Specifies that you want to define whether subsystems should receive foreign messages and DOMs.

The options that you can specify for .FORNSSI are as follows:

*ALL - All subsystems will receive foreign messages and DOMs.
*NONE - No subsystems will receive foreign messages and DOMs.
NOCHANGE - The system should retain the previous FORNSSI statement.
(list of subsystems) - Names of one or more subsystems that are to receive foreign messages and DOMs. Subsystems not in this list do not receive foreign messages and DOMs.
