SUBSYSTEM

Specifies the TCP/IP Subsystem (stack) address space that is used by CDC Replication for communications between itself and other instances of CDC Replication, or between itself and Management Console.

It is possible to have more than one TCP/IP Subsystem address space executing concurrently on the same image of z/OS®. This is called running multiple stacks.

name is the name of the z/OS address space in which TCP/IP is executing. If * (asterisk) is specified or defaulted, then the first z/OS address space found in which a TCP/IP stack is executing is used. Since it is unpredictable which of the multiple stacks is found first, it is suggested that you avoid specifying (or defaulting to) * unless there is only one TCP/IP Subsystem address space executing at any time.

This keyword is optional.

Default Setting—* - The first TCP/IP Subsystem address found is used.
