You might want to run multiple TCP/IP stacks on the same system to provide network isolation for one or more of your applications. For instance, you may have multiple overflow sequential access (OSA) features, each one connecting your system to a different network. You can assign a TCP/IP stack to each feature.
Use the NETWORK DOMAINNAME parameter of SYS1.PARMLIB(BPXPRMxx) to specify the common INET physical file system, C_INET PFS, and then use this file system to set up multiple TCP/IP stacks. This physical file system allows you to configure multiple physical file systems (network sockets) and make them active concurrently.
If you plan to configure the product to use a non-default TCP/IP stack, consult z/OS UNIX System Services Planning, and z/OS Communications Server: IP Configuration Reference, for details.
To configure the product on a system with multiple stacks:
