Illustrating file systems in single system and sysplex environments

The illustrations in this section show you how the file system structures have changed since the introduction of the shared file system support. These illustrations build upon IBM's long-standing suggestions that you separate the system setup parameters from the file system parameters so that each system in the sysplex has two BPXPRMxx members: a system limits member and a file system member.

In the shared file system environment, that separation of system limit parameters from file system parameters is even more important. Each system will continue to have a system limits BPXPRxx member. As you will see in sections that follow, with shared file system support, you can have a file system BPXPRMxx member for each participating system or you can replace those individual file system BPXPRMxx members with a single file system BPXPRMxx member for all participating systems.
