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.
