Using the file system on z/OS

This is part of the larger task of customizing your z/OS environment.

If you have more than one MVS™ image, consider how you will use the file system. You can share files in a file system across different members of a sysplex. The file system is mounted on one MVS image and requests to the file are routed to the owning system using XCF from systems which do not have it mounted.

Moving a broker, User Name Server, or Configuration Manager from one image to another is straightforward and the files for each component can be shared.

However, there is a performance overhead when using files shared between images in a file system because the data flows through the Coupling Facility (this is true for trace and other diagnostic data).
