Guide to z/OS utility

Although z/OS® utilities provide functions that are better performed by newer applications, many customers continue to use these programs, and IBM® continues to ship them for compatibility with older supported system levels. This guide lists the tasks for which you can use these utilities, and identifies which utility is especially suited to perform each task.

You can use the DFSMS™ utility programs to perform a variety of tasks, as shown in Table 1. The "Task" column shows tasks that you might want to perform. The "Options" column more specifically defines the tasks. The "Primary Utility" column identifies the utility that is especially suited for the task. The "Secondary Utilities" column identifies other utilities that can be used to perform the task.
