When one or more of the systems in your global resource serialization complex runs TSO/E, you must decide whether or not to treat SYS1.UADS and SYS1.BRODCAST as global resources and how to handle user data sets. If your installation uses the RACF® database in place of SYS1.UADS, see RACF.

If your installation runs ISPF, see the considerations identified under ISPF or ISPF/PDF. How you handle user data sets is especially critical in a JES2 environment.
