Activating the RACF subsystem

To activate the RACF® subsystem, you must do the following:
  • Update the IEFSSNxx member of SYS1.PARMLIB
  • Assign a RACF user ID to the RACF subsystem
  • Review the RACF PROC provided in SYS1.PROCLIB

    The RACF remote sharing facility requires a SYSLBC card to access the broadcast data set. When the ADDUSER or ALTUSER command adds or modifies a TSO segment, the broadcast data set is updated.

Figure 1 shows the relationship between the IEASYSxx member of SYS1.PARMLIB and the IEFSSNxx member in establishing:
  • The name of the RACF subsystem, and
  • The name of the RACF procedure in SYS1.PROCLIB that is executed when the MVS START command is issued
The name of the subsystem specified in the IEFSSNxx member and the name of the RACF procedure must be identical.
