To run IRRDPI00 from the RACF® parameter library, do the following:

1. If you already have a RACF parameter library member set up to run automatically when the RACF subsystem initializes, determine which member it is. Otherwise, create a new IRROPTxx member and set it up to run automatically when the RACF subsystem initializes. See The RACF parameter library for information.
2. Add the following commands to the beginning of the IRROPTxx member, ahead of any TARGET commands or any other RACF commands that affect profile segments other than the base segment:

   ALLOCATE FILE(SYSUT1) DATASET('SYS1.SAMPLIB(IRRDPSDS)') SHR
   IRRDPI00 UPDATE
   FREE     FILE(SYSUT1)

3. Make sure that IRRDPI00 is in the TSO/E APF-authorized command table. See TSO/E authorization of the IRRDPI00 command for more information.
4. If you want to test your changes, you can execute the commands in the IRROPTxx parameter library member by issuing the SET command (for example, #SET INCLUDE(xx)). Or, you can restart the RACF subsystem to execute them. An IPL will also execute them, but is usually not desirable.
5. If you previously ran IRRDPI00 from a started procedure such as IRRDPTAB, you should remove the started procedure. The removal should include:
   • Removing the started procedure from SYS1.PROCLIB
   • Removing the COM='START IRRDPTAB' statement from the appropriate COMMNDxx member
   • Removing an entry specifically for the IRRDPTAB started procedure in the started procedures table (ICHRIN03) or the STARTED class, if you set one up
