RACF® provides a general purpose exit, IRREVX01, that can be modified by installations to receive control when the following RACF TSO commands are issued.

RACF does not invoke the IRREVX01 exit for the BLKUPD, RVARY, RACDCERT, RACMAP, RACLINK and RACPRIV commands or for true RACF operator commands such as RESTART, TARGET, and SIGNOFF.

Your location might use installation-written exit routines to take additional security actions during RACF command processing, and these actions can affect the results you get when you issue a RACF command. For example, your location could use the ICHPWX01 preprocessing exit to install its own routine to examine a new password and new change interval.

For a complete description of RACF installation exits, see z/OS Security Server RACF System Programmer's Guide.
