Implementing security changes online in DB/DC and DCCTL environments

You can perform changes to your security definitions online when you use RACF® for security enforcement.

To change RACF security definitions online, update the RACF database. Then issue the RACF command SETROPTS RACLIST(classname) REFRESH.

RACF refreshes the class that corresponds to classname and all classes that share the same POSIT value on their class descriptor table (CDT) entries.
