Activating the user-defined resource classes

Once you have installed the new classes in your system, it is necessary to activate them in RACF before they can be used. This has to be done by a user with system-SPECIAL authority, who enters the following commands under TSO:
SETROPTS CLASSACT($FILEREC)
SETROPTS GENERIC($FILEREC) 
To improve the performance of QUERY SECURITY, you should load the new resource profiles into virtual storage by using the RACLIST option. The RACLIST option is required if you are using the group class, because the connection between the group class and the entity class is resolved by RACLIST:
SETROPTS RACLIST($FILEREC) 
You need to issue the SETROPTS commands for the entity class $FILEREC, because the group class $GILEREC has the same POSIT number.
