Refreshing in-storage generic profiles

You might want to use GENERIC REFRESH after changing a generic profile that protects a specific data set. However, extensive use of GENERIC REFRESH can adversely affect system performance.

You can refresh in-storage generic profiles by specifying both the GENERIC and REFRESH operands on the SETROPTS command. When you specify both GENERIC and REFRESH, you also specify one or more classes for which you want RACF® to refresh in-storage generic profiles. This causes all the in-storage generic profiles within the specified general resource class (except those in the global access checking table) to be replaced with new copies from the RACF database. The following example shows how to refresh in-storage generic profiles for the DATASET and TERMINAL classes.

SETROPTS  GENERIC(DATASET  TERMINAL)  REFRESH

You must issue this command each time you want RACF to perform the refresh process.

If you specify GENERIC(*), RACF refreshes profile lists for the DATASET class and all active classes in the class descriptor table except group resource classes (such as GTERMINL and GDASDVOL).
