Steps for changing a dynamic class to disallow generic profiles

Before you begin:

Determine if the dynamic class that you want to change to GENERIC(DISALLOWED) shares a POSIT value with other classes. If so, determine if the other classes sharing the POSIT value also have GENERIC(DISALLOWED). (See Rules about disallowing generics when sharing a POSIT value.)
Do not perform these steps if other classes sharing the POSIT value have GENERIC(ALLOWED) and you do not want to change those classes. Instead, first change this class to a unique POSIT value or to a POSIT value shared with classes that have GENERIC(DISALLOWED).

Perform the following steps to change an existing dynamic class called HORSES8 from GENERIC(ALLOWED) to GENERIC(DISALLOWED).

Delete all generic profiles in the HORSES8 class. To do this:
1. Execute the SEARCH command to create a CLIST containing a command to delete each generic profile in the class.
```
SEARCH CLASS(HORSES8) GENERIC CLIST('RDELETE HORSES8 ')
```
2. Execute the CLIST.
```
EXEC EXEC.RACF.CLIST LIST
```
3. Verify that no generic profiles remain in the class.
```
SEARCH CLASS(HORSES8) GENERIC
```
______________________________________________________________________
If the class shares a POSIT value, repeat Step 1 for each class sharing the POSIT value.
______________________________________________________________________
Deactivate generic processing for the HORSES8 class.
```
SETROPTS NOGENERIC(HORSES8) NOGENCMD(HORSES8)
```
If your class shares a POSIT value with other active classes, this command deactivates generic processing for those classes as well.
______________________________________________________________________
Alter the HORSES8 class to prevent generic profiles.
```
RALTER CDT HORSES8 CDTINFO(GENERIC(DISALLOWED))
```
______________________________________________________________________
If the class shares a POSIT value, repeat Step 4 for each class sharing the POSIT value.
______________________________________________________________________
Refresh the in-storage profiles for the CDT class.
```
SETROPTS RACLIST(CDT) REFRESH
```
______________________________________________________________________

When you finish, you have changed an existing dynamic class, and all classes sharing its POSIT value, from GENERIC(ALLOWED) to GENERIC(DISALLOWED). You have also deleted all generic profiles from all classes sharing the POSIT value.
