You can delete a class entry from the static class descriptor table by specifying the name of the class to be deleted on the link-edit REPLACE statement. For the deletion to take effect, re-IPL all systems that used the class.

You should be sure that all profiles relating to this class are deleted before deleting the entry from the class descriptor table.

Pay special attention to any unique POSIT values you use. If the class you are deleting has a unique POSIT value, issue a SETROPTS LIST to check what options you are using with the class—for example, CLASSACT, LOGOPTIONS, AUDIT, and RACLIST. Turn off each of the options for the class.

To illustrate: You might have activated your class. You should deactivate the class before re-IPLing your system. If you do not deactivate the class and, at a future date, you create a class with the POSIT value previously used, the class will automatically be active. The same consideration applies to each option controlled by the POSIT value.
