Use the "RESET_CACHE Procedure" instead of this deprecated procedure.
To increase performance, Oracle Application Express caches the results of authorization schemes after they have been evaluated. You can use this procedure to undo caching, requiring each authorization scheme be revalidated when it is next encountered during page show or accept processing. You can use this procedure if you want users to have the ability to change their responsibilities (their authorization profile) within your application.
The following example shows how to use the
RESET_AUTHORIZATIONS procedure to clear the authorization scheme cache.
BEGIN APEX_UTIL.RESET_AUTHORIZATIONS; END;
