PLS-00252

reference to the wrong copy of package STANDARD

Action

Make use of on-disk versions of packages when the database is open and fixed (preloaded) versions when the database is closed. Do not attempt to use the wrong set. It should be quite hard to reference the wrong set, except by using SYS.X$ package names explicitly. Also, be sure to 'set serveroutput off' before doing an 'alter database close'.
