I have upgraded only standalone instances, but have never tried the dataguard db's. -- Thanks & Regards Nilesh Oracle DBA (sqlplus "/as sysdba" is my world) "As our circle of knowledge expands, so does the circumference of darkness surrounding it."--Einstein "All men die, few men ever truly live" -- Braveheart "You can get help from teachers, but you are going to have to learn a lot by yourself, sitting alone in a room." --Dr. Seuss "Know me for what I do and for not what I am.
