Well, there it is plain as day! You can't mix AUM and MUM in an
instance...even though the undo_management parameters don't have to be
identical ;) I understand the that undo_retention and
undo_suppress_errors don't have to be the same and undo_tablespace
*must* be different, so why not indicate this in the parameter section?
I guess I needed to RTWholeFM.
Thanks for coming across this. This is why the list is great. I don't
know anyone who reads the whole manual and can remember every word. By
combining our eyes and brains, we'll have read it all as a group.
