Hmm.
If the backup were consistent (a cold backup of a database in noarchivelog
mode, or an rman backup while the database is in a mount state) then no
recovery would be required.
One could force recovery, telling it that the controlfile was a backup
controlfile (even if it was not).
But if no archived redo logs (or online redo logs) are being applied, then
what is the point of performing a cancel-based recovery?
