"file %s created before last CREATE CONTROLFILE, cannot recreate"
*Cause: Attempted to use ALTER DATABASE CREATE DATAFILE to recreate a
datafile that existed at the last CREATE CONTROLFILE command.
The information needed to recreate the file was lost with the
control file that existed when the file was added to the database.
*Action: Find a backup of the file, and recover it. Do incomplete recovery
to time before file was originally created.
