ORA-01672: control file may be missing files or have extra ones

What triggered the Error:

Attempting to create a standby control file, but the control file was either recently created via CREATE CONTROLFILE or an incomplete recovery has been done. Thus the datafiles in the control file and the ones in the data dictionary may not match.

Open the database, then retry the operation.
