#194. The database currently has one control file. You decide that three control files will provide better protection against a single point of failure. To accomplish this, you modify the SPFILE to point to the locations of the three control files. The message "system altered" was received after execution of the statement. You shut down the database and copy the control file to the new names and locations. On startup you receive the error ORA-00205: error in identifying control file. You look in the alert log and determine that you specified the incorrect path for the for control file. Which steps are required to resolve the problem and start the database?
