Recovering a Database in NOARCHIVELOG Mode
1. Restore all the data files and control files
2. (optional) if the media failure is not fixed, you need to modify the control file to the new location of data files and redo log files.
SQL> STARTUP MOUNT;
SQL> ALTER DATABASE RENAME FILE '<damaged file, datafile, redo log>' TO '<new location>';
3. SQL> RECOVER DATABASE UNTIL CANCEL Because online redo logs are never backed up, you cannot restore them with the data files and control files. To enable the database to reset the online redo logs, you must first mimic incomplete recovery:
4. SQL> ALTER DATABASE OPEN RESETLOGS;
