In this module, you learned how to minimize database downtime during the recovery process. You can achieve this by various methods including starting the database with the missing datafiles or performing parallel recovery.
In addition, you learned how to perform read-only tablespace
recovery and how to reconstruct the damaged or lost control file. If you take the time to plan recovery strategies before a media failure
occurs, you can expedite the recovery process as well as recover damaged or lost files.
Having completed this module, you should be able to:
- List the methods for minimizing database downtime
- Start a database with missing datafiles and perform a recovery
- Describe a parallel recovery
- Reconstruct a lost or corrupted control file
- Recover a read-only tablespace
- Describe recovery issues related to read-only tablespaces
