Oracle Database Administration from Zero to Hero - Practice - Using Data Recovery Advisor

The video tutorial demonstrates how to use the Data Recovery Advisor to detect and repair data file loss in Oracle databases. It covers simulating data loss, using the advisor to troubleshoot and repair the issue, and implementing the recommended solutions. The tutorial highlights the advisor's efficiency in diagnosing data failures and aiding DBAs in resolving data loss scenarios.

What is the first step in simulating a data file loss?

• Delete the data file of the user stablespace

• Invoke RMAN and log into Ora DB as target

• Validate the database

• Use the Data Recovery Advisor to list the database failure

What should be done if no failure is reported by the Data Recovery Advisor?

• Ignore the error

• Restart the database

• Validate the database to make the advisor detect the error

• Delete the data file again

What does the HMM file contain?

• The backup of the database

• The list of all database users

• The code to restore the lost file

• The error log of the database

How does the Data Recovery Advisor help the DBA?

• By deleting unnecessary files

• By automatically backing up the database

• By quickly reporting the cause of data loss issues and proposing solutions

• By increasing the database speed

What is the final step after implementing the proposed repair?

• Create a new backup

• Log out of Ora DB

• Delete the HMM file

• Shut down SRV one and restore it from its snapshot
