Oracle Database Administration from Zero to Hero - Using Data Recovery Advisor (Part 2 of 2)

The video tutorial covers the process of detecting and managing database failures using the Data Recovery Advisor. It explains how to list, validate, and repair failures, both manually and automatically. The tutorial also discusses changing the status and priority of failures and provides practical examples of using various commands. The session concludes with a summary of the learning outcomes.

What is the first step when using the Data Recovery Advisor after detecting a failure?

• Run the 'validate database' command

• Run the 'advise failure' command

• Run the 'repair failure' command

• Run the 'list failure' command

Which command is used to list failures with specific status or priority?

• advise failure

• list failure

• repair failure

• validate

What does the 'validate' command check for in a database?

• Logical and physical block corruption

• Missing data files

• User access permissions

• Network connectivity issues

Which option allows RMAN to skip checking missing files during validation?

• No prompt

• Inaccessible

• Exclude FAILURES

• Preview

What does the 'advise failure' command provide?

• A backup of the database

• A summary of database health

• Repair options for failures

• A list of detected failures

What is the preferred method for fixing failures according to the narrator?

• Ignoring minor failures

• Using third-party tools

• Manual fixes

• Automated repair options

What does the 'repair failure' command do by default before starting repairs?

• Generates a report

• Asks for confirmation

• Backs up the database

• Logs out the user

Which command is used to change the status or priority of a failure?

• advise failure

• list failure

• change failure

• validate

What happens if a failure is marked as closed but still exists?

• It is permanently removed

• It causes an error in the system

• It is recreated with a new ID

• It is ignored by the advisor

What is the purpose of the 'Preview' option in the 'repair failure' command?

• To execute repairs immediately

• To validate the database

• To generate a repair script without executing

• To list all failures
