Oracle Database Administration from Zero to Hero - Performing Recovery Part I - Performing Full Recovery

This video tutorial covers the process of performing full database recovery using RMAN. It explains how to identify when recovery is needed, validate backup files, and execute recovery procedures for both whole databases and user tablespaces. The tutorial also discusses the differences between complete and incomplete recovery, and the importance of archive log mode for effective recovery.

What is the primary goal of having a backup plan for a database?

• To increase database performance

• To retrieve lost or corrupted data

• To reduce storage costs

• To enhance user interface

Which command is used to identify missing data files in a database?

• Validate

• Recover

• Backup

• Restore

What does the Restore Preview option do?

• Restores the data files

• Checks which backup files are needed

• Validates the integrity of backup files

• Deletes unnecessary backup files

How does the Validate Header option differ from the Preview option?

• It checks the physical presence of backup files

• It deletes corrupted files

• It compresses the backup files

• It restores the data files

What is the purpose of the validate command in the context of backup files?

• To restore the database

• To check for corrupted blocks

• To delete old backups

• To compress backup files

In no archive log mode, what is required to perform a recovery?

• Online redo log files

• Archive redo log files

• Cold consistent database backup

• Incremental backups

Why is the reset logs option used when opening a database after recovery in no archive log mode?

• To reset the online redo log files

• To apply incremental backups

• To compress the database

• To enhance performance

What is a key advantage of running a database in archive log mode?

• Improved user interface

• Ability to perform complete recovery

• Reduced storage requirements

• Faster data retrieval

What command is used to specify a new location for data files during recovery?

• Validate header

• Restore database

• Switch data file

• Set new name

In archive log mode, what is the benefit of using incremental backups?

• They eliminate the need for redo logs

• They reduce the need for validation

• They are faster to recover from

• They improve database performance
