Oracle Database Administration from Zero to Hero - Practice - Performing Flashback Database

The video tutorial covers managing a flashback database in Oracle. It explains how to enable and verify the flashback database, use it for data recovery, and monitor its performance. The tutorial demonstrates creating and dropping tables, using restore points, and running queries to ensure the database honors retention periods. It concludes with best practices for maintaining sufficient space and monitoring flashback statistics.

What is the purpose of enabling the archive log mode in a database?

• To increase the speed of database transactions

• To enable the flashback database feature

• To reduce the size of the database logs

• To allow the database to be restarted without data loss

Which parameter is crucial for setting the flashback retention target?

• DB_FLASHBACK_RETENTION_TARGET
