OCP Backup & Recovery

Question 1

What is the primary purpose of Oracle RMAN (Recovery Manager)?

Accepted Answer

To perform backup and recovery tasks

Answer

Oracle Recovery Manager (RMAN) is a powerful command-line utility and framework specifically designed for backing up, restoring, and recovering Oracle databases. It simplifies and automates these critical tasks, ensuring data availability and integrity in case of failures. RMAN manages backup sets, image copies, and recovery catalogs efficiently.

Question 2

What is an Oracle database archive log used for?

Accepted Answer

To store changes made to the database

Answer

Oracle database archive logs (also known as redo log files) store a historical record of all changes made to the database. These logs are crucial for database recovery, allowing the database to be restored to a specific point in time by reapplying transactions. They are essential for point-in-time recovery and maintaining data integrity after a media failure.

Question 3

Which backup strategy provides the fastest recovery time?

Accepted Answer

Full backup with incremental backups

Answer

A full backup combined with incremental backups generally provides the fastest recovery time. The full backup serves as a complete baseline, and subsequent incremental backups only capture changes since the last backup. During recovery, the full backup is restored first, and then the incremental backups are applied in sequence, bringing the database up to date efficiently.

Question 4

What does Oracle Flashback technology allow you to do?

Accepted Answer

Recover database to a specific point in time

Answer

Oracle Flashback technology allows users to view or revert database objects or the entire database to a previous point in time without needing to restore from a traditional backup. It provides various features like Flashback Query, Flashback Table, and Flashback Database, enabling quick recovery from logical errors or user mistakes by leveraging undo data.

Question 5

What is the Oracle Data Guard feature used for?

Accepted Answer

Data protection and disaster recovery

Answer

Oracle Data Guard is a comprehensive solution for creating, maintaining, managing, and monitoring one or more standby databases to protect Oracle data from failures, disasters, and human errors. It ensures high availability, data protection, and disaster recovery capabilities by maintaining synchronized copies of the production database, allowing for rapid failover.
