Description
Oracle Flashback Technology provides powerful and efficient ways to recover from human errors, logical data corruptions, and unwanted changes to your database. This course, Oracle Flashback Technology: Mastering Data Recovery and Archiving, is designed to guide you through the extensive capabilities of Flashback features. You'll learn how to recover deleted data, restore tables, roll back transactions, and manage historical archives. Whether you are a Database Administrator (DBA) or a developer, this course will enhance your data recovery skills and deepen your understanding of Oracle's data protection mechanisms.Section 1: Introduction to Flashback TechnologyThis section introduces the core concepts of Oracle Flashback Technology, focusing on undo management and recovering from accidental deletions. You will learn how to use Flashback features to reverse data changes and manage undo tablespace effectively.Lecture 1: Overview and Undo Management (Preview enabled)Lecture 2: Handling Accidental Delete ScenariosLecture 3: Utilizing Flashback for Deletes and UpdatesSection 2: Requirements for Flashback OperationsTo effectively use Flashback capabilities, certain database configurations must be in place. This section covers the prerequisites, such as enabling Archive Log Mode and using version and transaction queries to track changes.Lecture 4: Enabling Archive Log Mode (Preview enabled)Lecture 5: Version Query for Delete and Commit OperationsLecture 6: Understanding Transaction QueriesLecture 7: Advanced Transaction Query TechniquesSection 3: Flashback Table OperationsIn this section, you'll explore how to use Flashback Table to recover tables to a previous state using timestamps or restore points. You'll also learn about the behavior of indexes during these operations.Lecture 8: Theoretical Concepts of Flashback TableLecture 9: Flashback Table to Timestamp - Lab ExampleLecture 10: Flashback Table to Restore Point - Lab ExampleLecture 11: Managing Index Behavior during Flashback Table OperationsSection 4: Flashback Table to Before DropOracle Flashback provides the capability to restore dropped tables. This section covers the theory and practical applications of Flashback Table to Before Drop, including handling cases where tables are dropped multiple times.Lecture 12: Flashback Table to Before Drop - Theoretical OverviewLecture 13: In-depth Analysis of Flashback Table to Before DropLecture 14: Simple Example of Restoring a Dropped TableLecture 15: Using Flashback Table for Truncated TablesLecture 16: Restoring Tables Dropped Multiple TimesSection 5: Flashback DatabaseFlashback Database allows you to rewind your entire database to a previous point in time. This section covers the concepts, restrictions, and effects on data files, along with examples using System Change Numbers (SCNs) and restore points.Lecture 17: Concepts and Restrictions of Flashback DatabaseLecture 18: Impact on Data Files and Continuous Log ModeLecture 19: Flashback Database and Enabling Flashback Log ModeLecture 20: Rewinding Database using SCN - Practical ExampleLecture 21: Differences between Normal and Guaranteed Restore PointsSection 6: Flashback Data ArchiveFlashback Data Archive (FDA) provides a robust solution for long-term data retention and auditing. This section dives into creating, managing, and utilizing Flashback Data Archives to preserve historical data.Lecture 22: Overview of Flashback Data Archives - Concepts, Creation, and ManagementLecture 23: Advanced Management of Flashback Data ArchivesLecture 24: Assigning Tables to Various Flashback Data Archive ObjectsLecture 25: Managing Flashback TransactionsConclusion:By the end of this course, you will be proficient in using Oracle Flashback Technology to recover from data loss, manage historical archives, and ensure data integrity. You'll be equipped with practical skills to handle data recovery scenarios, optimize undo tablespace, and leverage Oracle's Flashback features to safeguard your database.
