Oracle Database 19c: Backup and Recovery — Lesson 4: Point-in-Time Recovery, Flashback, Duplication, and Rehearsal

Technical Scope

• database and PDB PITR concepts
• table and tablespace recovery awareness
• flashback database and restore points
• duplicate database and disaster-runbook practice

Instructor Demonstration

Demonstrate database and PDB PITR concepts inside a recovery matrix driven by actual datafile, control-file, logical-error, and disaster scenarios, then capture the exact configuration, command, transaction, report, or code evidence that proves the result.

Applied Workshop

Implement a controlled workshop covering table and tablespace recovery awareness and flashback database and restore points, then test a failure or exception involving duplicate database and disaster-runbook practice.

1. Confirm environment, identity, data, dependencies, and expected result.
2. Complete the product-specific implementation or analysis.
3. Capture commands, configuration, output, logs, transactions, or reports.
4. Explain the operational, security, performance, or business trade-off.

Validation Standard

The Point-in-Time Recovery, Flashback, Duplication, and Rehearsal result must be reproducible, traceable to approved inputs, and consistent with the expected Oracle product behavior.

• The intended target and ownership are verified.
• The result is supported by reproducible evidence.
• Security, performance, reliability, and support impact are reviewed.
• Unexpected behavior is investigated before acceptance.

Failure Analysis

Diagnose issues in database and PDB PITR concepts, table and tablespace recovery awareness, flashback database and restore points, or duplicate database and disaster-runbook practice without making an unverified production change.

Learners isolate the smallest proven cause, apply a reversible correction, rerun validation, and record the preventive action.
