Oracle Database 19c: Backup and Recovery — Lesson 1: Recovery Architecture, Failure Analysis, and RMAN Configuration

Technical Scope

• failure categories and recovery objectives
• ARCHIVELOG mode and redo requirements
• RMAN repositories, channels, and devices
• retention, autobackup, and recovery-window design

Instructor Demonstration

Demonstrate failure categories and recovery objectives 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 ARCHIVELOG mode and redo requirements and RMAN repositories, channels, and devices, then test a failure or exception involving retention, autobackup, and recovery-window design.

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 Recovery Architecture, Failure Analysis, and RMAN Configuration 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 failure categories and recovery objectives, ARCHIVELOG mode and redo requirements, RMAN repositories, channels, and devices, or retention, autobackup, and recovery-window design without making an unverified production change.

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