Oracle Database 19c: New Features for Administrators Ed 1 — Lesson 2: Availability, Data Guard, Recovery, RMAN, and Lifecycle Enhancements

Technical Scope

• Data Guard broker, Active Data Guard, observer, and failover enhancements
• RMAN duplication, recovery catalog, validation, and restore improvements
• online maintenance, rolling operations, service continuity, and patching context
• failure simulations, recovery objectives, evidence, and rollback criteria

Instructor Demonstration

Demonstrate Data Guard broker, Active Data Guard, observer, and failover enhancements within a database operations team assessing Oracle Database 19c features for a controlled upgrade from an earlier release while preserving security, performance, and recoverability, then capture the exact configuration, command, transaction, report, trace, or code evidence that proves the expected result.

Applied Workshop

Implement a controlled workshop covering RMAN duplication, recovery catalog, validation, and restore improvements and online maintenance, rolling operations, service continuity, and patching context, then test a failure, exception, or business-control scenario involving failure simulations, recovery objectives, evidence, and rollback criteria.

1. Confirm the environment, identities, data, dependencies, controls, and expected result.
2. Complete the product-specific configuration, development, analysis, or business-process task.
3. Capture commands, configuration, output, logs, transactions, reports, or test evidence.
4. Explain the operational, security, performance, data-quality, or business trade-off.

Validation Standard

The Availability, Data Guard, Recovery, RMAN, and Lifecycle Enhancements result must be reproducible, traceable to approved inputs, and consistent with expected Oracle product or business-process behavior.

• The intended target, scope, and ownership are verified.
• The result is supported by reproducible evidence and expected-value checks.
• Security, performance, reliability, data quality, and support impact are reviewed.
• Unexpected behavior is investigated before acceptance or release.

Failure Analysis

Diagnose issues in Data Guard broker, Active Data Guard, observer, and failover enhancements, RMAN duplication, recovery catalog, validation, and restore improvements, online maintenance, rolling operations, service continuity, and patching context, or failure simulations, recovery objectives, evidence, and rollback criteria without making an unverified production change.

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

Practical Outcome

Complete a validated implementation or analysis for Availability, Data Guard, Recovery, RMAN, and Lifecycle Enhancements and defend the result with documented evidence.
