Oracle Database 19c: Data Guard Administration Workshop — Lesson 2: Redo Apply, Broker Configuration, Monitoring, and Routine Administration

Technical Scope

• managed recovery, real-time apply, archive apply, delay, and apply services
• Data Guard Broker configuration, properties, validation, and command-line workflow
• transport lag, apply lag, process views, alert logs, and threshold monitoring
• maintenance, parameter changes, patch coordination, and role-aware procedures

Instructor Demonstration

Demonstrate managed recovery, real-time apply, archive apply, delay, and apply services within a mission-critical Oracle Database protected by a physical standby across sites, validated for planned switchover, unplanned failover, data protection, and operational recovery, then capture the exact configuration, command, transaction, report, trace, or code evidence that proves the expected result.

Applied Workshop

Implement a controlled workshop covering Data Guard Broker configuration, properties, validation, and command-line workflow and transport lag, apply lag, process views, alert logs, and threshold monitoring, then test a failure, exception, or business-control scenario involving maintenance, parameter changes, patch coordination, and role-aware procedures.

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 Redo Apply, Broker Configuration, Monitoring, and Routine Administration 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 managed recovery, real-time apply, archive apply, delay, and apply services, Data Guard Broker configuration, properties, validation, and command-line workflow, transport lag, apply lag, process views, alert logs, and threshold monitoring, or maintenance, parameter changes, patch coordination, and role-aware procedures 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 Redo Apply, Broker Configuration, Monitoring, and Routine Administration and defend the result with documented evidence.
