Oracle Database 19c: Data Guard Administration Workshop — Lesson 1: Data Guard Architecture, Prerequisites, Redo Transport, and Standby Creation

Technical Scope

• Data Guard roles, protection modes, redo flow, standby redo logs, and services
• primary prerequisites, FORCE LOGGING, parameters, listener, and connectivity
• RMAN duplicate or backup-based physical standby creation and validation
• redo transport destinations, synchronous and asynchronous modes, gaps, and checks

Instructor Demonstration

Demonstrate Data Guard roles, protection modes, redo flow, standby redo logs, and 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 primary prerequisites, FORCE LOGGING, parameters, listener, and connectivity and RMAN duplicate or backup-based physical standby creation and validation, then test a failure, exception, or business-control scenario involving redo transport destinations, synchronous and asynchronous modes, gaps, and checks.

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 Data Guard Architecture, Prerequisites, Redo Transport, and Standby Creation 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 roles, protection modes, redo flow, standby redo logs, and services, primary prerequisites, FORCE LOGGING, parameters, listener, and connectivity, RMAN duplicate or backup-based physical standby creation and validation, or redo transport destinations, synchronous and asynchronous modes, gaps, and checks 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 Data Guard Architecture, Prerequisites, Redo Transport, and Standby Creation and defend the result with documented evidence.
