Oracle GoldenGate 23ai: Fundamentals (ELS) — Lesson 4: Monitoring, Lag Analysis, Error Recovery, Security, Performance, and Maintenance

Learning Objectives

• Describe how monitoring, lag analysis, error recovery, security, performance, and maintenance changes application behaviour, data, accounting, or service delivery.
• Construct a repeatable sequence with known inputs, controls, outputs, and rollback points.
• Evaluate security, correctness, performance, recoverability, and support readiness.

Detailed Topics

• Monitoring
• Lag Analysis
• Error Recovery
• Security
• Performance
• Maintenance
• ownership, prerequisites, data, and acceptance criteria for monitoring, lag analysis, error recovery, security, performance, and maintenance
• security, control, integration, performance, recovery, and support implications

Instructor Demonstration

Demonstrate monitoring, lag analysis, error recovery, security, performance, and maintenance within a database replication flow configured for continuous change delivery with recoverable checkpoints and measurable lag. Use representative data and capture lag metrics, discard and error logs so another practitioner can verify the result.

Hands-On Exercise

Complete a controlled Oracle GoldenGate 23ai: Fundamentals (ELS) activity focused on monitoring, lag analysis, error recovery, security, performance, and maintenance. Introduce a realistic case of duplicate delivery, isolate its cause, apply a reversible correction, and rerun the acceptance checks.

1. Record the requirement, environment, identities, dependencies, data, controls, and expected result.
2. Perform the workflow and capture course-specific evidence before and after each material change.
3. Test normal, boundary, failure, security, reconciliation, recovery, and operational conditions.
4. Document the root cause, correction, rollback, owner, support action, and next improvement priority.

Scenario Analysis

• Separate mandatory requirements from optional convenience and local workaround requests.
• Compare the proposed approach against security, reliability, usability, cost, and audit expectations.
• Select the smallest supportable change and assign follow-up ownership.

Troubleshooting Guidance

When monitoring, lag analysis, error recovery, security, performance, and maintenance does not produce the expected result, confirm scope, effective dates, identities, data context, dependencies, and recent changes. Review the most relevant lag metrics, discard and error logs before editing configuration. Test one reversible hypothesis at a time, verify recovery, and confirm that the fix does not create duplicate delivery elsewhere.

Validation Checklist

• Prerequisites, ownership, data context, settings, and expected outcomes are documented.
• The result is reproducible and supported by lag metrics, discard and error logs.
• Security, controls, data quality, integration, performance, recovery, and support conditions are reviewed.
• Exceptions, corrective action, rollback, approvals, monitoring, and handover are recorded.

Lesson Outcome

Learners can apply Monitoring, Lag Analysis, Error Recovery, Security, Performance, and Maintenance in a realistic Oracle GoldenGate 23ai: Fundamentals (ELS) situation and defend the result with course-specific evidence.
