Oracle GoldenGate 23ai: Fundamentals (ELS) — Lesson 3: Initial Load, Filtering, Mapping, Transformation, DDL, and Conflict Awareness

Learning Objectives

• Interpret prerequisites, ownership, dependencies, and failure conditions for initial load, filtering, mapping, transformation, ddl, and conflict awareness.
• Perform the course-specific workflow while recording evidence at each material checkpoint.
• Prove the solution against security, control, reliability, performance, and support criteria.

Detailed Topics

• Initial Load
• Filtering
• Mapping
• Transformation
• DDL
• Conflict Awareness
• ownership, prerequisites, data, and acceptance criteria for initial load, filtering, mapping, transformation, ddl, and conflict awareness
• security, control, integration, performance, recovery, and support implications

Instructor Demonstration

Demonstrate initial load, filtering, mapping, transformation, ddl, and conflict awareness within a database replication flow configured for continuous change delivery with recoverable checkpoints and measurable lag. Use representative data and capture replicated rows, mapping results so another practitioner can verify the result.

Hands-On Exercise

Complete a controlled Oracle GoldenGate 23ai: Fundamentals (ELS) activity focused on initial load, filtering, mapping, transformation, ddl, and conflict awareness. Introduce a realistic case of mapping mistakes, 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

• Establish current state, desired state, constraints, and acceptable service impact.
• Compare alternative implementation or diagnostic approaches and their rollback consequences.
• Document the decision, evidence, exception, corrective action, and measurable improvement target.

Troubleshooting Guidance

When initial load, filtering, mapping, transformation, ddl, and conflict awareness does not produce the expected result, confirm scope, effective dates, identities, data context, dependencies, and recent changes. Review the most relevant replicated rows, mapping results before editing configuration. Test one reversible hypothesis at a time, verify recovery, and confirm that the fix does not create mapping mistakes elsewhere.

Validation Checklist

• Prerequisites, ownership, data context, settings, and expected outcomes are documented.
• The result is reproducible and supported by replicated rows, mapping results.
• 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 Initial Load, Filtering, Mapping, Transformation, DDL, and Conflict Awareness in a realistic Oracle GoldenGate 23ai: Fundamentals (ELS) situation and defend the result with course-specific evidence.
