Oracle GoldenGate 19c: Fundamentals for Oracle — Lesson 3: Replicat, Mapping, Filtering, Transformations, Errors, and Consistency

Learning Objectives

• Explain the architecture, workflow, or business purpose behind Replicat groups, target setup, MAP and TABLE parameters.
• Apply key selection, COLMAP, filters, conversions, and sequence handling and constraints, triggers, transactions, commit behavior, and collision awareness in a controlled scenario.
• Validate outcomes and troubleshoot risks involving errors, discard files, exception handling, compare, and reconciliation.

Detailed Topics

• Replicat groups, target setup, MAP and TABLE parameters
• key selection, COLMAP, filters, conversions, and sequence handling
• constraints, triggers, transactions, commit behavior, and collision awareness
• errors, discard files, exception handling, compare, and reconciliation

Instructor Demonstration

Demonstrate Replicat groups, target setup, MAP and TABLE parameters within a transactional Oracle schema replicated to a reporting target with controlled initial load and recoverable operations, then capture the exact configuration, command, transaction, report, model, query, code, or process evidence that proves the result for lesson 3.

Hands-On Exercise

Implement a controlled exercise covering key selection, COLMAP, filters, conversions, and sequence handling and constraints, triggers, transactions, commit behavior, and collision awareness, then introduce and resolve an exception involving errors, discard files, exception handling, compare, and reconciliation while preserving before-and-after evidence.

1. Confirm the environment, identities, inputs, dependencies, risks, and expected outcome.
2. Complete the course-specific configuration, development, analysis, or process workflow.
3. Capture settings, commands, data, outputs, logs, reports, screenshots, calculations, or test results.
4. Compare the observed result with acceptance criteria and document corrective action.

Scenario Analysis

• Identify the technical or business decision that must be made.
• Compare valid approaches and their security, performance, reliability, cost, compliance, and support trade-offs.
• Define rollback, recovery, ownership, communication, and evidence requirements.

Troubleshooting Guidance

Diagnose issues across Replicat groups, target setup, MAP and TABLE parameters, key selection, COLMAP, filters, conversions, and sequence handling, constraints, triggers, transactions, commit behavior, and collision awareness, errors, discard files, exception handling, compare, and reconciliation without making an unverified production change. Separate symptoms from causes, gather evidence, test the smallest reversible correction, rerun validation, and record preventive action.

Validation Checklist

• The requirement, scope, inputs, dependencies, and expected result are documented.
• The result is reproducible and supported by course-specific evidence.
• Normal, boundary, failure, security, performance, and operational conditions are reviewed.
• Exceptions, rollback, ownership, and the next improvement priority are recorded.

Lesson Outcome

Learners can apply Replicat, Mapping, Filtering, Transformations, Errors, and Consistency in a realistic Oracle GoldenGate 19c: Fundamentals for Oracle scenario and validate the result with documented evidence.
