Oracle GoldenGate 12c: Advanced Configuration for Oracle Ed 1 — Lesson 2: Filtering, Mapping, Transformation, and Conflict Controls

Technical Scope

• TABLE and MAP wildcards, filters, SQLEXEC, tokens, and column conversion
• DDL replication scope, object mapping, sequence handling, and metadata differences
• bidirectional conflict sources, loop detection, exceptions, and resolution strategy
• test matrices, deterministic transformations, discard analysis, and reconciliation

Instructor Demonstration

The instructor will configure and verify TABLE and MAP wildcards, filters, SQLEXEC, tokens, and column conversion in the context of a multi-database replication estate requiring scalable apply, selective routing, planned failover, and zero-guesswork recovery. The demonstration captures commands, configuration, transactions, output, logs, plans, or screenshots that prove both the intended behavior and the control boundary.

Applied Workshop

Learners complete a controlled exercise covering DDL replication scope, object mapping, sequence handling, and metadata differences and bidirectional conflict sources, loop detection, exceptions, and resolution strategy, then introduce a realistic exception involving test matrices, deterministic transformations, discard analysis, and reconciliation. They record assumptions, exact steps, expected and observed results, a reversible correction, and the evidence required for operational acceptance.

1. Confirm scope, identities, data, dependencies, controls, and expected result.
2. Perform the product-specific configuration, development, analysis, or business-process task.
3. Capture reproducible technical or transaction evidence and compare it with the expected value.
4. Explain the operational, security, performance, data-quality, or business trade-off.

Validation Standard

Acceptance for Filtering, Mapping, Transformation, and Conflict Controls requires the result to be reproducible, traceable to approved inputs, consistent with the relevant Oracle or platform behavior, and supported by checks for security, data integrity, reliability, performance, and recoverability.

• The intended target, scope, and ownership are verified.
• Expected-value and negative-path checks pass.
• Security, reliability, performance, data quality, and support impacts are reviewed.
• Unexpected behavior is resolved before acceptance.

Failure Analysis

When the result differs from expectation, learners isolate the smallest proven cause across TABLE and MAP wildcards, filters, SQLEXEC, tokens, and column conversion, DDL replication scope, object mapping, sequence handling, and metadata differences, bidirectional conflict sources, loop detection, exceptions, and resolution strategy; they avoid speculative production changes, preserve evidence, apply the lowest-risk correction, rerun the test, and document prevention.

Practical Outcome

Complete and defend a validated result for Filtering, Mapping, Transformation, and Conflict Controls with a reusable implementation record or runbook.
