Oracle GoldenGate 12c: Troubleshooting and Tuning Ed 1 — Lesson 3: Replicat Errors, Mapping, Constraints, and Data Divergence

Technical Scope

• Replicat reports and SQL errors
• MAP, TABLE, keys, conversions, and filters
• constraints, triggers, logging, and target behavior
• discard, exception, compare, and repair awareness

Instructor Demonstration

Demonstrate Replicat reports and SQL errors inside a replication system deliberately degraded at different data-path stages, then capture the exact configuration, command, transaction, report, or code evidence that proves the result.

Applied Workshop

Implement a controlled workshop covering MAP, TABLE, keys, conversions, and filters and constraints, triggers, logging, and target behavior, then test a failure or exception involving discard, exception, compare, and repair awareness.

1. Confirm environment, identity, data, dependencies, and expected result.
2. Complete the product-specific implementation or analysis.
3. Capture commands, configuration, output, logs, transactions, or reports.
4. Explain the operational, security, performance, or business trade-off.

Validation Standard

The Replicat Errors, Mapping, Constraints, and Data Divergence result must be reproducible, traceable to approved inputs, and consistent with the expected Oracle product behavior.

• The intended target and ownership are verified.
• The result is supported by reproducible evidence.
• Security, performance, reliability, and support impact are reviewed.
• Unexpected behavior is investigated before acceptance.

Failure Analysis

Diagnose issues in Replicat reports and SQL errors, MAP, TABLE, keys, conversions, and filters, constraints, triggers, logging, and target behavior, or discard, exception, compare, and repair awareness without making an unverified production change.

Learners isolate the smallest proven cause, apply a reversible correction, rerun validation, and record the preventive action.
