Oracle GoldenGate 19c: Troubleshooting and Tuning — Lesson 3: Apply, Mapping, Conflict, and Data Consistency Problems

Technical Scope

• Replicat reports, SQL errors, and transactions
• mapping, keys, logging, and metadata
• Integrated or Parallel Replicat dependencies
• compare, discard, exception, conflict, and repair

Instructor Demonstration

Demonstrate Replicat reports, SQL errors, and transactions inside four incidents with overlapping symptoms that require stage-by-stage evidence, then capture the exact configuration, command, transaction, report, or code evidence that proves the result.

Applied Workshop

Implement a controlled workshop covering mapping, keys, logging, and metadata and Integrated or Parallel Replicat dependencies, then test a failure or exception involving compare, discard, exception, conflict, and repair.

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 Apply, Mapping, Conflict, and Data Consistency Problems 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, SQL errors, and transactions, mapping, keys, logging, and metadata, Integrated or Parallel Replicat dependencies, or compare, discard, exception, conflict, and repair without making an unverified production change.

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