Oracle GoldenGate 12c: Troubleshooting and Tuning Ed 1 — Lesson 2: Extract, Data Pump, Source Logs, and Trail Problems

Technical Scope

• Extract registration and source-log access
• archive-log availability and retention
• local and remote trails
• Data Pump networking, Collector, compression, and encryption

Instructor Demonstration

Demonstrate Extract registration and source-log access 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 archive-log availability and retention and local and remote trails, then test a failure or exception involving Data Pump networking, Collector, compression, and encryption.

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 Extract, Data Pump, Source Logs, and Trail 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 Extract registration and source-log access, archive-log availability and retention, local and remote trails, or Data Pump networking, Collector, compression, and encryption without making an unverified production change.

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