Oracle GoldenGate 19c: Troubleshooting and Tuning — Lesson 4: Lag, Throughput, Database Performance, and Tuning

Technical Scope

• end-to-end and per-stage lag
• Extract and Replicat parameters
• database waits, SQL, commits, I/O, and resources
• load tests, rollback, alerts, and capacity

Instructor Demonstration

Demonstrate end-to-end and per-stage lag 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 Extract and Replicat parameters and database waits, SQL, commits, I/O, and resources, then test a failure or exception involving load tests, rollback, alerts, and capacity.

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 Lag, Throughput, Database Performance, and Tuning 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 end-to-end and per-stage lag, Extract and Replicat parameters, database waits, SQL, commits, I/O, and resources, or load tests, rollback, alerts, and capacity without making an unverified production change.

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