Oracle GoldenGate 12c: Troubleshooting and Tuning Ed 1 — Lesson 4: Lag Analysis, Throughput Tuning, Resources, and Validation

Technical Scope

• process and checkpoint lag
• batching, groups, transactions, and caches
• database waits, SQL, I/O, CPU, and network
• controlled tuning, load tests, capacity, and documentation

Instructor Demonstration

Demonstrate process and checkpoint lag 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 batching, groups, transactions, and caches and database waits, SQL, I/O, CPU, and network, then test a failure or exception involving controlled tuning, load tests, capacity, and documentation.

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 Analysis, Throughput Tuning, Resources, and Validation 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 process and checkpoint lag, batching, groups, transactions, and caches, database waits, SQL, I/O, CPU, and network, or controlled tuning, load tests, capacity, and documentation without making an unverified production change.

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