Oracle Database 19c: SQL Tuning Workshop — Lesson 4: SQL Tuning Advisor, Profiles, Baselines, Regression Control, and Handoff

Learning Objectives

• Explain the architecture, workflow, or business purpose behind SQL Tuning Advisor tasks, findings, rationale, and acceptance.
• Apply SQL profiles and SQL plan management concepts and plan baselines, evolution, capture, regression detection, and rollback in a controlled scenario.
• Validate outcomes and troubleshoot risks involving load testing, change records, monitoring thresholds, and tuning runbook.

Detailed Topics

• SQL Tuning Advisor tasks, findings, rationale, and acceptance
• SQL profiles and SQL plan management concepts
• plan baselines, evolution, capture, regression detection, and rollback
• load testing, change records, monitoring thresholds, and tuning runbook

Instructor Demonstration

Demonstrate SQL Tuning Advisor tasks, findings, rationale, and acceptance within a reporting query and transaction query tuned without sacrificing correctness, concurrency, or plan stability, then capture the exact configuration, command, transaction, report, model, query, code, or process evidence that proves the result for lesson 4.

Hands-On Exercise

Implement a controlled exercise covering SQL profiles and SQL plan management concepts and plan baselines, evolution, capture, regression detection, and rollback, then introduce and resolve an exception involving load testing, change records, monitoring thresholds, and tuning runbook while preserving before-and-after evidence.

1. Confirm the environment, identities, inputs, dependencies, risks, and expected outcome.
2. Complete the course-specific configuration, development, analysis, or process workflow.
3. Capture settings, commands, data, outputs, logs, reports, screenshots, calculations, or test results.
4. Compare the observed result with acceptance criteria and document corrective action.

Scenario Analysis

• Identify the technical or business decision that must be made.
• Compare valid approaches and their security, performance, reliability, cost, compliance, and support trade-offs.
• Define rollback, recovery, ownership, communication, and evidence requirements.

Troubleshooting Guidance

Diagnose issues across SQL Tuning Advisor tasks, findings, rationale, and acceptance, SQL profiles and SQL plan management concepts, plan baselines, evolution, capture, regression detection, and rollback, load testing, change records, monitoring thresholds, and tuning runbook without making an unverified production change. Separate symptoms from causes, gather evidence, test the smallest reversible correction, rerun validation, and record preventive action.

Validation Checklist

• The requirement, scope, inputs, dependencies, and expected result are documented.
• The result is reproducible and supported by course-specific evidence.
• Normal, boundary, failure, security, performance, and operational conditions are reviewed.
• Exceptions, rollback, ownership, and the next improvement priority are recorded.

Lesson Outcome

Learners can apply SQL Tuning Advisor, Profiles, Baselines, Regression Control, and Handoff in a realistic Oracle Database 19c: SQL Tuning Workshop scenario and validate the result with documented evidence.
