Getting Started with MySQL Database Service — Lesson 1: OCI Foundations, VCN Prerequisites, MySQL DB System Creation, and Access

Learning Objectives

• Explain the architecture, workflow, or business purpose behind tenancy, compartments, policies, regions, and service limits.
• Apply VCNs, subnets, security rules, endpoints, and private connectivity and MySQL DB system shapes, storage, versions, maintenance, and creation in a controlled scenario.
• Validate outcomes and troubleshoot risks involving bastion or application access, clients, DNS, and connection validation.

Detailed Topics

• tenancy, compartments, policies, regions, and service limits
• VCNs, subnets, security rules, endpoints, and private connectivity
• MySQL DB system shapes, storage, versions, maintenance, and creation
• bastion or application access, clients, DNS, and connection validation

Instructor Demonstration

Demonstrate tenancy, compartments, policies, regions, and service limits within a small application database migrated to OCI MySQL Database Service and prepared for reliable production use, then capture the exact configuration, command, transaction, report, model, query, code, or process evidence that proves the result for lesson 1.

Hands-On Exercise

Implement a controlled exercise covering VCNs, subnets, security rules, endpoints, and private connectivity and MySQL DB system shapes, storage, versions, maintenance, and creation, then introduce and resolve an exception involving bastion or application access, clients, DNS, and connection validation 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 tenancy, compartments, policies, regions, and service limits, VCNs, subnets, security rules, endpoints, and private connectivity, MySQL DB system shapes, storage, versions, maintenance, and creation, bastion or application access, clients, DNS, and connection validation 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 OCI Foundations, VCN Prerequisites, MySQL DB System Creation, and Access in a realistic Getting Started with MySQL Database Service scenario and validate the result with documented evidence.
