Oracle Database 19c: Clusterware Administration Workshop — Lesson 2: Cluster Resources, Databases, Services, Policies, and Placement

Learning Objectives

• Explain the architecture, workflow, or business purpose behind resource profiles, attributes, dependencies, and cardinality.
• Apply database and instance resources under Clusterware control and services, preferred and available instances, and failover behavior in a controlled scenario.
• Validate outcomes and troubleshoot risks involving server pools, policy management, relocation, and planned maintenance.

Detailed Topics

• resource profiles, attributes, dependencies, and cardinality
• database and instance resources under Clusterware control
• services, preferred and available instances, and failover behavior
• server pools, policy management, relocation, and planned maintenance

Instructor Demonstration

Demonstrate resource profiles, attributes, dependencies, and cardinality within a two-node clustered database platform operated through node, network, service, OCR, voting-disk, and patching incidents, then capture the exact configuration, command, transaction, report, model, query, code, or process evidence that proves the result for lesson 2.

Hands-On Exercise

Implement a controlled exercise covering database and instance resources under Clusterware control and services, preferred and available instances, and failover behavior, then introduce and resolve an exception involving server pools, policy management, relocation, and planned maintenance 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 resource profiles, attributes, dependencies, and cardinality, database and instance resources under Clusterware control, services, preferred and available instances, and failover behavior, server pools, policy management, relocation, and planned maintenance 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 Cluster Resources, Databases, Services, Policies, and Placement in a realistic Oracle Database 19c: Clusterware Administration Workshop scenario and validate the result with documented evidence.
