Oracle AI Database: High Availability New Features Live Class — Lesson 3: RAC availability, services, application continuity, transaction guard, connection management, planned maintenance

Learning Objectives

• Trace rAC availability, services, application continuity, transaction guard, connection management, planned maintenance from source condition through Oracle or application processing to the final result.
• Execute a repeatable rAC availability, services, application continuity, transaction guard, connection management, planned maintenance activity without bypassing approvals or data-quality controls.
• Diagnose failure behavior and distinguish configuration, data, access, integration, and capacity causes.

Detailed Topics

• RAC availability
• services
• application continuity
• transaction guard
• connection management
• planned maintenance
• Ownership, prerequisites, data, and acceptance criteria for rAC availability, services, application continuity, transaction guard, connection management, planned maintenance
• Security, control, integration, performance, recovery, compliance, and support implications

Instructor Demonstration

Demonstrate rAC availability, services, application continuity, transaction guard, connection management, planned maintenance within a highly available Oracle AI Database service assessed and modernized using current resilience, failover, and application-continuity capabilities. Use representative data and capture switchover or failover test log so another practitioner can reproduce and verify the result.

Hands-On Exercise

Complete a controlled activity focused on rAC availability, services, application continuity, transaction guard, connection management, planned maintenance. Introduce a realistic case of service relocation failure, isolate the cause, apply a reversible correction, and rerun the acceptance checks.

1. Record the requirement, environment, identities, dependencies, data, controls, and expected result.
2. Perform the workflow and capture course-specific evidence before and after each material change.
3. Test normal, boundary, failure, security, reconciliation, recovery, and operational conditions.
4. Document the root cause, correction, rollback, owner, support action, and next improvement priority.

Scenario Analysis

• Separate business, data, configuration, access, integration, and performance hypotheses.
• Test the hypothesis for service relocation failure with the smallest reversible change.
• Reconcile expected and actual results before approving the solution.

Troubleshooting Guidance

When rAC availability, services, application continuity, transaction guard, connection management, planned maintenance does not produce the expected result, confirm scope, effective dates, identities, data context, dependencies, and recent changes. Review switchover or failover test log before modifying configuration or data. Test one reversible hypothesis at a time, verify recovery, and confirm that the fix does not create a new control, security, performance, compliance, or integration defect.

Validation Checklist

• Prerequisites, ownership, data context, settings, and expected outcomes are documented.
• The result is reproducible and supported by switchover or failover test log.
• Security, controls, data quality, integration, performance, recovery, compliance, and support conditions are reviewed.
• Exceptions, corrective action, rollback, approvals, monitoring, and handover are recorded.

Lesson Outcome

Learners can apply RAC availability, services, application continuity, transaction guard, connection management, planned maintenance in a realistic Oracle AI Database: High Availability New Features Live Class situation and defend the result with course-specific evidence.
