S Oracle Solaris 11 Advanced System Administration (D72967GC60) — Lesson 4: Performance, DTrace, Resource Management, Fault Diagnosis, and System Recovery

Learning Objectives

• Assess the Oracle objects, services, rules, reports, interfaces, or code used in performance, dtrace, resource management, fault diagnosis, and system recovery.
• Operate a hands-on implementation or diagnostic sequence without bypassing approvals.
• Resolve reproducibility by comparing expected and actual evidence.

Detailed Topics

• Performance
• DTrace
• Resource Management
• Fault Diagnosis
• System Recovery
• ownership, prerequisites, data, and acceptance criteria for performance, dtrace, resource management, fault diagnosis, and system recovery
• security, control, integration, performance, recovery, and support implications

Instructor Demonstration

Demonstrate performance, dtrace, resource management, fault diagnosis, and system recovery within a Solaris 11 environment administered for resilient storage, isolated workloads, reliable networking, controlled updates, and deep diagnostics. Use representative data and capture DTrace output, fault-management logs so another practitioner can verify the result.

Hands-On Exercise

Complete a controlled S Oracle Solaris 11 Advanced System Administration (D72967GC60) activity focused on performance, dtrace, resource management, fault diagnosis, and system recovery. Introduce a realistic case of pool 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

• Map the end-to-end flow from source input through Oracle processing to the final output.
• Locate the control point most likely to prevent or expose pool failure.
• Recommend monitoring, escalation, and handover requirements for production support.

Troubleshooting Guidance

When performance, dtrace, resource management, fault diagnosis, and system recovery does not produce the expected result, confirm scope, effective dates, identities, data context, dependencies, and recent changes. Review the most relevant DTrace output, fault-management logs before editing configuration. Test one reversible hypothesis at a time, verify recovery, and confirm that the fix does not create pool failure elsewhere.

Validation Checklist

• Prerequisites, ownership, data context, settings, and expected outcomes are documented.
• The result is reproducible and supported by DTrace output, fault-management logs.
• Security, controls, data quality, integration, performance, recovery, and support conditions are reviewed.
• Exceptions, corrective action, rollback, approvals, monitoring, and handover are recorded.

Lesson Outcome

Learners can apply Performance, DTrace, Resource Management, Fault Diagnosis, and System Recovery in a realistic S Oracle Solaris 11 Advanced System Administration (D72967GC60) situation and defend the result with course-specific evidence.
