Oracle WebLogic Server 14c: Performance Tuning Workshop — Lesson 4: Load Testing, Profiling, Monitoring, Capacity, Change Control, and Handoff

Learning Objectives

• Explain the purpose and operating context of load-test design, ramp-up, steady state, saturation, soak, and failure tests.
• Apply JFR and profiling awareness, thread and heap analysis, and code hotspots and WLDF, dashboards, alerts, thresholds, and regression detection in a controlled environment.
• Validate outcomes and troubleshoot risks involving capacity model, tuning record, deployment validation, and performance runbook.

Detailed Topics

• load-test design, ramp-up, steady state, saturation, soak, and failure tests
• JFR and profiling awareness, thread and heap analysis, and code hotspots
• WLDF, dashboards, alerts, thresholds, and regression detection
• capacity model, tuning record, deployment validation, and performance runbook

Instructor Demonstration

Demonstrate load-test design, ramp-up, steady state, saturation, soak, and failure tests for a WebLogic application benchmarked and tuned against response-time and throughput objectives; capture the exact configuration, code, command, transaction, query, dashboard, model, schedule, or report evidence that proves the expected result.

Hands-On Exercise

Complete a controlled Oracle WebLogic Server 14c: Performance Tuning Workshop exercise covering JFR and profiling awareness, thread and heap analysis, and code hotspots and WLDF, dashboards, alerts, thresholds, and regression detection; introduce an exception involving capacity model, tuning record, deployment validation, and performance runbook, diagnose it from evidence, apply the smallest reversible correction, and rerun acceptance checks.

1. Confirm scope, prerequisites, identities, dependencies, data, risks, and expected outcome.
2. Perform the course-specific configuration, development, administration, analysis, or business-process workflow.
3. Capture commands, settings, records, logs, screenshots, reports, metrics, or test results.
4. Compare the observed result with acceptance criteria and document corrective or preventive action.

Scenario Analysis

• Identify the technical or business decision and the stakeholders affected by it.
• Compare security, performance, reliability, compliance, cost, usability, and support trade-offs.
• Define rollback, recovery, communication, evidence, ownership, and escalation requirements.

Troubleshooting Guidance

Diagnose issues involving load-test design, ramp-up, steady state, saturation, soak, and failure tests, JFR and profiling awareness, thread and heap analysis, and code hotspots, WLDF, dashboards, alerts, thresholds, and regression detection, capacity model, tuning record, deployment validation, and performance runbook without making an unverified production change. Separate symptoms from causes, gather time-correlated evidence, test a reversible hypothesis, validate the correction, and record recurrence controls.

Validation Checklist

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

Lesson Outcome

Learners can apply Load Testing, Profiling, Monitoring, Capacity, Change Control, and Handoff in a realistic Oracle WebLogic Server 14c: Performance Tuning Workshop scenario and defend the result with documented evidence.
