Oracle WebLogic Server 14c: Administration II — Lesson 1: Clusters, Dynamic Servers, Session Replication, Load Balancing, and Migration

Learning Objectives

• Explain the purpose and operating context of cluster communication, membership, channels, replication, and failover.
• Apply dynamic clusters, server templates, scaling, and lifecycle and HTTP session persistence, replication groups, and failover validation in a controlled environment.
• Validate outcomes and troubleshoot risks involving whole-server and service migration, leasing, candidates, and recovery.

Detailed Topics

• cluster communication, membership, channels, replication, and failover
• dynamic clusters, server templates, scaling, and lifecycle
• HTTP session persistence, replication groups, and failover validation
• whole-server and service migration, leasing, candidates, and recovery

Instructor Demonstration

Demonstrate cluster communication, membership, channels, replication, and failover for a multi-cluster WebLogic platform strengthened for failover, secure integration, automation, and rolling maintenance; 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: Administration II exercise covering dynamic clusters, server templates, scaling, and lifecycle and HTTP session persistence, replication groups, and failover validation; introduce an exception involving whole-server and service migration, leasing, candidates, and recovery, 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 cluster communication, membership, channels, replication, and failover, dynamic clusters, server templates, scaling, and lifecycle, HTTP session persistence, replication groups, and failover validation, whole-server and service migration, leasing, candidates, and recovery 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 Clusters, Dynamic Servers, Session Replication, Load Balancing, and Migration in a realistic Oracle WebLogic Server 14c: Administration II scenario and defend the result with documented evidence.
