Oracle WebLogic Server 14c: Administration II — Lesson 3: JDBC, JMS, Transactions, Work Managers, and Resource Reliability

Learning Objectives

• Explain the purpose and operating context of multi data sources, Active GridLink awareness, FAN, testing, and failover.
• Apply JMS servers, stores, distributed destinations, SAF, and migration and JTA coordinators, recovery services, timeouts, and transaction troubleshooting in a controlled environment.
• Validate outcomes and troubleshoot risks involving work managers, constraints, overload protection, and application isolation.

Detailed Topics

• multi data sources, Active GridLink awareness, FAN, testing, and failover
• JMS servers, stores, distributed destinations, SAF, and migration
• JTA coordinators, recovery services, timeouts, and transaction troubleshooting
• work managers, constraints, overload protection, and application isolation

Instructor Demonstration

Demonstrate multi data sources, Active GridLink awareness, FAN, testing, 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 JMS servers, stores, distributed destinations, SAF, and migration and JTA coordinators, recovery services, timeouts, and transaction troubleshooting; introduce an exception involving work managers, constraints, overload protection, and application isolation, 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 multi data sources, Active GridLink awareness, FAN, testing, and failover, JMS servers, stores, distributed destinations, SAF, and migration, JTA coordinators, recovery services, timeouts, and transaction troubleshooting, work managers, constraints, overload protection, and application isolation 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 JDBC, JMS, Transactions, Work Managers, and Resource Reliability in a realistic Oracle WebLogic Server 14c: Administration II scenario and defend the result with documented evidence.
