Red Hat JBoss Application Administration I (AD248) — Lesson 2: Deployments, Configuration Profiles, Datasources, Messaging, and Transactions

Learning Objectives

• Explain the structures, services, data, settings, roles, and dependencies governing deployment management and profiles and groups.
• Implement and validate datasources, messaging, and transactions using reviewable evidence.
• Evaluate the condition where a change succeeds in one environment but fails elsewhere because inventory, policy, version, or runtime assumptions differ and select a proportionate corrective response.

Detailed Topics

• deployment management applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• profiles and groups applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• datasources applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• messaging applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• transactions applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.

Instructor Demonstration

The instructor traces a middleware administration team preparing JBoss EAP services for secure, repeatable enterprise application delivery. The walkthrough connects navigation, commands, configuration logic, system messages, and evidence captured in the JBoss EAP administration baseline, deployment and resource records, monitoring checklist, and recovery runbook. It also tests the exception where a change succeeds in one environment but fails elsewhere because inventory, policy, version, or runtime assumptions differ.

Hands-On Exercise

Complete a controlled Red Hat exercise covering Deployments, Configuration Profiles, Datasources, Messaging, and Transactions and preserve the verified result in the JBoss EAP administration baseline, deployment and resource records, monitoring checklist, and recovery runbook.

1. Confirm scope, prerequisites, versions, identities, dependencies, and acceptance criteria.
2. Execute the workflow while recording commands, settings, outputs, events, and system messages.
3. Test normal behavior, one boundary condition, and the stated exception.
4. Document corrections, evidence, ownership, retest criteria, rollback, and handover actions.

Scenario Analysis

• Identify which object, service, policy, setting, or sequence most strongly influences deployment management.
• Compare two defensible responses and explain technical, security, operational, and support trade-offs.
• Determine how the JBoss EAP administration baseline, deployment and resource records, monitoring checklist, and recovery runbook should be approved, retained, retested, and updated.

Troubleshooting Guidance

Start where expected behavior first differs from the observed result. Check prerequisites, identity, configuration order, version compatibility, connectivity, status, resource limits, and evidence separately. Treat “a change succeeds in one environment but fails elsewhere because inventory, policy, version, or runtime assumptions differ” as a hypothesis until commands, logs, settings, and retest outcomes confirm the cause.

Validation Checklist

• Required platform components, identities, permissions, settings, and dependencies are present.
• The JBoss EAP administration baseline, deployment and resource records, monitoring checklist, and recovery runbook connects each conclusion to objective, reviewable evidence.
• Normal processing, a boundary condition, dependency behavior, and the stated exception were tested.
• Corrections, ownership, retest criteria, rollback, documentation, and operational handover are complete.

Lesson Outcome

Learners can apply Deployments, Configuration Profiles, Datasources, Messaging, and Transactions, explain the resulting platform behavior, and defend the outcome through the JBoss EAP administration baseline, deployment and resource records, monitoring checklist, and recovery runbook.
