Oracle WebLogic Server 14c: Administration II — Lesson 4: WLST Automation, Diagnostics, Patching, Backup, Upgrades, and Operations

Learning Objectives

• Explain the purpose and operating context of WLST online and offline automation, configuration plans, and repeatability.
• Apply WLDF watches, notifications, diagnostic images, instrumentation, and incidents and domain backup, pack and unpack, rolling restart, patching, and rollback in a controlled environment.
• Validate outcomes and troubleshoot risks involving health checks, capacity, audit, documentation, and advanced administration runbook.

Detailed Topics

• WLST online and offline automation, configuration plans, and repeatability
• WLDF watches, notifications, diagnostic images, instrumentation, and incidents
• domain backup, pack and unpack, rolling restart, patching, and rollback
• health checks, capacity, audit, documentation, and advanced administration runbook

Instructor Demonstration

Demonstrate WLST online and offline automation, configuration plans, and repeatability 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 WLDF watches, notifications, diagnostic images, instrumentation, and incidents and domain backup, pack and unpack, rolling restart, patching, and rollback; introduce an exception involving health checks, capacity, audit, documentation, and advanced administration 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 WLST online and offline automation, configuration plans, and repeatability, WLDF watches, notifications, diagnostic images, instrumentation, and incidents, domain backup, pack and unpack, rolling restart, patching, and rollback, health checks, capacity, audit, documentation, and advanced administration 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 WLST Automation, Diagnostics, Patching, Backup, Upgrades, and Operations in a realistic Oracle WebLogic Server 14c: Administration II scenario and defend the result with documented evidence.
