Oracle WebLogic Server 14c: Administration I — Lesson 3: JDBC Resources, Deployments, Clusters, and Availability

Technical Scope

• JDBC pools, JNDI, and connection tests
• application archives and deployment plans
• cluster members, replication, and load balancing
• deployment health, rollback, and availability checks

Instructor Demonstration

Demonstrate JDBC pools, JNDI, and connection tests inside a WebLogic application platform built from an empty host and operated through deployment and server failures, then capture the exact configuration, command, transaction, report, or code evidence that proves the result.

Applied Workshop

Implement a controlled workshop covering application archives and deployment plans and cluster members, replication, and load balancing, then test a failure or exception involving deployment health, rollback, and availability checks.

1. Confirm environment, identity, data, dependencies, and expected result.
2. Complete the product-specific implementation or analysis.
3. Capture commands, configuration, output, logs, transactions, or reports.
4. Explain the operational, security, performance, or business trade-off.

Validation Standard

The JDBC Resources, Deployments, Clusters, and Availability result must be reproducible, traceable to approved inputs, and consistent with the expected Oracle product behavior.

• The intended target and ownership are verified.
• The result is supported by reproducible evidence.
• Security, performance, reliability, and support impact are reviewed.
• Unexpected behavior is investigated before acceptance.

Failure Analysis

Diagnose issues in JDBC pools, JNDI, and connection tests, application archives and deployment plans, cluster members, replication, and load balancing, or deployment health, rollback, and availability checks without making an unverified production change.

Learners isolate the smallest proven cause, apply a reversible correction, rerun validation, and record the preventive action.
