Oracle WebLogic Server 14c: Performance Tuning Workshop — Lesson 3: JDBC, HTTP, Clusters, JMS, Network, and Application Resource Tuning

Learning Objectives

• Explain the purpose and operating context of JDBC pool sizing, reserve time, statement cache, leaks, and database waits.
• Apply HTTP channels, keep-alive, compression awareness, sessions, and front-end proxies and cluster replication, load balancing, serialization, and failover overhead in a controlled environment.
• Validate outcomes and troubleshoot risks involving JMS consumers, batching, persistence, stores, paging, and message backlog.

Detailed Topics

• JDBC pool sizing, reserve time, statement cache, leaks, and database waits
• HTTP channels, keep-alive, compression awareness, sessions, and front-end proxies
• cluster replication, load balancing, serialization, and failover overhead
• JMS consumers, batching, persistence, stores, paging, and message backlog

Instructor Demonstration

Demonstrate JDBC pool sizing, reserve time, statement cache, leaks, and database waits for a WebLogic application benchmarked and tuned against response-time and throughput objectives; 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: Performance Tuning Workshop exercise covering HTTP channels, keep-alive, compression awareness, sessions, and front-end proxies and cluster replication, load balancing, serialization, and failover overhead; introduce an exception involving JMS consumers, batching, persistence, stores, paging, and message backlog, 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 JDBC pool sizing, reserve time, statement cache, leaks, and database waits, HTTP channels, keep-alive, compression awareness, sessions, and front-end proxies, cluster replication, load balancing, serialization, and failover overhead, JMS consumers, batching, persistence, stores, paging, and message backlog 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, HTTP, Clusters, JMS, Network, and Application Resource Tuning in a realistic Oracle WebLogic Server 14c: Performance Tuning Workshop scenario and defend the result with documented evidence.
