WEBSPHERE APPLICATION SERVER 8.0 ADMINISTRATION ON LINUX – GTWSP14

Course Description

This course teaches the basics of the administration and deployment of enterprise applications in the IBM WebSphere Application Server 8.0 Network Deployment environment. This course covers all of the topics required to administer a production WebSphere environment, including troubleshooting, security, databases, messaging, performance, scripting, web services, and clustering.

The labs for the course use a Linux environment. We have found that many WebSphere clients run WebSphere on Linux or some similar non-Windows environment. So learning how to administer WebSphere in this environment just makes sense.

Topics
  • Enterprise (Java EE) Applications
  • Installing and Configuring WebSphere Application Server
  • Installing Enterprise Applications
  • IBM HTTP Server Installation and Configuration
  • WebSphere Application Server Architecture
  • Application Tracing and Troubleshooting
  • Data Source Configuration and Management
  • Security Management
  • Java Messaging Service (JMS) Management
  • Performance Monitoring and Tuning
  • Scripting of Administrative Activities
  • Web Service Administration
  • Clustered Workload Management
What you will learn
After completing this course, the student should be able to:

  • Install and configure WebSphere Application Server
  • Install, configure and manage enterprise applications
  • Configure web server integration
  • Assemble enterprise modules into applications
  • Use various troubleshooting tools and techniques to diagnose problems
  • Configure database connections
  • Configure runtime security
  • Install and configure messaging applications
  • Analyze and tune the performance of enterprise applications
  • Perform basic administrative tasks using scripting
  • Configure a cluster of WebSphere Application Servers

Target Audience

This course is designed for Webmasters and System Administrators who need to install, configure and maintain systems using WebSphere Application Server 8.0 Network Deployment Edition.

^^

Course Prerequisites

The student should have a good understanding of Web technology, Java, and operational skills for Linux. Administration skills for a web server like Apache or IBM HTTP Server would also be beneficial although not required.
