WebSphere Application Server Administration

Description

The IBM WebSphere Edge Components include several components residing at the "edge" of the network. They can work with pure webservers or with WebSphere Application Servers at the backend.

One component is the Dynamic Load Balancer. One part of the Load Balancer, the Network Dispatcher, uses an Advisor daemon at each server to determine current load on the server machine. It uses this information to dynamically redirect client access to the least busy machine. The Load Balancer interfaces with popular routers such as Cisco and Nortel. The Load Balancer also includes Content Based Routing (CBR) which routes client requests to an appropriate group of servers based on the URL content. This allows different servers to handle different parts of the web application.

Another component is the Caching Proxy which is suitable for either a Forward Proxy, between the client browser and the internet, or a Reverse Proxy, between the internet and the servers. This can work with a CBR plugin component for content-based routing.

The Site Selector component is the equivalent of an intelligent DNS server for relaying requests to back-end servers.

This course is highly hands-on. 60% of the time will be spent on doing labs.

Objectives

Upon completion of the course, students will be able to:

Plan for a successful deployment of the Edge Components
Install and configure the Edge Component as a Forward (or client) Proxy
Install and configure the Edge Component as a Reverse (or server) Caching Proxy
Tune the Caching Proxy
Install and configure the Network Dispatcher
Install and configure Content Based Routing (CBR)
Install and configure the Site Selector Component
Administer and Troubleshoot the Load Balancer
