Using WebSphere Application Server V5 for Load Balancing and Failover , http://www.ibm.com/developerworks/library/i-wasldbal/>. (This is an excellent , short, step-by-step example that shows how to set up and test a cluster using a sample application shipped with WAS.)
WAS V5 Getting Started, ftp://ftp.software.ibm.com/software/ webserver /appserv/library/wasv5base_gs.pdf>. (This PDF manual has detailed instructions for installing the WAS base product.)
WAS ND V5 Getting Started, ftp://ftp.software.ibm.com/software/webserver/appserv/library/wasv5nd_gs.pdf>. (This PDF manual has detailed instructions for installing the Deployment Manager and setting up a cell and cluster. Unfortunately, the explanations aren't always that clear.)
WAS V5.0 System Management and Configuration, http://publib-b.boulder.ibm.com/Redbooks.nsf/RedbookAbstracts/sg246195.html?Open>. (Excellent IBM Redbook with installation and configuration instructions and helpful advice on choosing the right topology and configuration.)

Server Clusters for High Availability in WebSphere Application Server Network Deployment Edition 5.0, http://www.ibm.com/support/docview.wss?uid=swg27002473>. (Very broad coverage of HA topics with some helpful definitions and best practices.)
Implementing a Highly Available Infrastructure for WebSphere Application Server Network Deployment, Version 5.0 without Clustering, http://www7b.boulder.ibm.com/webapp/dd/transform.wss?URL=/wsdd/library/techarticles/0304_alcott/alcott.xml&xslURL=/wsdd/xsl/document.xsl&format=one-column. (If you have only a single system on which to run WAS, this article provides advice on maximizing availability using WAS ND. The main idea is protecting against extended unavailability of the Deployment Manager.)
