This redbook discusses various options for scaling applications based on WebSphere Application Server, Advanced Edition. The objective of this book is to explore how the basic configuration can be extended to provide more computing power, by better exploiting the power of each machine, and by using multiple machines. It examines a number of techniques, including:
Cloning and Pooling of multiple Java Virtual Machines
Distributing the load from one Web server to multiple Application Servers, using Servlet Redirector and OSE Transports
Using IBM Network Dispatcher to distribute the load between multiple Web servers
Using the EJB Workload Management facility (WLM) to distribute load at the EJB level
Distributing session state using the Session Clustering Facility
This book shows step-by-step procedures for the UNIX, Windows NT and AS/400 platforms. Both simple and advanced configurations are covered.
This has been done using WebSphere Application Server V3.021 (OS/400, UNIX and Windows NT) and V3.5 (UNIX and Windows) Advanced Edition.
