Partitioning and Clustering Demonstration Improve performance for Web and application deployment with Borland Enterprise Server ®
by Joe Overton, U.S. Systems Engineer, Borland Software Corporation
Introduction Rapidly changing business requirements mean corporations must roll out e-business applications faster than ever before. Modern Web applications require a solid deployment platform that supports rich, dynamic content and provides the tools necessary to implement caching, session management, and the database needs of real-world applications. The Borland® Enterprise Server is one of the most reliable and scalable J2EE™ application servers available, with sophisticated clustering, load balancing, fault tolerance, and fail-over. This paper offers demonstrations of clustering and partitioning with the Borland Enterprise Server.

Configuring partitions
Right-click on the partitions folder and select New partition.
Every partition can have its own unique configuration details. This allows multiple J2EE applications to run in an isolated environment within one Borland Enterprise Server. When making configuration changes to the partition services, the console will prompt the user to restart the partition. It is recommended that the user decline the restart until all configurations have been made. Enter a name for the partition and select OK. It is required to change the port number the Web container uses before running a new partition. Right-click on Web container A new partition is created based on the default located at:
and select configure.

Change the port number in the section that reads: The partition is idle (stopped) upon creation. 2
