Overview of Application Server Enterprise Edition

The Sun Java System Application Server Enterprise Edition 8 provides a robust J2EE platform for the development, deployment, and management of enterprise applications. Key features include transaction management, performance, scalability, security, and integration. The Application Server supports services from Web publishing to enterprise-scale transaction processing.

The Application Server is available in the Platform and Enterprise editions. The Platform edition is free and is intended for software development and department-level production environments. Designed for mission-critical services and large-scale production environments, the Enterprise edition supports horizontal scalability and service continuity via a load balancer plug-in and cluster management.

Overview of BEA WebLogic Server Clusters

The BEA WebLogic Server™ product uses the following definitions:

Domain. An interrelated set of WebLogic Server resources managed as a unit. A domain includes one or more WebLogic Servers, and might include WebLogic Server clusters.

Administration Server. A WebLogic Server running the Administration Service. The Administration Service provides the central point of control for configuring and monitoring the entire domain. The Administration Server must be running to perform any management operation on that domain.

Managed Server. In a domain with multiple WebLogic Servers, only one server is the Administration Server; the other servers are called Managed Servers. Each WebLogic Managed Server obtains its configuration at startup from the Administration Server.
