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.
