Common Domain Types
There are two basic types of domains:
! Domain with Managed Servers: A simple production environment can consist
of a domain with several Managed Servers that host applications, and an
Administration Server to perform management operations. In this configuration,
applications and resources are deployed to individual Managed Servers;
similarly, clients that access the application connect to an individual Managed
Server.
Production environments that require increased application performance,
throughput, or availability may configure two or more of Managed Servers as a
cluster. Clustering allows multiple Managed Servers to operate as a single unit to
host applications and resources. For more information about the difference
between a standalone and clustered Managed Servers, see “Managed Servers and
Clustered Managed Servers” on page 2-4.
! Standalone Server Domain: For development or test environments, you may
want to deploy a single application and server independently from servers in a
production domain. In this case, you can deploy a simple domain consisting of a
single server instance that acts as an Administration Server that, and also hosts
the applications you are developing. The examples domain that you can install
with WebLogic Server is an example of a standalone server domain.
Note: In production environments, BEA recommends that you deploy applications
only on Managed Servers in the domain; the Administration Server should be
reserved for management tasks.
