What is WebLogic Domain Structure?

The basic administrative unit for a WebLogic Server is called a domain. A domain is a logically related group of WebLogic Server resources that you manage as a unit. A domain always includes the minimum of one instance called the Administration Server.

The Administration Server is a central point of contact for server instances and system administration tools. A domain may also include additional WebLogic Server instances called Managed Servers.

The domain can run in two modes:

1) Development mode: A domain running in development mode does not require a password during startup of the Administration Server. You also can do auto deploy of your applications, as some other parameters are not that strictly configured.

2) Production mode: Running in production mode needs passwords, encryption of files at a higher level, and some parameters within the resources (such as JDBC, JMS) are strictly configured.
