Oracle WebLogic Server is a Java Platform with scalable Application Server. The WebLogic Server infrastructure supports the deployment of many types of distributed applications and is an ideal foundation for building applications based on Service Oriented Architectures (SOA).
Oracle WebLogic Server 11g is a component of Oracle Fusion Middleware 11g, which consists of several Oracle products that span business intelligence, collaboration tools, content management, and integration services.
Oracle offers three distinct products as part of the Oracle WebLogic Server 11g application family:
• Oracle WebLogic Server Standard Edition (SE)
• Oracle WebLogic Server Enterprise Edition (EE)
• Oracle WebLogic Suite
Components for WebLogic Server Administration
• WebLogic Domain Structure
• Administration Server
• Managed Servers
• High Availability
• Diagnostic Framework
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.
