Oracle Fusion Middleware Integration Terminology

Term Definition
IdM Configuration Tool A command-line tool to verify the status of identity management components and to perform certain integration tasks.
Oracle Access Protocol (OAP) A secure channel for communication between Webgates and Access Manager servers during authorization.
Oracle Fusion Middleware home A Middleware home consists of the Oracle WebLogic Server home, and, optionally, one or more Oracle homes.

A Middleware home can reside on a local file system or on a remote shared disk that is accessible through NFS.

Oracle HTTP Server (OHS) Web server component for Oracle Fusion Middleware that provides a listener for Oracle WebLogic Server.
WebLogic Server home A WebLogic Server home contains installed files necessary to host a WebLogic Server. The WebLogic Server home directory is a peer of other Oracle home directories underneath the Middleware home directory.
Oracle home An Oracle home contains installed files necessary to host a specific product. For example, the Oracle Identity Management Oracle home contains a directory that contains binary and library files for Oracle Identity Management.

An Oracle home resides within the directory structure of the Middleware home. Each Oracle home can be associated with multiple Oracle instances or Oracle WebLogic Server domains.

Oracle instance An Oracle instance contains one or more system components, such as Oracle Web Cache, Oracle HTTP Server, or Oracle Internet Directory. The system components in an Oracle instance must reside on the same machine. An Oracle instance directory contains files that can be updated, such as configuration files, log files, and temporary files.

An Oracle instance is a peer of an Oracle WebLogic Server domain. Both contain specific configurations outside of their Oracle homes.

The directory structure of an Oracle instance is separate from the directory structure of the Oracle home. It can reside anywhere; it need not be within the Middleware home directory.

Oracle WebLogic Server domain A WebLogic Server domain is a logically related group of Java components. A WebLogic Server domain includes a special WebLogic Server instance called the Administration Server, which is the central point from which you configure and manage all resources in the domain. Usually, you configure a domain to include additional WebLogic Server instances called Managed Servers. You deploy Java components, such as Web applications, EJBs, and Web services, and other resources to the Managed Servers and use the Administration Server for configuration and management purposes only.

Managed Servers in a WebLogic Server domain can be grouped together into a cluster.

An Oracle WebLogic Server domain is a peer of an Oracle instance. Both contain specific configurations outside of their Oracle homes.

The directory structure of an WebLogic Server domain is separate from the directory structure of the WebLogic Server home. It can reside anywhere; it need not be within the Middleware home directory.

system component A system component is a manageable process that is not WebLogic Server. For example: Oracle HTTP Server, WebCache, and Oracle Internet Directory. Includes the JSE component.
Java component A Java component is a peer of a system component, but is managed by the application server container. Generally refers to a collection of applications and resources, with generally a 1:1 relationship with a domain extension template. For example: SOA and WebCenter Spaces.
Oracle Fusion Middleware farm Oracle Enterprise Manager Fusion Middleware Control is a Web browser-based, graphical user interface that you can use to monitor and administer an Oracle Fusion Middleware farm.

An Oracle Fusion Middleware farm is a collection of components managed by Fusion Middleware Control. It can contain WebLogic Server domains, one or more Managed Servers and the Oracle Fusion Middleware system components that are installed, configured, and running in the domain.

Oracle Identity Management The suite of identity and access management components in Oracle Fusion Middleware. See Section 1.3 for details.
WebLogic Administration Server The Administration Server is the central point from which you configure and manage all resources in the WebLogic domain.
WebLogic Managed Server The Managed Server is an additional WebLogic Server instance to host business applications, application components, Web services, and their associated resources. Multiple managed servers can operate within the domain. Certain Managed Servers in the domain are created specifically to host Oracle Fusion Middleware components.
