2-8 Oracle Fusion Middleware Concepts Guide
Oracle Fusion Middleware supports multiple repository types. A repository type represents a specific schema or set of schemas that belong to a specific Oracle Fusion
Middleware component for example, Oracle SOA Suite or Oracle Internet Directory.
A particular type of repository, the Oracle Metadata Services MDS repository, contains metadata for most Oracle Fusion Middleware components, such as Oracle
B2B, and for certain types of applications.
2.10 What is a Farm?
A farm is a collection of components managed by Fusion Middleware Control. It can contain Oracle WebLogic Server domains, one Administration Server, one or more
Managed Servers, and the Oracle Fusion Middleware components that are installed, configured, and running in the domain.
2.11 Oracle Fusion Middleware Directory Structure and Concepts
During the installation process, you are asked for a variety of directory locations. This section defines each of these directories and explains the contents of each directory.
This section includes the following topics:
■
Middleware Home and WebLogic Home Directories
■
Oracle Home Directory
■
WebLogic Domain
■
Multiple Products with Multiple Oracle WebLogic Server Domains
■
Domain Extension
■
Oracle Instance and Oracle WebLogic Server Domain
2.11.1 Middleware Home and WebLogic Home Directories
The top-level directory for all Oracle Fusion Middleware products is called the Middleware home; this directory is created when Oracle WebLogic Server is installed.
The WebLogic home directory is inside the Middleware home, and is also created when Oracle WebLogic Server is installed.
Figure 2–4 shows the directory structure
after a Oracle WebLogic Server installation.

Key Concepts 2-9
2.11.2 Oracle Home Directory
Each Oracle Fusion Middleware product must be installed in its own Oracle home location. The software binaries are installed into the Oracle home; no run time process
can write to this directory.
The Oracle home directories in this case, the SOA Oracle home for each product must reside inside an existing Middleware home directory see
Figure 2–5 .
Figure 2–5 Directory Structure with An Oracle Home Directory
The Oracle home directory can be created in the following ways:
■
Before running the installation, you can create your Oracle home directory on your system. Remember that the Oracle home must reside inside the Middleware
home directory, and it must also be an empty directory. Then, when you run the installer and are asked to provide the location of your Oracle home, you can
specify the directory you have created.
■
While running the installer, you can specify the name of a new directory. This directory are automatically be created for you by the installer and will be located
inside the Middleware home directory.
2.11.3 WebLogic Domain
After a product is installed, it can be configured into an Oracle WebLogic Server Domain see
Section 2.4, What Is an Oracle WebLogic Server Domain? .
The User Projects directory is created when you create or configure a domain in this case, a SOA domain. By default, new domains are created inside the Domains folder,
but you can choose to create these elsewhere.
