|Oracle® Warehouse Builder Installation and Administration Guide
11g Release 2 (11.2) for Windows and Linux
Part Number E17130-03
This section discusses the architecture and components of Oracle Warehouse Builder and provides installation and configuration procedures.
This section includes the following topics:
Depending on the business needs of your organization, you may be implementing different types of Oracle Warehouse Builder installations:
The primary installation of Oracle Warehouse Builder, which includes the installation and configuration of the main design repository.
Optional installations on client computers where developers and administrators run Oracle Warehouse Builder client software, which do not contain a repository.
Optional installations on hosts that run the Control Center Agent service, but do not contain a repository.
Optional installations on database server hosts, where ETL jobs execute and where the repository stores only run-time data.

Chapter 2, "Installing Oracle Warehouse Builder on the Server" for the software installation tasks
This section describes some common installation configurations, and shows how the various components interact. The primary Oracle Warehouse Builder components include:
See Also:Oracle Warehouse Builder Concepts for conceptual information about Warehouse Builder components
Depending on your business needs, there are many possible installation configurations. The five most common topologies, which are illustrated in this section, are:
Note:in any of these topologies, it is typical to have multiple design clients. For example, each OWB developer or administrator usually has a corresponding, installed OWB client, also called a design client.
When everything is running on the same computer, the database home for Oracle Database 11g Release 2 contains all the components needed to run Warehouse Builder, as illustrated in Figure 1-1.
Figure 1-1 Single Computer Topology for Oracle Database 11g Release 2
If separate computers are being used to run the client and to host the repository, then all computers must have the OWB software installed, as illustrated in Figure 1-2. For the database server installation, Oracle Database 11g Release 2 includes the necessary components. For the client, you must install the OWB software from the standalone install image.

If a database on a separate computer is being used to run mappings designed on another database, then all computers must have the OWB software installed, as illustrated in Figure 1-3. For the database servers, the installation for Oracle Database 11g Release 2 includes the necessary components. For the client, you must install the OWB software from the standalone install image.
You must prepare the OWB repository on all database server computers. As illustrated in Figure 1-3, one acts as the design repository (Server1). The additional servers where mappings execute each have their own repository (shown as Server2), which in this case functions as a run-time repository. The Control Center Service on the execution database server deploys and executes the code.
Figure 1-3 Multiple Database Topology
If the OWB client, the Control Center Service, and the repository run on different computers, then all these computers must have the OWB software installed, as illustrated in Figure 1-4. For the database server, the installation media for Oracle Database 11g Release 2 includes the necessary components. For the client, you must install the OWB software from the standalone install image. For the Control Center Service, you can use either type of installation. However, Oracle recommends that you use the standalone image because it installs only the components that OWB requires.
Figure 1-4 Separate Client, Control Service Center, and Database Server Topology
If separate computers are used to run the OWB client, the Control Center Agent service (CCA), and the repository, then all computers used to deploy or execute OWB code must have installed OWB software, as illustrated in Figure 1-5. For the database server, the installation for Oracle Database 11g Release 2 includes the necessary components. For the client, you must install the OWB software from the standalone install image. For the Control Center Agent service, you can use either install. However, because the standalone image only installs the OWB-required components, Oracle recommends this option.
In some deployments, a Control Center Service is required on a host that does not have an Oracle Database installed. For example, if you use code template-based ETL mappings where part of the mapping executes on a non-Oracle database, then you can run a Control Center Agent on that non-Oracle database host. In such a case, you can install the OWB software on the non-Oracle database host.
Also note that:
On the non-Oracle database host, the only component of the OWB software that is used is the Control Center Agent. The rest of the software is present but not used.
The CCA may be located with the OWB client or Server1, in which case no additional installation would be necessary.
In Figure 1-5, the Map1 has three execution units (a, b, c). The first two are Load Code Templates (LCTs) and the other one is an Oracle Target Code Template.
