1 Installation Overview

Oracle Web Tier contains two main components: Oracle HTTP Server and Oracle Web Cache. Oracle Process Manager and Notification Server (OPMN) is also installed by default. Together, these products are responsible for managing incoming HTTP requests, caching web messages, and sending XML and HTML back to the client.

The Oracle Web Tier installation will give you the option of installing Oracle HTTP Server and Oracle Web Cache. Oracle Process Manager and Notification Server is automatically installed and you will not have the option to de-select this product.

The chapter includes the following sections:

1.1 Oracle Web Tier Components

Oracle Web Tier contains the following components:

For more information about these components, refer to Oracle Fusion Middleware Concepts.

1.2 Installation Roadmap

Figure 1-1 shows the directory structure of a simple Oracle Web Tier installation on a single host, using all of the default values.

Figure 1-1 Directory Structure of Oracle Web Tier Installation

Description of Figure 1-1 follows
Description of "Figure 1-1 Directory Structure of Oracle Web Tier Installation"


Although Oracle WebLogic Server is not required in order to complete an Oracle Web Tier installation, the directory structure for the Middleware home must still be present. This is to make the directory structure for Oracle Web Tier consistent with other Oracle Fusion Middleware products, all of which require the existence of WebLogic Server and its corresponding directory structure.

In the case of an Oracle Web Tier installation in non-managed mode, the directory structure will still be created despite the absence of Oracle WebLogic Server.

Table 1-1 describes the high-level tasks for installing and configuring Oracle Web Tier. The table also provides information on where to get more details on each task.
