Installing and Configuring Oracle Web Tier
Purpose
This tutorial describes and shows you how to install and configure the Oracle Web Tier Instance.
Time to Complete
Approximately 30 minutes.
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.
- Oracle HTTP Server: Oracle HTTP Server provides a listener for Oracle WebLogic Server and the framework for hosting static pages, dynamic pages, and applications over the Web. It is based on Apache 2.2.10 infrastructure, and includes modules developed specifically by Oracle. The features of single sign-on, clustered deployment, and high availability enhance the operation of the Oracle HTTP Server.
- Oracle Web Cache: Oracle Web Cache is a content-aware server accelerator, or reverse proxy, for the Web tier that improves the performance, scalability, and availability of Web sites that run on Oracle HTTP Server. Oracle Web Cache is the primary caching mechanism provided with Oracle Fusion Middleware. Caching improves the performance, scalability, and availability of Web sites that run on Oracle WebLogic Server by storing frequently accessed URLs in memory.
- Oracle Process Manager and Notification Server (OPMN): OPMN provides a command-line interface for you to monitor and manage Oracle Fusion Middleware components and sub-components. The OPMN server should be started as soon as possible after turning on the computer. OPMN must be running whenever OPMN-managed components are turned on or off.
The Oracle Web Tier installation gives you the option of installing Oracle HTTP Server and Oracle Web Cache. Oracle Process Manager and Notification Server is automatically installed and you do not have the option to de-select this product.
