To deliver application hosting, Web content, security, and integration, Oracle9i Application Server includes the following services and components that support a 100% Internet platform:

• Communication Services: These services handle all incoming requests received by Oracle9i Application Server. Some of these requests are processed by Oracle HTTP Server and some requests are routed to other areas of Oracle9i Application Server for processing.
• Presentation Services: These services deliver dynamic content to client browsers, supporting servlets, JavaServer Pages, Perl/CGI scripts, PL/SQL Pages, forms, and business intelligence.
• Caching Services: To reduce the load on the back-end database instance, and to avoid network roundtrips for read-only data, Oracle9i Application Server includes Oracle Database Cache (formerly Oracle8i Cache).
• Content Management Services: These services make all of your content, regardless of the file type, accessible in one heterogeneous file hierarchy via Web browsers, Microsoft Windows networking, or FTP. In addition, you can use these services to configure sophisticated file searching capability, event-triggered alerts, and check-in-check-out functionality to support collaborative projects.
• Portal Services: You can use these services to build portal sites that integrate all of your different types of content on a single Web page. Portal sites give your users a single, centralized, personalized view of relevant applications and data, accessible from both fixed and mobile clients.
• Business Intelligence Services: You can use these services to deploy and share business intelligence over the Web or over your corporate intranet to provide up-to-the-minute information.
• Developer's Kits: The toolkits included in Oracle9i Application Server contain libraries and tools to support application development and deployment.
• System Services: To provide system management and security services, Oracle9i Application Server provides a comprehensive management framework for your entire Oracle environment and network security via SSL (Secure Sockets Layer)-based encryption and authentication facilities.
