1 Product and Installation Overview

This chapter describes what is contained in Oracle Application Server and recommended topologies. It contains the following sections:

Section 1.1, "Product Overview"
Section 1.2, "Basic and Advanced Installation"
Section 1.3, "Recommended Topologies"

1.1 Product Overview

Oracle Application Server 10g Release 3 (10.1.3.1.0) provides the Oracle SOA Suite, which is a complete set of service infrastructure components for creating, deploying, and managing Service Oriented Architectures. Oracle SOA Suite enables services to be created, managed, and orchestrated into composite applications and business processes.

Oracle SOA Suite consists of:

Oracle BPEL Process Manager
Oracle Enterprise Service Bus (ESB)
Oracle Web Services Manager (OWSM)
Oracle Business Rules
Oracle Application Server (includes Oracle HTTP Server, Oracle Containers for J2EE (OC4J or J2EE Server), Oracle Enterprise Manager 10g Application Server Control, Oracle Process Manager and Notification Server and OC4J Java Single Sign-On)

You can integrate Oracle Application Server 10g Release 3 (10.1.3.1.0) with an existing Oracle Application Server environment that includes 10g Release 2 (10.1.2) or 10g (10.1.4.0.1) OracleAS Infrastructure.

1.2 Basic and Advanced Installation

Table 1-1 summarizes the groups of services available with each installation type.

Table 1-1 Oracle Application Server 10g Release 3 (10.1.3.1.0) Install Types

Install Mode	Available Installation Types
Basic	J2EE Server and SOA Suite
Advanced	J2EE Server, Web Server, and SOA Suite J2EE Server and Web Server J2EE Server Web Server

The basic (one-click) installation prompts you with questions on the initial installation screen, and then it proceeds to install the product without any further user interaction. The default values for all the components are used.

The advanced installation provides you with a great degree of customization and flexibility, which enables installation of additional languages, port configuration options, and cluster configuration.

Table 1-2 summarizes the differences in the customization options between basic and advanced installation.
