1 Introduction

This chapter provides an overview of how to use Oracle Application Server Adapter (OracleAS Adapter). It contains the following topics:

Oracle Application Server Adapter Overview
Oracle Application Server Adapter System Requirements

1.1 Oracle Application Server Adapter Overview

The OracleAS Adapter enable you to integrate packaged, legacy, and mainframe applications with the Oracle Application Server components displayed in Table 1-1.

Table 1-1 Oracle Application Server Component Integration with OracleAS Adapter

Component	Description
OracleAS Integration InterConnect	Enables you to integrate heterogeneous systems such as Oracle applications, non-Oracle applications, and third-party, messaging-oriented middleware (MOM). OracleAS Integration InterConnect is a high-speed message broker that is suited for data and application integration. Integrations can be deployed within an enterprise or across enterprise boundaries through the Internet.
Oracle Application Server Portal	Combines a declarative environment for creating a portal Web interface, publishing and managing information, accessing dynamic data, and customizing the portal experience, with an extensible framework for J2EE-based application access. Using OracleAS Portal, organizations can provide employees, partners, and suppliers with the information they need and the flexibility to create views tailored to each community.
Oracle Application Server Containers for J2EE (OC4J)	The J2EE server component of Oracle Application Server written entirely in Java that runs on the standard Java Development Kit (JDK) Java Virtual Machine (JVM). OC4J includes a JSP Translator, a Java servlet container, and an Enterprise JavaBeans container.

You can use OracleAS Adapter with the Oracle Application Server components shown in Table 1-1. All Oracle Application Server adapters are included on a single CD-ROM. The OracleAS Adapter CD-ROM consists of adapters for packaged applications.

Table 1-2 describes the packaged adapters available for installation. OracleAS Adapter for packaged applications can be deployed as:

A J2CA 1.0 Resource Adapter, which is known as OracleAS Adapter JCA
A Web Services Servlet within the OC4J container, which is known as OracleAS Adapter Business Services Engine

The OracleAS Adapter Application Explorer graphical user interface tool (GUI) is also provided for configuring OracleAS Adapter JCA version 1.0 and OracleAS Adapter Business Services Engine.

Table 1-2 OracleAS Adapter for Packaged Applications

Type	Description
OracleAS Adapter for J.D. Edwards OneWorld XE	Links the processes of various applications with J. D. Edwards OneWorld's ERP, CRM, or B2B application solutions
OracleAS Adapter for PeopleSoft	Enables integration with PeopleSoft Release 8 application systems
OracleAS Adapter for SAP R/3	Enables access to R/3 Remote Function Call modules (RFCs), BAPI modules, and ALE Intermediate DOCuments (IDOCs)
OracleAS Adapter for Siebel	Integrates Siebel eBusiness 2000 Enterprise Edition with heterogeneous enterprise applications

Two OracleAS Adapter installation types are available. After selecting an installation type during installation, you select the type of adapter you want to install. Table 1-3 describes these installation types.

Table 1-3 Installation Types

Installation Type	Description
Complete	Installs the following OracleAS Adapter design time and runtime components: Design time components Installs the OracleAS Adapter Application Explorer design time component for browsing and extracting Enterprise Information System (EIS) metadata. In addition, OracleAS Adapter JCA version 1.0 and OracleAS Adapter Business Services Engine are configured. Runtime components Deploys the following runtime components automatically: OracleAS Adapter JCA version 1.0 for integration with OC4J OracleAS Adapter Business Services Engine for integration with OracleAS Portal and OracleAS Integration InterConnect OracleAS Adapter JCA version 1.0 test servlet Note: The Complete installation type must be installed in the same directory in which the J2EE and Web Cache Middle Tier installation type is already installed.
Design time	Installs only the OracleAS Adapter Application Explorer design time component. Use this component to configure the OracleAS Adapter JCA version 1.0 and OracleAS Adapter Business Services Engine. The runtime components are not deployed. Note: This installation type does not require J2EE and Web Cache or any other Middle Tier installation type.

Installation Type

Description

Complete

Installs the following OracleAS Adapter design time and runtime components:

Design time components

Installs the OracleAS Adapter Application Explorer design time component for browsing and extracting Enterprise Information System (EIS) metadata. In addition, OracleAS Adapter JCA version 1.0 and OracleAS Adapter Business Services Engine are configured.
Runtime components

Deploys the following runtime components automatically:
- OracleAS Adapter JCA version 1.0 for integration with OC4J
- OracleAS Adapter Business Services Engine for integration with OracleAS Portal and OracleAS Integration InterConnect
- OracleAS Adapter JCA version 1.0 test servlet

Note: The Complete installation type must be installed in the same directory in which the J2EE and Web Cache Middle Tier installation type is already installed.

Design time

Installs only the OracleAS Adapter Application Explorer design time component. Use this component to configure the OracleAS Adapter JCA version 1.0 and OracleAS Adapter Business Services Engine. The runtime components are not deployed.

Note: This installation type does not require J2EE and Web Cache or any other Middle Tier installation type.

1.2 Oracle Application Server Adapter System Requirements

The following sections describe the OracleAS Adapter system requirements:

Hardware Requirements
Software Requirements

1.2.1 Hardware Requirements

Table 1-4 lists the hardware requirements for the computer where OracleAS Adapter will be installed.

The following sections describe the OracleAS Adapter software requirements:

Operating System Requirements
J2EE and Web Cache Requirements

Operating System Requirements

Table 1-5 lists the operating system requirements for the computer where OracleAS Adapter will be installed.

Table 1-5 Operating System Requirements

Operating System	Version
HP Tru64	HP Tru64 UNIX (Alpha) 5.1b
HP-UX	HP-UX (PA-RISC) 11.11, 11.23
IBM AIX	AIX (POWER) version 5.2
Linux (x86)	Red Hat Enterprise Linux 2.1, 3.0 SuSE SLES8, SLES9 See Also: Oracle Application Server Installation Guide for Linux x86 for information about any required operating system patches and packages and kernel parameter settings
Sun SPARC Solaris	Sun SPARC Solaris 8 and 9 See Also: Oracle Application Server Installation Guide for Solaris for information about any required operating system patches and packages, swap space requirements, and kernel parameter settings

J2EE and Web Cache Requirements

If you want to use the Complete installation type, then the J2EE and Web Cache installation type of Oracle Application Server must first be installed. You then install the Complete installation type of OracleAS Adapter into the same Oracle home.

The design time installation type does not require J2EE and Web Cache or any other Middle Tier installation type.

Note:

OracleAS Adapter can be installed before or after you install OracleAS Integration InterConnect, OracleAS Portal, and OC4J.
The plugin that is required to use OracleAS Adapter with OracleAS Integration InterConnect is not available on this CD-ROM. The OracleAS Integration InterConnect Adapter Plugin for EIS is available on the OracleAS Integration InterConnect CD-ROM. Refer to Oracle Application Server InterConnect Installation Guide for installation instructions.
