Oracle Application Server 10g Essentials [Electronic resources] نسخه متنی

1.2 The Oracle Application Server Family

Oracle Application Server
10g is the name of the most recent major version
of the
Oracle Application Server family of
products. These products all share common source code. The family
includes the following packages:

Oracle Application Server Java Edition

A version targeted for
Java developers.

Oracle Application Server Standard Edition

A version targeted for deployment requiring less middle-tier
functionality.

Oracle Application Server Enterprise Edition

A version targeted for more complex
deployment. This version offers additional functionality, including
business intelligence and integration components and the OracleAS

Personalization and OracleAS Wireless
features.

At the time of this writing, these were the only packages available for Oracle Application Server. If additional packages or bundles are offered, we'll provide updates on the web page for this book (see the Preface).

Oracle focuses development around a single source-code model for all
its products, including Oracle Application Server. The Oracle
Application Server releases are available today on Windows,
RedHat and SuSE Linux,
and on Unix platforms such as HP Compaq Tru64, HP/UX, IBM AIX, and
Sun Solaris. Because features are consistent across platforms for
implementations of Oracle Application Server, companies can migrate
easily to various hardware vendors and operating systems while
leveraging their investments in Oracle technology. This development
strategy also enables Oracle to focus on implementing new features
only once in its product set, instead of having to add functionality
at different times to different implementations.

Oracle Application Server 10g includes a
web listener based on the popular
Apache Web
Server distribution. It also includes support for

Java 2 Enterprise
Edition (J2EE) containers and a JavaServer Pages (JSP)
translator, as well as business logic and data access technologies.
Business logic may be enabled through
JavaBeans© and Enterprise JavaBeans (EJBs).
Data access technologies may include Java
DataBase Connectivity (JDBC), SQLJ, EJBs, and J2EE resource adapters.
Finally, Oracle Application Server also provides the infrastructure
needed for developing, deploying, and managing Web Services.

Every Oracle Application Server edition also includes
Oracle Enterprise Manager
10g Application Server Control, a tool used for
configuring and managing each server. Another tool, Oracle Enterprise
Manager 10g Grid Control, is used to manage
multiple Oracle Application Servers and can provide a single point of
access to each Application Server Control installed with multiple
servers. The Grid Control software is installed from a separate Grid
Control CD.

The following sections briefly describe each
Oracle Application Server edition. At
this point, we won't attempt to explain the features
mentioned here. You will find more detailed information in Section 1.3.

1.2.1 Oracle Application Server Java Edition

Oracle Application Server
Java Edition is a
specific Oracle Application Server package created by Oracle for
developers of Java-based software who aren't
interested in the deployment features available in other Oracle
Application Server editions. The Java Edition bundle includes the
following:

Oracle HTTP Server

Oracle Application Server
Containers for J2EE (OC4J)

Oracle Business Components for Java (BC4J)

Oracle Application Server TopLink

Oracle JDeveloper named user licensing

This edition is the least expensive version of Oracle Application
Server.

1.2.2 Oracle Application Server Standard Edition

In
terms of functionality and pricing, Oracle Application Server
Standard Edition is packaged to compete
in the entry-level category for application servers. The Standard
Edition adds the following components to features previously noted
for the Java Edition:

Oracle Application Server Portal

Oracle Application Server Single
Sign-On security

Oracle Application Server Content
Management Software Development Kit (SDK)

A restricted-use Oracle Internet Directory is provided in the
Standard Edition to enable OracleAS Single Sign-On.

1.2.3 Oracle Application Server Enterprise Edition

Oracle Application Server Enterprise
Edition is aimed at larger-scale implementations that require
additional features. Enterprise Edition adds the following features
to those available in the Java Edition and the Standard Edition:

OracleAS Forms Services and OracleAS Reports Services

OracleAS Discoverer

Oracle Internet Directory

Oracle Workflow

Oracle Application Server InterConnect and Oracle Application Server
ProcessConnect

OracleAS Personalization

OracleAS Wireless

Before Oracle Application Server 10g, OracleAS
Personalization and OracleAS Wireless, described next, were available
only as options.

OracleAS
Personalization

This feature provides a means by which a web server can gather data
on how a web-site visitor traverses the site. This data is sent to an
Oracle database where a taxonomy describing the business and business
goals is defined. Analysis of this data occurs periodically using
data mining algorithms in the database, and recommendations are
created. These recommendations are populated in middle-tier
"recommendation engines" that can
redirect web-site users to
"personalized" web pages of
material that are likely to interest them.

OracleAS Wireless

This feature provides an integrated set of capabilities enabling
multichannel mobile access, including voice, to applications. At the
core of OracleAS Wireless is support of HTTP and XML. OracleAS
Wireless enables the building of portlets that can be displayed on
wireless devices. It also provides mobile services such as personal
information management (PIM) and email, and location-based and
two-way messaging services.
