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

2.3 Installation Types

The complexity of the Oracle Application Server infrastructure
depends on the type of product installation. There are three Oracle
Application Server installation types:

J2EE and Web Cache

Portal and Wireless

Business Intelligence and Forms

Each installation type builds on its predecessor's
functionality; consequently, each requires a more complex
infrastructure.

2.3.1 J2EE and Web Cache

The J2EE and Web Cache installation
provides a high-performing and very scalable J2EE application server.
In the Enterprise Edition version of the Oracle Application Server
product, it consists of the following:

Oracle HTTP
Server

Oracle Application Server
Containers for J2EE

OracleAS Web Cache

Note, however, that OracleAS Web Cache isn't
included in the Java and Standard Editions.

This installation requires a DCM repository in which Oracle
Application Server configuration data can be stored. The repository
for this version can be either file-based or stored in an Oracle
database.

2.3.1.1 Portal and Wireless

The Portal and
Wireless
installation contains all the components of
the J2EE and OracleAS Web Cache installation. It also contains:

OracleAS Portal, a
complete, out-of-the-box, user-configurable portal solution

OracleAS Wireless, which allows you to use web-based applications on
mobile devices

Although this edition doesn't contain the following
components, it uses them at runtime, so the infrastructure has to
exist before you install this edition:

Identity Management

This infrastructure must exist in the form
of Oracle Application Server Single Sign-On product support; this
product allows your users to use one set of login credentials for all
applications running on the application server.

Oracle Internet Directory

This infrastructure is added to the Identity Management
infrastructure because Oracle Application Server Single Sign-On
requires an LDAP server.

Note that OracleAS Portal and OracleAS Wireless store their own
application data in the infrastructure's OracleAS
Metadata Repository.

2.3.1.2 Business Intelligence and Forms

The Business Intelligence and Forms
installation contains all the components available in the OracleAS
Portal and OracleAS Wireless installation, as well as the following
additional components:

OracleAS Discoverer

OracleAS Forms Services

OracleAS Reports Services

OracleAS Personalization

This installation doesn't add any more complexity to
the infrastructure because no additional infrastructure components
are required, but it does add more metadata. Like the Portal and
Wireless edition, the Business Intelligence and Forms edition uses a
preexisting infrastructure. However, there is also a standalone
installation for the Forms Server and Reports Server that
doesn't require an infrastructure.
