Desktop Tier: Forms Client Applet

The Forms Client Applet is a presentation applet that:

• Supports Oracle Applications products that use the Forms interface

• Is packaged as Java Archive (JAR) files– The JAR files contain all classes required for Oracle

Applications– They are downloaded on demand and cached on the desktop

Application Tier: Load Balancing

• The Application tier supports load balancing among different service groups and servers

• Benefits include high availability, fault tolerance, reliability and scalability

• The same platform (such as Linux) should be used for all application tier machines


Application Tier: HTML-Based Applications

The HMTL-based (formerly, Self-Service) applications:

• Do not use Oracle Forms for the interface

• Are designed in pure HTML and JavaScript

• Dynamically generate HTML pages by executing Java code

• Use a metadata dictionary for flexible layout

• Operate by direct connection to the Web server


Application Tier: Oracle Applications Framework

• Oracle Applications Framework is a Java-based application tier development and deployment platform for HTML-based applications

• Framework-based applications logic is controlled by procedures that execute through the Java Servlet Engine


Application Tier: Oracle Applications Framework Components

Oracle Applications Framework uses various components, including:

• AOL Java (AOL/J)

• Business Components for Java (BC4J)

• Java Controller

• Metadata UI Definition

• UIX HTML Generator

Application Tier: Network Traffic

To minimize network traffic:

• JAR files for the Forms client applet are downloaded automatically the first time it is used, and subsequently cached on the desktop PC

• The browser (with J2SE plug-in) will automatically retrieve new JAR files if they have changed on the application tier


Application Tier: Network Traffic

For optimum runtime network usage:

• Many operations can performed without contacting the Forms services at all

• When tabbing through fields, only one round trip per field is needed

• Compact messages communicate user events and corresponding screen updates

The Report Review Agent allows:

• Online viewing of report log and output files

• Viewing of reports one page at a time

• Storage of report output on the concurrent processing node

Oracle Homes

Oracle Applications Release 12 utilizes three Oracle homes:

• Oracle 10g Release 2 RDBMS ORACLE_HOME:– Used by the Oracle database server

• Application Server 10.1.2 ORACLE_HOME:– Known as the Tools, C, or Developer ORACLE_HOME– Replaces the 8.0.6 ORACLE_HOME in Release 11i

• Application Server 10.1.3 ORACLE_HOME:– Known as the Web or Java ORACLE_HOME– Replaces the iAS ORACLE_HOME in Release 11i


Oracle Homes

• The three Oracle Homes fit into the architecture as follows:


Oracle Applications Technology Layer

The Oracle Applications technology layer is an integrated collection of components that are used by all Oracle Applications modules:

Manufacturing

Oracle Applications Technology Layer

CRM Financials HRMS ...

The various components of the Applications Technologylayer are discussed on the following slides.


Oracle Applications DBA (AD)

Oracle Applications DBA provides a range of administration utilities used for installing, upgrading, maintaining, and patching an Applications system:

• AD Administration

• AD Merge Patch

• AutoConfig

• AutoPatch

• Rapid Clone

• Rapid Install


Oracle Application Object Library (FND)

Oracle Application Object Library is a collection of reusable code, programs, and database objects that provides common functionality across all products:


Oracle Application Object Library:End User Features

Oracle Application Object Library includes features that provide uniformity across Applications products:

• Standard user interface

• Shared flexfield value sets

• Standard Report Submission (SRS)

• Applications Online Help

• User profiles


Oracle Application Object Library: Developer Features

Various Applications features can be utilized when creating custom forms, reports or programs:

• GUI and coding standards– As used by Oracle Development

• Standard Report Submission– Custom reports can be submitted using SRS

• Flexfield development– Custom forms can utilize standard capabilities

• Custom menus and responsibilities– Can be integrated with Oracle Applications


Oracle Application Object Library: System Administration Features

• Set up new Oracle Applications users

• Manage and control security

• Audit user activity

• Set user and system profiles

• Manage concurrent processing

Oracle Applications Utilities (AU)

AU is used to maintain an Applications system:

• AU hosts certain product files in a central location– For example, Forms source files (.fmb)

• This allows generating on-site classes of files such as Forms and reports

• Generating forms or reports may require access to shared PL/SQL libraries

– These are also copied to AU_TOP


Oracle Applications Framework (OAF)

OAF is an active data dictionary that is used to:

• Define components for HTML-based applications

• Generate runtime characteristics of applications

• Develop inquiry applications for the HTML-based applications without programming

• Help to support multiple languages

Oracle Workflow provides an infrastructure for communication of data between products, to:

• Manage enterprise business processes

• Support standard and personalized business rules

• Streamline and automate transaction flows

• Manage exceptions without manual intervention

• Deliver notification emails to any Oracle Applications or Internet user


Oracle Alert (ALR)

Oracle Alert allows you to:

• Email notifications to users when an event occurs

• Notify users about specified database exceptions

• Perform routine tasks automatically according to a schedule that you define


Oracle XML Publisher (XDO)

XML Publisher is a Java-based publishing tool that:

• Takes as input XML data from a source such as Oracle Reports, Java, or PL/SQL

• Applies a formatting template created with a desktop application such as Adobe Acrobat or Microsoft Word

• Produces output in PDF or other formats

• Is integrated with the Applications technology stack


Oracle Applications Manager (OAM)

OAM is a key system administration tool:
