ORACLE HOMES

Oracle Applications uses three Oracle homes:

RDBMS ORACLE_HOME

Used by the Database Server Application Server 10.1.2 ORACLE_HOME

Also known as Tools, C or DeveloperORACLE_HOME

Replaces the 8.0.6 ORACLE_HOME in 11i. Application Server 10.1.3 ORACLE_HOME

Also known as Web or Java ORACLE_HOME

Replaces the iAS ORACLE_HOME in 11i.

ORACLE APPLICATIONS

UTILITIES (AU)

AU is used to maintain an Application system.

AU hosts certain product files in central location

Eg: forms source files (.fmb)

This allows generating on-site classes of files like formsand reports.

Generating forms or reports may require access toshared PL/SQL libraries.

- These are also copied to AU_TOP


26/54

ORACLE APPLICATION

FRAMEWORK (OAF)

OAF is active data dictionary that is used to:

Define components for HTML based applications.

Generate runtime characteristics of applications.

Help to support multiple languages.


27/54

ORACLE WORKFLOW (WF)

Oracle Workflow provides an infrastructure forcommunication 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 mails to Oracle Applications orInternet user.


28/54

ORACLE ALERT (ALR)

Oracle Alert allows you to:

Email users whenever an event occurs.

Notify users about database exceptions.

Perform routine tasks automatically according to a

schedule that is defined.


29/54

ORACLE XML

PUBLISHER (XDO)

XML publisher is a Java-based publishing tool that:

Takes input XML data from a source like Oracle

Reports, Java, or PL/SQL Applies a formatting template created with a desktop

application.

Produces output in PDF or other formats.

Is integrated with the Application technology stack

ORACLE APPLICATIONS

LANGUAGES


47/54

MULTIPLE LANGUAGES

IN THE DATABASE Oracle Applications database uses _TL tables to store

translated information for multiple languages:

For example, FND_APPLICATION_TL storestranslated information

about all the applications registered with the OracleApplication Object Library.

There are also _VL views, which retrieve data in thecorrect language.

These use the _TL tables, in conjunction with theusers session language.


48/54

CHARACTER SETS

Character sets are encoded binary values that represent letters

numerals and punctuation marks, and include the followingexamples:


49/54

CHARACTER SET

DATABASE TIER By default Rapid Install creates a new database with

US7ASCII

character set, a vision instance with the UTF8 character set.

A different character set can be chosen in Rapid install.

Multibyte character sets may require more storage spacethan single

byte character sets.


50/54

CHARACTER SET

APP

LICATION TIER By default Rapid Install creates a new database withUS7ASCII

character set, a vision instance with the UTF8 characterset.

Rapid Install recommends the application tier characterset based on the languages licensed.

Character sets on all tiers must be compatible with eachother, to prevent data loss

All Application Tier servers must have the same set oflanguages installed.


51/54

CHARACTER SET

DESKTOP TIER Language support must be available on the desktop

client.

The desktop browser must support character set and

language specific capabilities. The character set of the browser is set by Oracle

Applications for each session.
