Oracle Apps 11i - File SystemAn Oracle Applications Release 11i system utilizescomponents from many Oracle products. Theseproduct files are stored below a number of key top-level directories on the database and applicationserver machines. Depending on how you chose toinstall Applications, these product directories maybe located on a single machine (the simplest case)or on multiple machines (the most common type ofdeployment). Operating system environmentsettings indicate the location of the various files inthe file systems of the database and applicationserver machines.This topic discusses the association between theseenvironment settings and the corresponding filesand directories.Note: is the name of your system determinedthrough Rapid Install at the time of installation. Forexample, PROD.
•The DATA or DATA_TOP directory is located on the database server machine, and contains the system tablespaces, redo log files, data tablespaces, index tablespaces, and database files. •The DB directory is located on the database server machine, and contains the ORACLE_HOME for the Oracle9i database. •The APPL or APPL_TOP directory contains the product directories and files for Oracle Applications. •The ORA directory contains the ORACLE_HOMEs for the Applications technology stack components. •The COMN or COMN_TOP (or COMMON_TOP) directory contains directories and files used across products.Figure 2. Applications Directory Structure
The DATA DirectoryThe DATA file system contains the data (.dbf) filesof the Oracle database. Rapid Install installs thesystem, data, and index files in directories belowseveral mount points on the database server. Youcan specify the directory names of the mountpoints on the database server during installation.DB and ORA DirectoriesOracle Applications supports employing anApplications database of one version, while linkingApplications programs using the tools from asecond or third version of the database. Thismultiple ORACLE_HOMEs configuration allows newfeatures of the database to be supported, whilemaintaining compatibility with earlier releases.Release 11i utilizes three ORACLE_HOMEs:1. The 9.2.0 ORACLE_HOME (Applications databasehome) is located in the DB directory. It containsthe files needed for running and maintaining theOracle Applications database.2. The 8.0.6 directory contains the ORACLE_HOMEfor the Developer 6i products (Forms, Reports, andGraphics). The product libraries in the 8.0.6ORACLE_HOME are used to relink OracleApplications executables.3. The iAS directory, also under the ORA, containsthe ORACLE_HOME for Oracle9i Application Server.
The APPL DirectoryOracle Applications files are stored in the APPLdirectory, which is known as the APPL_TOPdirectory.The APPL_TOP directory contains:1. The core technology files and directories.2. The product files and directories (for allproducts).3. The main applications environment file, called.env on UNIX, and .cmdon Windows.4. The consolidated environment file, calledAPPS.env on UNIX, and APPS.cmd on Windows.
