The appl Directory

Oracle E-Business Suite files are stored in the <dbname>APPL directory, which is generally known as the APPL_TOP directory.
Figure 2-5 APPL_TOP Directory Structure

The APPL_TOP directory contains:

• The core technology files and directories.
  
• The product files and directories (for all products).
  
• The main Oracle E-Business Suite environment file, called <CONTEXT_NAME>.env on UNIX, and <CONTEXT_NAME>.cmdon Windows.
  
• The consolidated environment file, called APPS<CONTEXT_NAME>.env on UNIX, and APPS<CONTEXT_NAME>.cmd on Windows.

Note: CONTEXT_NAME is the Oracle Applications context, described further in Chapter 5. Its default value is <SID>_<hostname>.
Rapid Install creates a directory tree for every Oracle E-Business Suite product in this APPL_TOP directory, whether licensed or not.
Warning: Regardless of registration status, all Oracle E-Business Suite products are installed in the database and the file system. Do not attempt to remove files for any unregistered products.
Rapid Install installs a new APPL_TOP directory when you upgrade. Rapid Install does not delete any existing product files from earlier releases, but unloads new product files into a new apps/apps_st/appl directory tree.
Each APPL_TOP directory is associated with a single Oracle E-Business Suite database. If you install both a Vision Demo system and a test system, Rapid Install will lay down two file systems, one for each of these Oracle E-Business Suite systems.
