2. The product files and directories (for all products ie GL, AP,AR…..).
3. The main applications environment file, called .env on UNIX, and .cmdon Windows.

Concurrent manager Log and view output files are located under $APPLCSF_TOP/log or out

Custom Application

Custom Application should go under CUSTOM_TOP

Oracle Schema Structure


APPS Schema

The APPS schema has access to the complete Oracle E-Business Suite data model. It is analogous to the SYSTEM schema, which has access to the entire database.

The following objects are installed in the APPS schema:
• Packages
• Procedures
• Functions
• Triggers
• Views
• Materialized views

The following objects are installed in the base product schemas:
• Tables
• Sequences
• Indexes
• Constraints
In addition, there are grants from the tables and sequences to the APPS schema, as well as synonyms from the APPS schema to those objects.



Custom Schema
All data objects for custom applications should reside in the custom schema for that application,this includes all custom tables, indexes, sequences and also need public synonym and should grant access to APPS schema.
