File System Structure

An Oracle E-Business Suite Release 12.2 system utilizes components from many Oracle products. These

product files are stored below a number of key top-level directories on the database and application

server machines.

Oracle E-Business Suite Release 12.2 uses a dual file system, one file system designated “run edition”,

while the other designated “patch edition”. These two file systems are often referred to as fs1 and fs2.

There is also one more file system which is called non-editioned file system (fs_ne). This file system is

used to store files containing data that is needed across all file systems.

File System1 (FS1)

• Stores a complete copy of all applications and Middle Tier code

File System2 (FS2)

• Stores a complete copy of all applications and Middle Tier code

File System NON Editioned (FS_NE)

• Stores data that is written or read from the file system

• Report Outputs

• Log Files etc
