Oracle Apps R12.2.x File System

Oracle E-Business Suite R12.2.x File System:  Below are the list of changes in Oracle Apps R12.2.x file system

Oracle Apps R12.2.x has dual file system, which helps organisations to have less downtime during patching.  By introducing duplicate file system, Oracle has reduced patching downtime and improved availability of the system.

We can focus on three major parts of the E-Business Suite 12.2.x file system:

  • File System 1:  /u01/R122_EBS/fs1
  • File System 2:  /u01/R122_EBS/fs2
  • Non-Editioned File System:  /u01/R122_EBS/fs_ne

Below are the list of major top level directories from one file system (fs1), its same on secondary file system (fs2):

  • APPL_TOP=/u01/R122_EBS/fs1/EBSapps/appl

Same as Previous release

  • COMMON_TOP=/u01/R122_EBS/fs1/EBSapps/commn

Same as Previous release except OA_HTML, which is pointing to FMW_HOME now.

  • ORACLE_HOME=/u01/R122_EBS/fs1/EBSapps/10.1.2

 The EBSapps directory is another key high-level directory in Oracle E-Business Suite Release 12.2. Typically, it will be located in a path such as /u01/R122_EBS/fs1, at the same level as the inst directory, which contains 10.1.2, appl, and commn directories.

  • INST_TOP=/u01/R122_EBS/fs1/inst

The HTTP and Oracle WebLogic Server configuration files are not stored under the $INST_TOP

  • FMW_HOME=/u01/R122_EBS/fs1/FMW

FMW_HOME is typically will be located in a path such as /u01/R122_EBS/fs1.  It contains user_products (EBS Domain), wlserver_10.3 (weblogic binaries), oracle_common (JRF Files), webtier (HTTP Server) and Oracle_EBS-app1 (JSP files where OA_HTML points to)

  • fs_ne=/u01/R122_EBS/fs_ne

fs_ne contains Concurrent Processing Server log/out files, patches, and other logfiles, which will be accessed by all the nodes in a multi-node enviornment and that’s why it has to be shared across the nodes by keeping it on SAN or NAS file system.
