INST_TOP in R12

INST TOP directory:

(applmgr) - ls
 

 admin/ appl/ certs/ logs/ ora/ out/ pids/ portal/ rgf/
 

(applmgr) -

The Whys and wherefores:

You may get a question why is the change??

There is a need to separate

Code
Data
Config

To ease maintenance of the system. To avoid NFS/MUTEX related issues. Above issue will get resolved if the configuration/lcck files are stored in local system. Another advantage is to gain performance accessing local file system is better than NFS file system.

This directory $INST_TOP got introduced newly in R12. Instance top contains all the config files, log files, ssl certificates, document root etc. Addition of this directory makes the middle-tier more organised, since data is kept separate from config/log files. Another advantage is that, multiple instances can easily share the same middle tier. To create a new instance that shares an existing middle-tier, just create a new instance_top with proper config files and NFS mount the middle tier in the server.
