WHAT IS INSTANCE TOP

·         Instance home is the top-level directory for an Applications Instance which is known as Instance Home and is denoted the environment variable $INST_TOP. This contains all the config files, log files, SSL certificates etc.

Advantages of new INSTANCE HOME 

·         The additional Instance Home makes the middle tier more easy to manage and organized since the data is kept separate from the config files.

·         The Instance Home also has the ability to share the Applications and Technology stack code across multiple instances.

·         Another advantage of the Instance Home is that the Autoconfig writes only in INST_TOP so APPL_TOP and ORACLE_HOME can also be made read only file system if required.
