What’s new in Oracle Apps R12

Key points to Note:
  1. Oracle Applications Release 12 is the latest release in the chain of E-Business Suite Releases by Oracle.
  2. This release came up with the new file system model
  3. Autoconfig will not write anything in APPL_TOP, COMMON_TOP area in R12.
  4. All instance specific configurations, log files are written in INST_TOP area. This home provides the ability to share Applications and technology stack.

R12 new features
  1. Applications Server 9i is replaced by 10g (10.1.3.X)
  2. Forms & Reports Version 6i (8.0.6) are replaced by Forms & Reports Version 10g i.e. 10.1.2.X
  3. mod_jserv is replaced by oc4j
  4. Java/ JDK version 1.3.X or 1.4.X will be replaced by JDK 1.5.X
Techstack Components Changes
  • Database (RDBMS_ORACLE_HOME) - 10.2.0.2
  • FORMS ORACLE_HOME (8.0.6 ORACLE HOME equivalence) - 10.1.2
  • OC4J_ORACLE_HOME (iAS ORACLE_HOME equivalence) - 10.1.3
File system level changes
  • A new top INSTANCE_TOP is introduced in Release 12 for configuration and log files along with the other TOP's in existing in 11i.
  • All instance specific configurations, log files are written in INST_TOP area. 
  • This home provides the ability to share Applications and technology stack.
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 easier 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.
