Use of two Oracle Application Server ORACLE_HOMEs in Release 12

In this post I would like to share with you all, the use of two Oracle Application Server ORACLE_HOMEs in Release 12.
Two different Oracle Application Server (OracleAS) 10g releases, in separate ORACLE_HOMEs, are used in Oracle E-Business Suite Release 12. This enables Oracle E-Business Suite to take advantage of the latest Oracle technologies as illustrates in picture, the functional usage of the two Oracle Application Server
ORACLE_HOMEs.

Oracle applications R12 having the features of this architecture include:
• The latest version of Oracle Containers for Java (OC4J), the successor to JServ, is included in Oracle Application Server 10.1.3.
• All major services are started out of the OracleAS 10.1.3 ORACLE_HOME.
• The Oracle E-Business Suite modules (packaged in the file formsapp.ear) are deployed into the OC4J-Forms instance running out of the OracleAS 10.1.3
ORACLE_HOME, while the frmweb executable is invoked out of the OracleAS 10.1.2 ORACLE_HOME.


This picture will show the relationship of the two Application Server ORACLE_HOMEs  and the database ORACLE_HOME.

Advantage of this high-level architecture include:
• The Oracle Application Server 10.1.2 ORACLE_HOME (sometimes referred to as the Tools, C, or Developer ORACLE_HOME) replaces the 8.0.6 ORACLE_HOME provided by Oracle9i Application Server 1.0.2.2.2 in Release 11i.
• The Oracle Application Server 10.1.3 ORACLE_HOME (sometimes referred to as the Web or Java ORACLE_HOME) replaces the 8.1.7-based ORACLE_HOME provided by Oracle9i Application Server 1.0.2.2.2 in Release 11i.
