What’s coming in the next major version of Oracle E-Business Suite 12.2?
I will try to analyze architectural overview of the latest updates, installation and upgrade options, new configuration options, and new tools for hot-cloning and automated “lights out” cloning in R-12.2
Oracle E-Business Suite 12.1 Architecture

Oracle E-Business Suite 12.2 Architecture
Release 12.2 will replace Oracle Containers for Java (OC4J) 10g with WebLogic Server 11g
Release 12.2 Database tier will run RDBMS 11gR2 to support online patching


There will be number of updates coming in release R12.2, from a technology stack perspective, EBS 12.2 will be notable for two things:
1-Replacing Oracle Containers for Java (OC4J) 10g with WebLogic Server 11g
EBS 12.2 will use WebLogic Server from Fusion Middleware 11g in place of OC4J 10g as part of the release’s internal technology stack. Other additional new Fusion Middleware 11g components used will include WebLogic JSP and UIX 11g
2-Online Patching support via 11gR2 Edition-Based Redefinition
EBS 12.2 will use the 11gR2 Database’s Edition-Based Redefinition features to provide support for Online Patching. Edition-Based Redefinition is really exciting new technology. From the 11gR2 Application Developer’s Guide:
“Edition-based redefinition enables you to upgrade the database component of an application while it is in use, thereby minimizing or eliminating down time.

When you are sure that your changes are correct, you make the upgraded application available to all users.”
