E-Business Suite 12.2


There are lots of updates coming in this release, but 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
2) Online Patching support via 11gR2 Edition-Based Redefinition

1. Replacing OC4J with WebLogic Server

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.

“To upgrade an application while it is in use, you copy the database objects that comprise the application and redefine the copied objects in isolation. Your changes do not affect users of the application—they continue to run the unchanged application. When you are sure that your changes are correct, you make the upgraded application available to all users.”

Online Patching means that patches that change EBS database objects can be applied while the E-Business Suite production instance is fully operational. Only a short downtime will be required to complete the patching process. This will make your patching downtimes more predictable.
