A
Journey from Oracle E-Business Suite R12.1 to R12.2
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
There are lots of updates coming in
this release, but from a technology stack perspective, EBS 12.2 will be notable
for two things:
- Replacing Oracle Containers for Java (OC4J) 10g with
WebLogic Server 11g
- Online Patching support via 11gR2 Edition-Based
Redefinition
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
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 below
things:
- 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
Oracle E-Business Suite R12 (12.2) uses Oracle
Fusion Middleware 11g R1 PS3 (11.1.1.4) including WebLogic 10.3.4 as
its application server (Note: In previous version of R12 i.e. 12.0.X and
12.1.X this is 10g R3 i.e. 10.1.3.X). Oracle HTTP server in R12 (12.2) is
11.1.1.4
- 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.
“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.”
It is not released yet
but It will include significant changes to the Application Server architecture and It will change Patching, Cloning & the User Experience.

Oracle E-Business Suite R12 (12.2) uses Oracle
Application Server 10g R3 (10.1.2.3) for Forms & Reports (Note: In previous version of R12 i.e. 12.0.X and 12.1.X,
forms are reports are of same version i.e. 10.1.2.3)
·

(12.2) is 11g R2 (11.2.X) . (Note: In previous version
of R12 i.e. 12.0.X, default database is 11.1 and 12.1.X, default database is
11.2)

Oracle JSP Compiler (OJSP) 10.1.3.5 (12.0.X and
12.1.X) is replaced by WebLogic JSP Compiler 11.1.1.4 in R12 version 12.2
·
Oracle Apps R12.2 cloning will also support
Fusion Middleware (11.1.1.4 – discussed in point 1) cloning.
