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:

1. Replacing Oracle Containers for Java (OC4J) 10g with WebLogic Server 11g
2. 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

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)

·         Default Database for Oracle E-Business Suite R12 (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.

·         Oracle Web Applications Desktop Integrator (Web ADI) in R12.2 is now certified with Microsoft Office 32-bit and 64-bit.

JSP error Request URI:/OA_HTML/RF.jsp java.lang.NoClassDefFoundError

After running the autoconfig on test instance , faced this error when logging into e-business suite:

JSP Error:
Request URI:/OA_HTML/RF.jsp
Exception:
java.lang.NoClassDefFoundError

JSP Error:
Request URI:/OA_HTML/AppsLocalLogin.jsp
Exception:
java.lang.NoClassDefFoundError


The jserv.log and OACoreGroup..stderr (where is the number of the JVM) will show errors like:-

Exception in static block of jtf.cache.CacheManager. Stack trace is:
oracle.apps.jtf.base.resources.FrameworkException: IAS Cache initialization failed. The Distributed Caching System failed to initialize on port: 12346. The list of hosts in the distributed caching system is: hostA.domain.com . The port 12346 should be free on each host running the JVMs. The default port 12346 can be overridden using

Solution: Disabling Java Caching mechanism also resolves this issue.

Just commenting out the following line in jserv.properties to disable Java Caching

### wrapper.bin.parameters=-DLONG_RUNNING_JVM=true

FRM-92050 Error with Internet Explorer-8

While using oracle applications R12 with Internet Explrer 8 an Form Server related error is encountered (FRM-92050: Failed to connect to the server).To, avoid this problem Disable the XSS Filter option in IE8.

Tools--> Internet options--> Security-->Security level for this zone --> Custom level-->Disable XSS filter

Now there is no issue with Error FRM-92050
