Good to know the new features in R12.2.
I think in Point #3 the default DB for R12.1.1 is and not 11.2.


Atul Kumar says September 22, 2011

Thanks Sridhar Reddy.

Farhan says October 3, 2011

Hi Atul,

Any idea when is 12.2 getting released, as Oracle has nowhere mentioned official release date.

Many of Oracle Customers are deliberately waiting for this release.

Is there a way to get a pre-release trial for EBS 12.2 ?
How are you managing to point out the difference ?

Best Regards,

Has Oracle certified the OIM User Management Connector with EBS 12.2?

Atul Kumar says November 21, 2013

@ chewbaluba ,
I can’t see certification matrix update on Master Note for OIM Oracle E-Business User Management Connector (Doc ID 1291131.1)

However open a SR with SUpport and ask this question, I am sure OIM UM connector for EBS will work with 12.2 version too however for certification check Oracle Support

Roy says September 24, 2014

Hi Atul,

Could you pleae clarify my following custom deployment doubts?
As per note id: 1577661.1, the custom form deployment needs a cutover , which is practically notmpossible in an environment where constance form customizatiin and new forms are adding as per business req. So in this case if both edition are are synchronized, then can compile the form into both fs1 and fs2 , provided we will place all reqd .pll .fmb etc in both file systems instead of a adop cycle.
