Starting November 19th, Oracle Community will require Multi-Factor Authentication (MFA) for all member logins. This simple extra step helps protect your account—and the community data—by adding an additional layer of security during sign-in.
We have upgrade database from 11.2.0.2 to 11.2.0.3(first). And upgraded oracle applications from 11.5.10.2 to R12.1.3.
In this scenarios do we have to apply interoperatability using note - Interoperability Notes EBS R12 with Database 11gR2 [ID 1058763.1]. After upgrade to R12.1.3 is complete.
