>>The most substantial difference is the inclusion of weblogic server in place of 10.1.3 Oracle home .
The 10.1.3 Application server is replaced by FMW_HOME.
The major change in R12.2 is involvement of Weblogic server to manager all the forms,oacore servers.
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.
>>In R12.2 we have two filesystems fs1(run filesystem) and fs2(patch filesystem), where as In R12.1.3 we only one application filesystem.
>>In 12.1.3 we have adpatch utility for patching, In R12.2.4 we have adop(online patching) utility patching.
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.
>>A new “EBSenv.env” is introduced to select RUN/PATCH file system.
>>How to change apps user password in R12.2.4
