Based on high influx of mail from users requesting difference between Oracle Applications Release 12 and 11i , I decided to dedicate this post to outline few major technical difference.
Database:
Database Version in 11i (11.5.9 & 11.5.10) was 9i Rel 2 where as in Release 12 its 10g R2 (10.2.0.2)
Application Tier:
Tech Stack in Application Tier consist of iAS(1.0.2.2.2) & Developer 6i (Forms & Reports 8.0.6) but in Applications R12 it is build on Fusion Middleware (10g Web Server and 10g Forms & Reports)
Sub component in Application Tier
A) HTTP Server or Web Server in R12 is Version 10.1.3 which is built on Apache version 1.3.34. In apps 11i it is Version 1.0.2.2.2 built on Apache Version 1.3.19
B) Jserv in apps 11i is replaced by OC4J (mod_jserv is replaced by mod_oc4j)
C) Forms Version 6i in Apps 11i is replaced by Forms 10.1.2.0.2 in R12
D) Reports Version 6i in Apps 11i is replaced by Reports 10.1.2.0.2 in R12
E) JDBC version is changed from version 9 in apps 11i to version 10.2.0 in Apps R12
F) modplsql or mod_pls is removed from Apps R12 (What will happen to my mod plsql applications- coming soon* )
G) Java processes use JDK/JRE version 1.5.0 in R12 against JDK version 1.3.1 or 1.4.2 in Apps 11i
H) For various environment variable changes check below picture
I) New top INSTANCE_TOP added in Release 12 for configuration and log files

Hi,
I am trying to install Oracle Apps12 on RHEL but at the end of installation only one error display which is
“Login Page
checking URL = http://apps.ib.com:8014/OA_HTML/AppsLogin
RW-50016: Error: - {0} was not created:

I am not sure if it requires any patch like 5885627.
It would be great if any one can suggest the solution or provide the link from where I can get this patch As I don’t have access to metalink.

Where is the report server executable in R12. In 11i, we can check the OS server process for reports and forms server with ps -ef|grep rwmts and ps -ef|grep f60srvm. But in R12 how do we check the OS process for forms and reports server?
We replied
==========
Forms are Reports in R12 are in OC4J process which is controlled by OPMN check “opmnctl status” for R12
Atul
Hi Atul,
I checked the opmnctl status in R12, i can see the status for forms,asg,oacore and HTTP_Server in that. But where do i find if the reports server is running for R12.
Thanks,
Karthik
Open adrepctl.sh and look for port on which its listening & log file then “ps -ef | grep report_port_no”

Hi Atual,
Do you any documentation on migrating from 10.7 to R12?
Thanks.
Paul,
You can’t go to R12 from 10.7. First you have to upgrade it to minimum 11.5.7
chiranjeevi,
Check log file for installation and startup of services in R12 to find any issues http://onlineappsdba.com/index.php/2007/12/25/oracle-r1212i-log-file-patch-clone-startupshutdown/
This is because services didn’t start properly either because of failed installation or any other reason which you can find in log files
