Difference between R12.1 and R12.2 integration with Oracle Access Manager

With the revamp of technology stack in R12.2 of Oracle E-Business Suite (EBS) , the way we integrate Oracle Access Manager (OAM) has changed. R12.2 now is built on Weblogic techstack, which drastically changed how it integrates with Other Fusion Middleware Products like OAM Here is a overview of Steps to configure OAM with EBS R12.1

• Install Oracle HTTP Server ( OHS) 11g
• Deploy & Configure Webgate on OHS 11g
• Install Weblogic
• Deploy & Configure Accessgate on Weblogic
• Integrate Webgate, Accessgate with EBS and OAM/OID

R12.2 has both OHS and Weblogic built-in. So we no longer have to Install OHS and Weblogic for Webgate and Accessgate. All we have to do is Deploy and Configure Webgate and Accessgate. Webgate is deployed on top of R12.2 OHS 11g home. Accessgate is deployed as a separate managed server ( oaea_server1 ) on top of R12.2 weblogic. Here is the pictorial version of the same

R12.1 and 11i EBS integration with OAM/OID

R12.2 Integration with OAM/OID

Basically R12.2 reduces the number of moving parts in the OAM integration EBS. It saves DBAs lot of time, as it reduces the number of servers to manage.
