If it still didn't happen to you, it will. It happened to me more or less five years ago. Being a DBA for quite some time and feeling very comfortable, I was told it was time to begin learning the Application Server. A whole new world was about to unfold and the long forgotten, uncomfortable sensation of being a newbie was back.

It was a long, painful process made even worst with the realization that application servers are way more complicated than databases.

The goal of this series of articles is to help DBA's having a basic understanding of Oracle's Application Server.
