title: How to create a dummy Oracle Server to connect with Toad
body: <p>I am interested in creating a module which accepts TCP connections and handles OCI calls made from db tools like Toad, or PL/SQL Developer.</p>
  
  <p>My aim is to manipulate data before sending it to client, hide some stuff etc. Is it possible to do something like that ?</p>
  
  <p>More specifically, we created a data migration tool coded in java. If i can get calls from a db tool and call the tool's methods using JNI, i  achive what i am intended to do. As far as i know there is no api to create a OCI server to connect.</p>
