dbms_application_info through connection pooling - Info about sessions

Hello all, 

As I could not find a related Community for Administration of Siebel I post it here although my question has nothing to do with the Installation. Excuse me for that. 

I try to find a way to use dbms_application_info with Siebel in order to provide me the username and the client IP of the sessions connected through connection pooling.

Have you ever been experienced in that for a Siebel environment? This would enhance our DBA monitoring as it helps us to identify the session rapidly.

Thank you in advance
