How to identify a session "Urgent"

[DoubleH]

Hai,
I have to identify the session in which the application has logged on to the database. The problem is that client is JDBC client and so, i am not able to find out the key. For eg. if 100 application users have logged on, then how can i find out the session in which a particular application user can log in. I want the key parameters using which I can find out the session id of a particular user. So that while doing destructive testing i can terminate that particular session.
Thanks & Regards,

Hai,
Thanks. But when the application has logged in as JDBC Client, I am not able to identify the particular session because there are thousands of users wo are accessing the application and all the properties are same except for the session id. Even the OSUser Name, machine , terminal etc are the same because all the users are logged in through the application. Is there any answer for this?
Thanks & Regards,
