You need to figure out the scope of what you are doing. Since you want to trace the session of the particular username, you should trace that particular session, not the entire system. As a newbie, you probably don't want to messing around with the spfile until you understand exactly what you are doing.

What exactly do you intend to accomplish by doing this?

You should get into the concepts manual in the docs to understand a few more basic things. What is a database in ODBC-speak is a different concept than in Oracle. You are not in Borland anymore.
