Monitor DB Transactions

In one of my projects, I need to monitor real time all database transactions in the Oracle dbms server in real time. The transactions are filtered and transported to interested applications by messaging servers. The constraints are real time monitoring, non intrusive monitoring mechanism (avoid triggers and alerts) and remote monitoring. Are there any tools or programs that meet the above requirements? Alternatively, I can implement the program myself but I need some kind souls to give me some pointers. Any references and books would help.

Thanks.
