The only problem is that execute of DBMS_MONITOR is not granted by default to PUBLIC (contrary to DBMS_SESSION). So, for ordinary developer dbms_session.session_trace_enable is the winner. As for SQL_TRACE, I think that it's deprecated because you need to have 'alter session' privilege (which might be a bit dangerous) for using it. So it might be better to just revoke 'alter session', grant execute on dbms_session to public and document sql_trace as deprecated. :) -- Egor http://www.oracledba.ru -- //www.freelists.org/webpage/oracle-l
