Hi,

it in the session when you enable sql_trace. The only problem is that you can enable tracing for a session from a different session, but you can not change statistics_level for a different session. At least I do not know of a way. There are set_int_paramt_in_session and set_bool_param_in_session, but no set_char_param_in_session.

Jonathan mentioned the _rowsource_execution_statistics parameter, this is a boolean parameter and could be set with dbms_system.set_bool_param_in_session.

Btw, from 10g there is a _rowsource_statistics_sampfreq parameter, which could control the performance impact (and accuracy) of gathering rowsource statistics. I haven't done any tests with it though...

Tanel.
