Don't use dbms_system.set_sql_trace_in_session; use
dbms_support.start_trace_in_session. Big difference. The dbms_support
one lets you catch waits and binds. The dbms_system one doesn't. See
"How to activate extended SQL trace" at
http://www.hotsos.com/e-library/index.html for details.

Using the SAP tools, we can isolate the process that is
running (at least instantaneously) SQL that we're interested
in. I then use...
begin
sys.dbms_system.set_sql_trace_in_session( &sid, &serial, TRUE);
end;
/
...to trace that session. If we could not find it, you're absolutely correct that we'd have to turn tracing on globally, and then walk over 400 trace files looking for SQL of interest. NOT how I want to spend my day!
Cheers,
Mike

When you say 'sql trace' do you mean 10046?
Which session(s) did you trace? =20
As SAP users get their data through an application server, I would suspect you would need to turn tracing on for all SAPR3 connections.
