RE: Database tracing

Then use dbms_support to start traces on all of them:

Put the following into a file called trace.sql:

set verify off
declare
  cursor c1 is select sid, serial# from v$session where osuser = '&1'; begin
  dbms_output.put_line('Staring trace for the following sessions:');   for c1_rec in c1
  loop
    dbms_output.put_line('SID='||c1_rec.sid||', Serial#='||c1_rec.serial#);     \
dbms_support.start_trace_in_session(c1_rec.sid,c1_rec.serial#,waits=>false,binds=>true);   end loop;
end;
/

Then login and run @trace

As I mentioned, when mulitple sessions (connection pools) are already opened by application servers, it is impossible to know from which session a sql is coming through.
