Re: How to trace a Windows session

William,

Recent past I had the same issue. I tried to trace another session, using dbms_system.set_ev or set_sql_trace_in_session. I was able to se the trace successfully, but, there was no trace file generating. When I use, oradebug, it works.

What I did was, first find out the processid of the session which I want to trace,

SELECT spid FROM v$session s,v$process p  WHERE v.paddr=p.addr
 AND s.sid = &SID

Once you get the processid, set the oradebug

oradebug setospid VALUE (which you got from the above query)

Finally, enable the trace:

oradebug event 10046 trace name context forever, level 12 (any level which you want)

Once done, turn off the trace

oradebug event 10046 trace name context off;
