I figured it out.
At first, I had the same disappointing results with the new
v$session.sql_trace column in 10.2.0.2 on AIX - as you can see below:
SQL> execute
dbms_monitor.session_trace_enable(726,147,true,true);
PL/SQL procedure successfully completed.
SQL> select distinct sql_trace, sql_trace_waits, sql_trace_binds
from v$session;
SQL_TRAC SQL_T SQL_T
-------- ----- -----
DISABLED FALSE FALSE
However, after I generated some activity in the traced session, then the
ENABLED trace information appeared in v$session:
<In traced session, sid=726>
SQL> select count(*) from t;
COUNT(*)
----------
9
<Back in sys session>
SQL> select sid, serial#, sql_trace, sql_trace_waits, sql_trace_binds
from v$session where sql_trace = 'ENABLED';
SID SERIAL# SQL_TRAC SQL_T SQL_T
---------- ---------- -------- ----- -----
726 147 ENABLED TRUE TRUE
Also, according to this article
(http://www.oracle.com/technology/pub/articles/10gdba/nanda_10gr2dba_par
t3.html#check), the v$session.sql_trace columns are only populated by
the dbms_monitor.session_trace_enable procedure - not by sql_trace=true,
or event 10046.
