In this database, there are 'ST' enqueue locks and i have to identify the SQL
statements issued by blocking and blocked sessions. I cannot use DDL triggers.
Thanks

Joseph,
Would a DDL trigger be an acceptable solution to you? I haven't
tried it recently, but I *think* that you can catch the statement text
in the trigger. I am not fully certain about that, because since DDL
statements are nothing else (ultimately) than DML statements applied to
dictionary tables some are broken into their constituent DML components
so fast that they let no track in the SGA.
Otherwise perhaps that V$object_dependency could help too ...
