Hi, I need to enable the trace on particular module of the application and using the following command but don't see any trace files generated: EXEC DBMS_MONITOR.serv_mod_act_trace_enable(service_name=>'test', module_name=>'test.exe',waits=>TRUE, binds=>FALSE); (service_name,module_name values are in v$session) If I use Alter system or alter session then it works fine but I need to use for particular module. I don't get any error when ran the above command, do I need to set up something more to get trace files? Thanks --Harvinder -- //www.freelists.org/webpage/oracle-l
