What events are set in the system

Is there a way to find out what events are set in the system?

I have seen and tried this

declare
event_level number;
begin
for i in 100..10999 loop
sys.dbms_system.read_ev(i,event_level);
if (event_level > 0) then
dbms_output.put_line('Event '||to_char(i)||' set at level '||
to_char(event_level));
end if;
end loop;
end;
/

But I know there is an event 472 set via alter system but it is not showing that?

Thanks in advance

Did you try:

SHOW PARAMETER EVENT?

:rolleyes:

that only works for system level events, not sessions level ones (or the other way round, can't remember)

The following should provide all the current system events set:

Code:

---

SQL> oradebug setmypid
SQL> oradebug dump events 4
SQL> oradebug tracefile_name <file_name>

---

If you want just session events you could use 1 above instead of 4.

Thanks very much to all that replied
