Log 'alter system ' commands

Question

Hi
I am looking for a way to track alter system / alter database commands.
Database triggers are not logging them : I do have a database trigger for DDLs tracking that works great but alter system commands are not captured by it . also trigger 'alter alter on database ' - do not log alter system or alter database
Is there a way for me to force a command to appear in the alert log ?
Or any other way you can think of ?
thanks
Orna

Orna,
YOu can create a database level trigger to capture ALTER statement and insert them into a user defined table. This is just one example you can define trigger at schema level as well.
CREATE OR REPLACE TRIGGER usiuser.myaltertrg
   BEFORE ALTER
   ON DATABASE
DECLARE
   tmpvar   NUMBER;
BEGIN
   tmpvar   := 0;
-- your code to insert alter statement in user defined table.
EXCEPTION
   WHEN OTHERS
   THEN
      -- Consider logging the error and then re-raise
      RAISE;
END myaltertrg;Regards
