Oracle 9i and user activity logging

Question

Hi,
i am new on the matter but i have to trace the user activity and build a small application.
those are the specifications :
i'm using oracle 9i database version on 64 bit
the O.S. used is Unix Aix 5.2
for each data base we using i have to trace the user activity all of them, about 3 DB + application
i have create some some triggers to get some information, but still the work is there :
create trigger ... after logoff on database .. begin insert into table xx_tab ( ,,,,) end ;
create trigger ... after ddl on database .. begin insert into table xx_tab ( ,,,,) end ;
create trigger ... after logon on database .. begin insert into table xx_tab ( ,,,,) end ;
create trigger ... after servererror on schema .. begin insert into table xx_tab ( ,,,,) end ;
Here is the issue i am faced to /
how could we simulate a create trigger ... after DML on database or schema ? as far as i know we trigger a DML only on a specific table. Is there any possibility to trigger a DML on any database object or schema?
for the moment i don't know if it 's the good think to do but, but it's a try, if you have any idea or other methods to trace the user activities on DB, please don't hesitate to get me informed.
Rgds,
Paul
