Subject: Using a trigger to turn on tracing
I am trying to use a trigger to turn on tracing for a specified user.
I copied the example from Cary Millsap 's _Optimizing Oracle Performance_.
The text of the trigger is:
create or replace trigger trace_user after logon on database
begin
if user = 'TEST ' then
execute immediate 'alter session set timed_statistics =
true ';
execute immediate 'alter session set max_dump_file_size =
unlimited ';
execute immediate
'alter session set events ' '10046 trace name
context forever, level 8 ' ' ';
end if;
end;
/
When I try to log on as user TEST, I get:
ORA-00604 (See ORA-00604.ora-code.com): error occurred at recursive SQL level 1
ORA-01031 (See ORA-01031.ora-code.com): insufficient privileges
ORA-06512 (See ORA-06512.ora-code.com): at line 5
What privilege does TEST need here?
Thanks,
Peter Schauss
