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 =3D 'TEST' then
	 	execute immediate 'alter session set timed_statistics =3D
true';
		execute immediate 'alter session set max_dump_file_size =3D
unlimited';
		execute immediate=20
				'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: error occurred at recursive SQL level 1
ORA-01031: insufficient privileges
ORA-06512: at line 5

What privilege does TEST need here?

Thanks,
Peter Schauss
