Even when Tom Kyte will killme for saying it. Why don't you try to create the trigger under sys

This is the processo I use to get all the statistics, and it always works, at least for me.

#TIMED_STATISTICS     = TRUE
#STATISTICS_LEVEL     = ALL
#max_dump_file_size    = UNLIMITED
*****************************

Restart database

create trigger

CREATE OR REPLACE TRIGGER SYS.TGR_ENABLE_TRACE AFTER
LOGON
ON DATABASE
BEGIN
IF USER = 'SUP' THEN
EXECUTE IMMEDIATE 'ALTER SESSION SET EVENTS ''10046 TRACE NAME CONTEXT FOREVER, LEVEL 12''';
END IF;
END;
/

Do what causes the problem.

to get the xxx server ID, of current user SELECT A.SPID
FROM V$PROCESS A,V$SESSION B
WHERE A.ADDR = B.paddr

AND B.AUDSID = USERENV( 'sessionid' );

search in the trace directory sSID_ora_xxx.trc, that user

Execute
TKPROF \sbbv_ora_740.trc C:\revisar.TXT
check C:\revisar.TXT

The owner of the trigger is system.

Grant it to the trigger owner

I granted alter session to my test user and I still get the same error message.

Any other ideas?

Thanks,

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
