How to stop the generation of the trace files relate to the particular user

Question

Dear All,
Please advice:
Is it possible to stop the trace file created by a user for a particular job (sql/exp)
For example :
Trace files create whenever the user run the sql/exp command from his application server.
This will created a huge files and caused the file system getting full (not in bdump but it is generation in application user home directory).
Is there any method to stop the generation of the trace files relate to the particular user base on that job.
thanks,
Shanoj

Dear SHANOJ
This trigger will created for that specific user by dba or person who have sysdba privs. it will triggered at the login time of that user and alter the sqltrace.
for example we have write one trigger in our database for every ddl operation in database.
CREATE OR REPLACE TRIGGER "SYS"."SYS$DDLTRIG" after DDL on database
declare
v_machinename VARCHAR2(100);
v_osuser VARCHAR2(100);
v_dbuser VARCHAR2(100);
v_host VARCHAR2(100);
v_program VARCHAR2(100);
v_instance VARCHAR2(100);
v_date VARCHAR2(100);
begin
select to_char(sysdate, 'mm-dd-yyyy HH24:MI:SS'),user,sys_context('userenv','OS_
USER'),sys_context('userenv','HOST'), (select instance_name from v$instance),(se
lect program from v$session where sid = (select distinct sid from v$mystat)),(se
lect machine from v$session where sid = (select distinct sid from v$mystat)) int
o v_date,v_dbuser,v_osuser,v_host,v_instance,v_program,v_machinename from dual;
IF ora_sysevent = 'DROP' or ora_sysevent = 'REVOKE' or ora_sysevent = 'GRANT' or
ora_sysevent = 'CREATE' or ora_sysevent = 'TRUNCATE' or ora_sysevent = 'ALTER'
Then
insert into ddl_log_new(v_date,v_dbuser,v_osuser,v_host,v_instance,v_program,v_m
achinename,V_EVENT,V_OBJECT_NAME,V_OBJECT_TYPE,V_OBJECT_OWNER) values (v_date,v_
dbuser,v_osuser,v_host,v_instance,v_program,v_machinename,ora_sysevent,ora_dict_
obj_name,ora_dict_obj_type,ora_dict_obj_owner);
END IF;
END;
i hope above example will helpful for u,
Regards
