How to Enable Trace service name and module, another session in oracle

How to Enable Trace servicename and module, another session:

Note:

Test case 1 and Test case 2 : Enable /Disable tracing of sessions on combination of Service name and Module name

Test 3:   Enable/Disable trace on a particular user based on SID,SERIAL# .

Test case 1:

======================

Session 1:

----------------

sqlplus USERNAME/USERNAME@scanname.example.com:1521/DBNAME1

BEGIN

  DBMS_APPLICATION_INFO.set_module(module_name => 'MODULE_NAME',action_name => NULL); 

END;

/

session 2:

----------------

alter session set nls_date_format = 'DD-MON-YYYY HH24:MI:SS' ;

select sysdate from dual;

EXECUTE DBMS_MONITOR.SERV_MOD_ACT_TRACE_ENABLE(service_name=> 'DBNAME1',  module_name=>'MODULE_NAME',  action_name=>DBMS_MONITOR.ALL_ACTIONS,waits=>TRUE, binds=>TRUE ,plan_stat=>'ALL_EXECUTIONS');

Session 1:

----------------

create table test1 (a number, b number);

insert into test1 values (4,5);

insert into test1 values (4,5);

commit;

session 2:

----------------

sqlplus sys as sysdba

alter session set nls_date_format = 'DD-MON-YYYY HH24:MI:SS' ;

select sysdate from dual;

EXECUTE DBMS_MONITOR.SERV_MOD_ACT_TRACE_DISABLE(service_name=>'DBNAME1', module_name=>'MODULE_NAME');

 

 

Session 1:

----------------

exit;
