SERVEROUTPUT이 활성화되었는지 단순히 확인해야 할 수도 있습니다. 예 :

SQL> begin 
    2 dbms_output.put_line('something'); 
    3 end; 
    4/

PL/SQL procedure successfully completed. 

SQL> set serveroutput on 
SQL> begin 
    2 dbms_output.put_line('something'); 
    3 end; 
    4/
something 

PL/SQL procedure successfully completed.
