set serveroutput [on|off] is used to enable or disable the output made by the DBMS_OUTPUT package, for example in sql*Plus; in your example, it has no effect. –  Nicolas Durand Oct 22 '13 at 13:09
    
Thank you Nicolas :) Any weblinks which will give more information would be much beneficial. However Now I understood the purpose of set serveroutput. Thanks a lot –  user3475 Oct 22 '13 at 13:39

set serveroutput on executed in SQL Plus executes behind the scenes:

dbms_output.enable(buffer_size => NULL);

set serveroutput off executes:

dbms_output.disable;
