Why my DBMS_OUTPUT utility doesn't work

Question

This is the first time I use DBMS_OUTPUT utility in AIX. I did not get anything printed on my screen. Do I miss anything before I use it? Please help!!

Answer 1

1) This is the wrong forum. You want "General" or something.
2) To use DBMS_OUTPUT, you can use DBMS_OUTPUT.PUT_LINE('Message.');
3) To actually view the output, "SET SERVEROUTPUT ON". (It's OFF by default.)
In case you really don't get it, here's an example:
SET SERVEROUTPUT ON
BEGIN DBMS_OUTPUT.PUT_LINE('Hi.'); END;
The output will be something (rougly) like this:
Server output set to ON.
Hi.
