My dbms output is not displayed

Question

I’m testing a simple exit from DBMS in Sqldeveloper. I created the connection, ran the set serveroutput on to enable the exits DBMS, but when I run my anonymous code pad, on Saída do Script he presents the message

PL/SQL procedure successfully completed.

But in the window Saída Dbms, Even with my connection already added, nothing is displayed. This is the code I’m trying to execute:

BEGIN
    DBMS_OUTPUT.ENABLE(2000);
    DBMS_OUTPUT.PUT_LINE('Curso Oracle PL/SQL');
END;

Answer 1

First run only this line:

set serveroutput on

Then delete and program normally.
