The PL/SQL SET SERVEROUTPUT ON command is used in Oracle SQL*Plus (or other similar Oracle interfaces) to enable the display of output from PL/SQL blocks. When you use commands like DBMS_OUTPUT.PUT_LINE() in your PL/SQL code to print values, you must use SET SERVEROUTPUT ON to make sure that the output is shown in the console. This command helps to debug and track the flow of your PL/SQL programs by displaying output results directly to the user interface.
