Disable EM Express
First of all, we check the current port of Enterprise Manager Express (EM Express) like this:
SQL> select dbms_xdb_config.getHttpsPort() port_number from dual;
As we can see, the port of EM Express is open. To disable EM Express, we set the port value to zero.
For secure http connection
SQL> exec dbms_xdb_config.sethttpsport(0);
For normal http connection
SQL> exec dbms_xdb_config.sethttpport(0);
We turned it off.
