After 17327041 to enable COST

Hi,on 11.2.0.3
according to 1453883.1  we applied patch 17327041

As a test we did (from a remote client )
SQL> alter system register;

System altered.

And we expected :

TNS-01194: The listener command did not arrive in a secure transport
But in listener.log we do not have such a message.
Here is my listener.ora

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = WIN-1TVCB2GR06S)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = C:\app

SECURE_REGISTER_LISTENER_LISTENER = (TCP)



Thank you.
