ora-12505 error while connecting via SQL Developer

I'm trying to connect remotely to Oracle 12c database with SQL Developer. In order to connect remotely from another computer, on the computer running Oracle I opened a port in the Windows 7 Firewall. That part worked, but now the listener isn't letting me in due to this error ORA-12505. It is saying it doesn't recognize the SID I provided when I try to connect with SQL Developer in the remote computer. I even tried setting service name to "editor", but still nothing.

Following are the setting from SQL Developer on the remote computer:

enter image description here

On the server side, this is listener.ora:

SID_LIST_LISTENER =
(SID_LIST =
  (SID_DESC =
    (SID_NAME = CLRExtProc)
    (ORACLE_HOME = C:\app\Owner\product\12.1.0\dbhome_1)
    (PROGRAM = extproc)
    (ENVS = "EXTPROC_DLLS=ONLY:C:\app\Owner\product\12.1.0\dbhome_1\bin\oraclr12.dll")
  )
)

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
      (SERVICE_NAME = editor)
    )
 )

 REMOTE_LISTENER =
   (DESCRIPTION_LIST =
     (DESCRIPTION =
       (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.19)(PORT = 1531))
       (SERVICE_NAME = editor)
     )
   )

And tnsnames.ora:

EDITOR =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.19)(PORT = 1531))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = editor)
    )
  )

  LISTENER_EDITOR =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
      (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = editor)
    )
  )


  ORACLR_CONNECTION_DATA =
    (DESCRIPTION =
      (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
    )
  )

You'll notice that the default listener is set to localhost on port 1521. As long as that stays like that, I can connect on the server with SQL Developer. So in order to connect remotely, I setup a second listener set for port 1531 and entered the IP address of the server. The firewall has also been setup to allow a connection through port 1531. As you can see, I did edit the tnsnames.ora file a bit to allow for a connection to the Editor database, but my edit didn't seem to fix anything. I still can't connect with SQL Developer on the client side. On the server, I tried using the Oracle Net Configuration Assistant to test the Editor entry and wound up with error message:

ORA-12514 Listener does not currently know of service requested in connect descriptor.

UPDATE Sept. 9 2014:

I was asked to run lsnrctl status from the command prompt. Following is the output from that command:

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521))(SERVICE_NAM
E=editor))

OK...so what am I supposed to do with this???

I am using SQL Developer on the remote computer. The image above is the dialog box I'm using to try to connect. I went looking for a file on the remote computer named tnsnames.ora and didn't find any. – Alan Sep 7 at 13:58

You need an Oracle Client on the remote client computer with the same tnsnames.ora file as you have on the server.

Forgive me if I don't understand the question properly. Are there 3 machines involved. Client, listener and database ? If you are just trying to advertise the database on port 1531 then modify the LISTENER section in the listener.ora file to include an additional port

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1531))
(SERVICE_NAME = editor)
)
)

Don't use the SID, use the SERVICE - from what your example shows, 'editor'.

On 12c if you are connecting to a pluggable then you will ALWAYS need to use service. The SID will resolve to the Container Database (CDB).

Ton confirm that is right, run the 'lsnrctl status' command on your server, and check out what the actual services are being listened to by the listener.
