I'm trying to connect remotely to Oracle 12c database with SQL Developer. In order to connect remotely from another computer, on the server running Oracle I opened a port in the Windows 7 Firewall. The listener.ora file, as you see below, has its default listener set to localhost. So, I created second listener called REMOTE_LISTENER, to listen on a different port than 1521. I set it instead to 1531. That part worked, but now the listener isn't letting me in due to this error ORA-12514 Listener does not currently know of service requested in connect descriptor.
Following are the setting from SQL Developer on the remote computer:
On the server side, this is listener.ora file:
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)
)
)
This is the tnsnames.ora file:
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)
)
)
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. You'll notice I also set the port to 1531 to match the listener in listeners.ora file. I still can't connect with SQL Developer on the client side. I am able to connect locally with SQL Developer on the server, but I need to access the database from a different computer. I am able to connect to the database via SQL Plus on the server.
I ran lsnrctl service from the command prompt. Following is the output from that command:
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521))(SERVICE_NAM
E=editor))

The command completed successfully
As you can see, it does show a service instance named "editor". Problem is, it doesn't say what port. You'll also notice a service named "editorXDB". Where that came from, I don't know. That certainly is not in the tnsnames.ora file, and every time I run the lsnrctl services command the port number changes. Anyway, that part, I think, is a red herring. I've been spinning my wheels on this one for several days now. If someone can help me with the necessary steps to ensure connection from a remote computer via SQL Developer, it would be greatly appreciated.
