Information in this document applies to any platform.
This problem can occur on any platform.


Attempting to connect remotely to an instance that is not started using a privileged account.  This might be necessary to start up the database remotely or via the listener.  The following error is returned:

SQL> connect sys/password@ORCL as sysdba
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor

The TNS connect string used is in the following form:

       (ADDRESS_LIST =
          (ADDRESS = (PROTO = TCP)(HOST = myhost)(PORT = 1521))


It is likely the database has been shutdown since the last successful connection via the listener.
