Oracle connection suddenly refused on windows 8

Question

I am having all kinds of connection issues with sql developer all of a sudden. It was working till yesterday and stopped working on windows 8 machine.

I am still able to connect via command prompt.
I exclusively opened the port 1521 thats been configured for listener.
Also opened all ports for local programs.
Added TNS_ADMIN to register keys.
But still no luck

Heres my listener.ora:

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
(GLOBAL_DBNAME=orcl)
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\app\rani\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\app\rani\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
  )

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

ADR_BASE_LISTENER = C:\app\rani

• tnsnames.ora content:

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

Everything fine from command prompt:

    Show parameter service_name;

    NAME                                 TYPE        VALUE

I think I have done everything I possibly can, but I'm still not able to conenct my sqlplus developer. I keep getting: Network adapter could not establish connection.

sqlnet log details:

Any help, I am thinking the sql developer is not ready for windows 8 may be

Answer 1

Solved! The issue was LOCAL_LISTENER was not set to orcl. So

SQL> alter system register;

SQL> alter system set LOCAL_LISTENER='(ADDRESS = (PROTOCOL=TCP)(HOST=localhost)(PORT=1521))' scope=both;

did the trick!

Answer 2

I think you should have a service called 'orcl' when you do a

lsnrctl status

But at the moment you don't. Or inversely try to change your tnsname.ora (SERVICE_NAME = orcl) to 'CLRExtProc'.
