Question

I am getting the following errors while from the lsnrctl status command:

C:\Users\pna105>lsnrctl stat

It was working fine before restart but now it is not working and I also can't access my Oracle homepage.

My tnsnames.ora is:

  ORACLE = 
  (DESCRIPTION =  
    (ADDRESS_LIST =  
      (ADDRESS = (PROTOCOL = TCP)(HOST = Localhost)(PORT = 1521))  
    )  
    (CONNECT_DATA =  
      (SERVICE_NAME = ORACLE)  
    )  
   )

   LISTENER_ORACLE =
  (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))


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

My listener.ora is: (Here were error due to brackets misplaced adding few spaces resolved the problem TNS-12518)

   SID_LIST_LISTENER =
   (SID_LIST =
   (SID_DESC =
    (SID_NAME = ORACLE)
    (ORACLE_HOME = C:\app\PNA105\product\11.2.0\dbhome_1)
  )  
  (SID_DESC =
    (SID_NAME = PLSExtProc)
    (ORACLE_HOME = C:\app\PNA105\product\11.2.0\dbhome_1)
    (PROGRAM = extproc)
   )
   (SID_DESC =
  (SID_NAME = CLRExtProc)
  (ORACLE_HOME = C:\app\PNA105\product\11.2.0\dbhome_1)
  (PROGRAM = extproc)
  (ENVS = "EXTPROC_DLLS=ONLY:C:\app\PNA105\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\PNA105

Following is the output of lsnrctl start command

C:\Users\pna105>lsnrctl start

T he command completed successfully

Answer 1

I had the same problem. Solution in my case: run CMD as ADMINISTRATOR. then type and execute: "lsnrctl start" wait about 2 minutes then should work. (in my case was only 50 seconds, but just to be on the safe side)
