orcale 11g r2 : Listener refused the connection with the following error:ORA-12514, TNS:listener doe

首先找一下D:\app\Administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN

看看下面两个文件：

listener.ora和tnsnames.ora

 

listener.ora文件内容如下：

# listener.ora Network Configuration File: D:\app\Administrator\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

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

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.10.188)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = WIN-O1U7CRC9EPV)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

ADR_BASE_LISTENER = D:\app\Administrator

 

 

 

tnsnames.ora文件内容如下：

# tnsnames.ora Network Configuration File: D:\app\Administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN\tnsnames.ora
# Generated by Oracle configuration tools.

TS =
  (DESCRIPTION =
    (ADDRESS_LIST =
     
    (ADDRESS = (PROTOCOL = TCP)(HOST = WIN-O1U7CRC9EPV)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.10.188)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = ts.lh.org)
    )
  )

WCMS =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = WIN-O1U7CRC9EPV)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = wcms.lh.org)
    )
  )

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

 

如果上面的配置文件的路径都没有问题那么重新启动监听服务。
