oracle-11g-R2監聽文件配置

客戶端連接oracle數據庫時出現如下錯誤：

Listener refused the connection with the following error:
ORA-12514, TNS:listener does not currently know of service requested in connect descriptor

首先看看Oracle服務是否開啟：

然后找到listener.ora監聽文件，具體位置：D:\app\Administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora

即：$ORACLE_HOME/network/admin

原監聽文件lisener.ora配置如下：

# 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 = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = WIN-VATV98IF527)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = D:\app\Administrator

修改為

紅色部分為添加內容，藍色可修改為服務器的IP地址

注意：空格也要嚴格按照要求，否則會報語法錯誤

# 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")
    )

  (SID_DESC =
      (GLOBAL_DBNAME = ORCL)
      (ORACLE_HOME = D:\app\Administrator\product\11.2.0\dbhome_1)
      (SID_NAME = ORCL) )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = WIN-VATV98IF527)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = D:\app\Administrator
