oracle-11g-R2监听文件配置

客户端连接oracle数据库时出现如下错误：

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服务是否开启：

oracle-11g-R2监听文件配置

然后找到listener.ora监听文件，具体位置：D:appAdministratorproduct11.2.0dbhome_1NETWORKADMINlistener.ora

即：$ORACLE_HOME/network/admin

原监听文件lisener.ora配置如下：

# listener.ora Network Configuration File: D:appAdministratorproduct11.2.0dbhome_1
etworkadminlistener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = D:appAdministratorproduct11.2.0dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:appAdministratorproduct11.2.0dbhome_1inoraclr11.dll")
    )
  )

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

ADR_BASE_LISTENER = D:appAdministrator

修改为

红色部分为添加内容，蓝色可修改为服务器的IP地址

注意：空格也要严格按照要求，否则会报语法错误

# listener.ora Network Configuration File: D:appAdministratorproduct11.2.0dbhome_1
etworkadminlistener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = D:appAdministratorproduct11.2.0dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:appAdministratorproduct11.2.0dbhome_1inoraclr11.dll")
    )

   (SID_DESC =
      (GLOBAL_DBNAME = ORCL)
      (ORACLE_HOME = D:appAdministratorproduct11.2.0dbhome_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:appAdministrator
