解决oracle数据库“监听程序当前无法识别连接描述符中请求的服务”

 

 

今晚搞了几个小时的oracle配置，现在终于连上了，同时也发现好多人每次重装系统后都得重装oracle，现将我如何处理这一类问题的方法分享如下，嘿嘿，屡试不爽的，更重要的是不用修改ip，直接用本地连接localhost，不论是否联网都可以这样配置！

 

我的oracle安装路径在F盘的app文件夹下，

首先找到F:\app\Administrator\product\11.1.0\db_1\NETWORK\ADMIN下的listener.ora和tnsnames.ora这两个文件，用记事本打开就可以

 

用下面的这些代码替换listener.ora中原有的代码

注：路径要是自己的安装路径

# listener.ora Network Configuration File: F:\app\Administrator\product\11.1.0\db_1\network\admin\listener.ora

# Generated by Oracle configuration tools.

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (SID_NAME = PLSExtProc)

      (ORACLE_HOME = F:\app\Administrator\product\11.1.0\db_1)

      (PROGRAM = extproc)

    )

     (SID_DESC =

      (GLOBAL_DBNAME = orcl)

      (ORACLE_HOME = F:\app\Administrator\product\11.1.0\db_1)

      (SID_NAME = orcl)

    )

 

  )

LISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

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

    )

  )

 

 

 

 

# tnsnames.ora Network Configuration File: F:\app\Administrator\product\11.1.0\db_1\NETWORK\ADMIN\tnsnames.ora

# Generated by Oracle configuration tools.

ORCL =

  (DESCRIPTION =

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

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = orcl)

    )

  )

EXTPROC_CONNECTION_DATA =

  (DESCRIPTION =

    (ADDRESS_LIST =

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))

    )

    (CONNECT_DATA =

      (SID = PLSExtProc)

      (PRESENTATION = RO)

    )

  )

 

 

 用下面的这些代码替换tnsnames.ora 中原有的代码

 

 

# tnsnames.ora Network Configuration File: F:\app\Administrator\product\11.1.0\db_1\NETWORK\ADMIN\tnsnames.ora

# Generated by Oracle configuration tools.

ORCL =

  (DESCRIPTION =

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

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = orcl)

    )

  )

EXTPROC_CONNECTION_DATA =

  (DESCRIPTION =

    (ADDRESS_LIST =

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))

    )

    (CONNECT_DATA =

      (SID = PLSExtProc)

      (PRESENTATION = RO)

    )

  )

替换完成之后重启oracle数据库服务就可以了
