# listener.ora Network Configuration File: E:\oracle\product\10.1.0\Db_1\NETWORK\ADMIN\listener.ora

# Generated by Oracle configuration tools.

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (SID_NAME = PLSExtProc)

      (ORACLE_HOME = E:\oracle\product\10.2.0\Db_1)

      (PROGRAM = extproc)

    )

    (SID_DESC =

      (GLOBAL_DBNAME = ORCL)

      (ORACLE_HOME = E:\oracle\product\10.2.0\Db_1)    

      (SID_NAME = ORCL)

    )

  )

LISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))

    )

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = TCP)(HOST = WIN-7OT0VFHL2B5)(PORT = 1521))

    )

  )

 解决办法：     注意上图粗体显示的部分注意路径是否存在

——————

1. 打开文件"<OracleHome>/network/admin/listener.ora" ,你将看到如下的内容:

    SID_LIST_LISTENER =

    (SID_LIST =

      (SID_DESC =

        (SID_NAME = PLSExtProc)

        (ORACLE_HOME = D:\oracle\product\10.2.0\db_1)

        (PROGRAM = extproc)

      )

    )

   2. 将下面的语句添加到上面的语句中去。

        (SID_DESC =

        (GLOBAL_DBNAME = ORACLE)

        (ORACLE_HOME = D:\oracle\product\10.2.0\db_1) 

        (SID_NAME = ORACLE)

       )

   3. 文件的内容则变成了如下所示:

     SID_LIST_LISTENER =

    (SID_LIST =

      (SID_DESC =

        (SID_NAME = PLSExtProc)

        (ORACLE_HOME = D:\oracle\product\10.2.0\db_1)

        (PROGRAM = extproc)

      )

      (SID_DESC =

        (GLOBAL_DBNAME = ORACLE)

        (ORACLE_HOME = D:\oracle\product\10.2.0\db_1) 

        (SID_NAME = ORACLE)

       )

    )

   4. 保存文件，然后重新启动监听服务TNSListener就可以了 ！
