Oracle12c 通过IP访问数据出现ORA-12505错误

1、新装的oracle12c 只能通过localhost来连接，通过Net Manager配置之后，如下图所示：





2、然后重启以下服务，如下图所示：

 



3、使用sql developer仍然无法通过IP连接，出现：状态: 失败 -测试失败: Listener refused the connection with the following error:

ORA-12505, TNS:listener does not currently know of SID given in connect descriptor，如下图所示：



4、编辑D:\InstallFile\Oracle12\app\Administrator\product\12.1.0\dbhome_1\NETWORK\ADMIN目录下的listener.ora文件，然后将：

# listener.ora Network Configuration File: D:\InstallFile\Oracle12\app\Administrator\product\12.1.0\dbhome_1\NETWORK\ADMIN\listener.ora

# Generated by Oracle configuration tools.

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (SID_NAME = CLRExtProc)

      (ORACLE_HOME = D:\InstallFile\Oracle12\app\Administrator\product\12.1.0\dbhome_1)

      (PROGRAM = extproc)

      (ENVS = "EXTPROC_DLLS=ONLY:D:\InstallFile\Oracle12\app\Administrator\product\12.1.0\dbhome_1\bin\oraclr12.dll")

    )

    )

  )

LISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.33)(PORT = 1521))

    )

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

    )

  )

ADR_BASE_LISTENER = D:\InstallFile\Oracle12\app\Administrator\product\12.1.0\dbhome_1\log

更改为（红色字体部分）：

# listener.ora Network Configuration File: D:\InstallFile\Oracle12\app\Administrator\product\12.1.0\dbhome_1\NETWORK\ADMIN\listener.ora

# Generated by Oracle configuration tools.

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (SID_NAME = CLRExtProc)

      (ORACLE_HOME = D:\InstallFile\Oracle12\app\Administrator\product\12.1.0\dbhome_1)

      (PROGRAM = extproc)

      (ENVS = "EXTPROC_DLLS=ONLY:D:\InstallFile\Oracle12\app\Administrator\product\12.1.0\dbhome_1\bin\oraclr12.dll")

    )
(SID_DESC =

      (GLOBAL_DBNAME = ORCL)

      (ORACLE_HOME = D:\InstallFile\Oracle12\app\Administrator\product\12.1.0\dbhome_1)

      (sid_name = ORCL)

    )

  )

LISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.33)(PORT = 1521))

    )

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

    )

  )

ADR_BASE_LISTENER = D:\InstallFile\Oracle12\app\Administrator\product\12.1.0\dbhome_1\log

保存之后重启第2步的两个服务。

5、重新进行测试，测试成功，如下图所示：



注意：此是连接数据库orcl的配置，如果是新建测数据库要重新设置。
