sql - 通过 SQL Developer 连接时出现 ora-12505 错误

Question

我正在尝试使用 SQL Developer 远程连接到 Oracle 12c 数据库。为了从另一台计算机进行远程连接，我在运行 Oracle 的计算机上在 Windows 7 防火墙中打开了一个端口。该部分有效，但现在由于此错误 ORA-12505，监听器不让我进入。当我尝试连接远程计算机中的 SQL Developer 时，它说它无法识别我提供的 SID。我什至尝试将服务名称设置为“editor”，但仍然没有任何结果。

以下是远程计算机上 SQL Developer 的设置:

在服务器端，这是listener.ora:

SID_LIST_LISTENER =
(SID_LIST =
  (SID_DESC =
    (SID_NAME = CLRExtProc)
    (ORACLE_HOME = C:\app\Owner\product\12.1.0\dbhome_1)
    (PROGRAM = extproc)
    (ENVS = "EXTPROC_DLLS=ONLY:C:\app\Owner\product\12.1.0\dbhome_1\bin\oraclr12.dll")
  )
)

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
      (SERVICE_NAME = editor)
    )
 )

 REMOTE_LISTENER =
   (DESCRIPTION_LIST =
     (DESCRIPTION =
       (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.19)(PORT = 1531))
       (SERVICE_NAME = editor)
     )
   )

和 tnsnames.ora:

EDITOR =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.19)(PORT = 1531))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = editor)
    )
  )

  LISTENER_EDITOR =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
      (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = editor)
    )
  )


  ORACLR_CONNECTION_DATA =
    (DESCRIPTION =
      (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
    )
  )

您会注意到默认监听器设置为端口 1521 上的 localhost。只要保持这种状态，我就可以使用 SQL Developer 连接到服务器。因此，为了远程连接，我为端口 1531 设置了第二个监听器，并输入了服务器的 IP 地址。防火墙也已设置为允许通过端口 1531 进行连接。如您所见，我确实对 tnsnames.ora 文件进行了一些编辑，以允许连接到编辑器数据库，但我的编辑似乎没有修复任何问题。我仍然无法在客户端连接 SQL Developer。在服务器上，我尝试使用 Oracle Net Configuration Assistant 来测试编辑器条目，但出现错误消息:

ORA-12514 监听器当前不知道连接描述符中请求的服务。

系统要求我从命令提示符运行 lsnrctl status。以下是该命令的输出:

好吧...那我该怎么办呢？？？

Answer 1

不要使用 SID，使用 SERVICE - 从您的示例中显示，“编辑器”。

在 12c 上，如果您要连接到可插拔设备，那么您将始终需要使用服务。 SID 将解析为容器数据库 (CDB)。

要确认这是正确的，请在服务器上运行“lsnrctl status”命令，并检查监听器正在监听的实际服务。
