无法配置 Oracle 本地 DB ORA-12505，TNS:listener 目前不知道连接描述符中给出的 SID

Question

我已经在我的机器上安装了 oracle 11g express edition 并使用 Run SQL COMMAND LINE 成功添加了用户并授予访问权限，但是我无法使用 SQL DEVELOPER 对其进行配置，这就是我遇到上述错误的地方。我将我的配置（tnsnames.ora 和 listener.ora）与其他工​​作机器进行了比较，发现配置相同。

我也可以再访问这个网站http://127.0.0.1:8080/apex/f?p=4950:1:384148910814731

tnsname.ora

    XE =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = win)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
    )
  )

EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )

ORACLR_CONNECTION_DATA = 
  (DESCRIPTION = 
    (ADDRESS_LIST = 
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1)) 
    ) 
    (CONNECT_DATA = 
      (SID = CLRExtProc) 
      (PRESENTATION = RO) 
    ) 
  ) 

listener.ora

    SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
      (PROGRAM = extproc)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = win)(PORT = 1521))
    )
  )

DEFAULT_SERVICE_LISTENER = (XE)

感谢您的回复，真的很感激，但幸运的是我解决了它，我删除了 C:\Windows\System32\drivers\etc 上的 IP 和 PC 名称。
