Question

我尝试连接到Oracle 11g，但这是发生的事情，而不是第一次。

侦听器拒绝连接时出现以下错误：
ORA-12505，TNS：监听器当前不知道连接描述符供应商代码12505中给出的SID。

这是 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 = DESKTOP-EJG24HE)(PORT = 1521))
        )
      )

    DEFAULT_SERVICE_LISTENER = (XE)

和 tnsnames.ora

    XE =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = DESKTOP-EJG24HE)(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) 
    ) 
  )

我试图用它做点什么，但我无法理解问题出在哪里。

其他信息：

SQL>  show parameter service_names

SQL> show parameter local_listener

SQL> alter system set LOCAL_LISTENER='(ADDRESS=(PROTOCOL=TCP)(HOST=DESKTOP-EJG24HE)(PORT=1521))' scope=both;

我试图检查听众和其他人的状态，但它不像我朋友的程序那样正常。

无法连接到Oracle 11g XE，因为侦听器当前不知道SID
