oracle – TNS-12505：TNS：侦听器当前不知道连接描述符中给出的SID

我试图从NetBeans连接到Oracle 10.2.0，使用以下连接字符串：

jdbc:oracle:thin:@localhost:1521:XE

最奇怪的部分是，一切工作正常，直到一个重新启动。我开始得到这个TNS-12505错误所有的时间;看看我的listener.log中的最终条目：

前三个条目是我尝试从NetBeans连接。第四，通过sql * Plus连接，工作得很好。

这里是我的listener.ora的内容：

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = D:\oraclexe\app\oracle\product\10.2.0\server)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = D:\oraclexe\app\oracle\product\10.2.0\server)
      (PROGRAM = extproc)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
      (ADDRESS = (PROTOCOL = TCP)(HOST = brodyaga-PC)(PORT = 1521))
    )
  )

DEFAULT_SERVICE_LISTENER = (XE)

和tnsnames.ora：

XE =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = brodyaga-PC)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
    )
  )

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

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

并从> lsnrctl服务

C:\Users\brodyaga>lsnrctl services

两个Oracle服务都启动，sql * Plus连接良好。

这个错误有一些解决方法吗？

您需要为XE添加SID条目，以便向侦听器注册实例。

安装Oracle XE后，一切看起来不错，但是当你发布

C:\>sqlplus / as sysdba
sql>shutdown immediate
sql>startup

TNS-12505: TNS:listener does not currently kNow of SID given in connect descriptor

该实例将不会向侦听器注册。

所以，请编辑您的listener.ora这样：

SID_LIST_LISTENER =
  (SID_LIST =
     (SID_DESC =
       (SID_NAME = XE)
       (ORACLE_HOME = C:\oraclexe\app\oracle\product\10.2.0\server)
     )
     (SID_DESC =
        (SID_NAME = PLSExtProc)
        (ORACLE_HOME = D:\oraclexe\app\oracle\product\10.2.0\server)
        (PROGRAM = extproc)
     )
     (SID_DESC =
       (SID_NAME = CLRExtProc)
       (ORACLE_HOME = D:\oraclexe\app\oracle\product\10.2.0\server)
       (PROGRAM = extproc)
     )
  )

当我在Windows 7上安装Oracle XE时，出现了此问题。在Windows XP上没有遇到此问题。一般来说，这个条目不应该是必需的，因为实例应该自动注册到监听器。在Linux(Fedora)上运行Oracle XE，无需将XE添加到sid列表。
