oracle 的Developer连接不上报错：listener does not currently know of SID given in connect descriptor

解决办法：

在 D:\app\Administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN中找到listener.ora文件，修改后的文件在“下面”中，复制并覆盖就ok了。

# listener.ora Network Configuration File: D:\app\Administrator\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

把listener.ora中的配置改成如下即可：

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = D:\app\Administrator\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )


    (SID_DESC =  
      (GLOBAL_DBNAME = orcl)  
      (ORACLE_HOME =  D:\app\Administrator\product\11.2.0\dbhome_1)  
      (SID_NAME = orcl)  
    ) 
  )


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


ADR_BASE_LISTENER = D:\app\Administrator

如按照以上操作还是连接不上，可能是你的SID错误！
