racle 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\..\dbhome_\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\..\dbhome_\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\..\dbhome_) 
   (PROGRAM = extproc) 
   (ENVS = "EXTPROC_DLLS=ONLY:D:\app\Administrator\product\..\dbhome_\bin\oraclr.dll") 
  ) 
 
  (SID_DESC =  
   (GLOBAL_DBNAME = orcl)  
   (ORACLE_HOME = D:\app\Administrator\product\..\dbhome_)  
   (SID_NAME = orcl)  
  )  
 ) 
LISTENER = 
 (DESCRIPTION_LIST = 
  (DESCRIPTION = 
   (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC)) 
   (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = )) 
  ) 
 ) 
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！
