oracle适配器连接不上的解决办法

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！
