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：
sql;">
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)
(ORACLEHOME = 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！
