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！
