Caused by: oracle.net.ns.NetException: Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor
还原系统几次了，搞死人了都没好 有经验的朋友帮帮忙
请不要贴百度搜来的东西，希望是有经过实践的
D:\app\Administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN
listener.ora
内容如下
# listener.ora Network Configuration File: D:\app\Administrator\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.
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")
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
)
ADR_BASE_LISTENER = D:\app\Administrator
网上说改这个文件，貌似没啥效果。
连接字符串绝对没问题，pl/sql连127.0.0.1：1521/orcl报错ORA-12514
不要贴百度搜来的东西，可以谈下经验，谢谢各位！

以前安装oracle后为了进入到console页面，重装了2次系统。才勉强能进 现在发现安装oracle真的很不容易。
