===================================

我的oracle一直是正常的，后来公司停电过后，出了点小问题·～～

数据库监听未启动 修改PC上注册表中的ImagePath值。
我下面以现在主流的数据库ORACLE为例
重新手动启动数据库监听：
1：开始 → 运行→ 输入CMD→ 进入DOS命令提示界面
d:>lsnrctl
LSNRCTL> status
或者
LSNRCTL> start
也有可能连接Url出错 服务器链接出错

start后出现：

Starting tnslsnr: please wait...

Service OracleOraDb10g_home1TNSListener already running.
TNS-12560: TNS:protocol adapter error
