1.IP错误。 在设置URL时错误,例如:jdbc:oracle:thin:@192.168.0.36:1521:sharp 数据库服务器不正确:ping 服务器IP是否正确。不正确,将URL更改为正确 端口号错误:一般不会错误。 进行一下操作:在DOS上键入sqlplus,检查oracle是否开启 一却正常,执行下面第2步。
2.防火墙 如果机器上安装有放火墙,可能是服务器端口号屏蔽而造成的。关闭防火墙后,尝试重新连接。 仍然不行,执行第3步。
3.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
