The Network Adapter could not establish the connection网络适配器无法连接

由 落花浮王杯 提交于 2019-12-13 05:05:13
The Network Adapter could not establish the connection。网络适配器无法连接 启动项目时，oracle连接报错 几个错误原因和解决办法： 1、IP错误：数据源配置时数据库服务器的ip或者端口号填写错误。 数据库服务器是否正确：ping 服务器IP是否通畅。ping不通则将URL更改正确。 端口号是否正确。 进行一下操作：在DOS上键入sqlplus，检查oracle是否开启 一切正常则执行下面第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。 你的防火墙可能开启，然后不允许你的端口号通过，所以你选择关闭防火墙或者开启你的端口。windows开启端口有点麻烦。所以建议关闭防火墙尝试。 Linux查询端口号是否开启的指令：firewall-cmd --query-port=端口号/tcp Linux开启端口号指令：firewall-cmd --add-port=端口号/tcp 仍然不行则执行第3步。 3、数据库监听器未启动 修改PC上注册表中的ImagePath值。 下面以ORACLE数据库为例 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
