Oacle数据库启动不起来了,,一启动就死机,经过多次测试差错发现是磁盘损坏,导致UNDOTBS01.DBF数据文件无法访问,访问就死机。无奈用冷备份的办法,将数据库迁移到另一台主机上。

Oracle 11g, 安装在windows XP上,只是作为平时开发用的数据库,没有多少维护,也没有开启归档日志模式。(注:由于操作时没有保存操作信息,也没有可用的测试环境了,所以都是凭记忆还原步骤,不排除有不正确的操作和命令,仅作参考。)

Step 1. 首先在目标主机上安装Oracle 11g(和源数据库相同),创建和源数据库相同SID的数据库。

Step 2. 查找源数据库里的数据文件、REDO日志文件、控制文件、启动参数文件。
