Oracle冷备份恢复-原数据恢复

通过 oracle 10G服务器端安装以及冷备份恢复 的测试用例通过，开始恢复原数据

 

最开始，也是orapwd.ora文件的问题，直接恢复即可。

恢复之后在继续startup，检测错误

-----------------------------------------------------------------------------------

此时的错误如下

ORA-01157: cannot identify/lock data file 8 - see DBWR trace file
ORA-01110: data file 1: '------------------/gssy_neeadb.dbf'

因为数据文件已经在被使用了从而导致数据库的后台进程不能找到相应的数据文件或者不能锁定相应的数据文件，这样数据库将禁止访问这些数据文件而其他的数据文件则没有影响。伴随这个错误操作系统将会提示是哪个数据文件不能被识别。

 

看了错误解释，知道了数据文件的路劲不对，于是，我选择了删掉数据库用例，可惜删不掉，只能重装数据库，重来。

------------------------------------------------------------------------------------

 重装之后，上面的错误解决。但错误还是在继续

cmd中进入sqlplus，startup

Database mounted.

ora-01092:ORACLE instance terminated. Disconnection forced.

 

继续找解决方法：

 按照网上的说法，先看错误日志，于是找到错误日志（检查alert.log日志：D:\oracle\product\10.2.0\admin\Oracle_SID\bdump\alert.log），

有如下错误：

从以上错误信息看出，文件缺失或者损坏，看了第一个错误的地方，undotbs1.ora没有，然后看了一下数据文件

发现undotbs2.ora有，于是复制一份，改名undotbs1.ora
