Oracle数据库恢复问题
之前做数据库备份的实验时，是数据库热备份。恢复过来的时候遇到问题，如图： 上图问题恢复之后，打开数据库，要求使用resetlogs，按照提示在mount状态执行alter database open resetlos！！ 然后说system01.dbf文件没有恢复过来，然后执行recover database
之前做数据库备份的实验时，是数据库热备份。恢复过来的时候遇到问题，如图：
上图问题恢复之后，打开数据库，要求使用resetlogs，按照提示在mount状态执行"alter database open resetlos"！！
然后说system01.dbf文件没有恢复过来，然后执行"recover database using backup controlfile until cancel"，然后再指定日志那里输入文件名（包括路径），或者按照提示输入auto
最后执行"alter database open"打开数据库
这个问题可能是恢复之后，打开时，oracle服务器根据控制文件和日志文件的一些地方不对应造成的！！
