重建控制文件，并且不干净的关闭数据库测试：
数据库SHUTDOWN ABORT，删除CONTROLFILE

显然这里缺少102这个归档，因为他是当前日志文件，所以我们需要把日志复制到归档目录下，但是那个日志是102呢，这样就可以确定
[oracle@localhost bdump]$ tail -n 4000 alert_xuexi.log |grep Current

Current log# 7 seq# 102 mem# 2: /oradata/logfile07.log
可以确认/oradata/logfile07.log就是需要的归档
cp /oradata/logfile07.log /archive/1_102_822387818.dbf

AUTO
完成后即可
当然也快手动输入你确认的当前归档如下：
