在我们恢复的时候，发现中间缺失归档，大部分dba认为从缺失的归档开始以后的归档都无法进行恢复。但是我们从非常规的方式，修改数据文件对应的信息是可以跳过该缺失的归档，并且利用后面的归档进行恢复的。
SYS@orcl11g>recover datafile 6;
ORA-00279: change 2054392 generated at 10/28/2014 23:20:14 needed for thread 1
ORA-00289: suggestion : /opt/oracle/flash_recovery_area/ORCL11G/archivelog/2014_10_28/o1_mf_1_150_b50rqvq8_.arc
ORA-00280: change 2054392 for thread 1 is in sequence #150
Specify log: {=suggested | filename | AUTO | CANCEL}
ORA-00326: log begins at change 2055246, need earlier change 2054392
ORA-00334: archived log: '/opt/oracle/flash_recovery_area/ORCL11G/archivelog/2014_10_28/o1_mf_1_150_b50rqvq8_.arc' 这里我们发现对应的归档文件已经丢失，无法进行恢复
这里我们通过bbed只需要修改两个地方即可跳过该归档，使用下一个归档进行恢复：
