标签归档：asm file number

前段时间有多个朋友问我,在amdu中,如果数据文件命名不是omf的方式,该如何找出来数据文件的asm file_number,从而实现通过amdu对不能mount的磁盘组中的数据文件进行恢复,这里通过测试给出来处理方法.根据我们对asm的理解,asm file_number 6为asm file的别名文件记录所在地,我们通过分析kfed这些au中的记录即可获得相关数据文件的别名对应的asm文件号

从sql查询,我们可以确定xifenfei0n.dbf对应的文件号分别为:xifenfei01.dbf==>266,xifenfei02.dbf==>267,xifenfei03.dbf==>268

通过上述分析我们发现目前数据主要分布在au=26,block in(0-6)的几个block中,通过kfed已经找出来了所有的asm中文件的file_number

非win平台脚本实现

for (( i=0; i<255; i++ ))
do
   kfed read H:\ASMDISK\ASMDISK1.DD aun=26 blknum=$i 
  \|egrep 'name|fnum'|grep -v length=0 |grep -v 0x00000000 >>asm_file.out
done

注意需要按照file 6的au依次处理,否则会不全,更加简单的方法,直接通过dul扫描磁盘获取相关file number
