解压后，我门只需要对asmdisk.txt这个配置文件进行下设置，只需要设置磁盘号和路径，我们可以通过kfod di=all得到，如下；
[oracle@rac01odu]$ kfod di=all

进入odu的asmcmd工具，具体操作如下：
[oracle@rac01odu]$ ./odu

至此，我们就进入了ODU的ASMCMD工具中，这个工具的命令数据库自带的有所细微的区别，给演示下我们如何利用它查询数据文件的文件号：
ASMCMD>cd+data
ASMCMD>cd ORCL
Currentdirectory: +DATA/ORCL
ASMCMD>ls
Currentdirectory: +DATA/ORCL/DATAFILE

ASM实例中所有文件，都有自己的文件号，如上面每个文件的后缀中的数字，后续我们就根据文件号，利用amdu抽取出数据文件。
3. 利用amdu抽取数据文件
这里我们尝试控制文件文件抽取出来，让数据库能够启动到mount状态
ASMCMD>cdcontrolfile
Currentdirectory: +DATA/ORCL/CONTROLFILE
ASMCMD>ls
Currentdirectory: +DATA/ORCL/CONTROLFILE
Name
----------------------------------------
Current.261.883666805
Current.260.883666805
这里我们就看到了，控制文件的文件号是260和261，接下来通过amdu进行数据抽取
[oracle@rac01~]$ amdu -diskstring '/dev/asm*' -extract data.260
amdu_2015_07_23_16_15_50/
[oracle@rac01~]$ amdu -diskstring '/dev/asm*' -extract data.261
amdu_2015_07_23_16_16_01/
可以看到，生成了2个文件夹，进入其中的一个
[oracle@rac01~]$ cd amdu_2015_07_23_16_15_50/
[oracle@rac01amdu_2015_07_23_
