【ASM】asm从共享磁盘复制到本地磁盘中

将ASM里面的文件copy到文件系统

数据文件存放在ASM里面查看不是很直观，有时候需要把文件从ASM里面copy到文件系统。我记录了一下两种方法，还有一种用AMDU，ODU也可以实现

1. 直接在asmcmd里面用cp命令   --这个命令在oracle10g的rac是不能用的，11g是没有问题的

ASMCMD> ls   

SYSAUX.260.894187589

SYSTEM.259.894187575

UNDOTBS1.261.894187601

UNDOTBS2.263.894187615

USERS.264.894187621

USERS.268.895081225

USERS.269.895582787

USERS.280.898078315

ASMCMD> cp SYSAUX.260.894187589 /home/grid/sysaux.dbf

copying +datadg01/xedb/datafile/SYSAUX.260.894187589 -> /home/grid/sysaux.dbf

[root@rac01test grid]# pwd

/home/grid

You have new mail in /var/spool/mail/root

[root@rac01test grid]# ll

sysaux.dbf

这里sysaux.dbf就是copy出来的文件

2.用rman copy命令    --这个命令也有局限性。只能copy一下内容：

archivelog, backup, check, controlfilecopy, current, datafile, datafilecopy, keep, (, level, nochecksum, nokeep, reuse, tag

2.1 rman  copy 归档

copy archivelog '+ARCH_DG/arc1/1_1216_894187568.dbf' to '/tmp/log/1_1216_894187568.dbf';

2.1 rman copy 数据文件

RMAN> copy datafile  '+DATADG01/xedb/datafile/system.259.894187575' to '/home/oracle/system.dbf'

 system.dbf

这里的system文件就是copy出来的
