oracle 11gR2 ASM的asmcmd工具增加cp命令

oracle 10gR2版本中asmcmd 工具不支持cp命令,而在11g版本中已经可以实现磁盘组和文件系统之间的文件对考
You can use the cp command to:
■ Copy files from a disk group to the operating system
■ Copy files from a disk group to a disk group
■ Copy files from the operating system to a disk group
以下是11gR2版本中的测试

从asm磁盘组往文件系统/oracle目录下copy

[grid@p520:/grid/app/grid]$asmcmd cp +dgsystem/orcl/datafile/USERS.264.711892935 /oracle
copying +dgsystem/orcl/datafile/USERS.264.711892935 -> /oracle/USERS.264.711892935

[grid@p520:/grid/app/grid]$cd /oracle
[grid@p520:/oracle]$ls -l

从文件系统/oracle往asm磁盘组目录下copy

[grid@p520:/oracle]$asmcmd cp /oracle/users.bak +dgsystem/orcl/datafile
copying /oracle/users.bak -> +dgsystem/orcl/datafile/users.bak
