从ASM中拷贝归档日志到文件系统:
命令：
rman target /
RMAN> copy archivelog '+ARCH/fhdbca/archivelog/2018_05_09/thread_1_seq_37.384.975668203' to '/oracle/thread_1_seq_37.384.975668203';
从文件系统中拷贝归档日志到ASM:
命令：
RMAN> catalog archivelog '/oracle/thread_1_seq_37.384.975668203';
RMAN> copy archivelog '/oracle/thread_1_seq_37.384.975668203' to '+ARCH/fhdbca/archivelog/2018_05_09/thread_1_seq_37.384.975668203';
RMAN> catalog archivelog '+ARCH/fhdbca/archivelog/2018_05_09/thread_1_seq_37.384.975668203';
ASMCMD中的cp命令(11g)
cp命令是11g新增的命令，使用它可以轻松的把文件从ASM中复制到文件系统中或者反过来。还可以把ASM中的文件复制到网络上的其他服务器的文件系统中。
