文件系统拷贝到asm上
有很多迁移的情况都是要将文件系统上的数据文件拷贝到asm上面，所以做了个测试。
1，配置两个库的密码文件$ORACLE_HOME/dbs
2，源库mount目标库nomount
3，使用单个文件的方式拷贝
cnsz130664:um2 > rman
RMAN> connect target sys/sys
connected to target database: UM2 (DBID=1036225299)
using target database control file instead of recovery catalog
RMAN> connect auxiliary sys/sys@hd01um2
connected to auxiliary database: HD01UM2 (not mounted)
RMAN> backup as copy reuse datafile 1 auxiliary format '+DATA_DG';
Starting backup at 2012-05-28 19:34:39
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=72 device type=DISK
channel ORA_DISK_1: starting datafile copy
input datafile file number=00001 name=/data02/impdp_temp/hd01um2/system.309.779387751
output file name=+DATA_DG/hd01um2/datafile/system.369.784496083 tag=TAG20120528T193440
channel ORA_DISK_1: datafile copy complete, elapsed time: 00:00:56
Finished backup at 2012-05-28 19:35:36
RMAN> exit
或者可以使用全库拷贝的方式，将所有的数据文件都拷贝到asm磁盘中
run
{
allocate channel c1 type disk;
allocate channel c2 type disk;
allocate channel c3 type disk;
allocate channel c4 type disk;
backup as copy database auxiliary format '+STG_DATA_DG';
release channel c1;
release channel c2;
release channel c3;
release channel c4;
}
注意: 11g的target不能使用connect target /这种方式连接，否则会出现用户名或者密码错误。

另外必须保证asm磁盘空间足够，否则会出现一部分拷贝成功一部分拷贝失败！
