我的主库是RAC+ASM archive放在asm磁盘上
生成备份库时需要连接一个节点就可以了？
RMAN> run
{
allocate channel c1 device type disk format '/soft/backup/%U' connect sys/6212327@rac1;
2> 3> 4> allocate channel c2 device type disk format '/soft/backup/%U' connect sys/6212327@rac2;
5> allocate auxiliary channel ac1 device type disk format '/soft/backup/%U';
6> allocate auxiliary channel ac2 device type disk format '/soft/backup/%U';
7> duplicate target database for standby;
8> }
