我准备搭建一套oracle 11g 的dg。主库是AIX上的双节点RAC，备库是虚拟机上的linux单实例。

主库上使用rman备份了全库、归档、控制文件，命令如下：

全库备份：backup as compressed backupset database format='/backup/rmanbak/bak/${ORACLE_SID}_%Y-%M-%D_%U.full';

归档备份：backup as compressed backupset archivelog all format='/backup/rmanbak/bak/${ORACLE_SID}_%Y-%M-%D_%U.arc';

控制文件备份：backup device type disk format '/backup/rmanbak/standby_%U.ctl' current controlfile for standby;

查看主库上备份的控制文件的权限：

# ls -l /backup/rmanbak

-rw-r----- 1 oracle asmadmin 24903680 Mar 24 15:43 standby_ff3l5kkb_1_1.ctl

使用sftp传输备份到备库，赋权

chown -R oracle:oinstall /data/rmanbak

查看备库上的备份的权限：

[root@mdmdb rmanbak]# ls -l /data/rmanbak/
-rw-r--r-- 1 oracle oinstall 24903680 Mar 24 15:43 standby_ff3l5kkb_1_1.ctl

备库使用rman恢复控制文件：

[oracle@mdmdb rmanbak]$ rman target /

在主库上备份的文件都是 asmadmin组的，备库上没有这个组，我在备库新建了这个组并把oracle用户加入进去，然后授权控制文件的备份为oracle:asmadmin，再恢复依然报RMAN-06172: 

不知道到底是哪里的问题，希望能得到大神的指点
