我的主库是AIX操作系统上的oracle11g RAC

我的备库是Linux操作系统上的单实例

版本都是11.2.0.4

监听，tns，pfile等都检查过，配置正确的。

方法一：一开始我使用rman备份全库、归档、控制文件，传输到备库进行恢复的方式进行搭建，发现无法成功，报错RMAN-06172: no AUTOBACKUP found or specified handle is not a valid copy or piece，多方检查发现是异构平台的字节序问题导致的。

方法二：于是使用rman的duplicate方式直接传输，我查到这种方式会自动转换字节序，然而依然报错，看起来还是字节序的问题。报错和方法一中的一样，还是RMAN-06172: no AUTOBACKUP found or specified handle is not a valid copy or piece

注意如下报错执行过程中的这一部分，看起来是在复制主库的密码文件到备库，密码文件复制完成后的下一步就是复制主库的控制文件到备库。这里rman把主库的密码文件复制到备库后，因为字节序的原因，密码文件无法被读取，导致下一步连接不上备库，我只好在rman把密码文件复制过来的瞬间，手动复制正常字节序的密码文件把rman传过来的密码文件覆盖掉，才能让rman继续下一步。通过对这一部分的观察，我才怀疑rman在接下来复制控制文件的时候没有进行字节序转换：

“contents of Memory Script:

targetfile '/db/oracle/product/11.2.0/db/dbs/orapwmdmdb2' auxiliary format
'/u01/app/oracle/product/11.2.0/db_1/dbs/orapwmdmdb' ;
}

”

完整的报错如下：

我在这个报错后，将主库的AUTOBACKUP打开了，依然不能解决问题，怀疑rman就是没有做字节序转换：

CONFIGURE CONTROLFILE AUTOBACKUP ON;

请问我该如何解决这个问题？

我的操作步骤或者命令是不是有缺失的地方呢？
