（1）RMAN 异机恢复的时候，。如果说要想改成其他的实例名，。实例名的信息会记录到控制文件里，所以如果在恢复的时候，如果实例名不一致，恢复的时候会报错。
（2）如果恢复的路径和源库不一致，就需要在restore时用set 命令指定新位置。并且使用switch datafile all将信息更新到控制文件中。
在做duplicate的时候，RMAN 会自动根据pfile中的log_file_name_convert和db_file_name_convert来进行set 的转换。手工restore时，只能使用set 命令转换。
（3）异机恢复对相同目录和不同目录都做了说明。
（4）最后测试了NID 修改DBID 和DBNAME.
