RMAN-06585: no copy of datafile 7 found 问题解决

 RMAN-06585: no copy of datafile 7 found 问题解决

今天在学习backup  copy of 命令时出现 RMAN-06585: no copy of datafile 7 found错误，研究了好长时间，才解决，原来是自己看文档不够仔细造成的。

This form of backup is used to back up a database backup created as image copies on disk to tape

 

总结：在使用backup  copy of 命令前必须要确保被备份的文件或者数据库在disk存在其镜像（可以使用backup as copy先制作其镜像），   然后才能使用backup  copy of 命令 ，因为该命令是对存在的镜像文件再次制作镜像文件，做之前一定要确保镜像文件的存在，切记！！

 

下面的试验过程：

如上面报的错误理解，backup copy of database 命令是对数据库的镜像文件再制作镜像文件，
上面检查了检查了确实没有数据库的镜像文件，下面使用backup as copy database命令来制作数据库的镜像文件，过程如下：
RMAN> backup as copy database;
