从+DATA迁移到+newdata磁盘组
---归档模式：
1.利用copy备份数据库
rman>backup as copy database format '+DG1'
2.待备份完，启动到mount状态(启动第一节点数据库到mount,其它节点数据库实例关闭)
SQL> shutdown immediate
SQL> startup mount;
P750a:/home/oracle$export ORACLE_SID=lixora1

----结果确认：
select file_name from dba_data_files;
后续要做的事情：
在新dg 上创建temp 文件；redo log 切换到新dg；spfile 位置dg上的位置调整；
