RMAN> backup database plus archivelog;命令的理解!
 
个人理解如下:
 
执行命令后系统 切换redo log并归档à备份归档文件(scn:604010~609123)à备份数据文件(ckp scn:609130/609129)à切换redo log并归档à备份归档文件(scn:609123~609152)à备份spfile和control file(ckp scn:609158)
 
具体操作如下:
RMAN> backup database plus archivelog;

疑问+灵感:
其实我没做copy备份,可是下面的命令能看到归档文件!那么是不是可以通过delete copy来删除归档文件呢?
答案:好像可以!
