You configured the Flash Recovery Area (FRA) for your database. The database instance is running in ARCHIVELOG mode. The default location for the archived redo log files is the Flash Recovery Area.
Which two files are removed automatically if the space is required in the FRA as per the retention policy?
(Choose two.)
A.flashback log files
B.backups that have become obsolete
C.copies of the data files and control files
D.archived redo log files that have multiple copies in a different archive location and not backed up

快速恢复区的空间管理由备份保留策略控制。保留策略确定文件何时过时,即何时这些文件对达到数据恢复目标已不再有用。 Oracle DB 通过删除不再需要的文件自动管理该存储。
