本文探讨了RMAN中过期备份的处理方式，包括列出和删除过期备份的命令及其对备份集片段的影响。过期的备份集片段通常不存在，通过crosscheck命令发现并标记为过期，使用list expired backup命令报告这些记录，而delete expired backup命令则在控制文件和恢复目录中标记备份元数据为已删除状态。

You run the following commands:
RMAN> list expired backup;
RMAN> delete expired backup;
What will happen to the backup set pieces associated with the backups that appear in the list expired backup command?
A. They will be renamed.
B. Nothing will happen to them. The backup set pieces do not exist.
C. They will be deleted immediately since they are not in the flash recovery area.
D. You will need to manually remove the physical files listed in the output of the commands.
E. They will become hidden files and removed 10 days later.

　　Expired backup set pieces are those backup set pieces that do not exist.They are discovered via the crosscheck command and marked as expired.The list expired command reports backup set records that are marked as expired.The delete expired backup command marks the backup metadata in the control file and recovery catalog with a status of DELETED.
