You are managing an Oracle Database 11g database. You configured the database to run in
ARCHIVELOG mode. Which two statements are true in this scenario? (Choose two.)
A.You must shut down the database instance to perform the backups.
B.You must configure the Flash Recovery Area (FRA) for the database.
C.You can perform complete database backups without closing the database.
D.All the previous closed database backups including control files become invalid after you configure the
database to ARCHIVELOG mode

A.在归档模式下,可以进行数据库非一致性备份,即热备份。不需要关闭数据库来备份。
B.在归档模式下,不用必须指定快速恢复区,归档日志可以重新自己指定本地位置或远程位置来归档。
C.在归档模式下,可以进行完成的数据库备份,而不需要数据库关闭。
D.在非归档转为归档模式后,或者重新配置成归档模式,之前所有的备份,包括控制文件,都已经变为无效的,因为日志信息的序列号是重头开始的。
