73.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.
答案：CD
解析：
A.归档模式后，备份不需要关闭数据库，属于热备，因此A是错误的，当然也可以关闭进行一致性备份，但不是必须关闭数据库
B.fra默认路径为$ORACLE_BASE/fast_recovery_area,不需要费的配置，因此B也是错误的
C.正确，备份的时候，是备份了一个点，然后通过归档日志执行前滚实现了完全备份
D.正确，当打开归档后
SQL> archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 77
Next log sequence to archive 77
Current log sequence 79
这里的Current log sequence将会被重置为1，也就是之前的都变成了invalid
