db_recovery_file_dest_size of 10240 MB is 19.83% used. This is a
user-specified limit on the amount of space that will be used by this
database for recovery-related files, and does not reflect the amount of
space available in the underlying filesystem or ASM diskgroup.

如果需要启用failover那么需要启用flashback database：
启用闪回恢复区：
*.db_recovery_file_dest_size=10737418240
*.db_recovery_file_dest='+DATA'
select flashback_on from v$database;
得到的值有两种情况：YES 或者 NO，分别表示开启和关闭。
如果需要打开或关闭，需要在mount状态下使用下面的命令：
alter database flashback on;
