Oracle recovery manager failed to restore

解决办法：

1：清理过期失效的备份，

2：增加recovery_file_dest_size参数值即可；

SQL> show parameter db_recover

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest                string      /oracle/flash_recovery_area
db_recovery_file_dest_size           big integer 2G
SQL> alter system set db_recovery_file_dest_size=4G scope=spfile;

System altered.
