设定恢复区大小：
SQL> show parameter recover;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest string /u01/app/oracle/fast_recovery_
area
db_recovery_file_dest_size big integer 11182M

清理归档：
crosscheck archivelog all;
delete noprompt expired archivelog all;
delete noprompt archivelog all completed before 'sysdate-3';
重新设置闪回区大小：
SQL> alter system set db_recovery_file_dest_size =30G;
System altered.
SQL> show parameter recover;
