3.VALUE为空时，可用archive log list;查看归档目录和log sequence
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 236
Next log sequence to archive 241
Current log sequence 241
4.查看flash recovery area的使用情况
SQL> select * from V$FLASH_RECOVERY_AREA_USAGE;
FILE_TYPE PERCENT_SPACE_USED PERCENT_SPACE_RECLAIMABLE NUMBER_OF_FILES
-------------------- ------------------ ------------------------- ----------------
CONTROL FILE 0 0 0
REDO LOG 0 0 0
ARCHIVED LOG 91.18 0 101
BACKUP PIECE .55 0 1
IMAGE COPY 0 0 0
FLASHBACK LOG 0 0 0
FOREIGN ARCHIVED LOG 0 0 0
7 rows selected.
5.计算flash recovery area已经占用的空间
SQL> select sum(percent_space_used)*3/100 from v$flash_recovery_area_usage;
SUM(PERCENT_SPACE_USED)*3/100
-----------------------------
2.7519
6.查看recovery目录
SQL> show parameter recover;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest string /oracle/app/fast_recovery_area
db_recovery_file_dest_size big integer 4182M
db_unrecoverable_scn_tracking boolean TRUE
recovery_parallelism integer 0
7.转移或清除对应的归档日志
$ cd /oracle/app/fast_recovery_area/test/archivelog --test未实例名
然后选择删除无用的archivelog
我这里因为是用来自我学习的测试环境，所以把归档日志全部删除了：
正式环境请谨慎操作！！！
$ cd /oracle/app/fast_recovery_area/test/archivelog
$ du * -sh --time
0 2022-10-13 10:07 2022_10_11
3.5G 2022-10-13 10:07 2022_10_12
262M 2022-10-13 13:36 2022_10_13
$ rm -rf *
注意:
在删除归档日志后，必须用RMAN维护控制文件，否则空间显示仍然不释放。
8.rman连接
$ rman target /
