【ORA-00257: archiver error. Connect internal only, until freed】

=========  删除归档日志 =========
第一步： 直接删除 物理数据 rm
第二步：通过 rman 删除:
oracle@linux112:/opt/dbbak/log_archive_dest_1> rman
RMAN> connect target sys/sys_passwd

执行如下命令：
(1)    crosscheck backup;
(2)    delete obsolete;
(3)    delete expired backup;
(4)    crosscheck archivelog all;
(5)    delete expired archivelog all;
(6)    host;

此问题属于归档日志满了。

解决办法：

SQL> select * from V$FLASH_RECOVERY_AREA_USAGE;

FILE_TYPE    PERCENT_SPACE_USED PERCENT_SPACE_RECLAIMABLE NUMBER_OF_FILES
------------ ------------------ ------------------------- ---------------
CONTROLFILE                   0                         0               0
ARCHIVELOG                  99.9                         0               3
FLASHBACKLOG                  0                         0               0

可以看出，ARCHIVELOG日志已经达到99.9%了。要把它清除掉
