ORA-00257 archiver error. 错误的处理方法

archive log 日志已满
ORA-00257: archiver error. Connect internal only, until freed 错误的处理方法
1. 用sys用户登录
  sqlplus sys/pass@tt as sysdba
2. 看看archiv log所在位置
SQL> show parameter log_archive_dest;
NAME                                     TYPE        VALUE
------------------------------------ ----------- ------------------------------
log_archive_dest                   string
log_archive_dest_1               string
log_archive_dest_10             string
3. 一般VALUE为空时，可以用archive log list;检查一下归档目录和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     360
Next log sequence to archive  360
Current log sequence              362
4. 检查flash recovery area的使用情况,可以看见archivelog已经很大了，达到96.62
SQL> select * from V$FLASH_RECOVERY_AREA_USAGE;
FILE_TYPE    PERCENT_SPACE_USED PERCENT_SPACE_RECLAIMABLE NUMBER_OF_FILES
------------ ------------------ ------------------------- ---------------
CONTROLFILE                 .13                        0               1
ONLINELOG                  2.93                        0               3
ARCHIVELOG                96.62                       0              141
BACKUPPIECE                   0                         0               0
