ORA-00257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?/ 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$FLASH_RECOVERY_AREA_USAGE;
FILE_TYPE??? PERCENT_SPACE_USED PERCENT_SPACE_RECLAIMABLE NUMBER_OF_FILES
------------ ------------------ ------------------------- ---------------
CONTROLFILE???????????????? .13??????????????????????? 0?????????????? 1
ONLINELOG????????????????? 2.93??????????????????????? 0?????????????? 3
ARCHIVELOG??????????????? 96.62?????????????????????? 0????????????? 141
BACKUPPIECE?????????????????? 0???????????????????????? 0?????????????? 0
IMAGECOPY????????????????????? 0???????????????????????? 0?????????????? 0
FLASHBACKLOG??????????????? 0???????????????????????? 0?????????????? 0
5. 计算flash recovery area已经占用的空间
SQL> select sum(percent_space_used)*3/100 from v$flash_recovery_area_usage;
SUM(PERCENT_SPACE_USED)*3/100
-----------------------------
?????????????????????? 2.9904
????????????????????
6. 找到recovery目录,show parameter recover
SQL> show parameter recover;
NAME???????????????????????????????? TYPE??????? VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest??????????????? string?????????? /u01/app/oracle/flash_recovery_area
db_recovery_file_dest_size??????? big integer?? 5G
recovery_parallelism?????????????????? integer???????? 0
????????????????????
7 上述结果告诉我们，归档位置用的是默认值，放在flash_recovery_area下(db_recovery_file_dest目录=/u01/app/oracle/flash_recovery_area)
[root@sha3 10.2.0]# echo $ORACLE_BASE
/u01/app/oracle
[root@sha3 10.2.0]# cd $ORACLE_BASE/flash_recovery_area/tt/archivelog
转移或清除对应的归档日志,删除一些不用的日期目录的文件，注意保留最后几个文件（比如360以后的）
---------------------------------------------------------------------------------------
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 target?/
[root@sha3 oracle]# rman target?/
