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

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 sys/pass

[root@sha3 oracle]# rman target sys/pass

Recovery Manager: Release 10.2.0.4.0 - Production on Tue Jan 20 01:41:26 2009

Copyright (c) 1982, 2007, Oracle.  All rights reserved.

connected to target database: tt (DBID=4147983671)

9. 检查一些无用的archivelog

RMAN> crosscheck archivelog all;

10. 删除过期的归档

RMAN> delete expired archivelog all;

delete archivelog until time 'sysdate-1' ; 删除截止到前一天的所有archivelog

11. 再次查询,发现使用率正常,已经降到23.03

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                23.03                         0              36

BACKUPPIECE                   0                         0               0

IMAGECOPY                     0                         0               0

FLASHBACKLOG                  0                         0               0

其它有用的Command:

----------------------------------

如果archive log模式下不能正常startup,则先恢复成noarchive log,startup成功后,再shutdown;

shutdown immediate;

startup mount;

alter database noarchivelog;

alter database open;

shutdown immediate;

再次startup以archive log模式

shutdown immediate;

startup mount;

show parameter log_archive_dest;

alter database archivelog;

archive log list;

alter database open;

如果还不行,则删除一些archlog log

SQL> select group#,sequence# from v$log;

GROUP# SEQUENCE#

---------- ----------

1         62

3         64

2         63

原来是日志组一的一个日志不能归档

SQL> alter database clear unarchived logfile group 1;

alter database open;

最后,也可以指定位置Arch Log, 请按照如下配置

select name from v$datafile;

alter system set log_archive_dest='/opt/app/oracle/oradata/usagedb/arch' scope=spfile

或者修改大小

SQL> alter system set db_recovery_file_dest_size=3G scope=both;
