ORA-00257 archiver error. 错误的处理方法

转一位大神的笔记。

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;    #
检查控制文件和实际物理文件的差别
10. 删除过期的归档
RMAN> delete expired archivelog all;   # 
delete expired删除的是那些本来RMAN以为存在但是实际上在磁盘或者磁带上已经被删除了的信息,删除的只是RMAN资料库中的记录
                      # delete archivelog until time 'sysdate-1' ;  
删除截止到前一天的所有archivelog

                      # delete obsolete则删除旧于备份保留策略定义的备份数据同时也更新RMAN资料库以及控制文件

                      参考:http://blog.chinaunix.net/uid-27570589-id-4237145.html

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;
