ORA-00257 archiver error. 错误的处理方法

archive log 日志已满

方法/步骤

1. 1

   SecureCRT登录服务器，切换用户oracle,连接oracle

   [root@userbeta~]#
   su - oracle

   [oracle@userbeta~]$
   sqlplus /nolog

   SQL>
   connect /as sysdba

   
2. 2

   检查flash
   recovery area的使用情况,可以看见archivelog已经很大了，达到99.94

   SQL>
   select * from V$FLASH_RECOVERY_AREA_USAGE;

   
3. 3

   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;

   
4. 4

   修改FLASH_RECOVERY_AREA的空间修改为6GB，修改前确认磁盘有足够空间

   SQL>
   ALTER SYSTEM SET DB_RECOVERY_FILE_DEST_SIZE=8g;

   
5. 5

   现在来清理一下archivelog归档日志，生产环境建议备份

   查询日志目录位置

   show
   parameter recover;

   删除归档日志,USERDB是数据库实例名

   cd
   /u01/app/oracle/flash_recovery_area/USERDB/archivelog

   使用root帐户删除该目录下的文件或者备份其它地方

   
6. 6

   使用rman
   操作,内容太多，只做部分截图

   [oracle@userbeta archivelog]$
   rman

   RMAN>
   connect target sys/sys_passwd

   crosscheck
   backup;

   delete
   obsolete;

   delete
   expired backup;

   crosscheck
   archivelog all;

   delete
   expired archivelog all;

   //此步会有提示，输入
   YES 回车

   host;   //退出rman

   
7. 7

   确认是否操作成功

   #  sqlplus /nolog

   SQL>  connect /as sysdba

   SQL>
   select * from V$FLASH_RECOVERY_AREA_USAGE;

   
8. 8

   删除完成，重新连接数据库

   
   END

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;
