ORA-00257 archiver error. 錯誤的處理方法
archive log 日誌已滿
方法/步驟
- 1
SecureCRT登錄服務器,切換用戶oracle,連接oracle
[root@userbeta~]# su - oracle
[oracle@userbeta~]$ sqlplus /nolog
SQL> connect /as sysdba
- 2
檢查flash recovery area的使用情況,可以看見archivelog已經很大了,達到99.94
SQL> select * from V$FLASH_RECOVERY_AREA_USAGE;
- 3
計算flash recovery area已經占用的空間
SQL> select sum(percent_space_used)*3/100 from v$flash_recovery_area_usage;
- 4
修改FLASH_RECOVERY_AREA的空間修改為6GB,修改前確認磁盤有足夠空間
SQL> ALTER SYSTEM SET DB_RECOVERY_FILE_DEST_SIZE=8g;
- 5
現在來清理一下archivelog歸檔日誌,生產環境建議備份
查詢日誌目錄位置
show parameter recover;
刪除歸檔日誌,USERDB是數據庫實例名
cd /u01/app/oracle/flash_recovery_area/USERDB/archivelog
使用root帳戶刪除該目錄下的文件或者備份其它地方
- 6
使用rman 操作,內容太多,只做部分截圖
[oracle@userbeta archivelog]$ rman
RMAN> connect target sys/sys_passwd
crosscheck backup;
delete obsolete;
delete expired backup;
crosscheck archivelog all;
delete expired archivelog all;
//此步會有提示,輸入 YES 回車
host; //退出rman
- 7
確認是否操作成功
# sqlplus /nolog
SQL> connect /as sysdba
SQL> select * from V$FLASH_RECOVERY_AREA_USAGE;
- 8
刪除完成,重新連接數據庫
END
ORA-00257:
archiver error. Connect internal only, until freed 錯誤的處理方法
1. 用sys用戶登錄
sqlplus sys/pass@tt as sysdba
2. 看看archiv log所在位置
SQL> show parameter log_archive_dest;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
log_archive_dest string
log_archive_dest_1 string
log_archive_dest_10 string
3. 一般VALUE為空時,可以用archive log list;檢查一下歸檔目錄和log sequence
SQL> archive log list; Database log mode Archive Mode Automatic archival Enabled Archive destination USE_DB_RECOVERY_FILE_DEST Oldest online log sequence 360 Next log sequence to archive 360 Current log sequence 362
4. 檢查flash recovery area的使用情況,可以看見archivelog已經很大了,達到96.62
SQL> select * from V$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. 計算flash recovery area已經占用的空間
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目錄, 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 上述結果告訴我們,歸檔位置用的是默認值,放在flash_recovery_area下(db_recovery_file_dest目錄=/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
轉移或清除對應的歸檔日誌, 刪除一些不用的日期目錄的文件,註意保留最後幾個文件(比如360以後的)
---------------------------------------------------------------------------------------
註意:
在刪除歸檔日誌後,必須用RMAN維護控制文件,否則空間顯示仍然不釋放。
---------------------------------------------------------------------------------------
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. 檢查一些無用的archivelog
RMAN> crosscheck archivelog all;
10. 刪除過期的歸檔
RMAN> delete expired archivelog all;
delete archivelog until time ‘sysdate-1‘ ; 刪除截止到前一天的所有archivelog
11. 再次查詢,發現使用率正常,已經降到23.03
