oracle報ORA-00257的解決辦法

OAR-00257 aichivelog歸檔錯誤

• 登錄服務器，切換oracle

  su -oracle;
  sqlplus /nolog;
  SQL> conn /as sysdba;
  

• 檢查fast_recovery_area的使用情況

  SQL> select * from V$FLASH_RECOVERY_AREA_USAGE;
  

• 計算fast_recovery_area已經占用的空間

  SQL> select sum(percent_space_used)*3/100 from v$flash_recovery_area_usage;
  

• 修改fast_recovery_aread的空間

  SQL> ALTER SYSTEM SET DB_RECOVERY_FILE_DEST_SIZE=8g;
  

• 查詢日志目錄位置

  SQL> show parameter recover;
  cd /u01/app/oracle/flash_recovery_area/USERDB/archivelog
  ##USERDB是數據庫實例名
  

• 退出sql編輯模式

  exit
  

• rman操作日志

  rman
  

  RMAN> connect target sys/sys_passwd
  
  crosscheck backup; 
  
  delete obsolete; 
  
  delete expired backup; 
  
  crosscheck archivelog all; 
  
  delete noprompt archivelog all; 
  

  host;   //退出rman
  

---

歸檔日志定時清理

• 新建歸檔日志腳本

  [oracle@localhost ~]$ vim /home/oracle/del_arch.sh
  #!/bin/bash
  echo "----------------------------------------`date`---------------------------------------"
  source ~/.bash_profile
  rman target / <<EOF
  crosscheck archivelog all;
  delete noprompt expired archivelog all;
  delete noprompt archivelog all completed before 'sysdate-7';
  EOF
  echo -e "\n"
  echo "------------------------------------ FINISHED ------------------------------------"
  

• 將腳本添加到定時任務當中

  [oracle@localhost ~]$ crontab -e
  * 1 * * *  sh /home/oracle/del_arc.sh
