oracle 数据库rac环境归档日志满了处理方法
报错如下 ORA-00257: archiver error, Connect internal only, until freed.
在这里插入图片描述

一、处理步骤
1、使用终端登录上服务器查看磁盘使用状态
[root@rac1 ~]# su - grid
grid@+ASM1:/home/grid$ asmcmd lsdg
State    Type    Rebal  Sector  Block       AU  Total_MB  Free_MB  Req_mir_free_MB  Usable_file_MB  Offline_disks  Voting_files  Name
MOUNTED  EXTERN  N         512   4096  1048576    409600      127                0             127              0             N  ARCH/
MOUNTED  EXTERN  N         512   4096  1048576   1662976   997139                0          997139              0             N  DATA/
MOUNTED  NORMAL  N         512   4096  1048576     30720    29794            10240            9777              0             Y  OCRDG/
2、使用恢复备份管理工具RMAN删除归档日志
[root@rac1 ~]# su - oracle
Password: 
oracle@orcl1:/home/oracle$rman target /

二、详细操作步骤

[root@rac1 ~]# su - grid
grid@+ASM1:/home/grid$ asmcmd lsdg
State    Type    Rebal  Sector  Block       AU  Total_MB  Free_MB  Req_mir_free_MB  Usable_file_MB  Offline_disks  Voting_files  Name

三、定时任务自动清归档日志

1、编写删除脚本
mkdir /root/delOracleLog
mkdir /root/delOracleLog/log
cd /root/delOracleLog
chmod 777 /root/delOracleLog -R
vi del_ora_log.rman
crosscheck archivelog all;
delete noprompt expired archivelog all;
delete noprompt archivelog until time 'sysdate-20'; #清理20天之前的日志
exit;

2、编写shell脚本
vi /home/oracle/delOracleLog/del_oracle_log.sh

#! /bin/bash
dt=`date +%Y%m%d`
rman target=/ cmdfile=/root/delOracleLog/del_ora_log.rman log=/root/delOracleLog/log/del_ora_log_${dt}.log  2>&1
4、测试脚本运行情况
[root@rac2 delOracleLog]# su - oracle -c /root/delOracleLog/del_oracle_log.sh 
RMAN> 2> 3> 4> [root@rac2 delOracleLog]# cat ./log/del_ora_log_20231124.log

exit;
4> 
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=2852 instance=orcl2 device type=DISK

5、设置定时任务每周执行一次,并测试运行效果

crontab -e
设置为每周五 9点25执行一次。【测试效果用实际情况建议夜间运行】:

25 9 * * 5 su - oracle -c /root/delOracleLog/del_oracle_log.sh

启动定时任务
service crond start

[root@rac2 delOracleLog]# pwd
/root/delOracleLog
[root@rac2 delOracleLog]# ll ./log/
总用量 4
-rw-r--r--. 1 oracle oinstall 621 1124 09:25 del_ora_log_20231124.log
[root@rac2 delOracleLog]# cat ./log/del_ora_log_20231124.log
