前言:公司搭建了DataGuard,刚开始没有注意备库归档日志的管理,,系统运行了一段时间之后,发现备库的空间被归档日志给撑爆了。

解决思路:Oracle提供了一个视图可以查看归档日志的执行情况,只要归档日志已经被应用了,就可以通过操作系统进行删除。

查看归档日志的运用脚本:select sequence#,applied from v$archived_log order by sequence#;

以下是我配置的操作系统的定时删除脚本:

#!/bin/sh

export PATH

ORACLE_SID=orcl

TABLE='v$archived_log'

export ORACLE_BASE ORACLE_SID

export ORACLE_HOME=/u01/app/oracle/product/OraDb11g_home1

export PATH=$PATH:$ORACLE_HOME/bin:$ORACLE_HOME/OPatch

$ORACLE_HOME/bin/sqlplus -silent "/ as sysdba" /home/oracle/deleteorclarch.sh
 
set heading off;

set pagesize 0;

set term off;

set feedback off;

set linesize 32767;

select 'rm -rf '||name from ${TABLE}  where DELETED='NO' and APPLIED='YES';

exit;

EOF

sh /home/oracle/deleteorclarch.sh

rman target /

crosscheck archivelog all;

delete noprompt expired archivelog all;

exit;

END 

通过crontab每天定时运行脚本即可;
