--//发现自己写的革除aud脚本通用性不好,每次都要批改,写一个通用脚本.而且一些服务器有多个实例的状况.
--//编写脚本如下:

cat /usr/local/bin/purge_oracle_aud.sh

! /bin/bash

purge oracle audit log

odebug=${ODEBUG:-0}

if (( $# < 1 ))
then

    echo "arguments is insufficiency , argumentN = oracle_sid N>=1"    exit  1

for i in "$@"
do

    if [ -d /u01/app/oracle/admin/${i}/adump/ ]    then            echo            echo "start purge oracle audit ${i} at : " $(/bin/date +'%Y/%m/%d %T')            /usr/bin/find /u01/app/oracle/admin/${i}/adump/ -mtime +30  -name "${i}_ora_*.aud" -print -delete            echo "end   purge oracle auditwww.cungun.com ${i} at : " $(/bin/date +'%Y/%m/%d %T')            echo    else            echo "/u01/app/oracle/admin/${i}/adump/ directory is not exist"            exit 2    fi

done

chmod 700 /usr/local/bin/purge_oracle_aud.sh

--//还是通用性不好,没有利用环境变量$ORACLE_BASE,先临时这样没工夫.

2.退出crontab页游脚本:

cat /etc/cron.d/ntp

34 6 * root /usr/local/bin/purge_oracle_aud.sh dbcndg2 >> /var/log/purge_oracle_aud.log 2>&1
--//每天6:34分执行.

3.批改/etc/logrotate.d/oracle,退出如下:

grep -v "^#" /etc/logrotate.d/oracle

/var/log/purge_oracle_aud.log
{

size=20Mrotate 5copytruncatecompressnotifemptymissingok

}
