每天定时检查Oracle alert日志并发送mail的shell脚本
每天早上8点检查从昨天16点到现在的alert日志信息并发送mail，每天16点检查从早上8点到现在的alert日志信息并发送mail。这样就持续起来就可以保持每天都可见检查alert日志信息。虽然不能实时监测到错误并发mail但是对日常点检来说足够了。相当于每天查看两次alert日志信息。
每天上午8点的shell脚本如下：

同样每天16点的shell脚本将相应的datet进行注释替换就好了。

#!/bin/bash

# Every day at 16:00 check today fom 8.00 to now alert log info dbabc.net

# by dbabc.net 2011/1/14 dbabc.net

# User specific environment and startup programs dbabc.net

datet=`date -d yesterday “+%a %b %d”`” 16″ ### yesterday 00:00

#datet=`date “+%a %b %d”`” 08″ ####today 8:00
