Oracle数据库管理常用的监控脚本------极大的简化运维工作

　　

　　最近几天都研究SHELL脚本，为了方便对公司的Oracle运维，简化管理，学习一些SHELL脚本是非常有必要的，通过书本和网上的一些资料，整理出了一些比较精典的脚本，都是经过清自测试可行的，放上来共大家分享。

 

# 监控Oracle监听状态(chk_lsnr_stat.sh)
# ======================================================================================
# 监控Oracle监听器状态，发现状态异常启动监听，并发送邮件通知管理员，如果启动监听失败，发送邮件
# 通知管理员。
# ======================================================================================

   echo "" >> $tempfile

   echo "======================================================" >> $tempfile
