Oracle运维脚本

前端之家收集整理的这篇文章主要介绍了Oracle运维脚本前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

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
