使用shell脚本实现对Oracle数据库的监控与管理将大大简化DBA的工作负担,如常见的对实例的监控,监听的监控,告警日志的监控,以及数据库的备份,AWR report的自动邮件等。本文给出Linux 下使用 shell 脚本来监控 Oracle 实例。
1、监控Oracle实例shell脚本

2、补充
a、上面的脚本根据/etc/oratab中列出的实例进行监控,可以监控多个实例。
b、变量X_DB用于排除那些不需要监控的实例,如脚本中排出了3个实例。也可以将该变量置空。
c、如果X_DB的值为空时,我们赋予了DUMMY,确保你的数据库实例名没有使用DUMMY,否则过滤不掉。
d、监控脚本在监控过程中只要有一个实例宕掉,则发送整个监控报告。
d、使用了sendEmail邮件发送程序来发送邮件。参阅:不可或缺的 sendEmail
e、尾部清除监控过程中产生的保留日期之前的日志。
