项目中某个组件经常性出问题，重启下便好了。所以写个脚本每天跑一下重启组件。并且监控组件状态，如果启动失败，自动发送通知邮件到指定邮箱。
1. 在Linux系统上使用crontab 命令定时（循环）执行某个任务的程序
crontab -l //列出某个用户cron服务的详细内容
crontab filename //根据文本内容设定定时作业
这里我新建一个cron.txt , 内容为 01 2 * * * /home/oracle/cron/comp_sfs.sh
然后执行 crontab cron.txt，任务会被自动加载，因为Cron服务会每隔一分钟Check所有的任务。
2. 编写重启脚本 comp_sfs.sh
Siebel 提供了服务器组件、任务、会话管理命令行接口，（Siebel Component Manage Command Line Interface），并提供了 /b 等批处理参数，执行批处理时可以将输入的命令全部保存到文件，从文件加载命令，如果要使用awk获取命令执行后返回的组件状态，则必须定制返回结果的显示列，使用 configure list comp show column1,column2,column3,……，这里我只定制输出了当前运行的用户数，运行状态，组件别名等不包含空格的列（awk输出是用空格做分隔符）。捕获状态后根据状态值确定组件是否正常，正常启动的状态应该为 Online 或 “在线”，如是其他状态则发送通知邮件。

linux本身是支持发送邮件的，有相关命令，但前面我写过一个python 发送邮件的脚本，就用现成的了。
