一、 前言
1、由于每月月底都需要对一些oracle数据库环境进行一些简单的巡检，而通过运行一条条语句，并依依去截图保存到word文档中效率低下，所以这里我就将手工巡检过程编写成shell脚本来提高巡检效率，同时也免去了截图照片图片不清晰的问题。
2、脚本简单容易二次编辑，本文仅提供简单巡检的事项，如数据表空间是否自动扩展、是否开启归档等，大家根据实际需要编辑修改，增加符合自己公司需求的巡检报告。
3、项目已经上传到我的github上
项目地址：orawatch.git
二、注意事项与报告部分截图
一定注意阅读git上的readme.md说明，避免 system 用户被锁定。
三、readme.md
1、需要使用oracle用户执行
2、使用说明
1)、多实例下运行此脚本：
声明实例名；执行时跟上此实例对应的 system 密码
$ export oracle_sid=orcl $ chmod +x orawatch.sh $ ./orawatch.sh system/yourpassword
或者是将此实例对应的 system 密码填写到脚本中，随后执行
$ vi orawatch.sh sqlstr="system/system" $ chmod +x orawatch.sh $ ./orawatch.sh
2)、请注意一定要将对应实例名的对应system密码填写至脚本如下位置，或是执行时跟上对应实例的system密码，否则将造成 system 用户因密码错误而被锁定
system用户解锁语句：
sql> alter user system account unlock; alter user system identified by yourpassword;
3、执行完巡检之后，将在脚本所在的路径下生成html巡检结果报告，如下
192.168.35.244os_oracle_summary.html
4、巡检项信息如下（其他统计项可根据实际需要自行添加）
0)、巡检ip信息
1)、数据库版本
2)、是否开启归档，及归档磁盘占用率与路径信息
3)、数据库memory/sga/pga信息
4)、数据表空间是否自动扩展
5)、数据库当前分配的数据表空间使用率信息
