【Oracle】AHF安装使用

一、工具简介

TFA ：收集日志的工具
ORAchk/EXAchk ： 检查系统的工具
AHF ：Oracle在2019年10月18日发布自治健康框架Autonomous Health Framework (AHF) 19.3，将ORAchk，EXAchk，TFA三种诊断工具合并入AHF，作为一个单一的安装软件被称作AHF。AHF可以使用root或者非root用户安装，而且所有的命令行指令和之前版本一样，ORAchk，EXAchk，TFA被放置在AHF_LOC/bin的目录下。----AHF需要定期更新。

二、安装

Installation Instructions
-------------------------
This must be completed for each node of a cluster.

1) Copy the zip file to a target machine and unzip
2) Run the command: ahf_setup

For advanced installation options see the User Guide

3、安装

注意：若是RAC，想同时检查两边节点，则需要先配置两节点root的互信，然后在节点1安装AHF时会提示在节点2自动安装。若root未互信成功，则不能在节点2正常安装。

[root@rhel75 ~]# ./ahf_setup

三、AHF使用

（1）用root执行orachk，后面会提示操作。

（2）若仅安装了GI或GI和DB，未创建实例，则需使用如下 -nordbms，否则无法执行成功。
