[ORACLE] How do I install the Oracle Autonomous Health Framework (AHF)?

Hello everyone!!!

I hope you're doing well!

Today, I'll show you how to install the Oracle Autonomous Health Framework (AHF). 

I don't have an Oracle RAC installed here on my laptop, but I'll provide it. Today I'll show you a single-node environment.

I decided to write and learn a bit more about AHF after having the privilege of attending Sandesh Rao's live session at Oracle Cloudworld 2023 in Las Vegas.

First, what is Oracle Autonomous Health Framework?

In Oracle's words, it's a "Machine learning-based solution for maintaining database availability and performance".

In Mario's words, it's a "very cool tool that collects and groups your system health information and logs and uses Machine Learning to provide you insights and predictions so that you can act preventively, avoiding problems in your environment".



For more information, feel free to click.

So, let's get started!!!

But always remember:

  1. This step-by-step worked for me, but it may not work for you.
  2. It's a basic and limited environment. The real life will be different, for sure.
  3. This post is for study and testing as well, and has no concern for performance and security best practices.
1) Download the AHF zip file

In my post, I'll download version "AHF 23.7.0 for Linux". 

Calm down, calm down, buddy!!! I know we already have version 23.8 at the time of writing this post (Sep/23), but I'll show you how to upgrade the version on next post. 




2) Unzip the zip file

Important: I'll execute all installation with user ROOT.

[root@Mariao ~]# cd /u01/AHF
[root@Mariao ~]# unzip AHF-LINUX-v23.7.0.zip


3) Create the data directory.

[root@Mariao ~]# mkdir -p /AHF/Data


3) Run install.

In red, my changes and interactions.

[root@Mariao ~]# cd /u01/AHF/

[root@Mariao AHF]# ./ahf_setup
