[ORACLE] Increasing the number of cores in a virtualized Oracle Database Appliance.

Hello everyone.

How are you going?

Today, I'll show you the process to increase the number of cores in a virtualized ODA HA X7-2.

Important: This process must be validated with Oracle Support, always.

 

Furthermore, remember that:  

• This step-by-step worked for me, but it may not work for you. 
• It's a test environment. The real life will be different, for sure.
• This post is for study and testing as well and has no concern for performance and security best practices.

So, let's get started!

 

The first step is create a new BIOS xml file to change the number of the cores.

su -

ubiosconfig export all -x bios.xml

We need to change te parameter below:

vi bios.xml

From: <Active_Processor_Cores>3</Active_Processor_Cores>

To:      <Active_Processor_Cores>4</Active_Processor_Cores>

In my example, I'll change to 3 cores for 4 cores.

Now, we need to import the new parameter.

su - 

ubiosconfig import config -f --expert -y -x bios.xml

Reboot the node and we have 4 cores on node 1. Repeat the process for node 2.

After:

After this, it was easy!

odacli update-cpucore --cores 8

{

  "jobId" : "388ac288-abaf-4304-8a3b-b033e4ca7dde",

  "status" : "Created",

  "message" : null,

  "reports" : [ ],

  "createTimestamp" : "July 11, 2024 02:49:22 AM BRT",

  "resourceList" : [ ],

  "description" : "CPU cores  service update",

  "updatedTime" : "July 11, 2024 02:49:22 AM BRT"

}

And, there you go!

I hope it helps!
