Solution 2220572.1 : ODA: X6-2 Capacity-On-Demand : How To Change & Register CPU Cores For Single-Node ODA Lite X6-2(S,M,L) or the Dual-Node ODA HA X6-2

Applies to:

Oracle Database Appliance X6-2 Hardware - Version All Versions to All Versions [Release All Releases]
Oracle Database Appliance - Version All Versions to All Versions [Release All Releases]
Information in this document applies to any platform.

Goal

How to change & register the core count for X6-2X ODA platform?

ODA Lite (Single-Node Servers) X6-2S, X6-2M, X6-2L
ODA HA (The original Two-node Servers) X6-2 HA

Revision 8/30 - Clarified After the initial configuration, you cannot reduce the number of cores.
Added Docset explicit example for 12.1.2.11 ODA X6-2 HA

Solution

ODA-Lite X6-2 S/M/L

(Single node servers) Using the odacli command

1 - In X6-2S X6-2M and X6-2L aka "ODA Lite", you can change core count using the command below:

odacli list-cores -- for the current core count (plus available

oda describe-core -- for available and current core count

odacli update-cpucore -c ## -- e.g. odacli update-cpucore -c 4

-> creates a job to update the Cores

oda list-jobs -- will confirm recent jobs including completion

Last, to confirm changes

odacli list-cores

COMMENT: There is no need to register the number of core count in My Oracle Support (MOS) in X6-2 HA or the ODA LITE Platform.

Please, read below:

Capacity-On-Demand Core configuration has changed as of the ODA X6-2 series

- Oracle LMS (Licensing) has a way to see if the customer is compliant with the licensing by running a command in the system. It will show us the history of the cores usage in the system.

- The mechanism of registering the number of cores is different in X6-2S X6-2M and X6-2L aka "ODA Lite" as well as the ODA X6-2 HA ( the original ODA two-server configuration)
In the past, we used to tell the customer to go ahead and register the number of cores in MOS by getting license key.
This is not required or the case anymore in ODA X6-2 HA or X6-2S X6-2M and X6-2L aka "ODA Lite".

As long as the ODA admin is changing/using the cores within the licensing purchase that already made from Oracle, then there is no issue or need for registering or letting Oracle know because as mentioned in point #1 LMS (Oracle Licensing) has a method to confirm that. For example, let's say a customer bought licensing to use 10 cores in ODA, if the customer decide to use only 4, then that's fine because the customer already paid for 10. The ODA Admin can grow the number of cores anytime as long as it does not increase 10 cores which is the number of license cores the customer bought from Oracle.

- The number of cores here is 'use it or lose it'. So if a customer bought 10 cores and use only 4 cores, then they are not using the rest of the 6 cores. It is the customer choice. However, Oracle won't reimburse or pay back the license cost.

After the initial configuration, you cannot reduce the number of cores.

ODA X6-2 HA

(The original Two node server configuration) Using the oakcli command

From the Docset

Usage Notes

This command applies only to bare metal deployments.
The number of licensed cores you enable must be a multiple of 2, up to the maximum number of cores.
After the initial configuration, you cannot reduce the number of cores.
You can purchase additional cores and increase the number of cores, up to the maximum number of cores.
For example, up to the maximum of 20 cores for Oracle Database Appliance X6-2-HA.

Example 10-61 Enabling 12 CPU Cores for Oracle Database Appliance

The following command enables 12 CPU cores on an Oracle Database Appliance system.

oakcli update-cpucore -cores 12

Please enter the 'root' password: 
Please re-enter the 'root' password: 
Setting up SSH ..............Completed
INFO   : Running as root: /usr/bin/ssh -l root 192.0.2.1 /etc/rc.d/rc3.d/S90cpu-core
INFO   : Running as root: /usr/bin/ssh -l root 192.0.2.1 /etc/rc.d/rc3.d/S90cpu-core

Example 10-62 Enabling All CPU Cores for Oracle Database Appliance

The following command enables all cores on an Oracle Database Appliance system.

oakcli update-cpucore -cores All

Please enter the 'root' password: 
Please re-enter the 'root' password: 
Setting up SSH ..............Completed
INFO   : Running as root: /usr/bin/ssh -l root 192.0.2.1 /etc/rc.d/rc3.d/S90cpu-core
INFO   : Running as root: /usr/bin/ssh -l root 192.0.2.1 /etc/rc.d/rc3.d/S90cpu-core

Use the oakcli describe-cpucore command to confirm the Core Count

oakcli describe-cpucore

============================================
Enabled Cores (per server)                = #              e.g. 20
Total Enabled Cores (two servers)      = # times 2      e.g. 40
Server Type                                      =    e.g. X6-2 -> Oracle Server X6-2

Hyperthreading is enabled. Each core has 2 threads
Operating system displays 40 processors per server.
