Goal

How To Increase CPU Count On ODA X6-2

Capacity on Demand

Solution

There are two types of ODA X6-2 servers:

X6-2 HA (ODA High availability = 2 servers per ODA)
X6-2 S/M/L (X6-2 Small, X6-2 Medium, X6-2 Large = All single servers )

Regardless of the X6-2 ODA you have, there is a new procedure for the generation of Core Keys for "Capacity on Demand"
After the initial Core Key configuration for ODA, core key generation can only be increased, not decreased.*
The ODA X6-2 does not use MOS for the Core key generation.

* True for all ODA models and releases

X6-2 HA

Virtualized ODA HA X6-2 does not enable or use Core Keys
To update the Core Count on the Bare Metal X6-2 HA use the oakcli command line interface

oakcli update-cpucore -cores <core_count> This command generates the number of cores per server [-h]

Use the oakcli update-cpucore command to enable the number of CPU cores PER SERVER .

File Path /opt/oracle/oak/bin/oakcli

Syntax oakcli update-cpucore -cores number of cores per server [-h]

Example oakcli update-cpucore -cores 10 ( Generates total 20 for both servers of the ODA-HA SYSTEM = 10 per server)

Syntax oakcli describe-cpucore [-h]

Syntax oakcli list-cpucores [-h]

X6-2S X6-2M X6-2L

To update the Core Count use the odacli command line interface

odacli update-cpucore -c <core_count>

Use the odacli update-cpucore command to enable the number of CPU cores in the system.

File Path /opt/oracle/dcs/bin/odacli

Syntax odacli update-cpucore -c <##> [-h]

Example odacli update-cpucore -c 8

==============================================

From the ODA X6-2HA DOCSET available at DOCS.ORACLE.COM

==============================================

Use the oakcli update-cpucore command to enable a specified number of licensed CPU cores for Oracle Database Appliance X6-2-HA.

Prerequisites

If all cores are not enabled, you can enable multiples of 2 licensed CPU cores up to the maximum number of cores.

File Path

$ORACLE_HOME/opt/oracle/oak/bin/oakcli

Syntax

oakcli update-cpucore -cores number of cores per server [-h]

Parameters

Parameter Description

-cores

Defines the number of cores to enable per server, in multiples of 2.
To enable all available cores, specify "All" instead of the number of cores.

(Optional) Display help for using the command.

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 9-51 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

* TESTING Core Counts
=========

For testing and implementation purposes you are able to generate Core Keys below your target Core count.
This increasing core count strategy might be used when determining the minimum number of Cores required for load and business requirements.

For example: The following hypothetical example is regarding a user with 16 Core License

Option 1
-----------
Generate the key directly using 8 cores per server = 16 total for both nodes of the ODA-HA

Option 2
-----------
Generate a key for 4 per server (8 total for the ODA-HA)
Then generate the core key for 8 per server ( results in 16 total for the ODA System)

Option 3 - Increments of two increasing from minimum to targeted amount
------------
Generate keys for
- 2 per server (4 total)
Then
- 4 per server (8 total)
Then
- 6 per server ( 12 total )
Then
- 8 per server ( 16)
