This section describes how to set the CPU core count on Oracle Database Appliance X3-2 bare metal deployments.
Complete the following procedure to set the CPU core count:
- Log in to My Oracle Support.
- Click the Settings tab, and select Assets from the submenu.
- Search for the serial number of the appliance in the asset list. If you cannot locate the serial number, then contact Oracle Support.
- Select the serial number of the appliance.
- Select Manage Key from the available actions.
- In the Manage Cores Configuration Key dialog, you can view the serial number of the appliance. If there is a previously generated key, then you can view the current configuration.
- In the Cores Per Server list, select the number of enabled CPU cores that you want to configure for each server. The value you select will apply to both servers on the appliance. Initially, you can select 4, 8, 12, or 16. Subsequently, you can only select a number that is greater than the current number.
- Click Generate Key to generate the key.
- Click Copy Key to Clipboard to copy the key to the clipboard.
- Paste the key into an empty text file, and save the file to a location on Oracle Database Appliance.
- Log in to one of the servers on Oracle Database Appliance as
root.
- Run the following command to restart the server to complete the reconfiguration, where key_file_location is the full path name of the text file that you created in Step 7:
/opt/oracle/oak/bin/oakcli apply core_configuration_key key_file_location
For example:
/opt/oracle/oak/bin/oakcli apply core_configuration_key /home/myfile.txt
After the system restarts, Oracle Database Appliance is reconfigured, and both servers to run with the specified CPU core count. Always assign cores to Oracle Database Appliance X3-2 bare metal deployments in multiples of four, with a minimum of four cores.
