Supported CPU and Memory Reallocations

Language:

SuperCluster compute server CPU and memory resources are initially allocated during the installation. However, the amount of resources that are allocated to domains can be modified by Oracle personnel during the installation, or you can change the resources later using utilities provided in the SuperCluster software.

If you want to specify non-default resource allocations for the installation, enter your specifications in the Configuration Worksheets prior to the installation. See Specifying CPU and Memory Resources in Configuration Worksheets.

This table lists the supported resource allocation activities.

Domain Configuration	Supported Allocation Activities	Utility Used	For More Information
All domains are dedicated domains	Reallocate all of the resources across domains at the socket or core level (a reboot might be required if primary domain resources are changed).	`osc-setcoremem`	For `osc-setcoremem` instructions refer to:Configuring CPU and Memory Resources (osc-setcoremem) in the Oracle SuperCluster M8 and SuperCluster M7 Administration Guide
	Remove (park) resources from dedicated domains for licensing purposes.	`osc-setcoremem`
Mixed domains – some are dedicated, some are Root Domains	Before any I/O Domains are Created: Reallocate all of the resources across domains at the socket or core level (a reboot is required if primary domain resources are changed).	`osc-setcoremem`
	Anytime: Remove resources from dedicated domains so that the resources are available to I/O Domains.	`osc-setcoremem`
	Move resources between dedicated domains.	`osc-setcoremem`
	Configure resources for I/O Domains.	SuperCluster Virtual Assistant	Oracle I/O Domain Administration Guide

CPU and memory resources that have been released to CPU and memory repositories in support of I/O domains, cannot be unparked for use in dedicated domains
