Prioritizing processes by using sub-allocations.
Allocation or sub-allocation Properties.
Sub-allocations have precedence over the default resource allocation policy.
You can create as many sub-allocations as you need.
These sub-allocations are grouped hierarchically under the top-level resource allocation.
When this management rule is selected, sub-allocation is not allowed.
To create a sub-allocation in an existing resource allocation.
The following table gives an example of how you can prioritize processes by using sub-allocations.
For more information, see the sub-allocation section later in this topic.
Each sub-allocation must be configured to use a different process matching criterion.
For more information about sub-allocation, see Sub-Allocate Resources.
Sub-allocations are created in existing resource allocations, which are part of resource allocation policies.
One situation in which you would use sub-allocation is when you have a single server that performs multiple functions.
A sub-allocation allocates resources that are calculated as a percentage of the resources allocated by the parent resource allocation.
The following table gives an example of how you can use simple sub-allocation to divide resources within a resource allocation policy.
This sub-allocation matches a different process matching criterion than the parent resource allocation.
The only relationship between a resource allocation and its sub-allocation is that they share the CPU bandwidth allocated by the parent resource allocation.
A sub-allocation is a resource allocation hierarchy that consists of one or more grouped resource allocations.
If the same process matching criterion is used multiple times in a sub-allocation hierarchy, processes will be managed by the first resource allocation they match.
The sub-allocation that is last in the hierarchy is applied first, and the remaining allocations are applied in order moving back up the hierarchy to the parent resource allocation.
The percentage of the CPU that is allocated to the parent resource allocation is then distributed among the sub-allocations, following the proportions that are specified in the CPU allocation of each sub-allocation.
You can create more sub-allocations under the parent resource allocation by clicking Sub-allocate resources again.
When you are finished creating sub-allocations, on the parent resource allocation Properties page, click OK.
To create sub-allocations under a sub-allocation, click Sub-allocate resources, click the sub-allocation that you want to further sub-allocate, click Edit, and then continue from Step 3 of this procedure.
Each allocation or sub-allocation is listed in the order in which you would create it.
Because the sub-allocations in the example add up to 50 percent of the parent resource allocation, processes that match pmc_A can use a minimum of 25 percent of the total CPU bandwidth, or 50 percent of the 50 percent available to ra_A.
Each allocation or sub-allocation is listed in the order in which you would create it.
You can only create a sub-allocation when the management rule of the parent resource allocation is set to Standard.
Because the resources not used by a sub-allocation become available to its parent resource allocation,you can use this built-in logic to prioritize processes by using sub-allocations.
