Anticipatory resource allocation/activation and lazy de-allocation/deactivation
First Claim
1. A computer program product for managing resources in a server environment, the computer program product comprising:
- one or more computer readable tangible storage media and program instructions stored on at least one of the one or more storage media, the program instructions comprising;
program instructions to determine to deactivate a first resource consumer, wherein a first virtual resource with a first set of one or more host resources remains assigned to the deactivated first resource, wherein the first set of one or more host resources of the first resource consumer includes at least host resources that are not active and do not have host resource reserves;
program instructions to determine if a second virtual resource assigned to a second resource consumer requires the first set of one or more host resources;
program instructions to, responsive to determining the second virtual resource assigned to the second resource consumer does not require the first set of one or more host resources, determine not to deactivate the one or more host resources assigned to the first virtual resource;
program instructions to determine a second set of one or more host resources is required to satisfy a third resource consumer; and
program instructions to, responsive to determining the second set of one or more host resources is available, determine to utilize the first set of one or more host resources of the first resource consumer for the required second set of one or more host resources.

Abstract
A computer-implemented method, carried out by one or more processors, for managing resources in a server environment. The method includes determining, by one or more processors, to shut down a first resource consumer, wherein the first resource consumer is assigned a first virtual resource with a first set of one or more host resources. It is determined, by one or more processors, whether a second virtual resource assigned to a second resource consumer requires the first set of one or more host resources. If the second virtual resource assigned to the second resource consumer does not require the first set of one or more host resources, it is determined, by one or more processors, not to deactivate the one or more host resources assigned to the first virtual resource.

6. A computer system for managing resources in a server environment, the computer system comprising:
-
one or more computer processors; one or more computer readable storage media; and program instructions stored on the computer readable storage media for execution by at least one of the one or more computer processors, the program instructions comprising; program instructions to determine to deactivate a first resource consumer, wherein a first virtual resource with a first set of one or more host resources remains assigned to the deactivated first resource, wherein the first set of one or more host resources of the first resource consumer includes at least host resources that are not active and do not have host resource reserves; program instructions to determine if a second virtual resource assigned to a second resource consumer requires the first set of one or more host resources; program instructions to, responsive to determining the second virtual resource assigned to the second resource consumer does not require the first set of one or more host resources, determine not to deactivate the one or more host resources assigned to the first virtual resources; program instructions to determine a second set of one or more host resources is required to satisfy a third resource consumer; and program instructions to, responsive to determining the second set of one or more host resources is available, determine to utilize the first set of one or more host resources of the first resource consumer for the required second set of one or more host resources. - View Dependent Claims (7, 8, 9, 10)
