Shared resource management
View Patent ↗Systems, methods, apparatus, and computer program products are provided for monitoring and allocating shared resources. For example, in one embodiment, the status of resource dependent entities is continuously monitored to determine the current use of a shared resource. When a resource dependent entity requires use of the shared resource, a (a) request for use of the shared resource can be generated and (b) determination can be made as to whether any of the current allocations of the shared resource can be released for use by the resource dependent entity.
1. A computer-implemented method for monitoring a shared resource, the computer-implemented method comprising:
monitoring, via one or more processors, use of a shared resource by a first resource dependent entity, wherein the first resource dependent entity (a) is associated with a resource dependent entity identifier and (b) is associated with a relationship status that identifies the first resource dependent entity's use of the shared resource;
after a change in use of the shared resource by the first resource dependent entity, generating a notification of the change in use;
after receiving the notification of the change in use of the shared resource by the first resource dependent entity, updating the relationship status of the first resource dependent entity to reflect the change in use by the first resource dependent entity;
receiving, via the one or more processors, a request from a second resource dependent entity for use of the shared resource;
after receiving the request from the second resource dependent entity for use of the shared resource, determining whether the shared resource is available to satisfy the request of the second resource dependent entity, wherein the determination is based at least in part on the relationship status of the first resource dependent entity;
after a determination that the shared resource is not available to satisfy the request of the second resource dependent entity, determining whether at least a portion of the shared resource can be released from the first resource dependent entity to satisfy the request of the second resource dependent entity; and
after a determination that the at least a portion of the shared resource can be released from the first resource dependent entity, causing release of the at least a portion of the shared resource from the first resource dependent entity and generating a notification indicating the availability of the shared resource for the second resource dependent entity;
wherein (a) the relationship status is selected from the group consisting of a strongly owned relationship, a weakly owned relationship, and an unowned relationship and (b) the relationship status changes during the lifetime of the first resource dependent entity; and
wherein the first resource dependent entity's use of the shared resource is released prior to the termination of normal processing and allocated to the second resource dependent entity.
2. The computer-implemented method of claim 1 , wherein determining whether the at least the portion of the shared resource can be released from the first resource dependent entity comprises determining whether the relationship status of the first resource dependent entity to the shared resource is associated with a weakly owned relationship status.
3. The computer-implemented method of claim 1 , wherein the shared resource is selected from the group consisting of (a) one or more memory storage areas and (b) one or more connections to a computing entity.
4. A computer program product for monitoring a shared resource, the computer program product comprising at least one non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:
an executable portion configured to monitor use of a shared resource by a first resource dependent entity, wherein the first resource dependent entity (a) is associated with a resource dependent entity identifier and (b) is associated with a relationship status that identifies the first resource dependent entity's use of the shared resource;
an executable portion configured to, after a change in use of the shared resource by the first resource dependent entity, generate a notification of the change in use;
an executable portion configured to, after receiving the notification of the change in use of the shared resource by the first resource dependent entity, update the relationship status of the first resource dependent entity to reflect the change in use by the first resource dependent entity;
an executable portion configured to receive a request from a second resource dependent entity for use of the shared resource;
an executable portion configured to, after receiving the request from the second resource dependent entity for use of the shared resource, determine whether the shared resource is available to satisfy the request of the second resource dependent entity, wherein the determination is based at least in part on the relationship status of the first resource dependent entity;
an executable portion configured to, after a determination that the shared resource is not available to satisfy the request of the second resource dependent entity, determine whether at least a portion of the shared resource can be released from the first resource dependent entity to satisfy the request of the second resource dependent entity; and
an executable portion configured to, after a determination that the at least a portion of the shared resource can be released from the first resource dependent entity, cause release of the at least a portion of the shared resource from the first resource dependent entity and generate a notification indicating the availability of the shared resource for the second resource dependent entity;
wherein (a) the relationship status is selected from the group consisting of a strongly owned relationship, a weakly owned relationship, and an unowned relationship and (b) the relationship status changes during the lifetime of the first resource dependent entity; and
wherein the first resource dependent entity's use of the shared resource is released prior to the termination of normal processing and allocated to the second resource dependent entity.
5. The computer program product of claim 4 , wherein determining whether the at least the portion of the shared resource can be released from the first resource dependent entity comprises determining whether the relationship status of the first resource dependent entity to the shared resource is associated with a weakly owned relationship status.
6. The computer program product of claim 4 , wherein the shared resource is selected from the group consisting of (a) one or more memory storage areas and (b) one or more connections to a computing entity.
7. An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the processor, cause the apparatus to at least:
monitor use of a shared resource by a first resource dependent entity, wherein the first resource dependent entity (a) is associated with a resource dependent entity identifier and (b) is associated with a relationship status that identifies the first resource dependent entity's use of the shared resource;
after a change in use of the shared resource by the first resource dependent entity, generate a notification of the change in use;
after receiving the notification of the change in use of the shared resource by the first resource dependent entity, update the relationship status of the first resource dependent entity to reflect the change in use by the first resource dependent entity;
receive a request from a second resource dependent entity for use of the shared resource;
after receiving the request from the second resource dependent entity for use of the shared resource, determine whether the shared resource is available to satisfy the request of the second resource dependent entity, wherein the determination is based at least in part on the relationship status of the first resource dependent entity;
after a determination that the shared resource is not available to satisfy the request of the second resource dependent entity, determine whether at least a portion of the shared resource can be released from the first resource dependent entity to satisfy the request of the second resource dependent entity; and
after a determination that the at least a portion of the shared resource can be released from the first resource dependent entity, cause release of the at least a portion of the shared resource from the first resource dependent entity and generate a notification indicating the availability of the shared resource for the second resource dependent entity;
wherein (a) the relationship status is selected from the group consisting of a strongly owned relationship, a weakly owned relationship, and an unowned relationship and (b) the relationship status changes during the lifetime of the first resource dependent entity; and
wherein the first resource dependent entity's use of the shared resource is released prior to the termination of normal processing and allocated to the second resource dependent entity.
8. The apparatus of claim 7 , wherein determining whether the at least the portion of the shared resource can be released from the first resource dependent entity comprises determining whether the relationship status of the first resource dependent entity to the shared resource is associated with a weakly owned relationship status.
9. The apparatus of claim 7 , wherein the shared resource is selected from the group consisting of (a) one or more memory storage areas and (b) one or more connections to a computing entity.
