Abstract

In accordance with an embodiment, described herein is a system and method for providing a work manager for use in an application server environment. In accordance with an embodiment, a system administrator can configure a partition work manager to provide partition work request prioritization (fair share value) to each partition within a multitenant application server environment. The system administrator can additionally configure the partition work manager to impose a minimum threads constraint limit, a partition capacity constraint, and/or a partition maximum threads constraint, all of which restrict the use of thread resources by the partitions within the environment.

Claims

1. A system for providing a work manager for use in an application server environment, comprising:

one or more computers, including an application server environment executing thereon, together with

a plurality of deployable resources which can be used within the application server environment,

one or more partitions, wherein each partition provides an administrative and runtime subdivision of a domain;

a partition work manager configurable, by a system administrator, to assign a fair share value to each of the one or more partitions within the application server environment, each fair share value configured for use by the system to control thread usage associated with one or more partitions.

2. The system of claim 1, wherein the partition work manager is further configured to provide a minimum threads constraint value for each partition within the application server, the minimum threads constraint value configured for use by the system to control the thread usage associated with one or more partitions.

3. The system of claim 1, wherein the partition work manager is further configured to provide a partition capacity constraint value for each partition within the application server, the partition capacity constraint value configured for use by the system to limit a number of work requests from each partition.

4. The system of claim 1, wherein each of the fair share values assigned to the one or more partitions is a number between 1 and 99, with a sum of all the fair share values totaling 100.

5. The system of claim 1, wherein each of the fair share values is further configured for use by the system to, when a thread pool is fully occupied, order work requests from the respective partitions in a queue.

6. The system of claim 1, further comprising:

one or more partition-level work managers, each partition comprising one of the one or more partition-level work managers, wherein each of the one or more partition-level work managers is configurable to assign a partition fair share value to one or more applications executing within the respective partition, each partition fair share value configured for use by the system to control thread usage associated with the one or more applications executing within the respective partition.

7. The system of claim 6, wherein the each of the one or more partition-level work managers is a copy of the partition work manager, and wherein each of the one or more partition-level work managers is configurable by a partition administrator.

8. The system of claim 1, wherein the application server environment comprises a multi-tenant application server environment, and wherein the system can associate the one or more partitions with a tenant, for use by the tenant.

9. A method for providing a work manager for use in an application server environment, comprising:

providing, at one or more computers, including an application server environment executing thereon,

a plurality of deployable resources which can be used within the application server environment,

one or more partitions, wherein each partition provides an administrative and runtime subdivision of a domain;

providing a partition work manager, the partition work manager being configurable by a system administrator; and

configuring the partition work manager to assign a fair share value to each of the one or more partitions within the application server environment, each fair share value configured for use by the system to control thread usage associated with one or more partitions.

10. The method of claim 9, further comprising:

further configuring the partition work manager to provide a minimum threads constraint value for each partition within the application server environment, the minimum threads constraint value configured for use by the system to control the thread usage associated with one or more partitions.

11. The method of claim 9, further comprising:

further configuring the partition work manager to provide a partition capacity constraint value for each partition within the application server environment, the partition capacity constraint value configured for use by the system to limit a number of work requests from each partition.

12. The method of claim 9, wherein each of the fair share values assigned to the one or more partitions is a number between 1 and 99, with a sum of all the fair share values totaling 100.

13. The method of claim 9, further comprising:

further configuring the partition work manager to provide a partition maximum threads constraint for each partition within the application server environment, the partition maximum threads constraint configured for use by the system to control the thread usage associated with one or more partitions.

14. The method of claim 9, further comprising:

providing one or more partition-level work managers, each of the one or more partitions comprising one of the one or more partition-level work managers, and

configuring each of the one or more partition-level work managers to assign a partition fair share value to one or more applications executing within the respective partition, each partition fair share value configured for use by the system to control thread usage associated with the one or more applications executing within the respective partition.

15. The method of claim 14, wherein the each of the one or more partition-level work managers is a copy of the partition work manager, and wherein each of the one or more partition-level work managers is configurable by a partition administrator.

16. A non-transitory computer readable storage medium, including instructions stored thereon which when read and executed by one or more computers cause the one or more computers to perform the steps comprising:

providing, at one or more computers, including an application server environment executing thereon,

a plurality of deployable resources which can be used within the application server environment,

one or more partitions, wherein each partition provides an administrative and runtime subdivision of a domain;

providing a partition work manager, the partition work manager being configurable by a system administrator; and

configuring a partition work manager to assign a fair share value to each of the one or more partitions within the application server environment, each fair share value configured for use by the system to control thread usage associated with one or more partitions.

17. The non-transitory computer readable storage medium of claim 16, the steps further comprising:

further configuring the partition work manager to provide a minimum threads constraint value for each partition within the application server environment, the minimum threads constraint value configured for use by the system to control the thread usage associated with one or more partitions; and

further configuring the partition work manager to provide a partition capacity constraint value for each partition within the application server environment, the partition capacity constraint value configured for use by the system to limit a number of work requests from each partition.

18. The non-transitory computer readable storage medium of claim 16, wherein each of the fair share values assigned to the one or more partitions is a number between 1 and 99, with a sum of all the fair share values totaling 100.

19. The non-transitory computer readable storage medium of claim 16, wherein each of the fair share values is further configured for use by the system to, when a thread pool is fully occupied, order work requests from the respective partitions in a queue.

20. The non-transitory computer readable storage medium of claim 16, the one or more steps further comprising:

providing one or more partition-level work managers, each of the one or more partitions comprising one of the one or more partition-level work managers, and

configuring each of the one or more partition-level work managers to assign a partition fair share value to one or more applications executing within the respective partition, each partition fair share value configured for use by the system to control thread usage associated with the one or more applications executing within the respective partition.
