Abstract

In accordance with an embodiment, described herein is a system and method for providing a partition file system in a multitenant application server environment. The system enables application server components to work with partition-specific files for a given partition, instead of or in addition to domain-wide counterpart files. The system also allows the location of some or all of a partition-specific storage to be specified by higher levels of the software stack. In accordance with an embodiment, also described herein is a system and method for resource overriding in a multitenant application server environment, which provides a means for administrators to customize, at a resource group level, resources that are defined in a resource group template referenced by a partition, and to override resource definitions for particular partitions.

Claims

1. A system for supporting partition file systems in a multitenant application server environment, comprising:

one or more computers, including one or more processors, and an application server environment executing thereon;

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

one or more resource group templates, which define groupings of the deployable resources within a domain, wherein each resource group template defines, at the domain level, a collection of the deployable resources that are referenceable from a resource group; and

one or more partitions,

wherein each particular partition, of the one or more partitions, provides a subdivision of the domain, that can be associated with a tenant, and

wherein the particular partition includes one or more resource groups; and

wherein the system associates the particular partition with a partition file system for use by the particular partition.

2. The system of claim 1, comprising a plurality of partitions, wherein each partition of the plurality of partitions is associated with its own partition file system, for use by that partition.

3. The system of claim 1, wherein the location of some or all partition file systems are specified by higher levels in the software stack.

4. The system of claim 1, wherein the application server environment is provided as part of a cloud environment, and supports multiple tenants within the cloud environment.

5. The system of claim 1, wherein each partition file system maps to physical storage and provides access to partition-specific files.

6. The system of claim 1, wherein each partition file system is associated with a lifecycle.

7. The system of claim 6, whereupon a new partition being created, the application server environment determines if an existing partition file system is available for use by the new partition, and if not creates a partition for use by the new partition.

8. A method for supporting partition file systems in a multitenant 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 resource group templates, which define groupings of the deployable resources within a domain, wherein each resource group template defines, at the domain level, a collection of the deployable resources that are referenceable from a resource group, and

one or more partitions,

wherein each particular partition, of the one or more partitions, provides a subdivision of the domain, that can be associated with a tenant,

wherein the particular partition includes one or more resource groups; and

associating, with the particular partition, a partition file system, for use by the particular partition.

9. The method of claim 8, comprising a plurality of partitions, wherein each partition of the plurality of partitions is associated with its own partition file system, for use by that partition.

10. The method of claim 8, wherein the location of some or all partition file systems are specified by higher levels in the software stack.

11. The method of claim 8, wherein the application server environment is provided as part of a cloud environment, and supports multiple tenants within the cloud environment.

12. The method of claim 8, wherein each partition file system maps to physical storage and provides access to partition-specific files.

13. The method of claim 8, wherein each partition file system is associated with a lifecycle.

14. The method of claim 13, whereupon a new partition being created, the application server environment determines if an existing partition file system is available for use by the new partition, and if not creates a partition for use by the new partition.

15. 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 an application server environment, together with

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

one or more resource group templates, which define groupings of the deployable resources within a domain, wherein each resource group template defines, at the domain level, a collection of the deployable resources that are referenceable from a resource group, and

one or more partitions,

wherein each particular partition, of the one or more partitions, provides a subdivision of the domain, that can be associated with a tenant,

wherein the particular partition includes one or more resource groups; and

associating, with the particular partition, a partition file system, for use by the particular partition.

16. The non-transitory computer-readable storage medium of claim 15, comprising a plurality of partitions, wherein each partition of the plurality of partitions is associated with its own partition file system, for use by that partition.

17. The non-transitory computer-readable storage medium of claim 15, wherein the location of some or all partition file systems are specified by higher levels in the software stack.

18. The non-transitory computer-readable storage medium of claim 15, wherein the application server environment is provided as part of a cloud environment, and supports multiple tenants within the cloud environment.

19. The non-transitory computer-readable storage medium of claim 15, wherein each partition file system is associated with a lifecycle.

20. The non-transitory computer-readable storage medium of claim 15, wherein each partition file system maps to physical storage and provides access to partition-specific files.
