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 resource overriding in a multitenant application server environment, comprising:

one or more computers, including an application server environment that enables deployment and execution of software applications, wherein the application server environment includes;

a domain configuration that defines an application server domain for execution of the software applications, and a plurality of partitions of the domain;

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

one or more resource groups that enable partition-specific information to be provided for one or more of the resources;

wherein each partition of the plurality of partitions, is associated with a partition configuration, and provides a subdivision of the domain, and includes one or more of the resource groups; and

wherein each particular partition of the plurality of partitions can be associated with at least one of a partition-specific resource configuration information or application deployment plan that enables the application server environment to configure resource overrides for the particular partition, to customize, at the resource group level, the one or more resources to be used with the particular partition, and to configure an application for deployment to the particular partition.

2. The system of claim 1, wherein the system enables use of at least one of application deployment plans or resource deployment plans, to configure the resource overrides for use with a partition.

3. The system of claim 2, wherein an application deployment plan overwrites an application deployment descriptor, including that different application deployment plans can be specified for different applications executing in different partitions.

4. The system of claim 2, wherein a resource deployment plan creates resource overrides for use with a particular resource group template in customizing resources defined by the particular resource group template, for use with a partition.

5. The system of claim 1, wherein the system enables use of overriding config beans to override resource definitions for use with a partition.

6. The system of claim 1, wherein some or all of the resource overrides are specified by upper levels in the software stack.

7. The system of claim 1, wherein each particular partition of the plurality of partitions is associated with an application deployment plan that enables the application server environment to configure the application for deployment to the particular partition in accordance with the application deployment plan for that partition.

8. A method for resource overriding in a multitenant application server environment, comprising:

providing, at one or more computers, an application server environment that enables deployment and execution of software applications, wherein the application server environment includes;

a domain configuration that defines an application server domain for execution of the software applications, and a plurality of partitions of the domain;

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

one or more resource groups that enable partition-specific information to be provided for one or more of the resources;

wherein each partition of the plurality of partitions, is associated with a partition configuration, and provides a subdivision of the domain, and includes one or more of the resource groups; and

associating each particular partition of the plurality of partitions with at least one of a partition-specific resource configuration information or application deployment plan that enables the application server environment to configure resource overrides for the particular partition, to customize, at the resource group level, the one or more resources to be used with the particular partition, and to configure an application for deployment to the particular partition.

9. The method of claim 8, further enabling use of at least one of application deployment plans or resource deployment plans, to configure the resource overrides for use with a partition.

10. The method of claim 9, wherein an application deployment plan overwrites an application deployment descriptor, including that different application deployment plans can be specified for different applications executing in different partitions.

11. The method of claim 9, wherein a resource deployment plan creates resource overrides for use with a particular resource group template in customizing resources defined by the particular resource group template, for use with a partition.

12. The method of claim 8, further enabling use of overriding config beans to override resource definitions for use with a partition.

13. The method of claim 8, wherein some or all of the resource overrides are specified by upper levels in the software stack.

14. The method of claim 8, wherein each particular partition of the plurality of partitions is associated with an application deployment plan that enables the application server environment to configure the application for deployment to the particular partition in accordance with the application deployment plan for that 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 that enables deployment and execution of software applications, wherein the application server environment includes;

a domain configuration that defines an application server domain for execution of the software applications, and a plurality of partitions of the domain;

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

one or more resource groups that enable partition-specific information to be provided for one or more of the resources;

wherein each partition of the plurality of partitions, is associated with a partition configuration, and provides a subdivision of the domain, and includes one or more of the resource groups; and

associating each particular partition of the plurality of partitions with at least one of a partition-specific resource configuration information or application deployment plan that enables the application server environment to configure resource overrides for the particular partition, input to customize, at the resource group level, the one or more resources to be used with the particular partition, and to configure an application for deployment to the particular partition.

16. The non-transitory computer readable storage medium of claim 15, further enabling use of at least one of application deployment plans or resource deployment plans, to configure the resource overrides for use with a partition.

17. The non-transitory computer readable storage medium of claim 16, wherein an application deployment plan overwrites an application deployment descriptor, including that different application deployment plans can be specified for different applications executing in different partitions.

18. The non-transitory computer readable storage medium of claim 16, wherein a resource deployment plan creates resource overrides for use with a particular resource group template in customizing resources defined by the particular resource group template, for use with a partition.

19. The non-transitory computer readable storage medium of claim 15, further enabling use of overriding config beans to override resource definitions for use with a partition.

20. The non-transitory computer readable storage medium of claim 15, wherein some or all of the resource overrides are specified by upper levels in the software stack.
