Abstract

In accordance with an embodiment, the system supports use of an in-memory data grid or other distributed memory environment, for example Oracle Coherence. A partition provides a runtime and administrative subdivision or slice of an application server domain. An application can be deployed to a particular partition, or otherwise associated with a particular domain partition name. The domain partition name can be used by the data grid to enable a separation of data between different partitions or between tenants associated with those partitions. In some embodiments, one or more data grid services, for example caches and clustered services, can be shared across multiple partitions. Alternatively, the data grid can provide read-shared/write-specific access to data grid services, in which multiple partitions can share an initial set of data, but their subsequent modifications to that data are then isolated from each other.

Claims

1. A system for supporting partitions in an application server environment, comprising:

one or more computers, including an application server environment having a domain for execution of software applications, and one or more partitions, wherein each partition provides an administrative and runtime subdivision of the domain; and

an in-memory data grid, which supports separation of data used by different partitions from each other, including that

when a tenant-aware application is deployed to a particular partition, or is otherwise associated with a particular partition, a domain partition name is included in the application'"'"'s execution context, and is used by the data grid in creating one or more data grid resources and services, for use by the deployed application.

2. The system of claim 1, wherein the system can optionally associate a partition with a tenant, for use by the tenant.

3. The system of claim 1, wherein data grid resources and services are shared across multiple partitions.

4. The system of claim 1, wherein the data provides read-shared/write-specific access to data grid services, in which multiple partitions can share an initial set of data, but their subsequent modifications to that data are then isolated from each other.

5. The system of claim 1, wherein the system is provided within a cloud environment, to support multiple tenants operating within the cloud environment.

6. A method for supporting partitions in an application server environment, comprising:

providing, at one or more computers, an application server environment having a domain for execution of software applications, and one or more partitions, wherein each partition provides an administrative and runtime subdivision of the domain;

providing an in-memory data grid, which supports separation of data used by different partitions from each other; and

upon a tenant-aware application being deployed to a particular partition, or otherwise associated with a particular partition, including a domain partition name in the application'"'"'s execution context, for use by the data grid in creating one or more data grid resources and services, for use by the deployed application.

7. The method of claim 6, further optionally associating a partition with a tenant, for use by the tenant.

8. The method of claim 6, wherein data grid resources and services are shared across multiple partitions.

9. The method of claim 6, wherein the data grid provides read-shared/write-specific access to data grid services, in which multiple partitions can share an initial set of data, but their subsequent modifications to that data are then isolated from each other.

10. The method of claim 6, wherein the method is provided within a cloud environment, to support multiple tenants operating within the cloud environment.

11. 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 having a domain for execution of software applications, and one or more partitions, wherein each partition provides an administrative and runtime subdivision of the domain;

providing an in-memory data grid, which supports separation of data used by different partitions from each other; and

upon a tenant-aware application being deployed to a particular partition, or otherwise associated with a particular partition, including a domain partition name in the application'"'"'s execution context, for use by the data grid in creating one or more data grid resources and services, for use by the deployed application.

12. The non-transitory computer readable storage medium of claim 11, further optionally associating a partition with a tenant, for use by the tenant.

13. The non-transitory computer readable storage medium of claim 11, wherein data grid resources and services are shared across multiple partitions.

14. The non-transitory computer readable storage medium of claim 11, wherein the data grid provides read-shared/write-specific access to data grid services, in which multiple partitions can share an initial set of data, but their subsequent modifications to that data are then isolated from each other.

15. The non-transitory computer readable storage medium of claim 11, wherein the method is provided within a cloud environment, to support multiple tenants operating within the cloud environment.
