Abstract

In accordance with an embodiment, described herein is a system and method for supporting partitions in a multitenant application server environment. In accordance with an embodiment, an application server administrator (e.g., a WLS administrator) can create or delete partitions; while a partition administrator can administer various aspects of a partition, for example create resource groups, deploy applications to a specific partition, and reference specific realms for a partition. Resource groups can be globally defined at the domain, or can be specific to a partition. Applications can be deployed to a resource group template at the domain level, or to a resource group scoped to a partition or scoped to the domain. The system can optionally associate one or more partitions with a tenant, for use by the tenant.

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 and resource groups,

wherein each partition provides an administrative and runtime subdivision of the domain and can include one or more resource groups, and

wherein each resource group is a collection of deployable applications or resources that can reference a resource group template.

2. The system of claim 1, wherein the system can optionally associate one or more partitions with a tenant, for use by the tenant.

3. The system of claim 1, wherein each resource group template includes one or more related applications together with resources upon which those applications depend.

4. The system of claim 1, wherein the plurality of deployable resources comprises one or more of partition-aware resources, and partition-unaware resources.

5. The system of claim 1, wherein each partition can be associated with a local namespace.

6. The system of claim 1, wherein each partition can be associated with a partition name or identifier, which enables the system to determine a partition context so that requests can be communicated to appropriate partitions.

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

8. The system of claim 1, wherein the system supports multiple edit sessions of the partitions.

9. The system of claim 1, wherein each resource group, or the partition which includes that resource group, can be associated with a virtual target information that defines a target to which that resource group or partition should be targeted and deployed, and wherein a web tier component includes a routing information, which maps the virtual target for a particular partition to a corresponding target, so that requests for that partition are directed to the appropriate target.

10. 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 and resource groups,

wherein each partition provides an administrative and runtime subdivision of the domain and can include a resource group, and

wherein each resource group is a collection of deployable applications or resources that can reference a resource group template.

11. The method of claim 10, further comprising optionally associating one or more partitions with a tenant, for use by the tenant.

12. The method of claim 10, wherein each resource group template includes one or more related applications together with resources upon which those applications depend.

13. The method of claim 10, wherein the plurality of deployable resources comprises one or more of partition-aware resources, and partition-unaware resources.

14. The method of claim 10, wherein each partition can be associated with a local namespace.

15. The method of claim 10, wherein each partition can be associated with a partition name or identifier, which enables a partition context to be determined so that requests can be communicated to appropriate partitions.

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

17. The method of claim 10, further comprising providing support for multiple edit sessions of the partitions.

18. The method of claim 10, wherein each resource group, or the partition which includes that resource group, can be associated with a virtual target information that defines a target to which that resource group or partition should be targeted and deployed, and wherein a web tier component includes a routing information, which maps the virtual target for a particular partition to a corresponding target, so that requests for that partition are directed to the appropriate target.

19. 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 and resource groups,

wherein each partition provides an administrative and runtime subdivision of the domain and can include a resource group, and

wherein each resource group is a collection of deployable applications or resources that can reference a resource group template.
