Abstract

In accordance with an embodiment, described herein is a system and method for use of a multi-tenant application server with a multitasking virtual machine. The multi-tenant application server enables the definition of one or more partitions that provide a runtime and administrative subdivision or slice of an application server domain; while the multitasking virtual machine enables safe, secure, and scalable multitasking of software applications. Applications can be deployed a resource group scoped either to a domain or to a particular partition, or to a resource group template at the domain level. Partitions running on a managed server instance within the domain can share the multitasking virtual machine, which provides each partition with its own subdivision or slice of that multitasking virtual machine.

Claims

1. A system for use of a multi-tenant application server environment with a multitasking virtual machine, comprising:

one or more computers, including

a multitasking virtual machine that enables multitasking of software applications, and

an application server environment that executes on, and is associated with, the multitasking virtual machine, together with a plurality of partitions,

wherein each partition of the plurality of partitions provides an administrative and runtime subdivision of an application server domain, and

wherein the application server environment enables association of one or more partitions with a tenant, for use by the tenant; and

wherein the system enables each partition, of the plurality of partitions, to share the multi-tasking virtual machine, which provides that each partition has or is otherwise associated with its own subdivision of the multi-tasking virtual machine, for use by that partition.

2. The system of claim 1, wherein each partition of the plurality of partitions executes as a task within the multi-tasking virtual machine, including that a first partition of the plurality of partitions is associated with or otherwise uses a first task of the multi-tasking virtual machine, and a second partition of the plurality of partitions is associated with or otherwise uses a second task of the multi-tasking virtual machine.

3. The system of claim 2, wherein the multi-tasking virtual machine provides that each of the plurality of tasks, that are associated with different partitions, maintains data that is private to that task and partition in a respective private storage area of the multi-tasking virtual machine.

4. The system of claim 1, wherein each partition providing an administrative and runtime subdivision of the application server domain is associated with a partition identifier and configuration, and can contain applications and/or refer to domain-wide resources through the use of resource groups and resource group templates.

5. The system of claim 4, wherein a resource group is a named, fully-qualified collection of deployable resources that can be defined either at a domain or partition level, and can reference a resource group template.

6. A method for use of a multi-tenant application server environment with a multitasking virtual machine, comprising:

providing, at one or more computers,

a multitasking virtual machine that enables multitasking of software applications, and

an application server environment that executes on, and is associated with, the multitasking virtual machine, together with a plurality of partitions,

wherein each partition of the plurality of partitions provides an administrative and runtime subdivision of an application server domain, and

wherein the application server environment enables association of one or more partitions with a tenant, for use by the tenant; and

enabling each partition, of the plurality of partitions, to share the multi-tasking virtual machine, which provides that each partition has or is otherwise associated with its own subdivision of the multi-tasking virtual machine, for use by that partition.

7. The method of claim 6, wherein each partition of the plurality of partitions executes as a task within the multi-tasking virtual machine, including that a first partition of the plurality of partitions is associated with or otherwise uses a first task of the multi-tasking virtual machine, and a second partition of the plurality of partitions is associated with or otherwise uses a second task of the multi-tasking virtual machine.

8. The method of claim 7, wherein the multi-tasking virtual machine provides that each of the plurality of tasks, that are associated with different partitions, maintains data that is private to that task and partition in a respective private storage area of the multi-tasking virtual machine.

9. The method of claim 6, wherein each partition providing an administrative and runtime subdivision of the application server domain is associated with a partition identifier and configuration, and can contain applications and/or refer to domain-wide resources through the use of resource groups and resource group templates.

10. The method of claim 9, wherein a resource group is a named, fully-qualified collection of deployable resources that can be defined either at a domain or partition level, and can reference a resource group template.

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, at one or more computers,

a multitasking virtual machine that enables multitasking of software applications, and

an application server environment that executes on, and is associated with, the multitasking virtual machine, together with a plurality of partitions,

wherein each partition of the plurality of partitions provides an administrative and runtime subdivision of an application server domain, and

wherein the application server environment enables association of one or more partitions with a tenant, for use by the tenant; and

enabling each partition, of the plurality of partitions, to share the multi-tasking virtual machine, which provides that each partition has or is otherwise associated with its own subdivision of the multi-tasking virtual machine, for use by that partition.

12. The non-transitory computer readable storage medium of claim 11, wherein each partition of the plurality of partitions executes as a task within the multi-tasking virtual machine, including that a first partition of the plurality of partitions is associated with or otherwise uses a first task of the multi-tasking virtual machine, and a second partition of the plurality of partitions is associated with or otherwise uses a second task of the multi-tasking virtual machine.

13. The non-transitory computer readable storage medium of claim 12, wherein the multi-tasking virtual machine provides that each of the plurality of tasks, that are associated with different partitions, maintains data that is private to that task and partition in a respective private storage area of the multi-tasking virtual machine.

14. The non-transitory computer readable storage medium of claim 11, wherein each partition providing an administrative and runtime subdivision of the application server domain is associated with a partition identifier and configuration, and can contain applications and/or refer to domain-wide resources through the use of resource groups and resource group templates.

15. The non-transitory computer readable storage medium of claim 14, wherein a resource group is a named, fully-qualified collection of deployable resources that can be defined either at a domain or partition level, and can reference a resource group template.
