Abstract

In accordance with an embodiment, described herein is a system and method for providing an end-to-end lifecycle in a multi-tenant application server environment. A lifecycle manager enables configuration integration across different components, for example application servers, traffic directors or load balancers, and database or other components, which may have their own partition-specific configurations. In accordance with an embodiment, the end-to-end lifecycle infrastructure includes a plugin-based mechanism which enables the different components within a multi-tenant application server environment to use a lifecycle plugin to provide their own component-specific lifecycle functionality. In accordance with an embodiment, the system includes support for a tenant onboarding functionality, which can be used to onboard a tenant for a service to a particular partition. In accordance with an embodiment, the system supports the use of a global runtime within the multi-tenant application server environment.

Claims

1. A system for supporting a global runtime in a multitenant application server environment, comprising

one or more computers, comprising an application server environment executing thereon 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 one or more 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 for one or more of the deployable resources;

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

a global runtime that is scoped to the application server domain, wherein one or more resource groups can be specified at the domain level for use in the global runtime, including that the global runtime performs operations at a tenant switching interface that determines access by the global runtime to switch a thread context temporarily from a global context to a tenant context associated with a particular tenant, and to execute an operation at an application associated with a particular partition on behalf of the tenant.

2. The system of claim 1, wherein one or more resources in a resource group are targeted to all targets specified for the resource group, and whereupon the resource group being targeted to a cluster of managed servers, any applications included within the resource group are run on all of the managed servers in the cluster.

3. The system of claim 1, further comprising, for each tenant of a plurality of tenants, a tenant context associated with the tenant that can be mapped to a partition context for use with the tenant.

4. The system of claim 1, further comprising one or more resource group templates that enable information to be associated with a referenced resource group template, to indicate partition-specific information for one or more of the deployable resources.

5. The system of claim 1, wherein the tenant switching interface enables switching from a global level context to the tenant context associated with the particular tenant, to execute the operation on behalf of the particular partition.

6. The system of claim 1, wherein each component of the one or more components is associated with a plugin that provides an interface that enables lifecycle operations to be performed with that component.

7. The system of claim 1, whereupon a request being received at the application server environment that is directed to the particular partition, an invocation context object is created to represent the invocation, wherein the invocation context object includes an indication of the particular partition associated with the request.

8. The system of claim 7, wherein the global runtime includes one or more applications that run at the domain level to configure tenant-specific applications running a plurality of partitions of the domain, including that, for each partition of the plurality of partitions, the global runtime performs operations at the tenant switching interface to execute in the context of that each partition and its associated tenant context.

9. The system of claim 8, wherein the global runtime is initialized before initialization of the plurality of partitions, including that resource groups defined in the global runtime are started before resource groups defined in the plurality of partitions.

10. A method for supporting a global runtime in a multitenant application server environment, comprising:

providing, at one or more computers, an application server environment executing thereon 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 one or more 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 for one or more of the deployable resources;

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

providing a global runtime that is scoped to the application server domain, wherein one or more resource groups can be specified at the domain level for use in the global runtime, including that the global runtime performs operations at a tenant switching interface that determines access by the global runtime to switch a thread context temporarily from a global context to a tenant context associated with a particular tenant, and to execute an operation at an application associated with a particular partition on behalf of the tenant.

11. The method of claim 10, wherein one or more resources in a resource group are targeted to all targets specified for the resource group, and whereupon the resource group being targeted to a cluster of managed servers, any applications included within the resource group are run on all of the managed servers in the cluster.

12. The method of claim 10, further comprising, for each tenant of a plurality of tenants, providing a tenant context associated with the tenant that can be mapped to a partition context for use with the tenant.

13. The method of claim 10, further comprising providing one or more resource group templates that enable information to be associated with a referenced resource group template, to indicate partition-specific information for one or more of the deployable resources.

14. The method of claim 10, wherein the tenant switching interface enables switching from a global level context to the tenant context associated with the particular tenant, to execute the operation on behalf of the particular partition.

15. The method of claim 10, wherein each component of the one or more components is associated with a plugin that provides an interface that enables lifecycle operations to be performed with that component.

16. 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 method 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 one or more 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 for one or more of the deployable resources;

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

providing a global runtime that is scoped to the application server domain, wherein one or more resource groups can be specified at the domain level for use in the global runtime, including that the global runtime performs operations at a tenant switching interface that determines access by the global runtime to switch a thread context temporarily from a global context to a tenant context associated with a particular tenant, and to execute an operation at an application associated with a particular partition on behalf of the tenant.

17. The non-transitory computer readable storage medium of claim 16, wherein one or more resources in a resource group are targeted to all targets specified for the resource group, and whereupon the resource group being targeted to a cluster of managed servers, any applications included within the resource group are run on all of the managed servers in the cluster.

18. The non-transitory computer readable storage medium of claim 16, further comprising, for each tenant of a plurality of tenants, providing a tenant context associated with the tenant that can be mapped to a partition context for use with the tenant.

19. The non-transitory computer readable storage medium of claim 16, further comprising providing one or more resource group templates that enable information to be associated with a referenced resource group template, to indicate partition-specific information for one or more of the deployable resources.
