Abstract

In accordance with an embodiment, described herein is a system and method for traffic director support in a multitenant application server environment. An exemplary method can provide one or more partitions, wherein each partition provides an administrative and runtime subdivision of the domain, one or more resource groups, wherein each of the one or more resource groups is associated with a partition of the one or more partition, one or more virtual targets, and an instance of a traffic director comprising a configuration. The method can target each of the one or more partitions and the one or more resource groups to a virtual target of the one or more virtual targets. The method can also configure the configuration of the traffic director, wherein the instance of a traffic director provides load balancing among one or more servers of a server pool.

Claims

1. A system for traffic director support in a multitenant application server environment, comprising:

one or more computers, including an application server environment executing thereon, together with

one or more partitions, wherein each partition provides an administrative and runtime subdivision of the domain,

one or more resource groups, wherein each of the one or more resource groups is associated with a partition of the one or more partition,

one or more virtual targets,

an instances of a traffic director, the instance of a traffic director comprising a configuration;

wherein each of the one or more partitions and the one or more resource groups are targeted to a virtual target of the one or more virtual targets;

wherein the configuration of the instance of a traffic director is configured to direct network traffic to the one or more partitions and the one or more resource groups, the configuration of the instance of the traffic director comprising one or more routes; and

wherein the instance of a traffic director provides load balancing among one or more servers of a server pool.

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

3. The system of claim 2, wherein each route is directed through a virtual target of the one or more virtual targets.

4. The system of claim 3, wherein upon a partition operation on a partition of the one or more partitions, a traffic director plugin updates the configuration of the instance of the traffic director.

5. The system of claim 4, wherein the partition operation is one of create, associate, dissociate, update, delete, and migrate.

6. The system of claim 3, wherein upon a runtime operation of the one or more partitions, a traffic director plugin updates the configuration of the instance of the traffic director.

7. The system of claim 6, wherein the runtime operation is of on scale up, scale down, quiesce, and start.

13. The method of claim 3, wherein upon a runtime operation of the one or more partitions, a traffic director plugin updates the configuration of the instance of the traffic director.

14. The method of claim 13, wherein the runtime operation is of on scale up, scale down, quiesce, and start.

8. A method for traffic director support in a multitenant application server environment, comprising:

providing, at one or more computers, including an application server environment executing thereon,

one or more partitions, wherein each partition provides an administrative and runtime subdivision of the domain,

one or more resource groups, wherein each of the one or more resource groups is associated with a partition of the one or more partition,

one or more virtual targets,

an instance of a traffic director, the instance of a traffic director comprising a configuration;

targeting each of the one or more partitions and the one or more resource groups to a virtual target of the one or more virtual targets; and

configuring the configuration of the instance of a traffic director to direct network traffic to the one or more partitions and the one or more resource groups, the configuration of the instance of the traffic director comprising one or more routes; and

wherein the instance of a traffic director provides load balancing among one or more servers of a server pool.

9. The method of claim 8, wherein the multitenant application server environment is provided within a cloud environment, to support multiple tenants operating within the cloud environment.

10. The method of claim 9, wherein each route is directed through a virtual target of the one or more virtual targets.

11. The method of claim 10, wherein upon a partition operation on a partition of the one or more partitions, a traffic director plugin updates the configuration of the instance of the traffic director.

12. The method of claim 11, wherein the partition operation is one of create, associate, dissociate, update, delete, and migrate.

15. A non-transitory computer readable storage medium, including instructions stored thereon for traffic director support in a multitenant application server environment, 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, including an application server environment executing thereon,

one or more partitions, wherein each partition provides an administrative and runtime subdivision of the domain,

one or more resource groups, wherein each of the one or more resource groups is associated with a partition of the one or more partition,

one or more virtual targets,

an instances of a traffic director, the instance of a traffic director comprising a configuration;

targeting each of the one or more partitions and the one or more resource groups to a virtual target of the one or more virtual targets; and

configuring the configuration of the instance of a traffic director to direct network traffic to the one or more partitions and the one or more resource groups, the configuration of the instance of the traffic director comprising one or more routes; and

wherein the instance of a traffic director provides load balancing among one or more servers of a server pool.

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

17. The non-transitory computer readable storage medium of claim 16, wherein each route is directed through a virtual target of the one or more virtual targets.

18. The non-transitory computer readable storage medium of claim 17, wherein upon a partition operation on a partition of the one or more partitions, a traffic director plugin updates the configuration of the instance of the traffic director.

19. The non-transitory computer readable storage medium of claim 18, wherein a partition operation is one of create, associate, dissociate, update, delete, and migrate.

20. The non-transitory computer readable storage medium of claim 17, wherein upon a runtime operation of the one or more partitions, a traffic director plugin updates the configuration of the instance of the traffic director, and wherein the runtime operation is of on scale up, scale down, quiesce, and start.
