Abstract

In accordance with an embodiment, described herein are a system and method for partition-scoped patching in an application server environment. A computer environment includes an application server, for example a multitenant application server, that supports the use of one or more partitions, wherein each partition provides an administrative and runtime subdivision of a domain. During a partition-scoped rollout of a patch or update, to a resource group or application within a plurality of servers or clusters of servers, the resource group or application can be updated within a targeted partition, using a patch orchestrator and partition lifecycle runtime interface, without affecting the operation of other partitions at those servers or clusters of servers. One or more session handling flags can be used, to enable sessions and/or requests that are associated with the targeted partition, to be handled by a traffic director, during the patching process.

Claims

1. A system for partition-scoped patching in an application server environment, comprising:

a computer that includes an application server, for example a multitenant application server, that supports the use of one or more partitions, wherein each partition provides an administrative and runtime subdivision of a domain;

a patch orchestrator and partition lifecycle runtime interface, that enables a partition-scoped rollout of a patch to a resource group or application within a targeted partition at one or more servers or clusters of servers, to update the resource group or application within the targeted partition; and

wherein one or more session handling flags are used, during the partition-scoped rollout, to control the handling of sessions and requests associated with the targeted partition to servers that include the targeted partition.

2. The system of claim 1, wherein the patch is applied to the resource group or application within the targeted partition at the one or more servers or clusters of servers, using a rolling restart process.

3. The system of claim 1, wherein the patch is applied to the resource group or application within the targeted partition at the one or more servers or clusters of servers, without affecting the operation of other partitions at those servers or clusters of servers.

4. The system of claim 1, wherein the one or more session handling flags are used in association with a web-tier traffic director, to control how the sessions and requests that are associated with the targeted partition, are associated with or directed to appropriate servers that include the targeted partition.

5. The system of claim 1, wherein the partition-scoped rollout is provided within a cloud environment having a plurality of tenants, and wherein each tenant can be associated with at least one partition.

6. A method for partition-scoped patching in an application server environment, comprising:

providing, at a computer, an application server having one or more partitions, wherein each partition provides an administrative and runtime subdivision of a domain;

performing, using a patch orchestrator and partition lifecycle runtime interface, a partition-scoped rollout of a patch to a resource group or application within a targeted partition at one or more servers or clusters of servers, to update the resource group or application within the targeted partition; and

wherein one or more session handling flags are used, during the partition-scoped rollout, to control the handling of sessions and requests associated with the targeted partition to servers that include the targeted partition.

7. The method of claim 6, wherein the patch is applied to the resource group or application within the targeted partition at the one or more servers or clusters of servers, using a rolling restart process.

8. The method of claim 6, wherein the patch is applied to the resource group or application within the targeted partition at the one or more servers or clusters of servers, without affecting the operation of other partitions at those servers or clusters of servers.

9. The method of claim 6, wherein the one or more session handling flags are used in association with a web-tier traffic director, to control how the sessions and requests that are associated with the targeted partition, are associated with or directed to appropriate servers that include the targeted partition.

10. The method of claim 6, wherein the partition-scoped rollout is provided within a cloud environment having a plurality of tenants, and wherein each tenant can be associated with at least one partition.

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 method comprising:

providing, at a computer, an application server having one or more partitions, wherein each partition provides an administrative and runtime subdivision of a domain;

performing, using a patch orchestrator and partition lifecycle runtime interface, a partition-scoped rollout of a patch to a resource group or application within a targeted partition at one or more servers or clusters of servers, to update the resource group or application within the targeted partition; and

wherein one or more session handling flags are used, during the partition-scoped rollout, to control the handling of sessions and requests associated with the targeted partition to servers that include the targeted partition.

12. The non-transitory computer readable storage medium of claim 11, wherein the patch is applied to the resource group or application within the targeted partition at the one or more servers or clusters of servers, using a rolling restart process.

13. The non-transitory computer readable storage medium of claim 11, wherein the patch is applied to the resource group or application within the targeted partition at the one or more servers or clusters of servers, without affecting the operation of other partitions at those servers or clusters of servers.

14. The non-transitory computer readable storage medium of claim 11, wherein the one or more session handling flags are used in association with a web-tier traffic director, to control how the sessions and requests that are associated with the targeted partition, are associated with or directed to appropriate servers that include the targeted partition.

15. The non-transitory computer readable storage medium of claim 11, wherein the partition-scoped rollout is provided within a cloud environment having a plurality of tenants, and wherein each tenant can be associated with at least one partition.
