System and method for partition-scoped patching in an application server environment
First Claim
1. A system for partition-scoped patching in an application server environment, comprising:
- a computer that includes an application server environment that supports use of one or more partitions,wherein each partition provides an administrative and runtime subdivision of an application server domain,wherein the one or more partitions are provided at servers or clusters of servers, andwherein each server that provides the one or more partitions includes a resource group or application for use with the one or more partitions;
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 of the one or more partitions at the servers or clusters of servers, to update the resource group or application within the targeted partition, wherein the patch is applied to the resource group or application within the targeted partition at the servers or clusters of servers, using the partition lifecycle runtime interface, without affecting the operation of other partitions at those servers or clusters of servers; and
wherein one or more session handling flags are used, during the partition-scoped rollout, to propagate session information and control the handling of sessions and requests associated with the targeted partition by a traffic director, to the servers or clusters of servers that include the targeted partition, including, for each server to be patched;
shutting down the targeted partition at the server,updating a version of the resource group or application within the targeted partition,restarting only the targeted partition and the updated version of the resource group and application within the targeted partition, andwhile the server is shutdown, flagging a status of the server to the traffic director indicative of that server'"'"'s unavailability, to enable the traffic director to contact another of the servers to process requests associated with the targeted partition.

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.

5. 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 an application server domain, wherein the one or more partitions are provided at servers or clusters of servers, and wherein each server that provides the one or more partitions includes a resource group or application for use with the one or more partitions; 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 of the one or more partitions at the servers or clusters of servers, to update the resource group or application within the targeted partition, wherein the patch is applied to the resource group or application within the targeted partition at the servers or clusters of servers, using the partition lifecycle runtime interface, without affecting the operation of other partitions at those servers or clusters of servers; and wherein one or more session handling flags are used, during the partition-scoped rollout, to propagate session information and control the handling of sessions and requests associated with the targeted partition by a traffic director, to the servers or clusters of servers that include the targeted partition, including, for each server to be patched; shutting down the targeted partition at the server, updating a version of the resource group or application within the targeted partition, restarting only the targeted partition and the updated version of the resource group and application within the targeted partition, and while the server is shutdown, flagging a status of the server to the traffic director indicative of that server'"'"'s unavailability, to enable the traffic director to contact another of the servers to process requests associated with the targeted partition. - View Dependent Claims (6, 7, 8)
