Abstract

In accordance with an embodiment, described herein is a system and method for supporting patching in a multi-tenant application server environment. The system can associate one or more partitions with a tenant, for use by that tenant, wherein a partition is a runtime and administrative subdivision or slice of a domain. A patching process can take advantage of high-availability features provided by an application server clustering environment, to apply patches in a controlled, rolling restart, which maintains a domain's ability to operate without interruption, or with zero downtime. The process can be used to automate complex or long running tasks, including preserving an unpatched or prior version of an application server, application, or other software component for possible rollback, or providing automatic reversion in the event of an unrecoverable error.

First claim

What is claimed is:

1. A system comprising a multitenant application server environment, comprising:
one or more computers, including a multitenant application server environment executing thereon, together with
a plurality of deployable resources, which are used within the multitenant application server environment,
a plurality of partitions, wherein each partition, of the plurality of partitions, provides a subdivision of a domain that provides a runtime for use by that partition, of the plurality of partitions, and
wherein the system enables each partition, of the plurality of partitions, to be associated with a tenant of the multitenant application server environment, for use by the tenant of the multitenant application server environment;
wherein the system associates one or more partitions and resource groups with a tenant of the multitenant application server environment, for use by the tenant of the multitenant application server environment; and
wherein the system provides one or more high availability features within the multitenant application server environment to apply updates in a controlled manner that maintains the domain's ability to operate without interruption, including:
during a rollout of an update associated with a tenant environment, communicating with a load balancer to control traffic to particular managed server instances, of a plurality of managed server instances, associated with the tenant environment; and
during the rollout of the update associated with the tenant environment, upon receiving a request directed to a session associated with the tenant environment:
attempting to load the session at a first managed server instance, of the plurality of managed server instances, associated with the tenant environment, and
if the first managed server instance, of the plurality of managed server instances, associated with the tenant environment is not available, then directing the request to a second managed server instance, of the plurality of managed server instances, associated with the tenant environment having a replicated session data for the session.

2. The system of claim 1 , further comprising an orchestration framework that provides monitoring and error handling of a patching process.

3. The system of claim 1 , wherein each of one or more resource group templates includes one or more related applications together with resources upon which the one or more related applications depend.

4. The system of claim 1 , further comprising a node manager which supports patching within the multitenant application server environment.

5. The system of claim 1 , wherein the system is used to apply patches to nodes in a clustered environment.

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

7. A method for use with a multitenant application server environment, comprising:
providing, at one or more computers, a multitenant application server environment executing thereon;
providing a plurality of deployable resources, which are used within the multitenant application server environment;
providing a plurality of partitions, wherein each partition, of the plurality of partitions, provides a subdivision of a domain that provides a runtime for use by that partition, of the plurality of partitions;
enabling each partition, of the plurality of partitions, to be associated with a tenant of the multitenant application server environment, for use by the tenant of the multitenant application server environment;
associating one or more partitions and resource groups with a tenant of the multitenant application server environment, for use by the tenant of the multitenant application server environment; and
providing one or more high availability features within the multitenant application server environment to apply updates in a controlled manner that maintains the domain's ability to operate without interruption, including:
during a rollout of an update associated with a tenant environment, communicating with a load balancer to control traffic to particular managed server instances, of a plurality of managed server instances, associated with the tenant environment; and
during the rollout of the update associated with the tenant environment, upon receiving a request directed to a session associated with the tenant environment:
attempting to load the session at a first managed server instance, of the plurality of managed server instances, associated with the tenant environment, and
if the first managed server instance, of the plurality of managed server instances, associated with the tenant environment is not available, then directing the request to a second managed server instance, of the plurality of managed server instances, associated with the tenant environment having a replicated session data for the session.

8. The method of claim 7 , further comprising using an orchestration framework that provides monitoring and error handling of a patching process.

9. The method of claim 7 , wherein each of one or more resource group templates includes one or more related applications together with resources upon which the one or more related applications depend.

10. The method of claim 7 , further comprising using a node manager to support patching within the multitenant application server environment.

11. The method of claim 7 , wherein the method is used to apply patches to nodes in a clustered environment.

12. The method of claim 7 , wherein the method is performed within a cloud environment to support multiple tenants operating within the cloud environment.

13. 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 the one or more computers, a multitenant application server environment executing thereon;
providing a plurality of deployable resources, which are used within the multitenant application server environment;
providing a plurality of partitions, wherein each partition, of the plurality of partitions, provides a subdivision of a domain that provides a runtime for use by that partition, of the plurality of partitions;
enabling each partition, of the plurality of partitions, to be associated with a tenant of the multitenant application server environment, for use by the tenant of the multitenant application server environment;
associating one or more partitions and resource groups with a tenant of the multitenant application server environment, for use by the tenant of the multitenant application server environment; and
providing one or more high availability features within the multitenant application server environment to apply updates in a controlled manner that maintains the domain's ability to operate without interruption, including:
during a rollout of an update associated with a tenant environment, communicating with a load balancer to control traffic to particular managed server instances, of a plurality of managed server instances, associated with the tenant environment; and
during the rollout of the update associated with the tenant environment, upon receiving a request directed to a session associated with the tenant environment:
attempting to load the session at a first managed server instance, of the plurality of managed server instances, associated with the tenant environment, and
if the first managed server instance, of the plurality of managed server instances, associated with the tenant environment is not available, then directing the req
