System and method for partition migration in a multitenant application server environment
First Claim
1. A system for supporting partition migration in an application server environment, comprising:
- one or more computers, including an application server that enables deployment and execution of software applications, wherein the application server is associated with a domain configuration that is used at runtime to define a domain for execution of the software applications and a plurality of partitions of the domain,wherein each partition, of the plurality of partitions, is associated with a partition configuration, and provides a subdivision of the domain,wherein each resource group, of the one or more resource groups, is a collection of deployable applications or resources definable at a domain or partition level, andwherein a partition runs an included resource group using a partition-specific configuration, such that an instance of the applications or resources defined within the included resource group is configured specific to the partition;
wherein each particular resource group, or particular partition that includes the particular resource group, is associated with a virtual target information that defines a target to which the particular resource group or the particular partition is deployed; and
wherein the application server operates with a web tier component that includes a routing information which maps the virtual target for the particular partition to a corresponding target at a server or cluster, for use in directing requests for the particular partition, including that, when the particular partition is migrated, session state data associated with the particular partition and sessions operating thereon is replicated to a new target, wherein subsequent requests received at the web tier component for the particular partition are directed to the new target.

Abstract
In accordance with an embodiment, described herein is a system and method for partition migration in a multitenant application server environment. Each resource group, or partition which includes that resource group, can be associated with a virtual target (e.g., virtual host) information that defines a target to which that resource group or partition should be targeted and deployed. A web tier component (e.g., Oracle Traffic Director) includes a routing information, which maps the virtual target for a partition to a corresponding target such as a server or cluster, so that requests for that partition are directed to the appropriate target, for example as part of one or more sessions. When a partition is migrated, session information is replicated between an original target and a new target, and the web tier component provided with a revised routing information, so that subsequent requests for that partition are directed to the new target.

15. 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 an application server that enables deployment and execution of software applications, wherein the application server is associated with a domain configuration that is used at runtime to define a domain for execution of the software applications and a plurality of partitions of the domain, wherein each partition, of the plurality of partitions, is associated with a partition configuration, and provides a subdivision of the domain, wherein each resource group, of the one or more resource groups, is a collection of deployable applications or resources definable at a domain or partition level, and wherein a partition runs an included resource group using a partition-specific configuration, such that an instance of the applications or resources defined within the included resource group is configured specific to the partition; wherein each particular resource group, or particular partition that includes the particular resource group, is associated with a virtual target information that defines a target to which the particular resource group or the particular partition is deployed; and wherein the application server operates with a web tier component that includes a routing information which maps the virtual target for the particular partition to a corresponding target at a server or cluster, for use in directing requests for the particular partition, including that, when the particular partition is migrated, session state data associated with the particular partition and sessions operating thereon is replicated to a new target, wherein subsequent requests received at the web tier component for the particular partition are directed to the new target. - View Dependent Claims (16, 17, 18, 19, 20)
