Abstract

In accordance with an embodiment, described herein is a system and method for supporting multi-tenancy in an application server, cloud, on-premise, or other environment, which enables categories of components and configurations to be associated with particular application instances or partitions. Resource group templates define, at a domain level, collections of deployable resources that can be referenced from resource groups. Each resource group is a named, fully-qualified collection of deployable resources that can reference a resource group template. A partition provides an administrative and runtime subdivision of the domain, and contains one or more resource groups. Each resource group can reference a resource group template, to bind deployable resources to partition-specific values, for use by the referencing partition. A tenant of the application server or cloud environment can be associated with a partition, or applications deployed therein, for use by that tenant.

First claim

What is claimed is:

1. A system for supporting multi-tenancy in an application server, a cloud environment, or other environment, comprising:
a computer that includes one or more processors and an application server, a cloud environment, or other environment executing thereon, and having a domain configuration that is used at runtime to define a domain for execution of software applications, and a plurality of resources accessible within the domain and adapted for use by the software applications;
wherein the system operates at runtime to define a plurality of partitions of the domain, including wherein:
each partition, of the plurality of partitions, is associated with a partition identifier that identifies the partition; and
each partition, of the plurality of partitions, provides a subdivision of the domain for execution of the software applications and use of the plurality of resources within a context of the partition; and

wherein each partition, of the plurality of partitions, is associated with a virtual target associated with the partition, and wherein upon a request received from a client directed to a particular virtual target, the system:
determines a particular partition associated with the received request, and a particular partition identifier, and stores the particular partition identifier in a request execution context; and
routes the received request to the particular partition, for use by the software applications associated with the particular partition.

2. The system of claim 1 , wherein the system is provided within a cloud environment that enables one or more partitions to be associated with a tenant for use by the tenant;
wherein a partition identifier is associated with a tenant identifier; and
wherein a tenant-aware application enables use of the tenant identifier to handle multiple tenants that are using a single instance of the tenant-aware application.

3. The system of claim 1 , wherein:
a first partition is associated with a first partition identifier, and a first plurality of resources associated with the first partition, and is accessible by clients communicating requests to a first virtual target; and
a second partition is associated with a second partition identifier, and a second plurality of resources associated with the second partition, and is accessible by clients communicating requests to a second virtual target.

4. The system of claim 1 , wherein the system includes a networking layer that associates incoming requests with partition identifiers based on a request Uniform Resource Locator (URL), and wherein the networking layer determines a target partition identifier for the received request, and adds the determined target partition identifier to the received request's execution context.

5. The system of claim 1 , wherein the system includes support for channels, including a channel for use by all partitions, and a dedicated channel for each partition of the plurality of partitions, and wherein if a partition is specified, then the partition identifier is used to determine a suitable channel.

6. A method for supporting multi-tenancy in an application server, a cloud environment, or other environment, comprising:
providing, at a computer that includes one or more processors and an application server, a cloud environment, or other environment executing thereon, and having a domain configuration that is used at runtime to define a domain for execution of software applications, and a plurality of resources accessible within the domain and adapted for use by the software applications;
wherein a system operates at runtime to define a plurality of partitions of the domain, including wherein:
each partition, of the plurality of partitions, is associated with a partition identifier that identifies the partition; and
each partition, of the plurality of partitions, provides a subdivision of the domain for execution of the software applications and use of the plurality of resources within a context of the partition; and

wherein each partition, of the plurality of partitions, is associated with a virtual target associated with the partition, and wherein upon a request received from a client directed to a particular virtual target, the system:
determines a particular partition associated with the received request, and a particular partition identifier, and stores the particular partition identifier in a request execution context; and
routes the received request to the particular partition, for use by the software applications associated with the particular partition.

7. The method of claim 6 , wherein the system is provided within a cloud environment that enables one or more partitions to be associated with a tenant for use by the tenant;
wherein a partition identifier is associated with a tenant identifier; and
wherein a tenant-aware application enables use of the tenant identifier to handle multiple tenants that are using a single instance of the tenant-aware application.

8. The method of claim 6 , wherein:
a first partition is associated with a first partition identifier, and a first plurality of resources associated with the first partition, and is accessible by clients communicating requests to a first virtual target; and
a second partition is associated with a second partition identifier, and a second plurality of resources associated with the second partition, and is accessible by clients communicating requests to a second virtual target.

9. The method of claim 6 , wherein the system includes a networking layer that associates incoming requests with partition identifiers based on a request Uniform Resource Locator (URL), and wherein the networking layer determines a target partition identifier for the received request, and adds the determined target partition identifier to the received request's execution context.

10. The method of claim 6 , wherein the system includes support for channels, including a channel for use by all partitions, and a dedicated channel for each partition of the plurality of partitions, and wherein if a partition is specified, then the partition identifier is used to determine a suitable channel.

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 a method comprising:
providing, at a computer that includes one or more processors and an application server, a cloud environment, or other environment executing thereon, and having a domain configuration that is used at runtime to define a domain for execution of software applications, and a plurality of resources accessible within the domain and adapted for use by the software applications;
wherein a system operates at runtime to define a plurality of partitions of the domain, including wherein:
each partition, of the plurality of partitions, is associated with a partition identifier that identifies the partition; and
each partition, of the plurality of partitions, provides a subdivision of the domain for execution of the software applications and use of the plurality of resources within a context of the partition; and

wherein each partition, of the plurality of partitions, is associated with a virtual target associated with the partition, and wherein upon a request received from a client directed to a particular virtual target, the system:
determines a particular partition associated with the received request, and a particular partition identifier, and stores the particular partition identifier in a request execution context; and
routes the received request to the particular partition, for use by the software applications assoc
