In accordance with an embodiment, an application server administrator (e.g., a WLS administrator) can create or delete partitions; while a partition administrator can administer various aspects of a partition, for example create resource groups, deploy applications to a specific partition, and reference specific realms for a partition. Resource groups can be globally defined at the domain, or can be specific to a partition. Applications can be deployed to a resource group template at the domain level, or to a resource group scoped to a partition or scoped to the domain. The system can optionally associate one or more partitions with a tenant, for use by the tenant. ## Claims ### Claim 1 A system for supporting multi-tenancy in a cloud or other computing environment, comprising: one or more computers including one or more processors and a cloud computing 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 partitions; wherein each partition-level resource group within a partition is associated with a virtual target information that defines a target to which that resource group is deployed, including that: a first partition includes a first partition-level resource group that contains one or more resources or applications for use with the first partition and wherein the first partition-level resource group is accessible via a first virtual target, and a second partition includes a second partition-level resource group that contains one or more resources or applications for use with the second partition and wherein the first partition-level resource group is accessible via a second virtual target; wherein the first and second virtual targets associated with the first and second partition-level resource groups are mapped to one or more servers, for use in directing requests to the partitions; and wherein software applications deployed to a particular partition execute at a virtual target and with the resources or applications associated with the particular partition, including wherein upon receipt of a request directed to the particular partition, the system associates a partition invocation context with the received request, and executes the request at its partition-specific resources or applications. ### Claim 2 (depends on 1) The system of claim 1, wherein the system enables one or more partitions to be associated with a tenant, and a partition-specific database resource, for use by the tenant. ### Claim 3 (depends on 1) 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. ### Claim 4 (depends on 1) 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 a first tenant and clients associated therewith; 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 a second tenant and clients associated therewith. ### Claim 5 (depends on 1) The system of claim 1, wherein a partition-level resource group can reference a resource group template that binds resources of the resource group template to partition-specific values, including wherein a partition object containing the resource group sets the value of tokens in the resource group template, for use during activating the resource group template for the partition-level resource group. ### Claim 6 (depends on 1) The system of claim 1, wherein a networking layer 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. ### Claim 7 A method for supporting multi-tenancy in a cloud computing environment, comprising: providing one or more computers including one or more processors and a cloud computing 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 partitions; associating each partition-level resource group within a partition with a virtual target information that defines a target to which that resource group is deployed, including that: a first partition includes a first partition-level resource group that contains one or more resources or applications for use with the first partition and wherein the first partition-level resource group is accessible via a first virtual target, and a second partition includes a second partition-level resource group that contains one or more resources or applications for use with the second partition and wherein the first partition-level resource group is accessible via a second virtual target; wherein the first and second virtual targets associated with the first and second partition-level resource groups are mapped to one or more servers, for use in directing requests to the partitions; and wherein software applications deployed to a particular partition execute at a virtual target and with the resources or applications associated with the particular partition, including wherein upon receipt of a request directed to the particular partition, the system associates a partition invocation context with the received request, and executes the request at its partition-specific resources or applications. ### Claim 8 (depends on 7) The method of claim 7, wherein the system enables one or more partitions to be associated with a tenant, and a partition-specific database resource, for use by the tenant. ### Claim 9 (depends on 7) The method of claim 7, 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;
