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.

System and method for supporting multi-tenancy in an application server, cloud, or other environment

In accordance with an embodiment, described herein is a system and method for supporting partitions in a multitenant application server environment. 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.

System and method for supporting partitions in a multitenant application server environment

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.

System and method for partition migration in a multitenant application server environment

In accordance with an embodiment, described herein is a system and method for providing portable partitions in a multitenant application server environment. In accordance with an embodiment, the system enables a partition to be exported from first or source domain (e.g., a test domain), and imported into another second or target domain (e.g., a production domain). During creation or export of a partition archive, the partition archive is created which includes a partition configuration, resource group or resource group template information, and optionally application binaries. The partition archive can also include an interface that allows access to exportable or configurable values associated with the partition. During deployment or import of the partition archive to the target domain, the information in the partition archive, including the exportable or configurable values associated with the partition, are used to configure the partition for use in the target domain.

System and method for portable partitions in a multitenant application server environment

In accordance with an embodiment, described herein is a system and method for supporting the use of configuration tagging in a multitenant application server environment. In accordance with an embodiment, a user interface is provided which displays a domain structure, including partitions and target systems, and enables components of the domain to be associated with user-specified tags that are received from an administrator, including for example, a first component associated with a first set of one or more tag(s), and a second component associated with a second set of one or more tag(s), which are then associated with the corresponding domain component. For example, a virtual target or target system can be associated with a tag such as 'Gold', 'Silver' or &#x201c;Bronze&#x201d;. The tagged components can then be associated with the creation or definition of a partition.

System and method for configuration tagging in a multitenant application server environment

In accordance with an embodiment, described herein is a system and method for supporting the use of partition templates in a multitenant application server environment. A partition template, including a partition configurator and/or attributes, can be used to configure partitions deployed to a domain using that partition template. When a request is received to create a new partition, a selected partition template is determined. The partition configurator of that partition template is then used to configure and deploy the partition to the domain at a corresponding virtual target, which in turn is associated with a target system (e.g., a computer server, or a cluster). A plurality of partition templates can be provided, wherein each partition template can include its own partition configurator and/or attributes that can be used to configure partitions deployed to the domain using that partition template, including different configuration attributes for each partition template.
