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.

Abstract: 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.

Abstract: In accordance with an embodiment, described herein is a system and method for managed server independence for deployment (MSI-D) of software applications and libraries, for use in a cloud computing, application server, or other environment. Software applications or libraries can be prepared for deployment as multi-version format application(s) or library(s). A deployment configuration tool enables use of an input file which specifies one or more deployment configuration overrides data that provide additional pieces of information for each MSI-D/multi-version format application and library. A managed server can independently poll for changes to the deployment configuration overrides, for example to update one or more of its deployed applications or libraries, from a first version to a second version. The system can be used to provide eventual consistency of the deployed application and library versions within a plurality of managed servers.

Abstract: In accordance with an embodiment, described herein is a system and method for resource isolation and consumption in an application server environment. The system can provide, at one or more computers, including an application server environment executing thereon, a plurality of resources which can be used within the application server environment, and one or more partitions, wherein each partition provides an administrative and runtime subdivision of a domain. The system can also configure a resource consumption management module to monitor each partition's usage of the plurality of resources. The resource consumption management module can comprise at least one member of the group consisting of resource reservations, resource constraints, and resource notifications.

Abstract: In accordance with an embodiment, described herein is a system and method for supporting a situational configuration in an application server environment includes at least one computer having an application server, enterprise, cloud computing, or other computing environment executing thereon, together with one or more managed server instances that operate as part of a domain and a situational configuration file defining server configuration setting changes and an expiration. The server configuration changes are loaded if the one or more managed server instances detect an addition of the situational configuration file or a change in the situational configuration file. The server configuration changes are unloaded if the one or more managed server instances detect deletion of the situational configuration or expiration of the situational configuration.

Abstract: In accordance with an embodiment, described herein is a system and method for classloading in a multitenant application server environment. The system includes a domain with a plurality of partitions, and a resource group template including one or more applications, each configured with code shareable across the plurality of partitions. A class loader hierarchy can be created for each application instance in a partition, wherein the class loader hierarchy includes a class loader structure for that application instance, a partition class loader for the partition, and a shared application class loader for all instances of that application. At runtime, the class loader structure for an application instance can use the partition class loader as a parent class loader to load classes visible to the partition, and use the shared application class loader as an alternative parent class loader.
