Abstract: In accordance with an embodiment, described herein is a system and method for supporting clustering in a multitenant application server environment. The system includes a domain with a plurality of server clusters, and a plurality of partitions, wherein each cluster is homogenously configured and targeted by one or more partitions. An application programming interface (API) can be used to initiate a resource group across-cluster migration within a partition. The API can invoke a replication manager, which queries a target cluster for a runtime topology for use in determining where to store primary session; migrates the primary session to a determined server instance in the target cluster. Additional clustering features, such as cluster messaging service, leasing service, singleton service management, session replication, clustered JNDI, and use of domain front-end load balancing, can be supported.

Abstract: In accordance with an embodiment, described herein is a system and method for supporting patching in a multi-tenant application server environment. The system can associate one or more partitions with a tenant, for use by that tenant, wherein a partition is a runtime and administrative subdivision or slice of a domain. A patching process can take advantage of high-availability features provided by an application server clustering environment, to apply patches in a controlled, rolling restart, which maintains a domain's ability to operate without interruption, or with zero downtime. The process can be used to automate complex or long running tasks, including preserving an unpatched or prior version of an application server, application, or other software component for possible rollback, or providing automatic reversion in the event of an unrecoverable error.

Abstract: Provided are techniques for heuristic and non-semantic prediction of the cost to find and review data that is relevant to a task. A corpus of documents is accessed for a domain. Terms associated with the domain are accessed, where the terms have an order on a list. For each of the documents, term positional dispersion is determined for each of the terms in the ordered list associated with the domain. Then, a document review quanta is determined for the document based on a summation of the term positional dispersion for each term in that document adjusted by a weight. A subset of documents in the corpus of documents are selected that are to be reviewed based on the document review quanta for each of the selected documents exceeding a threshold.

Abstract: A system and method for providing a service management engine for use with a cloud computing environment. In accordance with an embodiment, enterprise software applications (e.g., Fusion Middleware applications) can be instantiated as services within a cloud platform, where they are then made accessible by other (e.g., customer) applications. In an embodiment, a service management engine (SME), in communication with an orchestration engine, can be used to provision services as one or more different service types, according to a service definition package (SDP). Service types can be instantiated according to the configuration of the cloud platform itself, and the contents of the SDP, including discovering, provisioning, and associating service types with system resources, to address different customer requirements.

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 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.

The system administrator can additionally configure the partition work manager to impose a minimum threads constraint limit, a partition capacity constraint, and/or a partition maximum threads constraint, all of which restrict the use of thread resources by the partitions within the environment.

Abstract: In accordance with an embodiment, described herein is a system and method for providing administrative command progress status for use with a cloud computing environment. In accordance with an embodiment, a job manager service provides an application program interface which receives administrative commands to be processed within the cloud environment as jobs, wherein each instance of the administrative commands is associated with a unique job identifier. A command line interface allows a user to issue a command to be processed within the cloud environment as a job. During progress of a job associated with an annotated command, a status associated with the progress of the job is determined and provided to the command line interface. For example, the system can provide job progress status during these operations, to reassure the user that the operation is proceeding normally.
