A method, system, and medium are disclosed for performing failover data replication with colocation of session state data. In servicing a client request, a first session is created on a primary server. A first portion of session data comprises a state of the first session and is stored on the primary server. An identifier of the first session is stored on the primary server. One or more backup servers are selected for backup of the first portion of session data. A second session is created on the primary server. A second portion of session data comprises a state of the second session and is stored on the primary server. The same backup server(s) are selected for backup of the second portion based on the stored identifier of the first session. The primary server replicates the first and second portions of session data into memory space of the backup servers.

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.

A method and associated systems for automated deployment of a private modular cloud-computing environment. A processor receives and analyzes user requirements, then uses those requirements to select and optimize module packages that direct automatic installations & configurations of modules of the private modular cloud-computing environment. These packages provide resources and instructions that let the processor first validate a base computing platform as being able to physically support desired virtualized cloud platform and services, then automatically install and configure the cloud's virtualization layer, cloud-management stack, virtual infrastructure, cloud services, applications, middleware, and other components onto the base platform. The processor analyzes and confirms the success of each deployment step of each module package as the step is performed. Module packages may be saved, revised, and reused to identify, update, duplicate, or optimize modules of the deployed cloud platform.

Automated deployment of a private modular cloud-computing environment

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.

Described herein are systems and methods for integrating a database into a cloud computing environment. In accordance with an embodiment, a system includes a service management engine (SME) configured to execute in the cloud environment and to access a provider type including coordinates to a database and authentication information for the database. When a service deployed to the cloud environment requests use of a database, the provider type can trigger creation of the database and a schema for use by the associated provider. In accordance with an embodiment, the provider type can include coordinates to a container database (CDB) and authentication information for the CDB. When a service deployed in the cloud environment requests a database, the provider type can trigger creation, via the CDB, of a pluggable database (PDB), with a schema for use by the service.

A method, system, and medium are disclosed for performing transparent failover in a cluster server system. The cluster includes a plurality of servers. In servicing a client request, a primary server replicates session data for the client into memory space of one or more backup servers. The primary server sends a response to the client, wherein the response includes an indication of the one or more backup servers. When the client sends a subsequent request, it includes an indication of the backup servers. If the primary server is unavailable, the cluster determines a recovery server from among the backup servers indicated by the request. The chosen recovery server would then service the request.

Failover Data Replication to a Preferred List of Instances

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.

A system and method for providing service definition packages for use with a cloud computing environment. In accordance with an embodiment, a cloud platform enables provisioning of enterprise software applications (e.g., Fusion Middleware applications) within a cloud environment. In an embodiment, enterprise applications can be packaged as service definition packages (SDP). Each SDP can include an application binary component, a metadata defining the application's service characteristics and requirements, and a plugin that enables the SDP to be installed into the cloud platform. The SDP can also include a virtual assembly that defines a topology and configuration for a set of virtual appliances. The application, as defined by its SDP, can be instantiated as one or more services that are then accessible by other (e.g., customer) applications within the cloud environment.

System and method for service definition packages for use with a cloud computing environment

In accordance with an embodiment, described herein is a system and method for providing service resources for consumption by an application deployed to a service in a cloud environment. A service definition package (SDP) for the service can specify a dependency on a provider, and include association rules that define actions to be taken with regard to a runtime of the provider. When the service is provisioned, a service resource type which is derived from a provider SDP can be associated with the service. As a result of the association, a service resource can be automatically created from the service resource type in accordance with the association rules, to provide resources for consumption by the application. In accordance with an embodiment, the provider SDP can include a plurality of feature sets associated with different sets of configurable properties, which allows different provider types or service resource types to be created.
