Abstract: Techniques are disclosed for enabling tenant hierarchy information to be migrated directly between different multi-tenant system (e.g., from a shared IDM system to a Nimbula system, or vice versa). A corresponding new tenant is created in a Nimbula system based on a combination of the tenant information and the service information from the shared IDM system. The Nimbula system extracts the tenant name and the service name from a request and asks the shared IDM system to verify that the user actually is a member of the tenant identified by the extracted tenant name. Upon successful authentication of the user, the Nimbula system requests the IDM system for roles that are associated with both the user and the extracted service name. The Nimbula system enable access to the service upon determining whether the requested operation can be performed relative to the specified service based on the roles.

Abstract: A system and method for providing whitelist functionality for use with a cloud computing environment. In accordance with an embodiment, software applications being deployed to the cloud are restricted from using certain classes or application program interfaces (APIs). During provisioning by, e.g., a Java cloud services (JCS) infrastructure, or another component of the cloud environment, an application's resources, such as its classes or API calls, can be matched against a whitelist of acceptable resources. If the application fails to be validated against the whitelist, it will not be deployed to the cloud, and the customer/user notified accordingly. In accordance with an embodiment, a whitelist functionality can be packaged within a software development kit (SDK), which customers/users can use during development of their applications, to verify that the applications will comply with, or successfully validate against the whitelist, prior to attempting to deploy the applications to the cloud.

The configuration script can define a plurality of nodes to be deployed in the cloud-based storage service. The method can further include parsing the configuration script to identify configuration data for the plurality of nodes, and automatically installing each node in the plurality of nodes based on the configuration data, and, in response to a deployment instruction, deploying the plurality of nodes in the cloud-based storage service.

Abstract: A method and system for managing access to information stored in a data storage system of an organization is provided. In an embodiment, the data storage system may be configured to receive a request from a requester on a client device to access information stored in the data storage system. In some aspects, upon receiving the request, the first system may determine that an access token identifying the requester is stored in a cache in the data storage system. In some aspects, the data storage system may then retrieve one or more roles from the cache. In some examples, the roles may be associated with the access token. In certain embodiments, the data storage system may then be configured to determine that the requester is authorized to access the information based on the roles and provide the information to the requester on the client device.

Abstract: A system and method can support using a data source to connect an application server with a clustered database. The clustered database includes a plurality of database instances and is associated with a notification service. The notification service can be used by the clustered database to broadcast notifications that describe a state change in the plurality of database instances. The data source includes a connection pool, which manages a set of connections to the plurality of database instances in the clustered database. The data source operates to register with the notification service to receive notifications on the change of the clustered database, wherein the application server operates to configure and manage connection to the clustered database, adaptively according to the state change of the clustered database at run time.

Abstract: A clustered database environment includes multiple database instances that appear as one server. An application server can use a data source and connection pools to connect with the clustered database. A notification service broadcasts notifications describing state changes in the database instances, which are then used by the data source and connection pools to control access to the database instances. A data source configuration allows for specification of a preferred affinity policy. A session affinity policy is used to provide database instance affinity for database access made under the context of a web session, whereby database operations are directed to a particular instance for a period of time when the application may be performing multiple, related updates to a specific data set. Directing such operations to a single database instance can be used to improve application performance due to increased local cache utilization.

Abstract: A system and method can support one-way Remote Method Invocation (RMI) session replication in a middleware machine environment, such as a server cluster. The server cluster can include a primary application server and a secondary application server. The primary application server receives a request with a session from a client, maintain the session information, and replicate the session information to a secondary application server using one-way Remote Method Invocation (RMI). The primary application server can then respond to the client based on the session information after receiving a return message of the one-way RMI from a network socket associate with the primary application server. The benefit of using one-way RMI is that the primary application server does not have to wait for an acknowledgment from the secondary application server instance, since the underlying transport protocol guarantees that the session data has been successfully transmitted to the second server instance.
