Abstract: Systems, methods and computer program products for controlling access to an organization's data in a multitenant environment are provided. An organization hierarchy is defined at a multitenant platform, the organization hierarchy comprising an organization and a plurality of sites owned by the organization, each of the plurality of sites representing a data isolation boundary for the organization's data. The sites are associated with subscriptions to applications of the multitenant platform. The organization can designate user partitions within the sites, each user partition designating a corresponding set of site users and a corresponding authentication service. The multitenant platform enables access to each subscription of a site only if a site user is authenticated by the authentication service designated in the user partition corresponding to the site user.

Abstract: Systems and methods for secure database schema migration are described. In an illustrative, non-limiting embodiment, an Information Handling System (IHS) may include: a processor and a memory, the memory having program instructions that cause the processor to: calculate a first hash of schema objects for a database; compare the calculated first hash of the schema objects with an expected second hash of the schema objects for the database; determine that the schema objects comprise a previous version of the database; and execute scripts to upgrade the schema objects for the database. The program instructions can also cause the processor to: determine that the calculated first hash of the schema objects does not compare with the expected second hash of the schema objects, and determine that the calculated first hash of the schema objects compares with a third hash of the schema objects corresponding to the previous version of the database.

Abstract: A linear electromechanical actuator with a failsafe design may be used with a downhole flow control system. In one example, a subsurface safety valve for controlling flow of production fluids includes a valve closure element moveable between an open position and a closed position in response to a linear movement of an actuating member. A biasing member biases the valve closure element to the closed position. A power section with an electrically-powered motor drives a rotation. A drive section coupled to the power section converts the rotation of the motor to the linear movement of the actuating member to at least open the subsurface safety valve. A clutch selectively decouples the power section from the drive section in response to a power loss.
