Abstract: Method, computer program product, and computer system are provided. A controller component verifies the state of all file sets. The controller component initiates a sub-controller component, based on successfully verifying the state of the file sets. The sub-controller component suspends write operations to all databases at the primary site computer. Based on the suspending completing without error, the sub-controller executes point-in-time copy processes for each of the databases and for application non-database files at the primary site computer. Applications using the databases and non-database files are not suspended. Based on all of the point-in-time copy processes completing without error, the sub-controller component resumes write operations to all databases at the primary site computer. The point-in-time copies are automatically sent to the secondary site computer so that the applications can operate at the secondary site computer if the primary site computer becomes unavailable.

Abstract: Embodiments include a method for controlling a device, a voice-controlled device, and a computer program product. One embodiment of the method may comprise receiving a first command from a first user at a device and receiving a second command from a second user at the device, and determining, by a first trained machine learning model, that the second command conflicts with the first command. In response to determining the second command conflicts with the first command, some embodiments may determine, by a second trained machine learning model, a physical world hierarchy between the first user and the second user, determine a response to the second command using the physical world hierarchy. The method may further comprise performing the response. Some embodiments may further comprise identifying, by the second trained machine learning model, a higher ranking user chosen from the group consisting of the first user and the second user.

Abstract: A method, computer system, and a computer program product for cognitive application review is provided.
