Abstract: Disclosed are systems, software, and methods for providing event-based notifications to client devices. One system for such includes memory storing computer program instructions and one or more processors configured to execute the computer program instructions. The instructions cause operations that include receiving, at a gateway service module from an event-originating application, an event data packet comprising event information about an event. The gateway service module provides event information to an event-processing module. The event-processing module generates an event notification based at least on the event information. The gateway service module initiates a push notification to a client device that includes the event notification and instructions to display the event notification at the client device.

Abstract: A first cluster creates a cluster exchange object including identifiers of components of the first cluster and segments of data of the first cluster along with configuration data, such as access points and credentials. The first cluster transmits the object to a second cluster that instantiates copies of the components and retrieves the segments from the first cluster to become a replica of the second cluster. The second cluster may then commence execution upon failure of the primary cluster and restore the primary cluster. The primary cluster may send snapshot objects to the second cluster to communicate changes to the primary cluster and the snapshot objects may also be used to restore the primary cluster following failure. The components of a cluster may be represented in a directory structure and data describing a component may be retrieved in response to user interactions with a representation of the directory structure.

Abstract: Embodiments herein described techniques for calling an OS service to resolve a storage access exception in OS memory space. To do so, the hardware can use an exception indicator to indicate when an access exception has been detected and then the application program can use the exception indicator to instruct an OS service to resolve the exception on behalf of the application program. In one embodiment, the exception occurs when performing an interruptible instruction issued by the application program where the instruction is performed at different times. When executing the counter update step of the interruptible instruction, the hardware can determine whether an exception is detected, and if so, update an exception indicator. The application program calls the OS service which resolves the access exception in OS memory space on application program's behalf.

Abstract: A hardware reconfiguration system for first and second devices is in a lock-step configuration using a comparator that provides a lock-step error indication. The system includes at least one register that stores a lock-step threshold. The system also includes a lock-step monitor configured to compare a count of occurrences of the lock-step error indication from the comparator with the lock-step threshold. When the lock-step threshold is reached, the lock-step monitor is configured to enter a repair state to determine which one of the first and second devices is operating correctly and reconfigure operation into a split-lock mode to resume operation using the one of the first and second devices that is operating correctly.

Abstract: From a first usage data relating to a behavior of an app during an execution on a first device, a feature related to the behavior is extracted. Based on the feature, the first usage data is clustered into a cluster with a second usage data from a second device. Resolution data related to the feature is obtained; the resolution data includes at least a state of development of code related to the behavior. By the first usage data and the resolution data as inputs to a trained prediction model, a likelihood of a crash of the app on the first device is predicted as a score. The score and the state of development of the code are output to the first device.

Abstract: One or more techniques and/or computing devices are provided for resynchronization. For example, a request may be received to create pseudo snapshots of a first consistency group, hosted by a first storage controller, and a second consistency group, hosted by a second storage controller, having a synchronous replication relationship with the first consistency group. Incoming client write requests are logged within an intercept tracking log at the first storage controller. After a first drain without hold of incoming write requests is performed, a first pseudo common snapshot of the second consistency group is created. After a second drain without hold of incoming write operations is performed, a second pseudo common snapshot of the first consistency group and the intercept tracking log is created. The pseudo snapshots and the intercept tracking log (e.g., indicating a delta between the pseudo snapshots) are used to resynchronize the first and second consistency groups.

Abstract: A method and system to increase system availability during a fault of a non-safety target is disclosed. A fault signal is received indicative of a response to a request from an initiator not being received from one of a safety target and non-safety target within a response time. Based on the response not being received from the non-safety target, only the non-safety target is reset to increase the system availability rather than also resetting safety targets. Because a target did not respond to the request, a dummy responder further sends to the initiator a response to the request to prevent the initiator from entering into a hang state.

Abstract: Methods and systems for managing data processing systems are disclosed. A data processing system may include and depend on the operation of hardware and/or software components. To manage the operation of the data processing system, a data processing system manager may obtain logs for components of the data processing system. Inference models may be implemented to predict likely future component failures (e.g., failure sequences) and their associated times-to-failures using information recorded in the logs. The failure sequences may be presented as an acyclic graph that associates component failures, their times-to-failure, and related actions. The probable failure sequences may be analyzed to identify sets of actions. The sets of actions may be optimized based on deviations detected during executing the sets of actions to optimize operational goals (e.g., maximizing system lifetime, minimizing system costs), and/or reduce the likelihood of the data processing system becoming impaired.
