A networked computing system comprises a backup node cluster of a backup service in communication with a host database node cluster of a host, a host database at least initially undiscovered by the backup node cluster, one or more processors coupled with memory storing instructions that, when executed, perform operations comprising at least installing a backup agent on at least one node of the host database node cluster, registering the host at the backup service, based on the host registration, triggering a host database discovery process to discover the undiscovered database automatically, the discovery process including a discovery call, in response to the discovery call, receiving metadata relating to the discovered database, and communicating with the discovered database.

A computing system providing high-availability access to computing resources includes: a plurality of interfaces; a plurality of sets of computing resources, each of the sets of computing resources including a plurality of computing resources; and at least three switches, each of the switches being connected to a corresponding one of the interfaces via a host link and being connected to a corresponding one of the sets of computing resources via a plurality of resource connections, each of the switches being configured such that data traffic is distributed to remaining ones of the switches through a plurality of cross-connections between the switches if one of the switches fails.

A provisional page to be filled with data is allocated in an in-memory database system in which pages are loaded into memory and having associated physical disk storage a provisional page to be filled with data. Thereafter, the provisional page is filled with data. The provisional page is register after the provisional page has been filled with data such that consistent changes in the database are not required for the provisional page prior to the registering.

A system may include a registration module to register the system with a server cluster and a resource collector module operatively connected to the registration module, the resource collector module to identify a list of resources for a container running on the server cluster. The system may also include a resource monitor module operatively connected to the resource collector module, the resource collector module to receive the list of resources for the container, monitor a resource in the list of resources for the container, and generate an event for the container and an event manager module operatively connected to the resource monitor module, the event manager to receive the event and determine a recovery action for the container.

According to aspects of the present disclosure, systems and methods can be provided to recover from memory errors that occur during or following a virtual machine migration. Methods, computer program products and/or systems are provided for handling memory error that perform the following operations: (i) obtaining a memory address that triggered an uncorrected error on a first host associated with a virtual machine migration; (ii) computing a page associated with the memory address; (iii) determining if a copy of the page associated with the memory address is available on a second host associated with the virtual machine migration; (iv) obtaining data from the copy of the page on the second host; and (v) generating a new page on the first host with the data obtained from the second host.

Aspects of the disclosure provide for reducing service disruptions in a computer system. A method of the disclosure may include identifying a plurality of services running on a node of a computer system, determining a plurality of priorities corresponding to the plurality of services, determining a plurality of service capacity factors for the plurality of services in view of the plurality of priorities, and determining a lost impact factor in view of the plurality of service capacity factors.

A vehicle communication system includes a switching hub incorporated in a vehicle and including a switch IC and an external CPU. The switch IC includes an internal CPU and performs a transfer process of transferring information to a communication device. The external CPU is provided outside the switch IC and connected to the switch IC, and has higher information processing capability than the internal CPU. The external CPU can perform a transfer order process of ordering to transfer information to the communication device and perform a security process of securing the security of the information to be transferred when the transfer order process is performed. The internal CPU monitors the operation of the external CPU and when the external CPU is abnormal, performs the transfer order process instead of the external CPU.

A method includes receiving a plurality of data processing requests and generating a primary processing stack indicating a queue for processing the first data. The primary processing stack comprises a plurality of layers. Each layer comprises a plurality of slices, wherein each slice represents a portion of the first data of at least one data processing request. The plurality of slices are arranged within each layer based at least on the priority indicator corresponding to the first data that each slice represents. The method further includes receiving resource information about a plurality of servers, assigning each slice of the primary processing stack to one of the servers, and sending processing instructions comprising an identification of each slice of the primary processing stack assigned to the respective server.

This application provides a resource pool management method and apparatus, a resource pool control unit, and a communications device. The method is applied to a resource pool system including a plurality of communications devices, and one resource pool control unit is deployed on each communications device. A first resource pool control unit that is responsible for managing a resource pool at a current moment receives a resource application request of an application program on any communications device, allocates, from the resource pool according to a preset rule, a first resource including one or more logical hardware devices, and sends a resource configuration request to a second resource pool control unit, so that the second resource pool control unit completes configuration of the first resource based on the resource configuration request, to provide a required hardware device resource for the application program.

Described is a system, method, and computer program product for performing elections in a database cluster, where system resource statistics information is used to predict a cluster node failure. Resource statistics data is classified and used to identify anomalies. The anomalies can be used to determine the probability of a cluster node failure and to then elect a new master node and/or surviving sub-cluster.
