    摘要: Mechanisms are provided for performing a failover operation of an application from a faulty node of a high availability cluster to a selected target node. The mechanisms receive a notification of an imminent failure of the faulty node. The mechanisms further receive health information from nodes of a local failover scope of a failover policy associated with the faulty node. Moreover, the mechanisms dynamically modify the failover policy based on the health information from the nodes of the local failover scope and select a node from the modified failover policy as a target node for failover of an application running on the faulty node to the target node. Additionally, the mechanisms perform failover of the application to the target node based on the selection of the node from the modified failover policy.

    摘要: The state of data of a communications environment is automatically managed. The automatic management is provided via a facility that automatically obtains the current state of the data and uses that information to place the data in an appropriate state for a selected event to be processed. The data is, for instance, maintained on replicated storage media.

    摘要: A system and method for establishing a passive recovery environment for an operating system kernel. A cross reference between an instruction address range and recovery routine address is established during binding of the kernel. Normal process initiation and termination includes no recovery overhead. In the case of system failure, the failing instruction address is used to access the recovery routine cross reference tables to determine recovery routine address. The error detection process then initiates recovery routine processing.

    摘要: A method for communicating node liveness in a multinode data processing system employs an operating system function that provides a degree of self-awareness in “sensing” an imminent but still pending failure as the basis for providing special flag signals over a channel which employs nonvolatile storage in a heartbeat signaling path.
