  • Method and system for automatic failover of distributed query processing using distributed shared memory
    Patent number: 8874961
    Abstract: A method and system for implementing automatic recovery from failure of resources in a grid-based distributed database is provided. The method includes determining the category of each node in the subgroup of nodes, where the determination identifies each node as at least one of a worker node and an idle node. The method further includes saving state of each worker node engaged in execution of a task in a shared memory at pre-determined time intervals. Each worker node is monitored by one or more idle nodes in each sub-group. Upon detection of no change in state of worker node for a pre-determined period of time, a failure notification is raised by one or more idle nodes that have detected failure of the worker node.
