  • Patent number: 5630124
    Abstract: In parallel database management systems, database update requests typically result in activity at several nodes. Rollback of all updates is required if the update of any node fails. A coordination process monitors for failure or success of updates. The coordinator further provides for distinguishing activities that have taken place at any given node from the other nodes for different database update requests. Savepoints are local. This allows rollback of a selected update without affecting nodes which did not process the update.
