Methods, systems and computer program products for kernel based transaction processing

摘要

Methods, systems and computer program products are provided for transferring a Transmission Control Protocol (TCP) connection with a client device between data processing systems in a cluster of data processing systems. An operating system kernel of a first data processing system obtains application level information from a transaction received from the client over the connection. In addition, application state information associated with the connection may be obtained from the first application. A second application at a second data processing system is selected for transfer of the connection based on the obtained information and the connection is transferred to the second data processing system. The transfer includes providing to the second data processing system the associated state information of the first communication protocol stack and, optionally, the obtained application state information associated with the connection from the first application. Selection operations for transfers may be initiated responsive to a notification from the first application of completion of a transaction.
