摘要： A method of transferring a transaction workload of a primary process pair. The primary pair has access to a stable storage volume for storing data items and a log for storing transaction processing updates to data items. A backup process pair is established for the primary pair and information is transferred thereto so that it can take over for the primary pair should that pair fail. Additionally, a lock table is maintained and update records are written to the log by the primary pair. The update records include any locks from the lock table that related to the update records. When a failure of the primary pair occurs, the storage volume is locked, and the backup pair reads the log to reconstruct a lock table. Once the locks have been reconstructed, the lock on the storage volume is released and the backup pair operates to process the workload.

摘要： A method of processing a transaction includes processing a transaction workload in a primary process pair on a first node in a cluster of nodes, the processing using at least one stable storage volume for storing a database and another stable storage volume for storing a log, the at least one stable storage volume and the log storage volume forming a log storage group. The method further includes performing checkpointing operations via the network from the primary process pair to a backup process pair while processing the transaction workload, the backup process pair operating on a second node in the cluster of nodes. The method further includes detecting a failure making the first node inoperable or inaccessible, and after detecting the failure, engaging the backup process pair to take over the transaction processing workload of the primary process pair, the backup process pair being configured to operate with the log storage group used by the primary process pair on the failed node.
