Abstract

While speculatively executing a given one of a plurality of transactions concurrently executing on a computer, carry out write operations in a local data block, and automatically create an entry in a checkpoint log when reading from a shared memory. Continuously conflict check during read and tentative commit operations, and carry out a partial rollback upon detection of a conflict. The partial rollback is based upon the checkpoint log.
