Abstract:
A parallel-processing apparatus and method provide for synchronous replication in a database management system (DBMS). During synchronous replication into the active node and the standby node in the DBMS, replications of transactions are parallelized in units of transactions, thereby improving a performance of the DBMS, guaranteeing atomicity and consistency of the transaction, and solving the deadlock state which may occur in parallel-processing.
