  Abstract

Database management systems(DBMS) using volatile memory should have a recovery function to protect data against system failures. Recovery requires much overhead in transaction processing and is one of the great factors that deteriorate the system performance. Recently, there have been a lot of studies on database systems with nonvolatile memory to enhance the performance. A nonvolatile memory called DFeRAM is one of the promising memory devices of the future technology, but this device does not support fine-granularity locking. In this paper, we present a dual plane FeRAM(DFeRAM) architecture to support the fine-granularity locking. We also propose a recovery algorithm for the database system with the DFeRAM based on a shadow paging method. In order to analyze the performance of the proposed algorithm, we present an analytical model and analyze the performance using the model.
