Recovery in a shared disk parallel database system using DFeRAM
Yong Keol Kim, Young Sik Baek, Seong II Jin, Sung-Hyun Cho · 2002
A nonvolatile memory called FeRAM (Ferroelectronic Random Access Memory) is one of the promising memory devices. This paper presents a dual plane FeRAM (DFeRAM) architecture for recovery in the shared disk parallel database system. This paper also presents a recovery algorithm based on a shadow paging method using a DFeRAM architecture. We compare the performance of the log based method and that of our method based on simulation results, which show that our method is better than the log based method when both methods use a nonvolatile memory.
