This paper proposes an application-transparent, low-overhead checkpointing strategy for maintaining consistency of control structures in a commercial main memory database (MMDB) system, based on the ARMOR (Adaptive Reconfigurable Mobile Object of Reliability) infrastructure. Performance measurements and availability estimates show that the proposed checkpointing scheme significantly enhances database availability (an extra nine in improvement compared with major-recovery-based solutions) while incurring only a small performance overhead (less than 2% in a typical workload of real applications).
