Abstract :
The goal of checkpointing in database management systems is to save database states on a separate secure device so that the database can be recovered when errors and failures occur. Recently, the possibility of having a centralized checkpointing mechanism that does not interfere with the transaction processing has been studied. Users are allowed to submit transactions while the checkpointing is in progress, and the transactions are performed in the system concurrently with the checkpointing process. This property of noninterference is highly desirable to real-time applications, where restricting transaction activity during the checkpointing operation is in many cases not feasible. The author presents a decentralized algorithm for noninterfering checkpointing in distributed database systems.<>
