Recovery in Parallel Database Systems - Hvasshovd, Svein-Olaf (Vieweg+Teubner Verlag, 1996)
The relational DBMS technology is a success in the commercial marketplace with respect to busi ness data processing and related applications. This success is a result of cost effective application development combined with high data consistency. The success has led to the use of relational DBMS technology in other application environments requesting its traditional virtues, while at the same time adding new requirements. For example, the integration of relational DBMS technology with telecommunications has led to such combined requirements as transaction rates of more than 10. 000 TPC-B like transactions per second, transaction service availability of certain transaction classes of 99,999%, and transaction response time under 10 milliseconds. The current trends in hardware price/performance and parallel technology make relational DBMSs which support very high transaction rates, very high availability, and soft real-time transaction response a cost effective possibility. This book describes a recovery method supporting the traditional high DBMS data consistency while offering very high transaction rates, continuous availability, and soft real-time transaction response. It also presents high availability approaches used by commercial DBMS products. Acknowledgements The book is based on my doctoral (Dr. Ing. ) thesis. Due to an extreme work load over a long period it has taken some time to complete the book transformation. My Dr. lng. research and the following book transformation period clearly demonstrated to me the value of true and trustful friendship
