9417907 Eich This award will partially support travel, living expenses and publication costs for Dr. Margaret H. Eich and a graduate research assistant from Southern Methodist University to conduct cooperative research with Dr. Maria Orlowska and Dr. Robert Colomb, of the Department of Computer Science at the University of Queensland in Brisbane, Australia. The collaborative research will focus on developing new checkpointing and recovery algorithms aimed at distributed databases. Database checkpointing saves the state of a database on a stable memory separate from the primary database copy. In the event of a failure of a primary copy, the loss can be restored using the backup copy of the log. Checkpointing techniques so far examined by the Southern Methodist group require no synchronization between transactions and checkpointing, and also facilitate a partial recovery of the database after failure. These features are desirable for both a high throughput Main Memory Database (MMDB) system, and also for a distributed database environment. Objectives for this cooperative work are to examine techniques for extending MMDB recovery to distributed databases. The specific work to be conducted will apply partition checkpointing to distributed database environments, will expand commit and partial recovery algorithms for distributed environments, and will perform initial analytic studies validating the developed approaches. ***

Eich博士和一位来自南卫理公会大学的研究生研究助理与澳大利亚布里斯班昆士兰大学计算机科学系的Maria Orlowska博士和Robert Colomb博士进行合作研究的旅费、生活费和出版费用。合作研究将侧重于开发针对分布式数据库的新的检查点和恢复算法。数据库检查点将数据库的状态保存在与主数据库副本分离的稳定内存中。在主副本发生故障的情况下，可以使用日志的备份副本恢复损失。到目前为止，Southern Methodist小组研究的检查点技术不需要事务和检查点之间的同步，而且还有助于在失败后恢复数据库的部分。这些特性对于高吞吐量主内存数据库（MMDB）系统和分布式数据库环境都是理想的。这项合作工作的目标是研究将MMDB恢复扩展到分布式数据库的技术。将要进行的具体工作将在分布式数据库环境中应用分区检查点，将扩展分布式环境的提交和部分恢复算法，并将执行验证所开发方法的初步分析研究。＊＊＊
