【摘要】 由于性能和其他要求,存在一类特殊的应用,它们要求大批量数据常驻内存,并直接在内存中对数据进行存取访问,增加内存中产生脏数据的可能性。该文对内存中的脏数据进行了分类,并结合传统数据库的日志技术和检查点技术,给出了脏数据的预防、静态检测和恢复的基本方法。该方法在移动计费系统中得到了应用。更多还原

【Abstract】 For better performance and other purposes, some special applications have direct access to data which resides in the main memory, as a result of which, the risk of data being corrupted due to application default is increased. In this paper, data corruption in main-memory data management is discussed. Also presented is a practical method for detecting and recovering data corruption based on log, which has been used in the telecom accounting application system.更多还原
