中文摘要: 传统的磁盘数据库由于I/O 瓶颈的限制，愈来愈不能满足实时高性能应用的需求。内存数据库由于能够提供更快的响应速度和更大的事务吞吐量，在电信领域得到愈来愈多的应用。在对内存数据库技术进行研究的基础上，首次将内存数据库应用到彩铃业务中，提出一种改进的彩铃业务数据库结构。测试结果表明，引入内存数据库之后，彩铃应用的性能得到有效提高，并且CPU 占用降低，系统能够承载更多的用户。
Abstract:Because of the I/O bottleneck, the conventional disk resident database (DRDB) system becomes more and more unsuitable for the needs of real-time high-performance applications. Providing much better response time and transaction throughput as compared to DRDB’s, the main memory resident database (MMDB) system has been more and more widely used in telecom field. In this paper, after studying the MMDB technology, we propose a modified database structure in Color Ring Back Tone (CRBT) service, using MMDB in CRBT service for the first time. Test results show that the performance of CRBT application has been efficiently improved by using MMDB and the CPU utilization has been decreased, which means the system’s capacity of users has been enlarged.
