基于传统群件Lotus Domino的分布式解决方案
|
摘要
Lotus Domino是优秀的办公电子协作平台,具有独特的安全特性和快速开发等特征。被广泛运用于政府和企业的办公自动化和邮件系统。但由于使用的是文档型数据库,随着数据量增长,性能会急剧下降;且它的数据库、Web服务器、应用服务器均耦合集成,不易扩展,在大型系统的应用上有很大的局限。随着信息化的发展,政府企业都开始集约化方向发展,希望建立集中式的数据中心。Lotus Domino在大型应用系统上的发展遭遇瓶颈。通过运用分布式的思想对Lotus Domino进行包装改造,建设可扩展的副本和分片机制,建设统一的数据索引中心与调度中,将数据与负载动态平摊于多个Domino服务器节点间。通过国家电网协同办公一级部署系统的运行实践表明,创新的分布式架构让Domino平台充分发挥其优势情况下又规避了它在负载能力上的不足。
Domino Lotus is a good office electronic collaboration platform, with unique security features and rapid development and other characteristics. Widely used in government and enterprise office automation and mail system. But due to the use of document database, with the increase of the amount of data performance will be a sharp decline; and its database, web server,application server are coupled integration, not easy to expand, in the application of large system have great limitations. With the development of information technology, government enterprises are beginning to develop intensive, hoping to establish centralized data center.. The development of Domino Lotus in the large scale application system has encountered the bottleneck. By using the idea of distributed packaging transformation of Lotus Domino, the construction of scalable copy and distribution mechanism, construction of a unified data index center and scheduling, data and dynamic load equally in multiple Domino server nodes. Through the national grid collaborative office level deployment system operation practice shows that, innovative distributed architecture for domino platform give full play to its advantages and avoid the it in the load capacity problems.
