查询词典 distributed database

It can support the main stream database now, such as SQL Server 2000, Oracle 9i, DB2, and can be distributed on servers running Weblogic, Tomcat, JRun and JBoss. It can satisfy most requirements. The user interface is simple and wieldy through the XML configuration file and "taglib"; it is convenient for developing.

该组件支持SQLServer2000，Oracle9i，DB2等主流数据库，并且可以部署在Weblogic，Tomcat，JRun，JBoss等Web服务器上，能够满足绝大部分开发要求；该组件的接口简单易用，主要是以XML配置文件和taglib的形式体现，方便二次开发。

This paper's work is trying to present a more efficient method to locate the agent in distributed networks on the basis of pioneers' researches, and assess the performance of this method.This paper begins its discussion with agent technology's background and basic conceptions, characteristics, and presents the researched problem, that is, researching new agent locating method; then introduces several traditional locating methods: brute force searching, database method and path proxies, and analyses their features and locating efficiency. For describing the agent locating better, this paper formalizes the agent, presents a proper definition, and abstracts agent's migration process, proposes a metaprocess concept and decompounds migration process with it.

本文首先介绍了代理技术的产生背景以及基本概念、性质，提出了需要解决的问题，即对新的代理定位的方法的研究；然后总结介绍了前人文献中的一些代理定位方法：穷举搜索法、位置数据库法和迁移指针法，并分析了这些算法的优缺点和代理定位效率；为了更准确的描述代理定位，本文对代理进行了形式化，确定了一种适合的代理定义，并对它的性质给予形式说明；在此基础上抽象出代理迁移的本质，根据它对资源的控制对迁移类型进行分类；提出元过程概念，并分解表示定位过程，并介绍了过程时间连续性。
