If a number of users request synchronous http handlers that rely on external processes , the operating system can quickly run out of threads because many threads are blocked and waiting for an external process 如果许多用户都在请求依赖于外部进程的同步http处理程序,那么操作系统可能很快就会用完所有线程,因为大量线程被阻止,正在等待外部进程。
The research results is briefed as follow . ( 1 ) a new communication and decision - making method is presented , which integrated several new tools as well as some old ones ; ( 2 ) a new concept of " virtual communicating place shared in real time by multi - user " is brought forward , and a new technology based on event - driving and message - transferring mechanism is designed to realize graphic data shared by multi - user and displayed synchronously under net environment , which is the basis of the whole system . ( 3 ) a new mechanism for team members to share data efficiently is devised , which supports collaborative working in progress , maintains the consistency of data , records the history of design and etc . by defining a new type of the design data attributes and the privilege of team member to access to data in different time , using a new method of data manipulating , the team data sharing is realized 本文的主要研究成果为: ( 1 )在研究国内外网络决策交流方式方法的基础上,综合多种方法的优点,提出了一种新的决策交流方式,采用了多种手段和工具,完善了网络决策交流的机制; ( 2 )提出了多用户共享的可视化虚拟交流空间的概念,并对其实现技术进行仔细的分析,针对目前存在的技术难点,提出了可行的解决方案,设计了一种新型的基于事件驱动和消息传递机制的多用户实时共享图形数据的解决方案,并采用了跨平台的java技术实现了网络环境下图形数据的实时交流和显示; ( 3 )针对团队协同的网络cad系统的特点和要求,提出了一种新的团队数据共享机制,通过对产品数据的基本属性、历史属性、共享状态属性和关联属性的定义,结合对团队成员在不同设计阶段的权限控制,采用新型的对共享数据库的数据操作方法,动态地维护团队数据的共享、设计的变更、设计进程的同步、关连数据的一致性、以及多个团队之间的数据交流。
