基于CORBA的海量数据加载并行任务调度技术研究与实现

DESIGN AND IMPLEMENTATION OF PARALLEL-JOB SCHEDULING IN CORBA-BASED MASSIVE DATA LOADING

基于多集群的并行任务调度技术,简要描述在使用Oracle10g进行海量数据加载中的并行任务调度问题,设计实现了一个基于CORBA的海量信息加载服务中的并行任务调度算法。通过测试结果表明,在适当的任务并行度的前提下,采取并行任务调度算法的加载服务的数据加载能力要优于传统的加载服务。

Based on techniques of parallel task assigning in the multi-cluster system, this paper briefly discusses such problems in the case of CORBA-Based massive data loading supported by Oracle 10g. It first designs and implements algorithms for parallel task assigning in CORBA-Based massive data loading service. And then it＇s indicated by the result of extensive experimental that in the precondition of the proper task parallel levels, adopting the algorithm of parallel task assigning is more excellent than the traditional ones.
