摘要
数据挖掘技术是一种新的信息处理技术。其目的是从海量数据中抽取潜在的,有价值的数据规律或数据模型。通过数据挖掘技术对高校教学数据的分析处理,能够形成真正有价值的知识,向决策者提供信息支持,有利于推动学校教学改革和建设的全面发展。该文主要针对现行高校实际运作的学分选课数据库系统,以关联规则挖掘为例,提出简单而可行的数据挖掘应用实施办法。
Oracle Real Application Clusters (RAC) has the functions.of loadbalance (LB) and other high-availabilities (HA). This paper showws that Oracle RAC is loadbalance of cpu, not number of sessions[1-2] ,through a large number of experiments on testing and analyzing. loadbalance.Therefore,it is helpful to understand and use the mechanism of loadbalance,and take effective measures to enhance the throughout of system,and play optimum performance of high availability system.
