In the case of a " gold standard " two identical cells domains , a highly available database can pretty much assure session failover between domains , while with memory to memory , there can only be a single replicator common to the two cells ; hence , it becomes a single point of failure spof 对于“黄金标准” (两个相同的单元/域) ,高可用性的数据库完全可以确保两个域之间的会话故障转移,而对于内存到内存复制,两个单元只能有一个通用复制器;因此,它就变为单点故障( spof ) 。
Configuration settings for the domino 6 . 5 and domino 7 tests were similar , with the main difference being that with domino 7 , we could reduce the number of cluster replicator tasks from eight to six , and still meet the benchmark goal of keeping the average cluster replication queue time under 15 minutes Domino 6 . 5和domino 7测试的配置设置很相似,最大的不同是对于domino 7 ,可以将集群复制器任务数目从8减小为6 ,这样仍然可以达到保持平均集群复制队列时间在15分钟以内的基准测试目标。
Firstly , we introduced the main idea , the formalized description , and the basic flow of co - evolution algorithm . then , from the point of pattern analyzation , we established the mathematics model of the multi - population co - evolution algorithm based on pattern replicator equation of the single population genetic algorithm , and made the theoretical analysis and compare for the method of best choice and the method of random choice of the co - evolution algorithm . we put forward a new method for the individual fitness evaluation , and validated the performance of the new method by the simulation experiment 首先,在介绍了协进化算法的核心思想、形式化描述和基本算法流程的基础上,从模式分析角度出发,建立了基于模式复制方程的多群体协进化算法数学模型,对协进化算法中的最优选择法和随机选择法进行了理论分析与比较,提出了一种新的个体适应度评价方法,并通过仿真实验验证了新方法的效率。
