    • In the case of performance deterioration or performance excess with respect to current resource assignment, both processing capacity and resource use efficiency are optimized by an appropriate configuration change. For that purpose, the present invention proposes an appropriate migration measure to a request for performance improvement. Whether or not the server in which performance deterioration or excess occurs and another server influence each other in performance is identified, and it is determined whether a change of a resource amount in the same device is appropriate or migration to another device is appropriate. Regarding the migration measure, after feasibility is checked, items for improvement are presented together with required time and cost taken for the migration, and merits and demerits of the configuration change work are quantitatively indicated (see Fig. 4).
    • 在针对当前资源分配的性能恶化或性能过剩的情况下,通过适当的配置更改优化处理能力和资源使用效率。 为此,本发明提出了对性能改进请求的适当的迁移措施。 识别性能恶化或过多发生的服务器和另一个服务器在性能上的影响,确定同一设备中的资源量的变化是否合适,或者对其他设备的迁移是否合适。 关于迁移措施,检查可行性后,提出改进的项目以及迁移所需的时间和成本,定量指出配置变更工作的优缺点(见图4)。
