    • A resource usage analysis tool (23) calculates a number-of-requests variation parameter indicating the variation of the number of processed requests and a resource variation parameter indicating the usage rate and/or variation of the usage amount of the resource of the computer system from a request classification log (31) in which the number of requests processed by the computer system in each measurement period is described and system logs (32 to 34) in which the usage of the resource of the computer system in each of the measurement periods is described. An asynchronous processing detecting module (51) detects at least one occurrence of a post-processing which is a processing to be performed after the return of a response in order for the computer system to process the requests and an unexpected processing which is a processing to be performed independently of the processing of the requests but not to be performed routinely from the number-of-requests variation parameter and the resource variation parameter.

    • A system utilization rate managing device that realizes a management of a system performance and an optimization of the number of operating nodes of different performances and architectures is provided. A node maximum-performance setter of a processing device files a maximum performance of each node constituting an external system into a node maximum-performance memory section of a memory device. A resource utilization rate acquirer acquires a resource utilization rate of each node, and gives it to a virtual utilization rate calculation section. The virtual utilization rate calculation section calculates a virtual utilization rate of the system from the maximum performance of each node retained in a node maximum-performance memory section and the resource utilization rate of each node, and gives the virtual utilization rate to an output section. The output section outputs the virtual utilization rate to an output device.
    • 提供了实现系统性能管理和不同性能和架构的操作节点数量优化的系统利用率管理设备。 处理设备的节点最大性能设置器将构成外部系统的每个节点的最大性能写入存储器设备的节点最大性能存储器部分。 资源利用率获取器获取每个节点的资源利用率,并将其提供给虚拟利用率计算部。 虚拟利用率计算部根据节点最大性能存储部中保存的各节点的最大性能和各节点的资源利用率来计算系统的虚拟利用率,并将虚拟利用率提供给输出部。 输出部分将虚拟利用率输出到输出设备。

    • A data grouping means divides data items stored in a cache memory section into groups of data having different access patterns. The priority assigning means assigns an order of priorities to data items in each group that the priority assigning means manages according to an individual caching algorithm. The lowest priority determining means determines the lowest priority group when there is not enough unused memory space in the cache memory section and it is necessary to purge a data item. The data operating means purges the lowest priority data in the lowest priority group. Thus the groups of data having different access patterns can be cached effectively.
    • 数据分组装置将存储在高速缓冲存储器部分中的数据项划分成具有不同访问模式的数据组。 优先级分配装置根据各个缓存算法,对优先级分配装置管理的各组中的数据项分配优先顺序。 当高速缓冲存储器部分中没有足够的未使用的存储器空间并且需要清除数据项时,最低优先级确定装置确定最低优先级组。 数据操作装置清除最低优先级组中的最低优先级数据。 因此,可以有效地缓存具有不同访问模式的数据组。
