Reducing internal retention time of processing requests on a web system having different types of data processing structures

摘要

An information processing apparatus calculates parameters corresponding to the data processing structure of a web system. An extraction unit 22 extracts, from operation data of a web system having capacity control parameters including a maximum queue length indicating the maximum size of a queue which temporarily stores request data and the maximum number of simultaneous executions indicating the maximum number of times the request data can be processed in parallel, an internal retention time required for the web system to process data in each number of internal retention requests which is the sum of the number of uses of the queue and the number of times the request data is processed in parallel. A coefficient calculation unit 23 applies an approximate equation corresponding to the data processing structure of the web system to the internal retention time in the number of internal retention requests extracted by the extraction unit 22 to calculate coefficients of the approximate equation. A parameter calculation unit 24 calculates new capacity control parameters from the approximate equation calculated by the coefficient calculation unit 23.

1. An information processing apparatus for reducing internal retention time of processing requests on a web system comprising:
an extraction unit executed by a processor that extracts, from operation data of the web system having capacity control parameters including a maximum queue length indicating a maximum size of a queue which temporarily stores the processing requests and a maximum number of simultaneous executions indicating the maximum number of the processing requests that can be processed in parallel, an internal retention time required for the web system to process data for each of different numbers of internal retention requests wherein the number of internal retention requests is a sum of the queue length and the number of simultaneous executions, and wherein the internal retention time includes only processing time of the processing requests that is controlled by the capacity control parameters; a coefficient calculation unit executed by the processor that applies an approximate equation to the internal retention time for each of the different number of internal retention requests extracted by the extraction unit to calculate coefficients of the approximate equation by regression analysis, the approximate equation corresponding to a particular data processing structure of the web system; a parameter calculation unit executed by the processor that calculates new capacity control parameters including the maximum number of simultaneous executions and the maximum queue length, at which the internal retention time at different amounts of load of the web system is minimized, from the approximate equation having the coefficients calculated by the coefficient calculation unit; and a transmitting unit executed by the processor that transmits the new capacity control parameters calculated by the parameter calculation unit to the web system, wherein the web system executes the processing requests with the new capacity control parameters.
