Patent number: 9319284Abstract: A delay in a configuration changing operation of a computer system including a manual procedure and an automatic procedure is detected. Based on actions of a setup tool or a configuration tool operated on IT resources, an event which occurs corresponding to the start and the end of a manual procedure is detected and the actual time of the manual procedure is calculated from the detection time points. Next, a delay rate is calculated from a scheduled time and the actual time of the manual procedure, and an end time point of an incomplete operation procedure is estimated from an estimated time required for the manual procedure with the calculated delay rate taken into account and from a time required for the automatic procedure to determine whether the scheduled operation will be finished within a period.Type: GrantFiled: August 31, 2010Date of Patent: April 19, 2016Assignee: HITACHI, LTD.Inventors: Daisuke Iizuka, Takuya Oda
