In performance estimation when the configuration of a computer system is changed, the influence, on performance, of a temporary increase in load to a computer system due to reallocation of a process request allocated to a degenerated server to another server as a result of server degeneration is taken into consideration. In an embodiment, an information processing device which evaluates the performance of the computer system estimates the performance of the computer system when operation of a server included in the computer system is stopped based on the throughput required for the server at the time of operation stop and outputs the estimated performance of the computer system.

Performance evaluation method and information processing device

A management apparatus comprises a processor configured to execute a program and a storage resource configured to store the program, wherein the processor executes: an identifying process configured to identify an another job having a scheduled execution period overlapping with a scheduled execution period of an estimation subject job among a plurality of jobs executed at a first server from the plurality of jobs; a calculating process configured to calculate an islanding execution time in which the estimation subject job is executed individually at the first server based on the scheduled execution period of the estimation subject job and the scheduled execution period of the another job identified in the identifying process and a creation process configured to create a schedule which correlates the estimation subject job with the islanding execution time calculated in the calculating process.

Job scheduling apparatus and method based on island execution time

It is provided a computer system comprising a management computer to be coupled to a management subject resource managed by the management computer, which includes at least one of a server apparatus, a storage apparatus or a network apparatus, and a display computer coupled to the management computer. The management computer includes a memory storing at least one workflow program including a work procedure, and a CPU configured to execute the at least one workflow program. The work procedure changes a configuration of the management subject resource, and acquires information from the management subject resource. The CPU executes prior verification processing of verifying an operation environment of the management subject resource to operate the work procedure included in the at least one workflow program before execution of the at least one workflow program, and displays an execution result of the prior verification processing on the display computer.

Computer system and program for prior verification of a workflow program

A plurality of process content is retained, said process content including identifiers of a plurality of part content included in each process and information which denotes dependencies among the plurality of part content. When information is inputted which designates a first process and the part content of a problem portion which is included in the first process, a process similar to the first process is retrieved. On the basis of whether there is a change in any of the plurality of part content which is included in the retrieved process, an evaluation value of the retrieved process is either incremented or decremented, and the information relating to the plurality of processes is outputted on the basis of the evaluation value.

Management system, management program, and management method

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.

Operation delay monitoring method, operation management apparatus, and operation management program

A monitoring system for providing services to clients as an embodiment of the present invention is characterized in that upon determining whether or not termination times of the service-providing computers currently acquiring packets have been reached, service-providing computers that constitute a service-providing system other than the service-providing system constituted by the service-providing computers that have reached the termination times are selected as new packet acquisition destinations.

Service monitoring system, service monitoring method, and non-transitory computer-readable recording medium

An absolute path name and a command line of a process associated with a process operating on a business server are found from process information acquired from the business server. A standard process decision unit judges an OS standard process. An interpreter decision unit judges an interpreter name from the command line. A shared directory decision unit judges an executive file name located directly under a shared directory. A subdirectory decision unit judges a parent-child relation of an executive file directory from the absolute path name of the executable file. As a result, an application name recognition unit recognizes a name of an application.

Configuration management server, name recognition method and name recognition program

Using a service server list containing addresses of servers within a service system and an application list containing names of active applications within the service system, addresses of servers on which the active applications are running, and communication source addresses and communication destination addresses of the active applications, the following processes are carried out: specifying applications of a first layer in the service system from among applications lying within the service system; specifying applications of a second or subsequent layer in the service system from the application list and from addresses of servers on which the applications of the first layer are running; and judging applications having the same application name among applications belonging to the same layer as being of the same role for aggregation.

Information processing apparatus and method of operating the same

To construct an operation environment for a job by deploying in a computer an operating system and various programs as a premise of operation of a job program of the job of which operation is to be started in a job system, there is selected an optimized construction procedure requiring the shortest construction time. Various application programs and patch programs for the deployment included in the saved disk images are compared with the various programs as a premise of the job operation to obtain a period of time to uninstall unnecessary programs, a period of time to install lacking programs, and a period of time to deploy the disk image on the computer. An estimated construction time is obtained by adding the periods of time to each other. By optimizing the uninstallation and installation procedure, the estimated construction time is reduced to the maximum extent.

Method for constructing job operation environment

In a method of reducing a running cost and labor required for quality measurement, client computers matching predetermined district information are selected from a plurality of management target computers receiving network services, a quality measuring program is installed in these client computers to obtain execution results of the quality measuring program, and the quality of network services when the management target computers in the service target district access a server computer.
