Abstract: A method includes: first creating determination information on whether or not the second file is derived from the first file based on a file name or file content of a first file to which writing is performed by a first job and a file name or file content of a second file from which reading is performed by a second job; second creating predecessor-successor information indicating a predecessor-successor relationship between the first job and the second job based on the determination information; and outputting the predecessor-successor information in a manner that allows an administrator to keep track of the predecessor-successor relationship between the first job and the second job.

Abstract: A data specification method executed by a computer, the method including obtaining a plurality of data groups, specifying a number of types of a plurality of values included in each of the plurality of data groups, obtaining a result of a calculation process using a plurality of values included in a specified data group, specifying a number of types of the plurality of values included in the specified data group, selecting one or more data groups based on the number of types of the plurality of values included in the specified data group and based on the number of types of the plurality of values included in each of the plurality of data groups, and specifying a corresponding data group corresponding to the specified data group from among the selected one or more data groups.

Abstract: A control method executed by a control device, the control method including identifying a specified time period based on execution history information on previous jobs related to the plurality of systems, the specified time period being a period prior to execution start timing of a first job, update processing for a data storage area from which the first job refers to data is not executed during the specified time period, performing control so that evaluation timing of an amount of the data that the first job refers to from the data storage area is included in the identified time period, determining a specified system among from the plurality of systems based on the amount of the data evaluated at the evaluation timing, and causing the specified system to execute the first job.

Abstract: A job execution calendar management device includes a processor configured to acquire, from an information processing system, first pieces of calendar information respectively indicating timings for starting first jobs, access table information indicating which one of first tables has been accessed respectively by the first jobs, and type information indicating a type of respective data manipulations performed on the first tables through the accesses by the first jobs. The information processing system starts the first jobs on basis of the first pieces of calendar information. The processor is configured to identify transaction tables storing information added by any one of the first jobs, among the first tables on basis of the type information and group second pieces of calendar information among the first pieces of calendar information on basis of the access table information. The second pieces of calendar information correspond to second jobs accessing a same transaction table.
