  • Patent number: 9658883
    Abstract: A controller apparatus obtains job history information including execution records of one or more jobs not registered in a scheduler. Based on the job history information, the controller apparatus then estimates resource usage during execution time periods initially scheduled for jobs registered in the scheduler. This resource usage includes that of at least one of the jobs not registered in the scheduler which is to be executed together with the registered jobs on an information processing apparatus. When the estimated resource usage satisfies predetermined conditions, the controller apparatus schedules jobs including the registered jobs and the at least one of the non-registered jobs.

  • Publication number: 20170011357
    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.
