ABSTRACT:
A job scheduling analysis method and system are disclosed in which a job schedule is analyzed by use of historical job execution data in a computer system in which a plurality of jobs are executed in parallel. Historical execution data of a plurality of jobs and the file names of files accessed by the jobs are collected. The maximum multiplicity of jobs capable of operating in parallel on the computer system is inputted. When the file name of a file accessed by one job and the file name of a file accessed by another other job coincide with each other, an execution start condition of the plurality of jobs are determined to execute the one job and the other job at the earliest instants within the maximum job multiplicity so that the sequence of execution of processings by the one job and the other job is maintained and the execution time of the one job and the execution time of said other job do not overlap each other. Thereby, it is possible to simulate the influence of a change in system construction and to search for an effective batch processing with a reduced number of idle spaces.
