1. A heavily loaded resource evaluation system comprising:

  • a system management facility file, in which the status of utilization of each of a plurality of resources constituting a computer system is recorded at regular intervals as a system resource utilization record, and further an execution hysteresis of each job executed on said computer system is recorded at regular intervals as a job activity record;

    a system configuration file, in which information on connective relationship between one or more external memory units which are constituent elements of said computer system and an external memory control unit for controlling said one or more external memory units and names of files stored in said one or more external memory units are stored as system configuration data;

    a system management facility record input program for inputting each of said system resource utilization records and said job activity records in said system management facility file;

    a resource utilization ratio threshold value file, in which an alarm value and a limit value, within a performance guarantee, for a resource utilization ratio of each of the resources constituting said computer system are stored as threshold values of the resource utilization ratio;

    a heavily loaded resource selection program for comparing information on the resource utilization ratios in said system resource utilization records entered by said system management facility record input program with the limit value of the resource utilization ratio in said resource utilization ratio threshold value file, and extracting a resource name, a recorded time and the resource utilization ratio in a particular system resource utilization record indicating a heavily loaded status of utilization surpassing the limit value;

    a heavily loaded resource information record generation program for extracting, after actuating said system management facility record input program and said heavily loaded resource selection program, the recorded time of said particular system resource utilization record extracted by said heavily loaded resource selection program, a job name in the job activity record entered by said system management facility record input program, information on the resource utilization ratio of each resource, and information on other resource names and information on the resource utilization ratio in said particular system resource utilization record entered by said system management facility record input program, and for further referring to the system configuration data in said system configuration file, and generating a single heavily loaded resource information record by integrating information on each resource and information on jobs using the resource, or integrating information on each resource and information on resources constituting that resource, in a correlated manner; and

    a heavily loaded resource information file, in which said single heavily loaded resource information record generated by said heavily loaded resource information record generation program is stored.
