Description

  The present invention relates to a program interface in job input / output on a computer, allocation / release of a file used in a job and a file for outputting a job execution result, and job management for controlling execution of a user program executed in the job, and Concerning the user interface.

  A unit of work to be executed by a general-purpose computer is called a job. In order to execute a job on a general-purpose computer, first, a job definition is input to job management for managing the job and its execution result. A job definition is a file that describes the job name, execution method, used files, which are input resources required to execute the job, and execution results, which are output resources, in a language that can be understood by job management. is there.

  In job management, after checking the grammar of the job definition, a job identifier for uniquely identifying the job is assigned and the job is executed. In addition, the job analysis result is recorded so that the processing contents of the job can be confirmed.

  In job management, a job is executed in accordance with an instruction from the job scheduler. At this time, an area for storing the job execution result is allocated to the storage device.

  In a general-purpose computer, a job management function is executed by an OS (operating system), and an execution result from any program is uniquely managed by associating the job name or job identifier with the job result, and inquiring the OS. I was able to do it. In job management on a computer that does not have job management as an OS function, a job management program other than the OS uses job result management information to associate a job name or job identifier with an execution result, and A technique for managing files so as to always have a unique execution result is disclosed.

  By managing job execution results with this technology, if in the computer, the user can specify the job identifier or job name, and inquire the OS from the job result display program, job result deletion program, or print program. The job execution result can be displayed, deleted, and printed.

  Patent Document 1 discloses a technique for managing a history by giving an attribute to a job execution result.

JP 2007-28019 A

  The above prior art is a technique that operates in a state in which execution results are always managed, and where the execution results exist on the storage device must always be managed in the management device or the OS. In particular, when the job result file is a plurality of files, each job result is moved separately, or an error occurs in the device that manages the job results. There was a problem that it was impossible to manage the result. It is an object of the present invention to make it possible to confirm from the execution result which job the execution result of the job is, even when a transfer of the execution result or an abnormality of the management apparatus occurs.

  In order to achieve the above object, a job management program according to the present invention includes a step for controlling an input / output file and a user program according to a job definition, and a file for assigning a file to be input / output by the job before the user program is executed. In the assignment process, the execution result file output by the user program is assigned in advance, and the property is affected by the step of assigning the property to the assigned file and the user program executed for the execution result file with the property to which the property is assigned. The interface that uses the file that can output the result without the output, and the step that handles the execution result file with properties in the same way as the execution result file without properties after the execution result is output by the user program and the execution is completed. It is characterized by having a flop, steps that may refer to a property of the execution result file.

  In the above processing, it is possible to create an execution result file that has job information according to the job definition as a property without changing the user program, so there is no need to modify or recompile the user program. You can get information about the job by looking at the properties of the execution result.

  As a specific example, in the past, it was impossible to determine which job was the execution result created without obtaining information from a management device such as job result management information. Even if the execution result file is transferred over the network to an unobtainable server, it is possible to determine which job has been created based on the job attributes in its properties, and that the job has been executed. Validity can be judged.

  Also, in the job management program, by assigning a unique job identifier for the job in the step of assigning the property, when the same execution result that was created when the same job was executed many times is executed It is possible to determine whether the execution result is completed. Similarly, by assigning a job name, it can be determined that a job executed with the same job definition is an output execution result, and by setting a status such as whether the execution result is normal end or abnormal end, normal It is also possible to determine that only the execution result at the time is used. In particular, when a plurality of execution results are determined collectively, the management can be performed in a lump by rearranging them in the order of information assigned to each property.

  Also, in the present invention, when the same information as the content to be assigned to the property is managed as job result management information by the management apparatus as in the conventional case, the job management program creates the job result management information based on the property content. As a means, a job result management information recovery program may be prepared, in order to achieve the purpose of correctly reconstructing job result management information when there is a contradiction in job result management information. is there.

  According to the present invention, by setting job attributes as properties in a file that outputs job execution results, it is possible to collectively manage the execution results of a plurality of jobs as compared to the prior art.

  The present invention further provides the user with a user interface that collectively manages job execution results based on job identifiers and job names by setting job identifiers and job names in properties of job result files with properties. .

  The present invention further provides an effect of preparing a program for reconstructing job result management information from the properties of a job result file with properties so that it can be recovered if there is a failure in the job result management information.

  The present invention further provides an effect of providing a user with a GUI interface for managing job execution results by displaying the properties of a job result file with properties on a GUI (Graphical User Interface) file property screen or filer screen. is there.
