Abstract

PURPOSE:To prevent the concentration of a file access and to enhance the efficiency of multiprogramming by providing a spool file recognizing means, a spool file identifier determining means, a job identifier allocating means, etc. CONSTITUTION:In the case of the start of a system 100, a file which can be used as a spool file is recognized, and a spool file identifier determining means 2 allocates the spool file identifier of a format by which the utilization purpose of its file is known. When a job is inputted from an input device 12, a unique job identifier is allocated by a job identifier allocating means 3. A spool file identifier allocating means 4 selects the spool file identifiers of each utilization purpose one by one, forms each of them as a group and stores them in a spool file identifier storage part 11. When the job is executed, the result of execution is stored in the spool file with a job execution result store means 7.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a spool file management method in a system that performs job spooling, and particularly relates to a spool file management method in which spool files are distributed and managed over multiple volumes. File distribution method [Conventional technology] In order to improve the sharability of input/output devices, job streams consisting of a job control language and user data and job execution results are stored in a spool file, which is a sharable intermediate medium. A job processing form called spooling has been used in the past, but in the past, only one spool file was prepared for each purpose, such as storing job streams and storing job execution results.

[Problem to be solved by the invention] As mentioned above, in the past, only l files were prepared for each purpose of use, which caused the problem that file access was concentrated and the effectiveness of multiple programming was reduced. Ta.

An object of the present invention is to improve the effectiveness of multiple programming by preventing concentration of file accesses.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a spool file recognition means for searching a plurality of volumes at the time of system startup and recognizing files that can be used as spool files in a system that spools jobs; a spool file identifier determining means for assigning a spool file identifier according to the purpose of use to a file recognized as usable by the file recognition means; a job identifier assigning means for assigning a job identifier to a submitted job; spool file identifier assignment means for determining a spool file identifier of a spool file for each usage purpose to be assigned to the submitted job based on the assigned job identifier; job stream storage means for storing the job stream in a spool file whose usage purpose among the spool file identifiers for each usage purpose determined by the means corresponds to a spool file identifier for job stream storage; job stream reading means for reading a job stream from a spool file corresponding to the job stream identifier for storing the job stream determined by the spool file identifier allocation means; and job stream reading means for reading the execution result of the submitted job by the spool file identifier allocation means. storage means for storing in a spool file whose usage purpose among the determined spool file identifiers for each usage purpose corresponds to a spool file identifier for storing job execution results; and when outputting the execution results of the submitted job; The job execution result reading means reads the job execution result from the spool file corresponding to the spool file identifier for storing the job execution result determined by the spool file identifier allocation means and outputs it to the output device.

[For production]

Spool file! ! ! The it+ means searches multiple volumes at system startup and recognizes files that can be used as spool files. The spool file identifier determining means assigns a spool file identifier suitable for the purpose of use to the file recognized by the spool file recognition means. The job identifier assignment means assigns a job identifier to the submitted job. The spool file identifier assigning means determines the spool file identifier of the spool file for each usage purpose to be assigned to the submitted job based on the job identifier assigned by the job identifier assigning means. The job stream storage means stores the job stream of the submitted job in a spool file corresponding to the spool file identifier for job stream storage determined by the spool file identifier allocation means. When a job is executed, the job stream reading means reads the job stream from the spool file corresponding to the spool file identifier for job stream storage determined by the spool file identifier allocating means, and the storing means stores the job execution result in the spool file identifier allocating means. The job execution results are stored in the spool file corresponding to the spool file identifier for storing the job execution results determined by . When the job execution result is output, the job execution result reading means reads the job execution result from the spool file corresponding to the spool file identifier for storing the job execution result determined by the spool file identifier allocation means and outputs it to the output device.

(Example) Next, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, and a system 100 according to the embodiment includes a spool file 112 means 1, a spool file identifier determining means 2, a job identifier assigning means 3, and a spool file identifier assigning means. 4
, job stream storage means 5, job stream reading means 6, job execution result storage means 7, job execution result reading means 8, volumes 9-1 to 9-4, and spool files lO-1 to 1o. -8, a spool file identifier storage unit 11, and an input device 1 such as a card league.
2, and an output device 13 such as a line printer.

Next, the operation of this embodiment will be explained using FIG.

When the system 100 is started up, the spool file recognition means 1 searches the volumes 9-1 to 94 and recognizes files that can be used as spool files. The spool file identifier determining means 2 applies a spool file that is recognized as usable as a spool file by the spool file recognition means 1 to a spool file in a format in which the purpose of use (for storing a job stream, for storing job execution results, etc.) is known. Assign a file identifier. At this time, spool file identifiers are assigned so that the number of spool files for each purpose of use is equal and that spool files for the same purpose of use are not provided in the same volume.

Thereafter, when a job is input through an input device 12 such as a card reader, the job identifier assigning means 3 assigns a unique job identifier to the job in the system 100. For example, when the job identifier assigned by the job identifier assignment means 3 is a numerical value, the spool file identifier assignment means 4 selects a spool file corresponding to the remainder when the number of spool files is divided by the above numerical value. Based on the job identifier assigned by the identifier assignment means 4, one spool file identifier for each usage purpose is selected from among the spool file identifiers defined by the spool file identifier determination means 2, and the spool file identifier for each usage purpose is selected. The spool file identifier and the job identifier assigned by the job identifier assigning means 3 are combined and stored in the spool file identifier storage section 11. Therefore, this spool file identifier storage unit 11
By referring to , you can find out which volume and file the spool file corresponding to the job identifier is. Note that data within the same spool file is managed using job identifiers. Further, a job stream composed of the job control language and user data of the job inputted from the input device 12 is stored in the spool file identifier storage unit 11 by the job stream storage means 5, and is paired with the job identifier of the job. The usage purpose among the spool file identifiers for each usage purpose stored in the spool file is stored in the spool file corresponding to the spool file identifier for job stream storage.

When executing a job, the purpose of use among the spool file identifiers for each purpose stored in the spool file identifier storage unit 11 in pairs with the job identifier of the job is the spool file identifier for job stream storage. The job stream corresponding to the above-mentioned job is read from the corresponding spool file by the job stream reading means 6, and the execution result of the job is stored in the ship among the spool file identifiers for each usage purpose stored in the spool file identifier storage unit 11. The job execution result storage unit 7 stores the job execution result in a spool file corresponding to the spool file identifier for storing the execution result.

In addition, when outputting the job execution results, the job execution result reading means 8 selects one of the spool file identifiers for each usage purpose stored in the spool file identifier storage unit 11 in pairs with the job identifier of the above-mentioned ship. The execution result of the job is read from the spool file corresponding to the spool file identifier for storing the job execution result and output to the output device 13 such as a line printer.

〔Effect of the invention〕

As explained above, the present invention creates spool files distributed over multiple volumes in a system that performs spooling.
This has the effect of preventing concentration of file accesses and increasing the effect of multiple programming, and also has the effect of being able to follow an increase in the number of jobs to be executed. Further, according to the present invention, even if a failure occurs in a volume containing a spool file, the spool file can be replaced with a spool file in another volume, which has the effect of preventing a system down.
