FIG. 9 is a diagram for explaining the transition of the used license list in the license delay.

  First, the operation of the job queue management unit 31 will be described with reference to FIG. Here, job and license management is performed.

  The job queue management unit 31 sets a variable n = 0 indicating the position from the head of the job queue 33 (step A1).

  One job is extracted from the nth job queue 33 in which the user's job is stored (step A2).

  A license necessary for executing the extracted job is defined as a license α.

  The license management unit 32 is inquired as to whether one or more licenses α are available. When the license management unit 32 returns an answer indicating that there is no free space for the license α (the license α cannot be used) (“No” in Step A3), the job queue management unit 31 returns the job to the nth job queue 33 (Step S3). A4). Then, the process proceeds to Step A7.

  When the license management unit 32 returns an answer indicating that the license α is available (“Yes” in Step A3), the license management unit 32 decrements the number of available licenses α recorded in the license management table 34 by 1 (Step S3). A5). Then, the process proceeds to Step A6.

  The job queue management unit 31 distributes the extracted job to the job execution device 4, notifies the job execution device 4 of the job name and job number, and requests execution of the job. The job execution device 4 executes the job (step A6).

  The job queue management unit 31 increments n by 1 (step A7) and repeats the above processing to the end of the job queue 33 (step A8).

  When the job execution device 4 finishes executing the job, it notifies the job queue management unit 31 of the job execution end (step A9). At this time, the job execution device 4 also notifies the job number of the completed job.

  The job queue management unit 31 notifies the license management unit 32 that one license α is available together with the job number. The license management unit 32 increments the number of vacant licenses α recorded in the license management table 34 and deletes the entry corresponding to the job number of the completed job on the use license list 35 (step A10).

  Next, the operation of the license management unit 32 will be described with reference to FIGS. In the license management unit 32, the license delay function prevents the license from being monopolized by one user. The license delay time h is a time for ensuring that the same license is not used by the same user for a certain period of time after being used by a certain user.

  The job queue management unit 31 specifies a license name (license α in this example), a user ID, and a job number, and inquires the license management unit 32 about the availability of the license α.

  The license management unit 32 first initializes a variable n (step B1).

  With reference to the license management table 34, it is checked whether or not the number of used licenses x exceeds the total number of licenses X (step B2). When the number of used licenses x is equal to or exceeds the total number of licenses X (“no” in step B2), the user cannot use the license α (step B8). The license management unit 32 replies to the job queue management unit 31 that the license α cannot be used.

  If the number of used licenses x is smaller than the total number of licenses X (“Yes” in step B2), the used license list 35 is checked from the top, and there is a license α with the same user whose use start time is within the license delay time h. Is checked (step B3 to step B7).

  If there is a license α for the same user whose use start time is within the license delay time h (“Yes” in step B6), the user cannot use the license α at that time (step B8). The license management unit 32 replies to the job queue management unit 31 that the license α cannot be used.

  If there is no license α for the same user whose use start time is within the license delay time h (“Yes” in step B3), the use license list 35 includes the license name, user ID, license use start time (current time), and The job number is recorded (step B9).

  Then, the number x of used licenses in the license management table is incremented by 1 (step B10). Decrease the number of unused licenses by one.

  The license management unit 32 returns an answer indicating that the license α is empty to the job queue management unit 31 (step B11). The user can use the license α (the user's job can be executed).

  Furthermore, the operation of the license management unit 32 will be described more specifically with reference to FIG.

  The use license list 35 is as shown in FIG. The license delay time is 30 seconds.

  At 10:45:10, the user ID = u requests the use of the license α. Since user ID = u is within the license delay time (30 seconds have not elapsed since 10:45:00), the license α cannot be used.

  At 10:45:20, user ID = y requests the use of license α. User ID = y can use the license α. The license name, user ID, license use start time, and job number are registered in the use license list 35. The use license list 35 is updated as shown in FIG.

  At 10:45:35, user ID = u requests use of the license α. User ID = u can use the license α (because 30 seconds have passed since 10:45:00). The license name, user ID, license use start time, and job number are registered in the use license list 35. The use license list 35 is updated as shown in FIG.

  Next, the license release process of the license management unit 32 will be described.

  The job queue management unit 31 notifies the license management unit 32 that one license α is available together with the job number.

  The license management unit 32 updates the number x of licenses used in the license management table 34 by -1. Add 1 to the number of unused licenses. The entry corresponding to the job number of the completed job on the use license list 35 is deleted.

  As described above, by providing means for not assigning the same license to the same user within the license delay time h, there is an effect of preventing the license from being monopolized by one user.

  Next, a second embodiment will be described. In the second embodiment, licenses that are not being used are dynamically distributed.

First, the configuration of the second embodiment will be described in detail with reference to the drawings.
FIG. 10 is a diagram showing the configuration of the second embodiment of the present invention.
FIG. 11 is a diagram showing an example of the project license management table.
FIG. 16 is a diagram illustrating an example of a job queue.

  Referring to FIG. 10, the second embodiment of the present invention includes a user terminal 5, a job reception device 6, a queue system device 7, and a job execution device 4. Although one user terminal is illustrated in FIG. 10, a plurality of user terminals may be provided.

  The user terminal 5 is equivalent to the user terminal 1 of the first embodiment described above. In the means for sending the job name to the job receiving device 6, when the job name is sent, the project name is also sent in addition to the license name necessary for executing the job. The project name may be entered by the user. Alternatively, the user terminal 5 may be provided with a job name / project name correspondence table, and the project name may be acquired from the input job name.

  The job reception device 6 is equivalent to the job reception device 2 of the first embodiment described above. Note that the means for receiving the job name sent from the user terminal 5 accepts the project name in addition to the license name. Further, in the means for requesting registration to the job queue 33 by transmitting the accepted job name to the queue system device 7, the project name is also transmitted in addition to the license name.

  The queue system device 7 is an information processing device that operates under program control, and includes a job queue management unit 71, a license management unit 72, a job queue 73, and a project license management table 74.

  The job queue management unit 71 is equivalent to the job queue management unit 31 of the first embodiment described above. An example of the job queue 73 is shown in FIG. When inquiring to the license management section 72 whether or not there is a vacant license necessary for executing the extracted job, the inquiry is also made with the project name added.

The license management unit 72 includes the following means.
(72-1) Means for checking whether or not there is a vacant license inquired from the job queue management unit 71 with reference to the project license management table 74 and returning the check result to the job queue management unit 71. An example of the project license management table 74 is shown in FIG. The license table in the project license management table 74 includes a section indicating the originally allocated project (sometimes referred to as an original project name) , a last use time, an in-use flag, and a rented job number. The area of the project license management table 74 is secured in an auxiliary storage device (not shown) such as a magnetic disk.
(72-2) License acquisition processing means. In other words, in the project license management table 74, a license flag whose usage flag is “unused” is selected, and the busy flag of the selected license table is set to “in use”. Details of the operation of the license acquisition processing means are shown in FIG.
(72-3) License rearrangement means. That is, the license relocation is performed so that the license is preferentially turned to the project with the highest license usage rate at that time. Details of the operation of the license relocation means are shown in FIG.
(72-4) License release means. That is, when the job ends and one free space is generated in the license, it is reflected in the project license management table 74. Details of the operation of the license releasing means are shown in FIG.

Next, the operation of the second embodiment will be described in detail with reference to the drawings.
FIG. 12 is a diagram for explaining the license automove.
FIG. 13 is a diagram showing the flow of the operation of the license relocation process in the license management unit.
FIG. 14 is a diagram showing a flow of operation of license acquisition processing in the license management unit.
FIG. 15 is a diagram showing the flow of operation of the license release process in the license management unit.

  Next, the operation of the license management unit 72 will be described with reference to FIGS.

  When a certain number of licenses are allocated to each project, there are as many license tables as the number of licenses allocated to the project as shown in FIG. Each license table includes a term indicating the originally allocated project, a term indicating the last time the license was used, a flag indicating whether the license is in use, and a rented job number.

  First, license rearrangement (license automove) will be described with reference to FIG.

  First, project from all license tables in the project license management table 74! = Original project (ie license table temporarily redistributed from another project), use flag is off (ie unused), and difference between last use time and current time is k (when license is not used) Those exceeding the waiting time for rearrangement are put into a table buffer (not shown in FIG. 10) (step C1). The table buffer is a buffer for temporarily recording the license table.

  When the table buffer is full or all license tables have been searched, the last use time of the license table in the table buffer is updated to the current time (step C2).

  Each license table in the table buffer is added to the original project (step C3). By the operation so far, the license that has been redistributed but remains unused for a long time is returned to the original project.

  Next, in order to redistribute the actual license, first, the license usage rate of each project is calculated. The license usage rate is calculated by the following formula. “License usage rate = number of license tables with a license in use flag / total number of license tables”. Then, the projects are sorted in ascending order of license usage rate (step C4).

  The license table is examined in order from the project with the lowest license usage rate (step C5).

  Check the last use time of the license table, and if there is a license table where the difference between the last use time of the license and the current time exceeds k (waiting time for relocation when the license is not used), temporarily save it in the table buffer (step C6).

  When the table buffer is full or the license search for all projects is completed, the process proceeds to the next process (step C7).

  The last use time of the license table in the table buffer is updated to the current time, and the license table saved in the table buffer is added to the project with the highest license usage rate (step C8).

  Wait for a certain time (for example, 1 to 2 seconds) (step C9), and return to step C1.

  By performing this operation, the license can be given priority to the project with the highest license usage rate at that time. Further, by adjusting the size of the table buffer, it is possible to limit the number of licenses that are redistributed at a time, thereby preventing the licenses from being concentrated on only one project.

  Next, the license acquisition process will be described with reference to FIG.

  When acquiring a license, first, from the license table of the corresponding project, a project = original project (a license table originally assigned to the own project) and an unused one are searched (step D1).

  If there is such information (“Yes” in step D2), the in-use flag is raised (step D6), and the license acquisition is completed (step D7).

  If there is no corresponding item (“No” in step D2), the project in the license table of the corresponding project! = Search for an original project (a license table that is originally allocated to another project and is temporarily redistributed from another project) and that is unused (step D3).

  If there is no corresponding item (“No” in step D4), the license cannot be acquired (step D8).

  If there is a corresponding one (“Yes” in step D4), the one with the latest use time is selected from the corresponding licenses (step D5), the in-use flag is raised (step D6), and the license acquisition is completed. (Step D7).

  By this operation, it is possible to preferentially use the license assigned to the own project as much as possible, and to easily return the license redistributed from another project to the original project.

  Next, a license release process will be described with reference to FIG.

  The job ends and one free space is generated in the license (step E1).

The license table of the project license management table 74 is searched with the job number of the completed job, and the originally assigned project name is extracted from the original project name in the license table (step E2).
On the job queue 73, it is confirmed whether there is a job waiting for the license with the extracted project name (step E3).

  If there is a corresponding job (“Yes” in step E4), the license table corresponding to the released license is moved to the project indicated by the original project name (step E5). Then, the process proceeds to Step E7.

  If there is no corresponding job (“No” in step E4), the license table is not moved and the license table is left in the current project (step E6).

  Thereafter, the busy flag is lowered, and the last update time in the corresponding license table is updated to the current time (step E7).

  The release of the license is terminated (step E8).

  This operation returns the relocated license to the original project as quickly as possible when the original project requires it.

  As described above, the license relocation means for dynamically allocating licenses that are not used is provided, so that the use efficiency of the license is improved.
