Abstract

PURPOSE:To reduce the load of an operator by comparing the total capacity of blank areas in a system output file with a prescribed threshold in a prescribed period, and when the total capacity is reduced less than the threshold, automatically opening the area used by the most precedently outputted job out of outputted jobs. CONSTITUTION:Plural job results obtained by multiplex processing in the system are stored in a system output file 1, and at the end of output, a job result output/storage control part 6 transfers the corresponding job result information from a job result control table 5 to an outputted job result control table 4. The control part 6 calculates the total capacity of blank areas in the file 1 from a file control table 3, compares the calculated value with the prescribed threshold, and when the calculated value is less than the prescribed value, decides whether the outputted job results have been registered in the table 4 or not. When the outputted job results have been registered, the control part 6 releases the most precedently outputted job result from the table 3.

Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention Industrial Field of Application The present invention relates to an information processing method in which the execution results of multi-processed jobs are saved in a system output file in preparation for re-output even after the output is finished. Concerning a job execution result management method applied to the system.

2. Description of the Related Art In general, in an information processing system, execution results of multiple jobs are stored in an external storage device called a system output file, and are output after being queued in an output queue.

Some information processing systems adopt a management method in which job execution results are saved in the system output file without being deleted immediately after the output is finished, so that the job execution results can be re-output even after the output is finished. There is.

In such a job execution result management method, a predetermined number of outputted job execution results are usually saved in order from the most recent to the most recent. In other words, each time the total number of job execution results that have been output reaches a predetermined number, the area in the file that was used to store the first (oldest) job execution result is freed and used for storing other job execution results. assigned to.

However, it is not used to save job execution results.
Since the size of the storage area differs depending on the job, if only the total number of output job execution results is managed, the storage area will be exhausted and there is a risk that the job being executed will be abnormally terminated.

Therefore, a threshold value is set in advance for the total amount of free storage space, and when the total amount of free space is less than this threshold, a message is displayed on the console, and the output job execution results are displayed with operator intervention. A method of deleting the data or saving it to another external storage device such as a magnetic tape is also used.

Problems to be Solved by the Invention In the conventional job execution result management method described above, the operator must perform operations such as deleting or saving the output job execution results in response to notifications to the console, which places an excessive burden on the operator. Become.

Furthermore, if free space runs out due to a delay in operator response, more important jobs that are currently being executed may be abnormally terminated in order to save the job execution results that have already finished output and are no longer important. There is also the unreasonableness of being forced to do so.

Configuration of the Invention Means for Solving the Problems The job execution result management method of the present invention which solves the problems of the prior art described above compares the total amount of free space in the system output file with a predetermined threshold value at a predetermined period. When the total amount of free space falls below a threshold, the used space of the first output job is automatically released, reducing the burden on the operator and eliminating the need for operator intervention. The system is configured to reliably prevent a job in progress from being abnormally terminated due to a lack of free space due to a delay.

Hereinafter, the operation of the present invention will be explained in detail together with examples.

Embodiment FIG. 1 shows job execution results (hereinafter referred to as "
1 is a functional block diagram illustrating a configuration of a portion related to this embodiment of an information processing system to which a management method for managing job results (abbreviated as "job results") is applied.

l is the system output file, 2 is the file allocation part, 3
is a file management table; 4 is an output job result management table that manages information on output job results; 5 is an output waiting job result management table that manages information on job results waiting to be output in the form of a queue; 6 is a job A job result output/save management section 7 manages output and storage of results, and 7 is an output control section that controls output of job results from the system output file 1.

The system output file 1 is comprised of an external storage device that stores the results of multiple jobs that are multiplexed within this information processing system.

The file allocation unit 2 receives a request to allocate a job result storage area in the system output file 1 from a higher-level resource management unit (not shown), searches for an empty area in the file management table 3, and allocates this empty area to the job related to the allocation request. Allocated for storing results. The file allocation unit 2 notifies the resource management unit of the allocated storage area, and also writes a "job name" and an "in use" identifier into the allocated area.

Every time the output control unit 7 receives a notification that output is possible from the upper level part, it searches for the next job result to be output from the queue in the output waiting job result management table 5, and outputs the job result from the system output file 1. Read and transfer to the specified output device.

When the output of the job results is finished, the output control unit 7 sends the fact and the corresponding job name to the job result output/save management unit 6.
to notify.

When the job result output/storage management unit 6 receives the job result output completion notification from the output control unit 7 , it moves the corresponding job result information from the output waiting job result management table 5 to the output job result management table 4 . Further, each time the job result output/storage management unit 6 receives a job result output request from a higher-level part, it adds information regarding the job result to the queue in the output waiting job result management table 5.

The output job result management table 4, as illustrated in FIG. 2(A), is constituted by a chain list of job names in which job names of output job results are linked by pointers in the order of output completion.

The output waiting job result management table 5, as illustrated in FIG. 2(B), is composed of a chain list of job names linked by pointers in the order in which the job names of the output waiting job results are queued for output. .

When the job result output/storage management section 6 receives a command to start the release process issued from the timer 8 at a predetermined period, it starts the release process as illustrated in the flowchart of FIG.

The job result output/save management unit 6 performs the first step 11.
In this step, the total capacity of free space in the system output file 1 is calculated from the file management table 3. 4 In the next step 12, the job result output/management unit 6 determines whether the total amount of free space in the system output file 1 is equal to or larger than a predetermined threshold. If the total amount of free space is equal to or greater than a predetermined threshold, the process ends without performing any release process.

On the other hand, if the total capacity of the free space is less than the predetermined threshold, it is determined in step 13 whether or not the output job result is registered in the output job result management table 4. If it is registered, in step 14, the job result that is registered in the output job result management table 4 and becomes output first (the oldest output job result) is searched. .

The job result output/save management unit 6 proceeds to the next step 15, searches for the storage area in the system output file l used to save the oldest job result from the file management table 3, and releases it. , the information regarding the job result is outputted in the output job result management table 4.
, and complete the release process.

In step 13, if there are no output job results registered in the output job result management table 4, the job result output/save management unit 6 determines that some situation requiring confirmation has occurred. , outputs a warning message to the console and terminates processing.

Effects of the Invention As explained in detail above, the job result management method of the present invention periodically checks whether the total free space of system output files is equal to or larger than a predetermined threshold, and sets this threshold to If the area is divided, the area used by the oldest job result is automatically released, which reduces the burden on the operator and eliminates the possibility that a running job may end abnormally due to a delay in the operator's response. This has the effect of reliably preventing this.
