Abstract

PROBLEM TO BE SOLVED: To make automatic job operation efficient by making it possible to confirm the priority of a quitting process in case of a power failure and operation state information at quitting time as to each job. SOLUTION: A job information registering means 101 registers the end priority, name, and reexecution necessity information of each job in a job information table 400 during system operation. If a power failure occurs, a job end priority retrieving means 102 detects respective execution jobs in the decreasing order of priority and a job operation state reference registering means 103 registers operation state information at quitting time of an execution job having 'information indicating that reexecution is necessary' set in the reexecution necessity information in a job operation state file 500. When the system is restarted, a reexecution job executing means 105 obtains the operation state information of the reexecution job detected by the reexecution job retrieving means 104 and starts the following processing of the reexecution job from the quitting point at the power failure time.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a UPS (Unin
terruptable Power System:
In a computer system equipped with an uninterruptible power supply (hereinafter sometimes simply referred to as “system”), a job being executed is automatically terminated in the middle of a system termination process when a power failure occurs during its operation U to restart the operation of the job after the power failure
The present invention relates to an automatic job operation method using PS cooperation.

[0002]

2. Description of the Related Art Conventionally, in this type of automatic job operation system based on UPS coordination, a function for performing a process of terminating (stopping) a job being executed during power supply from a UPS during a power failure or a system restart is performed. There was a function to do the processing.

[0003] However, in the conventional automatic job operation system based on the UPS cooperation, there is no way to know the importance of each job in the user's work in the process of terminating the running job performed when a power failure occurs.

Further, in the conventional automatic job operation system based on UPS cooperation, in order to recognize the progress of processing when a job that has been interrupted in the middle of a power failure has occurred,
After restarting the system, the user must look at the message log and determine the creation status of the file used for the job, etc. (Even if such determination is made, the recognition is limited. was there).

[0005]

The above-mentioned conventional UPS
The automatic job operation method by cooperation has the following problems.

The first problem is that when executing a system shutdown process in the event of a power failure, a set of jobs being executed is determined by the system (such as an algorithm for ending jobs in the order of startup or an LRU (Least Recentre).
y Used) algorithm, etc.), each job is terminated in a substantially random order,
This means that job operation efficiency of the entire system is not considered. For example, if a job for performing a write process on a file (such as a user file) is aborted early, there is a disadvantage that the integrity of data to be written is reduced, and the operation efficiency of the entire system is reduced.

The reason that such a problem occurs is that there is no way to know which job has a high importance in the user's work in the process of terminating the job being executed when a power failure occurs.

[0008] The second problem is that the user cannot recognize how much processing has been performed at the time of the termination of the job that has been terminated in the above-mentioned system shutdown processing, and the execution is terminated in the middle of the power failure. This means that it becomes difficult to re-execute the job from the time of the discontinuation when the system is restarted.

The reason why such a problem arises is that, in the prior art, in order to see the progress of processing at the time of aborting a job that has been aborted halfway, the file used at the time of the abort after restarting the system is used. This is because the user has to make a judgment by looking at the message log from the message log, and it is not possible to determine how much processing has been internally performed only from the external information (message log).

In view of the above, it is an object of the present invention to automatically determine the importance of each of the running job groups at the time of the occurrence of a power failure (the opposite of the importance is the priority of the execution of the abort process). Automatic job operation with UPS coordination that can recognize and can accurately recognize the progress (elapsed status) of the processing of a job that has been discontinued in the middle, and that enables more efficient automatic job operation with UPS coordination It is to provide a method.

[0011]

According to the automatic job operation system of the present invention, the priority of each job, the job name, and the necessity of re-execution are registered in a job information table during system operation. A job ending unit that searches for the job information table and detects each execution job from the execution job group in a descending order of priority during the system shutdown process according to an instruction from the UPS when a power failure occurs. A priority search unit, and an execution job detected by the job end priority search unit when a power failure occurs, and "re-execution necessity information" in the re-execution necessity information in the job information table. The job that performs the termination processing of each execution job after registering the operation status information at the time of termination of the job for which is set in the job operation status file Operation status reference registering means, re-execution job searching means for sequentially detecting all re-execution jobs by referring to re-execution necessity information for each job in the job information table at the time of system restart, and Re-execution job execution for acquiring operation status information for the re-execution job detected by the re-execution job search unit from the job operation status file and starting subsequent processing of the re-execution job from the time of termination when a power failure occurs Means.

In the automatic job operation system according to the present invention, job priority information, job name, re-execution necessity information, and wait time for each job are registered in a job information table during system operation. A job termination priority unit for searching the job information table and detecting each execution job from the execution job group in descending order of priority during the system shutdown process in response to an instruction from the UPS when a power failure occurs And a job retrieving necessity information in the job information table, wherein "information indicating that re-execution is necessary" is included in the execution job detected by the job end priority retrieving unit when a power failure occurs. After registering the operation status information at the time of termination of the set job in the job operation status file, perform the termination process of each execution job Job operation status reference registering means, and when a power failure occurs, for each execution job detected by the job end priority search means, the job operation status by a waiting time based on a wait time for the execution job acquired from the job information table. A waiting time processing unit that waits for abort processing by the reference registration unit; and a re-execution job that sequentially detects all re-execution jobs by referring to re-execution necessity information for each job in the job information table when the system is restarted. A search unit that obtains, from the job operation status file, operation status information for the rerun job detected by the rerun job search unit when the system is restarted, It is also possible to adopt a configuration having a re-execution job executing means for starting the processing.

[0013]

Next, the present invention will be described in detail with reference to the drawings.

UPS 200, terminal 300, job information table 400
And a job operation status file 500.

The computer 100 includes a job information registration unit 101, a job end priority search unit 102, a job operation status reference registration unit 103, a re-execution job search unit 104, and a re-execution job execution unit 105. It is configured.

Each of these means operates roughly as follows.

The job information registering means 101 provides, for each job, an end priority (information indicating a priority order for terminating (stopping) the job halfway when a power failure occurs), a job name (identification information of the job), and re-execution. A job information table 400 having necessity information (information specifying whether the job should be re-executed from the state at the time of previous execution when the system is restarted) is created (see FIG. 5). The re-execution necessity information is information indicating that re-execution is necessary (hereinafter, FIG. 5).
, And information indicating that re-execution is unnecessary (hereinafter, represented by “x” as shown in FIG. 5).

The job end priority search means 102 searches the job information table 400 at the time of system shutdown processing when a power failure occurs, and selects the end priority job among the jobs operating at that time (executing jobs). Find the job with the highest degree.

The job operation status reference registration unit 103 performs a system shutdown process when a power failure occurs.
At the time of system restart, the job information table 4
00 for the execution job for which the re-execution necessity information is set to “〇” (for example, the execution status immediately before aborting the process, the file access status, etc., from the time of the abort at the time of system restart). (Information necessary for restart) is registered in the job operation status file 500.

The re-execution job search means 104 searches the job information table 400 for a job to be re-executed (re-execution job) when the system is restarted.

The re-executing job executing means 105 stores the state of the re-executing job detected by the re-executing job searching means 104 at the time of the previous operation (processing progress at the time of termination at the time of the occurrence of power failure) in the job operation status file 500. And restarts the processing of the re-executed job from the time of termination based on the state of the previous operation.

FIG. 5 is a diagram showing a specific example of the contents of a job registration table 400 in the automatic job operation system based on the UPS cooperation according to the present embodiment. As mentioned earlier,
The job registration table 400 has an end priority, a job name, and re-execution necessity information for each job.
The end priority values are set to 1, 2, 3,... In descending order of priority.

FIG. 6 is a diagram for explaining a specific operation of the automatic job operation system using the UPS cooperation according to the present embodiment.

Next, with reference to FIG. 2, FIG. 3, FIG. 4, and FIG.
The overall operation of the automatic job operation method based on PS linkage will be described in detail.

First, an operation during system operation (before power failure occurs) will be described with reference to FIG.

The job information registration means 101 is a terminal
, Instructions and information are input (step 201), and a job information table 400 is created based on the instructions and information (step 202). That is, the job name, end priority, and re-execution necessity information are registered in the job information table 400 for each job group that can be executed in the computer system (see FIG. 5).

Second, the operation when a power failure occurs (when a power failure occurs during system operation) will be described with reference to FIG.

When a system shutdown instruction (an instruction for requesting a system shutdown process) is issued from the UPS 200 due to the occurrence of a power failure, the computer 100
While the power is being supplied from the UPS 200, the CPU 200 performs an abort process for the job group being executed, and executes a system shutdown process.

At the time of such a system shutdown process, the job end priority search means 102 selects the job having the highest priority (ie, the end priority) to be ended among the jobs currently being executed (executed jobs). Search for. That is, it is determined whether there is an execution job (step 3).
01), if it is determined in step 301 that there is an "executed job", the job information table 400 is searched to detect an executed job having the highest end priority (step 302).

Next, the job operation status reference registration means 103
Is the job end priority search means 102 in step 302
Information 4 for the execution job detected by
00, it is determined whether or not the execution job is a “job to be re-executed when the system is restarted” (by indicating whether the re-execution necessity information is “〇” or “×”). Is determined (step 303).

If the job operation status reference registration unit 103 determines in step 303 that the execution job is a job to be re-executed, the current operation of the execution job (that is, immediately before the termination due to a power failure) is performed. Operation status information indicating the status, the file access status, and the like is registered in the job operation status file 500 (step 304).

If the job operation status reference registration unit 103 determines in step 303 that the execution job is a job that does not need to be re-executed, or after the registration process in step 304 is completed, the job operation status reference registration unit 103 terminates the execution job. Is performed (step 305), and control is returned to the determination at step 301 to determine whether or not an execution job still exists (if the execution job still exists at the determination at step 301, the same processing as described above is repeated). Is).

On the other hand, the job end priority search means 102
If it is determined in step 301 that there is no “execution job”, the job is not an execution job but information is registered in the job information table 400, and “再” is set in the re-execution necessity information. The re-execution necessity information for the job being executed is updated to “x” (step 306), and control is passed to the existing means for performing system shutdown processing (step 307).

Note that, due to the presence of the processing in step 307, even if a job is registered as “〇” in the re-execution necessity information during system operation, if the job is not an execution job when a power failure occurs, the system At the time of restart, it does not correspond to a “re-execution job”. However, such adjustment relating to the “re-execution job” is performed using a predetermined job (not an execution job when a power failure occurs, but the job information table 40).
0 for which the information is registered and the re-execution necessity information is set to “〇”), based on the fact that the operation status information is not registered in the job operation status file 500, This can also be realized by recognizing that a predetermined job does not correspond to a re-execution job.

Third, the operation at the time of restarting the system will be described with reference to FIG.

After repairing a failure or the like that caused a power failure, the computer 100 executes restart processing of the computer system based on a system restart instruction from the UPS 200.

At the time of such a system restart process, the re-execution job searching means 104 sequentially searches the jobs (registered jobs) whose information is registered in the job information table 400 (for example, in descending order of end priority). ) Extract (Step 40)
1).

Next, the re-execution job search means 104 detects the re-execution necessity information of the registered job extracted in step 401 from the job information table 400 (step 402), and based on the re-execution necessity information, It is determined whether the registered job is a job to be re-executed (re-executed job) from the continuation of the termination time in the previous operation (whether or not "再" is specified in the re-execution necessity information at this time). Yes (Step 40
3). Here, the re-execution job search unit 104 determines in step 403 that “the registered job is not a re-execution job”.
When the determination is made, the determination in step 406 described below is performed.

If it is determined in step 403 that “the registered job is a re-executed job”, the re-executing job execution unit 105 reads from the job operation status file 500 the operation status information for the re-executed job (immediately before the termination). (Step 404), and the re-execution job is started from the continuation of the termination time in the previous operation (Step 405).
Thereafter, the re-execution job execution unit 105 returns control to the re-execution job search unit 104.

The re-execution job search means 104 determines whether or not the above processing has been completed for all registered jobs (step 406). A registered job is extracted (step 401), and the above processing is repeated for the registered job.

On the other hand, the re-execution job search unit 104 determines in step 406 that “the job has been completed for all registered jobs”.
If it is determined, the control is passed to the existing means for performing the system activation processing (step 407).

Next, with reference to FIGS. 5 and 6, a specific example of the automatic job operation method based on the UPS cooperation according to the present embodiment will be described.

Here, as shown in FIG. 6, the following a,
Consider a case where jobs such as b and c exist.
A typical example of a computer system to which the automatic job operation system based on the UPS cooperation of the present invention is applied is a job group of a type as shown in this example (a job for performing a reference process, a job for performing a sort process, and A computer system in which a job for performing a registration process is operated can be cited (this is the same in the second embodiment described later).

A. Job for performing registration processing for adding new data to the user file 600 in which data is registered in advance (JOB001)

B. A job that performs a sort process of re-sorting and updating data based on certain conditions with reference to data in the user file 600 (JOB002)

C. Job (JOB0) that performs a reference process that refers to data registered in the user file 600
03)

In this case, the importance of the reference processing is the least important among the above three processings (registration processing, sort processing, and reference processing). Then, considering whether the common registration process or the sorting process is more important because the writing process is performed on the file (user file 600), "I want to register as much as possible to write data into the file." Since there is a request, the importance of the registration process is greatest (I want to process it to the end). That is, in this example, the end priority of each job is set so that the process is terminated (terminates halfway) in the order of the reference process, the sort process, and the registration process (the end priority is set as shown in FIG. 5). , JOB003, JOB0
02, JOB001).

Assuming the existence of the job group as described above, in the process shown in FIG. 2 (the process of the job information registration unit 101) during the operation of the system, as shown in FIG. Each job (JOB00
1, JOB002, and JOB003), the end priority, the job name, and the re-execution necessity information are registered.

The re-execution necessity information is described below.
In this example, since it is desired to sequentially perform a registration process for writing data and a sorting process based on the data, the job JOB001 for performing the registration process and the job JOB002 for performing the sorting process are “necessary for re-execution. Job "
(“再” is set in the re-execution necessity information for these jobs).

When a power failure occurs, the following processes a to d are performed as the process shown in FIG. 3 (the process of the job end priority search means 102 and the job operation status reference and registration means 103).

A. First, the job end priority search unit 10
2, the job JOB003 having the highest end priority among the three jobs is detected. Then, the job operation status reference registration unit 103 stores the job JOB0
03 is a job that does not need to be re-executed, and the execution of the reference process by the job JOB 003 is terminated as it is.

B. Next, the job end priority search unit 10
2, the job JOB002, which is a job having a higher end priority, among the two jobs being executed is detected.
In this job JOB002, “〇” is designated in the re-execution necessity information. Therefore, the job operation status reference / registration unit 103 acquires that the job information is specified from the job information table 400, and the current job JO
The operation status, file access status, and the like relating to B002 are registered in the job operation status file 500 as operation status information necessary for executing the job from the continuation at the time of system termination at the time of system restart, and the job JOB002.
Is terminated.

C. Finally, job end priority search means 1
The same procedure is performed for the job JOB001 detected by the job operation information 02, and the operation status information is stored in the job operation status file 500 based on the re-execution necessity information (designation of “@”) for the job in the job information table 400. After the registration, the job JOB001 is terminated (discontinuation of the registration process).

D. When there are no more jobs to be executed as described above, the system shutdown processing is performed.

Further, when the system is restarted, the following processes a to c are performed as the processes shown in FIG. 4 (the processes of the re-execution job search unit 104 and the re-execution job execution unit 105).

A. First, the re-executed job search unit 104 searches for jobs (registered jobs) whose information is registered in the job information table 400 in the descending order of end priority.
It is checked whether or not each of the detected registered jobs is a re-execution job (whether or not the re-execution necessity information has "〇" specified).

B. Here, JOB0 for performing the sorting process
02 and the job JOB001 to be registered are re-executed jobs. Therefore, the re-executed job execution unit 105 reads the operation status information of these jobs from the job operation status file 500, and starts from the continuation time of the previous operation. These jobs JOB001 and JOB002 are restarted.

C. Then, after the re-execution job group is activated as described above, a system activation process is performed.

(2) Second Embodiment FIG. 7 is a block diagram showing a configuration of an automatic job operation system by UPS cooperation according to a second embodiment of the present invention.

As in the first embodiment, the automatic job operation method based on UPS cooperation according to the present embodiment also includes a computer 100 that operates under program control and a UPS.
200, a terminal 300, a job information table 400, and a job operation status file 500.

The computer 100 includes a job information registration unit 101, a job end priority search unit 102, a job operation status reference registration unit 103, a re-execution job search unit 104, a re-execution job execution unit 105, And a processing unit 106.

FIG. 8 is a flow chart showing processing when a power failure occurs in the automatic job operation system using the UPS cooperation according to the present embodiment. This processing includes an execution job presence / absence determination step 801, an end priority highest execution job search step 802, an abort processing standby step 803, a re-execution necessity information determination step 804, an operation status information registration step 805, and a job abort. It comprises a processing step 806, a restart necessity information updating step 807, and a system shutdown processing step 808.

FIG. 9 is a diagram showing a specific example of the contents of the job information table 400 in the automatic job operation method using the UPS cooperation according to the present embodiment. This job information table 400
Indicates the end priority, job name, re-execution necessity information, and wait time (WaitTime) for each job.
And

FIGS. 2 and 4 are also flowcharts showing processing during system operation and system restart in the automatic job operation system based on UPS cooperation according to the present embodiment. FIG. 6 is also a diagram for explaining a specific operation of the automatic job operation method based on the UPS cooperation according to the present embodiment.

Next, the operation of the automatic job operation system based on the UPS linkage configured as described above will be described.

The operation of the automatic job operation system based on the UPS cooperation according to the present embodiment, which is different from the operation of the automatic job operation system based on the UPS cooperation according to the first embodiment, is described in the job information table. This is an operation related to the existence of the wait time in 400 and the existence of the waiting time processing means 106. Therefore, here, the description will be made with reference to FIG. 2, FIG. 7, FIG. 8, and FIG. 9 focusing on such an operation unique to the present embodiment. The operation at the time of restarting the system (see FIG. 4) is completely the same as the operation in the above-described first embodiment, and the description thereof is omitted here.

First, an operation during system operation (before power failure occurs) will be described with reference to FIG.

The job information registering means 101
, Instructions and information are input (step 201), and a job information table 400 is created based on the instructions and information (step 202). That is, the job information, the job name, the end priority, the re-execution necessity information, and the wait time are registered in the job information table 400 (see FIG. 9). Here, the wait time of a certain job is defined as the time from the execution of the discontinuation process of the previous job to the start of the execution of the discontinuation process of the job in the process of successively performing the process of terminating the execution job group when a power failure occurs. This indicates information indicating how long to wait (for example, how many seconds).

Second, the operation when a power failure occurs (when a power failure occurs during system operation) will be described with reference to FIG.

When a system shutdown instruction (an instruction for requesting a system shutdown process) is issued from the UPS 200 due to the occurrence of a power failure, the computer 100
While the power is being supplied from the UPS 200, the CPU 200 performs an abort process for the job group being executed, and executes a system shutdown process.

At the time of such a system shutdown process, the job end priority search means 102 selects a job having the highest priority (ie, end priority) to be ended among jobs currently being executed (executed jobs). Search for. That is, it is determined whether there is an execution job (step 8).
01), if it is determined in step 801 that there is an "executed job", the job information table 400 is searched to detect an executed job having the highest end priority (step 802).

Next, the waiting time processing means 106 refers to the wait time value in the job information table 400 for the execution job detected by the job end priority search means 102 in step 802, and terminates the execution job. Is recognized after how many seconds to start, and the cutoff processing is made to stand by (wait) for that time (step 80).
3).

When the waiting time in step 803 elapses, the job operation status reference registration unit 103 stores the re-execution necessity information in the job information table 400 for the execution job detected by the job end priority search unit 102 in step 802. Then, it is determined whether or not the execution job is a “job to be re-executed when the system is restarted” (whether the re-execution necessity information is “Δ” or “x”) (step 804). ).

Hereinafter, the processing of steps 805 to 808 is the same as the processing of steps 304 to 307 in the first embodiment.

Next, with reference to FIGS. 6 and 8, a specific example of the automatic job operation system based on the UPS cooperation according to the present embodiment will be described.

Here, the three jobs (job JOB001 for performing the registration process and job JOB0 for performing the sort process) shown in FIG.
02 and a job JOB003) for performing the reference process.

In this case, during the system operation, the job information registration means 101 registers the end priority, job name, re-execution necessity information, and wait time for each of the above-mentioned jobs in the job information table 400. Is done.

Referring to FIG. 9, the designation of the wait time in the job information table 400 in the present example is such that “after the discontinuation process has been performed for the job JOB003 to perform the reference process, 60 seconds later (wait for 60 seconds). The job JOB002 that performs the sort process is terminated, and the job J0B001 that performs the registration process is started after a lapse of another 20 seconds. "

Assuming the existence of the job information table 400 as described above, when a power failure occurs, the processing shown in FIG. 8 (job end priority search means 102, job operation status reference registration means 103, and wait time processing means 106 As the processing, the following processings a to e are performed.

A. First, the job end priority search unit 10
2, the job JOB003 having the highest end priority among the three jobs is detected. Then, the job operation status reference registration unit 103 stores the job JOB0
03 is a job that does not need to be re-executed, and the execution of the reference process by the job JOB 003 is terminated as it is. Since no wait time is specified for the job, the processing by the waiting time processing unit 106 is not performed.

B. Next, the job end priority search unit 10
2, the job JOB002, which is a job having a higher end priority, among the two jobs being executed is detected.
For this job JOB002, “60 seconds” is set as the wait time. Therefore, the waiting time processing means 106 waits for the job to be sorted to be terminated based on the value of the wait time until the end of the job.
It is recognized that a wait of 0 seconds is necessary, and the wait is performed for that time. In other words, the job termination process of JOB002 starts 60 seconds after the termination process of JOB003 ends. Such designation and processing are effective when it is desired to perform the sorting processing in the currently registered data as much as possible and then terminate the sorting processing.

C. As described above, the waiting time processing means 106
After the wait processing for 60 seconds is performed, the termination processing of the job JOB002 is executed. Here, regarding the job, “に” is specified in the re-execution necessity information. Therefore, the job operation status reference registration unit 10
3, it is acquired from the job information table 400 that the job is specified, and the current job JOB002 is obtained.
The operation status, file access status, and the like are registered in the job operation status file 500 as operation status information necessary to execute the job from the continuation at the time of termination when the system is restarted, and the sort processing by the job JOB002 is terminated.

D. Finally, job end priority search means 1
The same procedure is performed for the job JOB001 detected by “02”, based on the wait time (“20 seconds” designation) and the re-execution necessity information (“情報” designation) for the job in the job information table 400. After the waiting process for 20 seconds, the operation status information is registered in the job operation status file 500, and then the job JOB001 is terminated (the registration process is terminated).

E. When there are no more jobs to be executed as described above, the system shutdown processing is performed.

(3) Third Embodiment FIG. 10 is a block diagram showing a configuration of an automatic job operation system based on UPS cooperation according to a third embodiment of the present invention.

As described above, the present invention has the following effects.

The first effect is that the end priority is added to the job group and the end priority is managed by the job information table, so that when the system is shut down when a power failure occurs, the job as a whole system is processed. That is, it is possible to execute the termination processing of each job in consideration of the operational efficiency. For example, when the processing of the job group is terminated when a power failure occurs, the integrity of use data of the job group can be improved.

The reason why such an effect occurs is that, in particular, the end priority (order of processing termination) of a job that performs writing processing on a file is higher than the end priority of a job that performs other processing (reference processing and the like). If you set it low, UPS
This is because as much data as possible can be written to the file while the power supply from is continued, thereby improving the integrity of the used data and the like.

The second effect is that, since a job that has been interrupted halfway when a power failure occurs can be executed from the continuation of the time when the system is restarted, the operation time of the entire system can be made more efficient. . For example, files that had been registered or sorted halfway through when a power failure occurred will not be processed again from the beginning when the system is restarted, so that those jobs can be operated efficiently. Become.

The reason why such an effect is generated is that the operation status information of the job at the time of the termination can be stored in the operation status file.
