Description

  The present invention relates to a system and method for processing a job according to a load on the system, a computer-readable program for executing the method, and a recording medium storing the program.

  A document management server is used to register a created document as a document file, search for the document file in response to a request for the document file from the user, and provide the document file to the user. The document management server is connected to a network such as the Internet, and can register, search, and transmit a document file in response to a request from a client computer connected to the network.

  When a user acquires a necessary document file using a client computer, a function for searching for the document file is used. For example, a file name of a document file or a term in the document is input as a keyword, and a document file related to it is searched. This requires a considerable amount of time to obtain a search result when there are a large number of document files registered in the document management server, that is, stored. In addition, since there are a large number of related document files with only one keyword input, it may be necessary to input keywords many times. If these search conditions are complicated, more search time is required.

  Even if the search itself does not take time, the system response deteriorates if a large number of document files are registered in the background or if other processes that impose a load on the processor are performed. In such a case, a state in which other processing cannot be executed until a search result is obtained, or a state in which search processing cannot be performed until the other processing ends and a result is returned occurs.

  There has been proposed a document management system and method capable of reducing the time for registering a document and reducing the load on a server when managing documents over the Internet (see Patent Document 1). In this system and method, the load on the server is reduced by shifting the data transfer from the client machine to the server machine and the data registration processing timing on the server machine, and starting the registration at a time when the server load is low. , Reduce processing time. Specifically, registration timings such as “immediate registration”, “later registration”, and “night registration” are designated, and at the same time, the data file is transferred to the server, and registration is executed according to the designated timing.

In this system and method, the server load can be reduced by specifying a time zone with a low server load. However, if multiple users specify "Register Immediately" at the same time, this specification overlaps and the server load is reduced. May become larger. In this system, the registration status screen can be used to check the registration status and specify a time period when there is little processing to perform registration, but to confirm processing other than registration processing executed in the background. Therefore, the server load cannot always be reduced.

Furthermore, not only the user but also the system administrator can change the priority for each user and adjust the system load.

  The present invention will be described in detail with reference to the drawings, but the present invention is not limited to the embodiments shown in the drawings. First, a configuration of a network system including a job processing system of the present invention will be described with reference to FIG. A network system 10 shown in FIG. 1 is connected to a network 11 such as the Internet or an intranet, a document management server 12 that is connected to the network 11 and implements a job processing system, and is also connected to the network 11 and manages documents via the network 11. It comprises a plurality of clients 13 that communicate with the server 12. Here, a network system 10 configured as a document management server 12 that manages document files and a plurality of clients 13 is disclosed.

  The document management server 12 receives a processing request from the client 13 and returns a processing result to the client 13. For example, processing for registering a created document as a document file, processing for searching a registered document file, processing for searching and converting an image of a downloaded document, etc. are received, processing for that request is performed, Returns the processing result. The client 13 generates a request as described above from information input by the user, transmits the request to the document management server 12, and receives the processing result from the document management server 12.

  The client 13 may be any client as long as it can generate and transmit a processing request and receive a processing result. In addition to a personal computer, the printer 13 includes a printer, a facsimile apparatus, a copying apparatus, and a scanner having a communication function. It can be a device, a digital multi-function peripheral including these, or the like. The same document management server 12 can be used.

  Specifically, a communication device including a network adapter, a modem, and a proxy server necessary for performing communication via the network 11, a memory necessary for storing a document file, a storage device such as a hard disk drive, registration processing, A processor that executes a search process is included. Registration processing and search processing can be performed by the processor executing a program, and the program is stored in the storage device and read and executed as necessary.

  The job processing system of the present invention will be described in detail with reference to FIG. A job processing system 20 shown in FIG. 2 is implemented in the document management server shown in FIG. 1, and includes a system load monitoring unit 21, a threshold storage unit 22, a determination unit 23, a job management unit 24, a processing request storage unit 25, A priority storage unit 26, a job processing unit 27, a document file storage unit 28, and a message transmission / reception unit 29 are included. The job processing system may be the document management server itself.

  The system load monitoring unit 21 monitors the load on the server. The server load can be obtained from the processor usage rate, the memory usage rate, the number of users connected to the server, the response time of basic operations on the server, and the like. For example, the processor usage rate and the memory usage rate can be monitored by a system monitor executed on the operating system. The response time of the basic operation is, for example, for a login operation (transmission of user ID and password) from the document management client, receiving the user ID and password, checking whether they match, and notifying that the user has logged in or logging in It can be a response time until a notification that it is not possible is returned.

  The threshold storage unit 22 stores a threshold related to the server load. Data such as 70% for the processor usage rate and memory usage rate, for example 30 users for the number of users, and 5 minutes for the response time are stored as threshold values. These values can be set appropriately by the server administrator. In addition to these, it is possible to include a time period during which the load on the server is empirically high. In the present invention, when all the threshold values are not exceeded and the range of the threshold values is satisfied, real-time processing can be performed, or only a specific threshold value is determined to determine whether to perform synchronous processing or asynchronous processing. You can also. The threshold storage unit 22 can be configured as a part of the memory or hard disk drive.

  In the embodiment shown in FIG. 2, a message transmission / reception unit 29 that transmits and receives a processing request and a processing result is provided. The message transmitting / receiving unit 29 corresponds to the communication device. The message transmission / reception unit 29 receives processing requests for document registration, document search, and the like in addition to receiving the above user ID and password and log-in notification, and transmits a processing result for the processing request.

  Here, FIG. 3 illustrates a processing request, and FIG. 4 illustrates a data structure of the threshold storage unit 22, which will be described in detail. The processing request includes a processing request ID field 300 for identifying the processing request, a location information field 301 of the client that transmitted the processing request, a priority field 302 indicating the execution priority of the processing request, and a job content field 303. It is comprised including. The processing request ID field 300 includes information for the client to identify the processing request. The client location information field 301 includes location information such as an IP address and a Mac (Media access control) address. This location information can be used to return the processing result to the appropriate client.

  The priority field 302 includes priority information set by the user, and includes, for example, any of three levels of information such as “high”, “medium”, and “low”. The job content field 303 includes information indicating processing content such as document registration and document search. For document registration, information indicating document registration, a document name, and a document file are included. For document search, information indicating document search, a search keyword such as a document name is included.

  The data structure of the threshold value storage unit 22 includes a condition ID field 400 for identifying each condition, a determination condition field 401, a threshold value field 402, and a processing method field 403. The condition ID field 400 includes identification information that can identify a condition, and can be numbers such as “1”, “2”,... As shown in FIG. The determination condition field 401 indicates a server load condition, and includes conditions such as “CPU usage rate exceeds a threshold value” and “Server connection user count exceeds a threshold value”. In addition, when a time zone is used as a threshold, a condition such as “whether it is a threshold time zone” or a priority such as “whether the priority is a threshold” can be included.

  The threshold value field 402 includes a setting value used for determining whether to perform synchronous processing or asynchronous processing. This setting value can be set as appropriate by the server administrator. As shown in FIG. 4, the CPU usage rate can be set to 70%, and the number of users can be set to 30 users. The time zone can be set, for example, from 10:00 to 15:00 when there are many accesses to the server. Further, when the priority is used, for example, “high” can be set. In the processing method field 403, either synchronous processing (real-time processing) or asynchronous processing is set, and the information is stored.

  Referring to FIG. 2 again, the determination unit 23 receives the processing request received by the message transmission / reception unit 29 and accesses the system load monitoring unit 21 and the threshold storage unit 22. From the system load monitoring unit 21, load information related to the server load such as a processor usage rate, a memory usage rate, and the number of users when a processing request is received is acquired. Further, the threshold storage unit 22 reads and acquires thresholds such as the processor usage rate, the memory usage rate, and the number of users. The determination unit 23 compares the server load information acquired from the system load monitoring unit 21 with a threshold value, and determines whether or not the threshold value is exceeded.

  If the threshold is exceeded in this determination, the current server load is large. Therefore, the processing request is processed asynchronously, for example, when the server load is later reduced, and if the threshold is not exceeded, the current server load is processed. Is small, the processing request is processed synchronously, that is, in real time.

  When the determination unit 23 determines that the threshold value is exceeded, the job management unit 24 receives a processing request and stores it in the processing request storage unit 25. Here, the processing request storage unit 25 is configured separately from the job management unit 24, but may be included in the job management unit 24. In this case, the job management unit 24 may hold the processing request. it can. The job management unit 24 sends a reception message indicating that the processing request has been received to the message transmission / reception unit 29 together with the storage of the processing request. The processing request storage unit 25 is queued, and generally sends a processing request to the job processing unit 27 so as to process a job that has been input first. In the embodiment shown in FIG. 2, priorities are preset in relation to jobs, and priority information related to the priorities is stored in the priority storage unit 26. The priority storage unit 26 may also be included in the job management unit 24, and can retain priority. The priority storage unit 26 and the processing request storage unit 25 can also be configured as a part of the memory and the hard disk drive, similarly to the threshold storage unit 22.

  Here, the data structure of the processing request storage unit 25 will be described with reference to FIG. The processing request storage unit 25 is configured as a table including a job ID field 500, a job priority field 501, a status field 502, a client name field 503, a processing request field 504, and a processing result field 505. . When the determination unit 23 determines that the threshold value is exceeded, the job management unit 24 sequentially receives processing requests, and job IDs are associated in that order and stored in the job ID field 500. The job ID can be a job number that can identify the job. In the embodiment shown in FIG. 5, job numbers 97 to 100 are set, and these jobs are waiting for transmission of processing results and waiting for processing.

  The priority field 501 stores information indicated by three levels of “high”, “medium”, and “low” according to the priority of the job. The status field 502 stores information indicating whether the job is completed, being processed, or not completed. All processing requests that have not been issued to the job processing unit 27 are incomplete jobs. The status in the status field 502 is changed to information indicating completion when processing of a job indicating processing is completed, and is changed to information indicating processing when processing of a job indicating incomplete is started. The client name field 503 stores identification information for identifying the client communicating with the server. In the embodiment shown in FIG. 5, the client name is used, but it may be an IP address, a Mac address, or the like. The client name is associated with location information such as an IP address and a Mac address.

  The processing request field 504 stores information indicating job contents such as search and registration. In the embodiment shown in FIG. 5, the processing request set in the job number 97 requests a search process and requests to search using “minutes” as a search keyword. The processing request set in the job number 98 requests registration processing, and requests to store the file “YYYY” with the document name “XXXX”. In the processing result field 505, a processing request is issued to the job processing unit 27 and the processing result is stored. Since the information stored in the status field 502 indicates completion for the job with the job number 97, the processing result is stored in the processing result field 505. For other jobs, the status in the status field 502 is being processed or has not been completed, so the processing result is not stored and is blank. The processing result of job number 97 stores information “result 3 hits ...” indicating that 3 related document files have been hit.

  Referring to FIG. 2 again, the job management unit 24 sequentially retrieves processing requests from the processing request storage unit 25 while referring to the priority storage unit 26 and issues them to the job processing unit 27. As described above, the processing request storage unit 25 is a queue that processes a job that has been input first, but the job management unit 24 refers to the priority storage unit 26 and has a high priority. The job is preferentially taken out and issued to the job processing unit 27. When information regarding priority is included in the processing request, the priority storage unit 26 extracts the priority information when the processing request is stored by the job management unit 24, and the processing request Store it in association with. Also, the user can set a priority in advance according to the type of job such as document registration or document search, and can store the priority in the priority storage unit 26 in association with the job. Instead of being determined and preset by the user, a priority determination unit may be provided. The priority determination unit is set to determine the priority according to the type of job, and is issued to the job processing unit 27 when the job management unit 24 stores the processing request in the processing request storage unit 25. At this time, the priority of each processing request can be determined and issued to the job processing unit 27 according to the priority.

  Further, the priority storage unit 26 can also store the priority for each user, so that the processing request of the managerial employee can be compared with the processing of the managerial employee compared to the processing request of the general employee. The processing request of the officer can be processed with priority compared to the request. In addition, the user may freely determine the priority, separately from the processing request, the priority setting information is transmitted, and the priority determination unit receives the priority setting information, and the priority is based on the information. Can be determined and stored in the priority storage unit 26. In addition, the administrator of the document management server that implements the job processing system can change the priority instead of the user. In this case, a priority changing unit is provided, and the administrator can input priority changing information. In response, the priority changing unit changes the priority, and the priority is stored in the priority storage unit 26.

  The priority can be set to “high”, “medium”, and “low” from the highest priority. In other words, a job with a high priority is processed preferentially compared to a medium or low job, and a medium job is preferentially compared to a low job. It is processed. For example, the same “medium” items are processed in the order in which they are first placed in the processing request storage unit 25. In the present invention, the priority setting values are not limited to these three levels, and may be five levels such as “high / high”, “high”, “medium”, “low”, and “low / low”. Alternatively, there may be 10 levels of “10” to “1”.

  The data structure of the priority storage unit 26 will be described with reference to FIG. The priority storage unit 26 includes a target field 600 and a priority field 601. The target field 600 includes a client name, job content, and the like, and information such as “high”, “medium”, and “low” is stored in the priority field 601 according to them. Specifically, as shown in FIG. 6, the target field 600 stores user names A and B as client names, document registration and job search as job contents. In the embodiment shown in FIG. 6, when the user A transmits a processing request, since the priority is “high”, the processing is performed with priority, and when the user B transmits a processing request, Since the priority is “low”, the request is processed after the processing requests with the priority “high” and “medium” are processed. Further, since the document registration is set to “low” and the document search is set to “medium”, the processing request including the document search is processed before the processing request including the document registration. Note that since the client names such as user A and user B are set in the target field 600 first, the priority of the same priority, for example, “high” is determined according to the priority of the job content. The

  Referring to FIG. 2 again, when the determination unit 23 determines that the threshold value is not exceeded, the determination unit 23 instructs the message transmission / reception unit 29, and the job processing unit 27 receives a processing request from the message transmission / reception unit 29. Upon receiving the processing request, the job processing unit 27 processes the processing request in real time. The job processing unit 27 is connected to the document file storage unit 28. If the job is a document search, the job processing unit 27 searches the document file storage unit 28 for a document file related to a keyword or the like included in the processing request. As a result of processing, the job processing unit 27 transmits the search result to the message transmitting / receiving unit 29 here. When the message transmission / reception unit 29 receives the search result, the message transmission / reception unit 29 transmits the search result based on the location information of the client included in the processing request. The search results can be the number of related document files, their file names and document names, and document files. A document name can be transmitted as a search result, and a document file can be transmitted in response to a download request.

  In addition to the real-time processing described above, the job processing unit 27 processes the issued processing request in response to the issuance of the processing request from the job management unit 24. The job management unit 24 issues processing requests according to the server load, and is executed when the load does not exceed the threshold. Therefore, it is executed when the server load does not exceed the threshold value stored in the threshold value storage unit 22.

  In addition, by causing the processor to execute a program stored in the storage device, the system load monitoring unit 21, the determination unit 23, the job management unit 24, and the job processing unit 27 can be caused to function.

  Next, an embodiment of processing executed by the job processing system will be described with reference to FIG. First, a user inputs a search keyword to the document management client, and generates a processing request such as search processing. When the user transmits a processing request to the document management server by pressing a transmission button or the like, the document management server starts processing the processing request (S700). The job processing system implemented in the document management server or the document management server itself receives the processing request transmitted from the client by the message transmission / reception unit 29 (S701). The message transmission / reception unit 29 notifies the determination unit 23 that the processing request has been received. The determination unit 23 acquires load information related to the current server load from the system load monitoring unit 21 and reads the threshold value from the threshold value storage unit 22. (S702). The load information related to the server load includes the current CPU usage rate, memory usage rate, the number of users connected to the server, and the like.

  The determination unit 23 compares the acquired current server load information with a threshold value, and determines whether the server load exceeds the threshold value (S703). When it exceeds, asynchronous processing is selected, and when it does not exceed, synchronous processing is selected. In this way, it is determined whether or not asynchronous processing is executed. When asynchronous processing is executed, a processing request is sent to the job management unit 24, and the processing request is stored in the processing request storage unit 25 (S704). The processing request is associated with a job ID, information about the client is stored in the client name field, and information indicating incomplete is stored in the status field. The job management unit 24 generates a reception message indicating that the processing request has been received, and sends it to the message transmission / reception unit 29 together with the job ID. The job ID is identification information for identifying a job, and is used for identifying a processing result for each processing request when one client transmits a plurality of processing requests. The message transmitting / receiving unit 29 transmits the received message together with the job ID to the client (S705).

  When the asynchronous processing is not executed, a processing request is sent to the job processing unit 27, the job processing unit 27 performs real-time processing, and the processing result is sent to the message transmitting / receiving unit 29 (S706). The message transmission / reception unit 29 transmits the received processing result to the client (S707). When the client receives the reception message or the processing result, the processing for the processing request transmitted by the client ends (S708). In this case, since the processing is performed in real time, it is not necessary to associate the job ID for identifying the job, but the job ID can be transmitted together with the processing request ID.

  With reference to FIG. 8, the asynchronous processing executed in S704 and S705 shown in FIG. 7 will be described in detail. When it is decided to execute the asynchronous process, the asynchronous process is started (S800), and the job management unit 24 periodically polls the processing request storage unit 25 to check the status (S801). Polling inquires whether a processing request is stored in the processing request storage unit 25. When a processing request is stored by polling, the status stored in association with the processing request is confirmed.

  It is determined whether or not there is a status of “incomplete” (S802). If there is no “incomplete”, it is determined whether there is a status of “completed” (S803). The status is one of “incomplete” in which the process is not executed, “in process” in which the process is currently executed, and “completed” in which the process is executed and completed. If there is an “incomplete” item, an “incomplete” processing request is taken out and issued to the job processing unit 27 (S804). The job processing unit 27 starts processing the processing request asynchronously, that is, not in real time, for example, when the subsequent server load does not exceed the threshold (S805). When the processing is started, the job management unit 24 changes the status corresponding to the processing request in the processing request storage unit 25 from “incomplete” to “processing” (S806). As indicated by the broken line, the job processing unit 27 executes the job asynchronously (S807) and sends the result to the job management unit 24. The job management unit 24 stores the result as the processing result of the processing request storage unit 25, and changes the status from “processing” to “completed” (S808).

  If no status is “completed” in S803, the asynchronous process ends (S809). Even after the asynchronous processing is completed, the job management unit 24 periodically performs the polling of S801. If the status is “incomplete”, the process proceeds to S804, and if not, the process proceeds to S803, and the respective processes are repeated. During this time, when the job being processed ends, the processing result is stored as in S808, and the status is changed to “completed”.

  If the status is “complete” in S803, the job management unit 24 extracts the processing result from the processing request storage unit 25, and sends the processing result to the message transmission / reception unit 29 together with the job ID in order to return the processing result to the client. (S810). When the message transmission / reception unit 29 receives the processing result, the message transmission / reception unit 29 transmits the processing result based on the position information of the client to the client that transmitted the processing request (S811). In response to the message transmission / reception unit 29 transmitting the processing result to the client, the job management unit 24 stores the job ID, status, client name, processing request, processing result regarding the processing request stored in the processing request storage unit 25. Is deleted (S812).

  With reference to FIG. 9, another embodiment of processing executed by the job processing system will be described. The client starts a processing request (S900), and the message transmission / reception unit 29 receives the processing request (S901). The message transmission / reception unit 29 notifies the determination unit 23 that the processing request has been received, and the determination unit 23 acquires load information regarding the current server load from the system load monitoring unit 21 and reads the threshold value from the threshold storage unit 22. (S902). The determination unit 23 compares the acquired current server load information with a threshold value, and determines whether or not the server load exceeds the threshold value (S903). When it exceeds, asynchronous processing is selected, and when it does not exceed, synchronous processing is selected. In this way, it is determined whether or not asynchronous processing is executed. When asynchronous processing is executed, a processing request is sent to the job management unit 24, and the processing request is stored in the processing request storage unit 25 (S904). The processing request is associated with a job ID, information about the client is stored in the client name field, and information indicating incomplete is stored in the status field. In this embodiment, priority information is also stored in the priority field. The priority information can be acquired by the job management unit 24 by being included in the processing request, determined by the priority determination unit, or input by a user or an administrator. The job management unit 24 generates a reception message indicating that the processing request has been received, and sends the reception message to the message transmission / reception unit 29 together with the job ID. The message transmission / reception unit 29 transmits the received message together with the job ID to the client (S905).

  When the asynchronous processing is not executed, a processing request is sent to the job processing unit 27, the job processing unit 27 processes the result, and the result is sent to the message transmission / reception unit 29 (S906). The message transmission / reception unit 29 transmits the received processing result to the client (S907). When the client receives the reception message or the processing result, the processing for the processing request transmitted by the client ends (S908).

  With reference to FIG. 10, the asynchronous process executed in S904 and S905 shown in FIG. 9 will be described in detail. When it is decided to execute asynchronous processing and asynchronous processing is started (S1000), the job management unit 24 periodically polls the processing request storage unit 25 to check the status (S1001). Here, since the priority is included, the statuses are checked in the order of priority “high”, “medium”, and “low”.

  The subsequent processing is the same as the flowchart shown in FIG. That is, it is determined whether there is a status of “incomplete” (S1002). If there is no “incomplete”, it is determined whether there is a status of “completed” (S1003). The status is one of “incomplete” in which the process is not executed, “in process” in which the process is currently executed, and “completed” in which the process is executed and completed. If there is an “incomplete” item, an “incomplete” processing request is taken out and issued to the job processing unit 27 (S1004). Here, the extracted processing requests are extracted in order of priority. For this reason, although a job having a high priority is stored in the processing request storage unit 25 later, it is processed first to implement interrupt processing.

  The job processing unit 27 starts processing the processing request asynchronously, that is, not in real time, for example, when the subsequent server load does not exceed the threshold (S1005). When the processing is started, the job management unit 24 changes the status corresponding to the processing request in the processing request storage unit 25 from “incomplete” to “processing” (S1006). As indicated by the broken line, the job processing unit 27 executes the job asynchronously (S1007), and sends the result to the job management unit 24. The job management unit 24 stores the result as a processing result of the processing request storage unit 25, and changes the status from “processing” to “completed” (S1008).

  If no status is “complete” in S1003, the asynchronous process ends (S1009). Even after the asynchronous processing is completed, the job management unit 24 periodically performs the polling of S1001. If there is a status of “incomplete”, the process proceeds to S1004. If not, the process proceeds to S1003, and each process is repeated. During this time, when the job being processed ends, the processing result is stored as in S1008, and the status is changed to “completed”.

  If the status is “complete” in S1003, the job management unit 24 extracts the processing result from the processing request storage unit 25, and sends the processing result to the message transmission / reception unit 29 together with the job ID in order to return the processing result to the client. (S1010). When the message transmission / reception unit 29 receives the processing result, the message transmission / reception unit 29 transmits the processing result based on the position information of the client to the client that transmitted the processing request (S1011). In response to the message transmission / reception unit 29 transmitting the processing result to the client, the job management unit 24 stores the job ID, status, client name, processing request, processing result regarding the processing request stored in the processing request storage unit 25. Is deleted (S1012).
