In this embodiment, the print transmission unit may select some print destination candidates from a plurality of print destination candidates according to a predetermined print condition, or select one specific print destination candidate. Also good. For example, the print transmission unit counts the number of printed sheets (the number of sheets that are actually printed and output instead of the number of pages in the document) for each printing destination candidate, and the number of sheets is a plurality of prints. Printing destination candidates may be selected based on the number of sheets to be printed this time so that the destination candidates are as uniform as possible.

  In one embodiment, the document management system prepares a log file preparation unit that prepares a log file for the job represented by the job definition information, and a job execution log that is a log related to the job execution result represented by the job definition information. The information processing apparatus may further include a job execution log recording unit for recording, and a log file providing unit for providing the client terminal with information regarding a log file in which the location information of the document storage area and the job execution log are recorded. “Information about log file” is information for the client terminal to know the contents of the log file. Specifically, for example, the log file itself may be the path name to the log file. May be. The prepared log file may store document storage area location information (for example, a document storage destination path name to be described later). The log file may be prepared in a prepared document storage area (a document storage area corresponding to a job).

  In one embodiment, the document management system can be composed of one or more document creation servers and document management servers. The document creation server can include the job control unit and a document creation unit (for example, an application program) that creates one or more documents by executing a job represented by job definition information. The job control unit sends a path name request that is a request for a document storage destination path name to the document management server, and a document specified from the document storage destination path name received in response to the path name request. And a document storage control unit that instructs the document creation unit to store one or more documents in the storage area. The document management server can include the job identification information determination unit, a path name creation unit, a storage area securing unit, a path name transmission unit, and the job / document correspondence management unit. In response to the path name request from the document creation server, the path name creation unit writes the document storage destination path for writing the document from the document creation server that sent the path name request to the document storage area uniquely associated with the job. A name can be created. The storage area securing unit can secure a document storage area in a location accessible from the transmission source document creation server using the document storage destination path name. The path name transmission unit can transmit the created document storage destination path name to the document creation server of the transmission source.

  In this embodiment, each time a path name request is received, the path name creation unit updates the first path name element value (for example, a number), and prepares a fixed second path name element value prepared in advance. A document storage destination path name (for example, a network directory path name to be described later) including the first path name element value arranged behind can be created. A fixed second path name element value may be prepared for each business.

  Further, in this embodiment, the document storage control unit stores one or more dummy documents in the document storage area specified from the received document storage destination path name, and the document creation unit creates one or more created documents. The document may be overwritten with one or more dummy documents.

Each unit can also be realized by hardware (for example, a circuit), a computer program, or a combination thereof (for example, a part is executed by a computer program and a part is executed by a hardware circuit). Each computer program can be read from a storage resource (for example, memory) provided in the computer machine. The storage resource can be installed via a recording medium such as a CD-ROM or DVD (Digital Versatile Disk), or can be downloaded via a communication network such as the Internet or a LAN.

  Hereinafter, a computer system including a document management system according to an embodiment of the present invention will be described in detail with reference to the drawings.

  <Configuration of entire computer system>.

  FIG. 1 shows a configuration example of a computer system according to an embodiment of the present invention.

  A telnet terminal 210, an automatic schedule terminal 220, a plurality of document creation servers 200, a plurality of document creation servers 300, a document management server 100, and a network file system 400 are connected to the first communication network 201. . The document management server 100 and a plurality of output servers 500 are connected to the second communication network 202. Each output server (for example, print server) 500 is connected to one or more output devices (for example, printers) 510. As the first and second communication networks 201 and 202, for example, a LAN (Local Area Network) can be adopted, but not limited thereto, other types of communication networks may be adopted. The first and second communication networks 201 and 202 may be a single communication network.

  A plurality of document creation servers 200 and 300 and the document management server 100 constitute a document management system. The telnet terminal 210 and the automatic schedule terminal 220 described above are client terminals that request the server system to create a document (that is, send a job). The telnet terminal 210 creates a job in response to an operation from the user and transmits it to the document creation server 200 or 300. The automatic schedule terminal 220 creates a job and sends it to the document creation server 200 or 300 when a predetermined time comes according to a preset schedule. The job to be transmitted is defined by a job control language (JCL: Job Control Language) 700 illustrated in FIG. 7, and the job control language 700 is transmitted from the telnet terminal 210 or the automatic schedule terminal 220 to the document creation server 200 or 300. As a result, a job according to the job control language 700 is executed. A plurality of at least one of these client terminals 210 and 220 may exist, and a document creation job may be submitted to the document creation server 200 or 300 at the same time. The submitted job is processed by the document creation server 200 or 300 that is the job transmission destination. If the document creation server 200 or 300 is a cluster system, the input / output file is shared, so the transmission is performed. It may be executed not only by the previous document creation server 200 or 300 but also by another server 200 or 300. In the present embodiment, the plurality of document creation servers 200 and 300 and the document management server 100 are shared by the plurality of document creation servers 200 and 300 in order to centrally manage the plurality of document files created by the plurality of document creation servers 200 and 300, respectively. A network file system 400 is prepared. The network file system 400 is a file system provided in an external storage device that can exchange data via the first communication network 201. The network file system 400 includes a document management area 410 and a document management index 420. The document management area 410 is an area for storing a document file created by executing a job. The document management index 420 is information having the same contents as a document index table 910 described later, and is, for example, a file format of the document index table 910. Thereby, for example, even if the document management server 100 is down, the document index table 910 can be restored using the document management index 420.

  In this embodiment, the server system is a so-called multi-platform environment. Specifically, the types of document creation servers 200 and 300 are different. The document creation server 200 is composed of a cluster-connected UNIX (registered trademark) server, and shares a file system so that other document creation servers 200 can also create a document. On the other hand, the document creation server 300 is a PC (Personal Computer) server. Therefore, the document creation server 300 cannot be handled in the same manner as the UNIX server. However, several protocols for sharing the file system are disclosed, and NFS ( By using a file system that can be handled by any OS in the form of Network File System (CIFS) or Common Internet File System (CIFS), an environment in which input data and output documents can be shared is provided. The document creation servers 200 and 300 will be described in detail later.

  The document management server 100 is a computer having a CPU and storage resources (for example, a memory). For example, a document index table 910 and an output destination management table 940 are stored in the storage resource. The storage resources include computer programs executed by the CPU, such as a network name creation unit 110, a document management area securing unit 120, a document attribute setting unit 130, a log creation unit 140, a network name return unit 150, and Web processing. 160, a print instruction reception unit 170, a print transmission unit 180, a backup unit 920, and a load distribution unit 930 are stored. In addition, the network name creation unit 110, the document management area securing unit 120, the document attribute setting unit 130, the log creation unit 140, the network name return unit 150, the web processing unit 160, the print instruction reception unit 170, the print transmission unit 180, and the backup unit The 920 and the load distribution unit 930 can also be realized by hardware such as an integrated circuit as a processing unit that performs each process. In the following description, when a computer program is the subject, it is assumed that processing is actually performed by a CPU that executes the computer program. When each processing unit is realized by hardware, each processing unit mainly performs each process.

  A backup file system 800 is a file system that can be used by the document management server 100. The backup file system 800 is a file system in a storage device outside (or inside) the document management server 100 and is used as a backup destination for document files in the network file system 400. As a backup method, for example, the document creation server 200 or 300 locks a document file being created in the network file system 400, and the backup unit 920 updates an unlocked document file (update) in the network file system 400. Can be employed to read the document file) and back it up to the backup file system 800. As a result, it is possible to prevent the incomplete document file from being backed up.

  <Description of Configuration of Document Index Table 910 and Values Recorded therein>

  FIG. 2 shows a configuration example of the document index table 910.

  In the document index table 910, a work ID 912, a job ID 901, a DD name 902, a DD parameter (creator 903, distribution destination 904, and importance 905) and a network name 906 are recorded for each document file to be created. The The DD name 701 in the job control language 700 (see FIG. 7) is set as the DD name 902 in the document index table 910, and the DD parameters (creator 703 (for example, USER1), distribution destination 704 (for example, A), and importance level) 705 (for example, 1)) is set as 903, 904, and 905. The business ID 912 may be a business ID registered in the job control language 700 and set with a business ID recorded in the job control language 700.

JOB
As the ID 901, a job identification number 907 shown in FIG. 3 is recorded. The job identification number 907 corresponds to a count value indicating the number of jobs to be executed. That is, each time the job identification number 907 is referred to, the number is incremented by one. The referred job identification number 907 (that is, the job identification number 907 at the time of reference) is registered in the document index table 910 as the job ID 901, and then the job identification number 907 is incremented by one. In other words, in this embodiment, a job is executed by the plurality of document creation servers 200 and 300, but the job identification number 907 is a unique number (a unique number in the plurality of jobs executed by the plurality of document creation servers 200 and 300 ( Number that does not overlap).

  The “network name” in the present embodiment is not a name of a communication network but a name uniquely corresponding to a created document file. Specifically, a path name from the document management server 200 or 300 (for example, URL). The network name 906 is acquired by the processing shown in FIG. The network name 906 has a configuration of “current prefix / JOB ID / file name 702 recorded in the job control language 700” from the head to the tail. The current prefix is a fixed value used to create the network name 906. For example, in the storage resource of the document management server 100, a current prefix management table 911 as illustrated in FIG. 13 is stored. In the table 911, a work ID 912 and a current prefix 908 are registered for each of a plurality of works. ing. The network name creation unit 110 can acquire the current prefix 908 corresponding to the business ID by referring to the table 911 using the business ID included in the analysis result of the job control language 700 as a key. Further, the number indicated by the job identification number 907 in FIG. 3 can be acquired as the JOB ID. The network creation unit 110 can create a network name 906 representing a file storage destination by combining the acquired current prefix 908, the JOB ID, and the file name 702 recorded in the job control language 700. it can. The created network name 906 is registered in the document index table 910 in FIG.

  According to the example of the table 910 in FIG. 2, it can be seen that two jobs are executed for the same business (business ID: 489). Each job stores information 1 and 2 for identifying the job as JOB ID 901. It can be seen that the job with JOB ID: 1 has three document files, and the names “DATA1”, “DATA2”, and “OUT3” are defined as job definitions. The creator of these three documents is “USER1”, the distribution destination of the document file corresponding to “DATA1” is “A”, and the distribution destination of the document file corresponding to “DATA2” is “B”. It can be seen that the distribution destination of the document file corresponding to “DATA3” is “C”. The importance should be output with priority as the number is younger. Document files corresponding to “DATA1” and “DATA2” are to be distributed with priority. However, document files corresponding to “OUT3” should be distributed after document files corresponding to “DATA1” and “DATA2”. It can be seen that it is. In the present embodiment, the number of rows in the document index table 910 increases as the number of jobs increases. After a document file corresponding to a certain row is output from the output device 510, the corresponding document file is deleted. By deleting the corresponding lines, it is possible to prevent the document file and the lines (lines in the document index table 910) from increasing infinitely.

  <Configuration of output destination management table 940>.

  FIG. 8 shows a configuration example of the output destination management table 940.

  This table 940 is connected in advance to a distribution destination 941 that is an identifier of the distribution destination, an output server 942 that is information indicating an address on the network of the output server 500 corresponding to the distribution destination 941, and the output server 500. An output device 943 that is an address to the output device 510 is defined. That is, each distribution destination is defined. For each distribution destination, the number of pages 944 that is information indicating the number of sheets printed at the distribution destination is recorded.

  The example of FIG. 8 is an example in which the distribution destinations 941 are “A”, “B”, and “C”, and are associated with job control languages. Since “server1”, “server2”, and “server3” of the output server 942 are host names on the network, there is no problem even with IP addresses. The output device 943 is an identifier indicating a port name on the output server 500, and is an address to the actual output device. The page number 940 is updated by the print transmission unit 180. The print transmitting unit 180 can update the number of pages 940 by specifying the number of prints based on the number of pages and the print conditions for the document file to be printed. For example, if the number of pages of a document file to be printed is 100, and printing is performed for two pages per sheet and single-sided printing is performed, the number of pages as the number of prints is 50.

  In the present embodiment, the output device 510 having a small number of pages is preferentially selected. Thereby, the number of pages 940 can be made as uniform as possible. This is because, if the output device 510 is a printer device, in general, when a certain number of sheets are printed, a piece of paper is generated and operator intervention occurs (for example, it is necessary to manually replenish paper). Since it is possible to replenish the sheet at the same time if the output device 510 of the same type is used so that no operator intervention occurs, an effect of improving the working efficiency of the operator can be expected. Note that the page number 940 may be reset periodically or irregularly. Specifically, for example, if the output device 510 performs the load distribution so as to eliminate the time for pausing the output rather than replenishing the paper at a low speed, the count of the number of pages 940 is set to, for example, 10 Processing such as resetting in minutes may be performed.

  When the document file has an attribute such as importance 905 as described with reference to FIG. 2, a document with high importance is output earlier to the same output device 510. For example, in FIG. 2, regarding JOB ID: 2, there are two documents with DD names “DATA1” and “DATA2” at the distribution destination “B”. At this time, since the distribution destination of “B” is an example of one location in FIG. 8, two documents cannot be output simultaneously. At this time, the document file corresponding to “DATA1” having high importance is output first, and then the document file corresponding to “DATA2” is output.

  <Configuration of Document Creation Servers 200 and 300>.

  FIG. 4 shows a configuration example of the document creation servers 200 and 300. Although processing is different between the UNIX server 200 and the PC server 300, the same configuration can be adopted as the configuration. Hereinafter, the document creation server 200 will be described as a representative example.

  A communication interface (for example, a LAN controller) 231 for performing communication via the first communication network 201, a processor (CPU) 232, and a memory 233 are provided. The memory 233 stores, for example, a telnet process 260, a schedule agent 250, an application program 234, and a job management program 240 as computer programs executed by the processor 232.

  The telnet process 260 receives an input of the job control language 700 from the telnet terminal 210. The schedule agent 250 receives an input of the job control language 700 from the automatic schedule terminal 220. The job control language 700 received by these computer programs is input to the job management program 240, and the job management program 240 causes the application program 234 to execute a job defined in the job control language 700. That is, the job management program 240 becomes a filter existence logically interposed between the telnet process 260 and the schedule agent 250 and the application program 234.

  The job management program 240 includes a job control language analysis unit 241, a network name acquisition unit 242, a file creation unit 243, an application management unit 244, a file release unit 245, and a log acquisition unit 246 as computer program modules. These program modules will be described in detail later. The job control language analysis unit 241, the network name acquisition unit 242, the file creation unit 243, the application management unit 244, the file release unit 245, and the log acquisition unit 246 are integrated as a processing unit that performs each process. It can also be realized by hardware. When each processing unit is realized by hardware, each processing unit mainly performs each process.

  <Flow of processing executed in document management system in this embodiment>

In the present embodiment, the document management system, for example,
1: Job control language analysis processing,
2: Network name acquisition processing and document management area securing processing,
3: File creation processing,
4: Application management processing
5: Log acquisition processing,
Is executed. Hereinafter, each process will be described. In the description of this processing, the operation of each computer program described above will be described.

  (1: Job control language analysis process).

  In response to the job control language 700 being input to the job management program 240, the job control language analysis unit 241 analyzes the job control language 700 and provides information indicating the analysis result (hereinafter, analysis result information). To the network name acquisition unit 242. The analysis result information includes a DD name 701 identified from the job control language 700, a DD parameter (creator 703, distribution destination 704, and importance 705), a file name 702, and a business ID.

  (2: Network name acquisition process and document management area securing process).

  After analyzing the job control language 700, network name acquisition processing is started. FIG. 6 shows a network name creation process executed by the document management server 100 in the network name acquisition process.

The document management server 100 receives a network name acquisition request from the network name acquisition unit 242 (step 111). The network name acquisition request includes, for example, analysis result information. Specifically, for example, if the communication between the job management program 400 and the document management server 100 is an HTTP (HyperText Transfer Protocol) protocol, for example, <DD
NAME = “DATA1”><DSN NAME = “DATAFILE1”><USER NAME = “USDER1” /><DEST NAME = “A” /><PRI NAME = “1” /></DD> A character string surrounded by such tags is generated, and a network name acquisition request including the character string is transmitted.

  When the Web processing unit 160 receives the network name acquisition request using the HTTP protocol, when the character string “<DD” is found, the network name acquisition unit 110 inputs the network name acquisition request, and step 112 is started. The That is, the network name creation unit 110 locks the job identification number 907 (for example, a file) for the purpose of exclusion. This is effective, for example, when a cluster-structured document management server 200 is configured.

  In step 113, the network name creation unit 110 increments the number represented by the locked job identification number 907 by 1 and reads the number after the increment and writes it in the memory 233.

  In step 114, the network name creation unit 110 refers to the current prefix management table 911 using the business ID that is one parameter included in the network name acquisition request as a key, and acquires the current prefix corresponding to the business ID. To do. Then, the network name creation unit 110 combines the acquired current prefix, the number (JOB ID) written in the memory 233, and the file name 702 which is one parameter included in the network name acquisition request. Create a name.

  In step 115, the network name creation unit 110 refers to the document index table 910 and determines whether or not a network name identical to the network name created in step 114 exists. If the same network name exists, step 114 is executed again. Otherwise, the process proceeds to step 116.

  In step 116, the network name creation unit 110 unlocks the job identification number 907.

  As a result, the network name creation unit 110 creates an output such as <URL NAME = "http: // hostA / 489/1 /" /> in the XML format which is the same format as the input. That is, the information is created in the document management area 410 in the network file system 400 excluding the file name from the network name as information for guiding the storage of the file to a location according to the created network name (path name to the file). A path name to the directory (hereinafter referred to as a network directory name) is prepared as an output.

  After the processing flow shown in FIG. 6, the document management area securing unit 120 confirms that the network file system 400 has a free space, so that the directory name composed of the current prefix and the job ID of the network name is changed. A directory (hereinafter referred to as “target directory”) is created. That is, the document management area securing process is executed.

  Also, the document attribute setting unit 130 registers each parameter (business ID, DD name, DD parameter) of the network name acquisition request in the document index table 910. In addition, the document attribute setting unit 130 registers the number written in the memory 233 (the number represented by the incremented job identification number 907) in the document index table 910 as a JOB ID. In addition, the network name creation unit 110 registers the created network name in the document index table 910.

  Further, the document attribute setting unit 130 may store, for example, the input XML file as the property of the target directory in the target directory. For example, if <DSNNAME = “DATAFILE1”> is included in the network name acquisition request, the document attribute setting unit 130 creates a non-display attribute file with a dot such as “.DATAFILE1” and the target It may be stored in a directory. Actually, the application program 234 in the document creation server 200 stores the document file having the file name “DATAFILE1” in the created directory.

  Further, the log creation unit 140 may create and store a log file with the file name “LOG” (hereinafter referred to as “target log file”) in the created target directory. For example, information such as the date and time of creation may be recorded in the target log file.

  The network name returning unit 150 returns the created output (for example, <URL NAME = “http: // hostA / 489/1 /” />) to the document creation server 200. The returned output (network directory path name) is received by the network name acquisition unit 242 in the document creation server 200 and passed to the file creation unit 243.

  (3: File creation process).

  The file creation unit 243 assigns a file having a file name recorded in the job control language 700 to a target directory accessed using the network directory path name (for example, a dummy file having a predetermined size (for example, 0 bytes)) create). This is a check to see if the file can be created. If it is confirmed that the file can be created, the file creation unit 243 locks the file so that it is not updated by another program (for example, a program other than the application program 234). If the size of the document file to be created is known in advance, a document file of that size may be created in advance.

  (4: Application management process).

  In the application management unit 244, an application program 234 is executed. The application program 234 can end the process by overwriting the allocated file (dummy file) in the target directory with the document file created by itself. After the program is completed, the file release unit 245 may determine the file that can print the document by locking the allocated file (dummy file) or matching the previously allocated file size with the document file.

  FIG. 5 shows an example of the flow of application management processing.

  In step 251, the application management unit 244 creates creation file information as child process generation information as information for passing DD parameters to the application program 234. The child process generation information is passed to the application program 234 as an environment variable at the time of child process generation. For example, in the UNIX and PC OSs, when a process for executing a program is generated as a child process, the environment variable of the parent process is passed to the child process in common with multiple platforms. You can take advantage of the ability to take over and execute child processes.

  For example, in FIG. 4, this parent process becomes the operation of the job management program 240, and the child process becomes the operation of the application program 234.

  The created file information using the environment variable is, for example, a network name 906 as a variable value with the DD name 902 as the environment variable name. Specifically, for example, when processing the job control language 700 of FIG. 7, a file name is generated from a character string “http: // hostA / 489/1 / DATAFILE1” and substituted into an environment variable “DATA1”. Environment variable is set in the parent process. This network name 906 is a description that it is a file on host A in the HTTP protocol.

  If the program can access this file name on the platform that executes the job management program 240, the value as it is is substituted into the environment variable. If it cannot be accessed, it is converted to the network file name that matches the platform environment. Even when a plurality of DD parameters are passed to one application program 234, each environment variable is set in the parent process.

  For example, in the specification of the job control language 700, the DD name 902 is an identifier for identifying a file, so that there is no duplicate definition when viewed from the application program 234. Therefore, the process of creating environment variables for the number of DD parameters is the process performed in step 251.

  In step 252, a child process that executes the application program 234 is generated. By this child process generation, the environment variable set in step 251 is handed over to the child process and the environment in which the application program 234 can be executed is prepared.

  In step 253, the application program 234 is actually executed. An application execution process is generated as a child process, and execution is started in a state where environment variables are passed. When referring to or updating a file from the application program 234, the program is described by the DD name of the DD parameter. For example, if the application program 234 is a shell program, for example, if it is a PC server, it is described as “COPY% DATA1% DATA1”, and if it is UNIX, if it is described as “cp $ {DATA1} DATA1”, the platform is called DATA1. The file specified by the DD parameter can be copied to the document.

  In the case of C language, COBOL language, or Java (registered trademark), a DD name can be used from an application as a language library. For example, in the case of C language, when a file is used, the file is opened using a function called fopen (). In the present embodiment, a C language library for job management may be provided, and a function called ddopen () may be provided separately. In fopen (), a file name is input, and information called a file identifier is output even after opening. In the language, the actual file name is recognized only when opened. Therefore, the DD name can be input into the function and converted into an environment variable in the same function as in the shell program so that the file identification name is output in the same way with ddopen ().

  For example, in a language using a job control language used in a large computer, the compiler itself supports the DD name, and the DD of the application source is described. Therefore, the compilers of these large computers are open environments. It is only necessary to add the replacement processing of the environment variable to the DD name processing when porting to the system. This makes it possible to use a file on a network by executing it on a multi-platform server by simply recompiling the source of a large computer.

  In step 254, the job management program 240 waits for the end of the application. After completion, processing can be passed to the file release unit 245 described above.

  (5: Log acquisition process).

  After the file release unit 245 determines the file in the target directory, the log acquisition unit 246 executes the job execution results defined in the input job control language 700 (for example, the application program 234 and the job management program 240). Log (hereinafter referred to as “job execution log” for convenience) is recorded in the target log file in the target directory. The contents of the target log file (information recorded in the target log file and job execution log) are sent from the log acquisition unit 246 to the client terminal 210 or 220 as a response to the input of the job control language 700 from the client terminal 210 or 220. Sent to. The contents of the target log file are displayed on the client terminal 210 or 220. An example of a display screen (hereinafter, log display screen) 1250 is shown in FIG.

  According to the log display screen 1250 of FIG. 9, the contents of the target log file are composed of an index part and a job execution log part. The index part is a part recorded in the stored target log file, although the target log file is stored in the target directory by the document management server 100. The job execution log part is a part recorded by the job management program 240. The job execution log is composed of, for example, first to third log elements. The first log element is the content from the first “document creation server log” to the line one higher than the second “job control language”. Specifically, the application 234 is started and ended. It is a log which shows the event regarding the start and end at the time of having performed. The second log element is the contents from the second “job control language” to the line one higher than the third “document creation server log”. Specifically, the executed job control language 700 This is information about jobs defined in The third log element is the content from the third “document creation server log” to the last line, specifically, information on the file created in the target directory. More specifically, for example, it indicates that document files such as “DATA1”, “DATA2,” “OUT3” are stored in the target directory.

  In this log display screen 1250, the path name indicated by reference number 1251 is displayed in the display area of the index part, and the path name group indicated by reference number 1252 is displayed in the display area of the job execution log part.

  A path name 1251 in the index area display area on the log display screen 1250 is a path name (network directory path name) to the target directory. When this path name is clicked with, for example, a mouse (or even if it cannot be clicked, a URL that is the path name is input to the WEB browser), the target directory window is exemplified as shown in FIG. 161 is displayed. In the target directory window 161, a network directory path name 162 and icons 163 of a plurality of files existing in the target directory are displayed. In other words, the icon of the document file or target log file corresponding to the job is displayed. That is, a plurality of files related to the job are collectively managed in the target directory. The user can browse the contents of the file by designating the icon of the desired file.

  The path name group 1252 in the display area of the job execution log part on the log display screen 1250 is a plurality of network names respectively corresponding to a plurality of files existing in the target directory. For example, when a predetermined position in the display range of the path name group 1252 is designated with a mouse or the like, the print instruction screen 164 illustrated in FIG. 12 is displayed.

  The print instruction screen 164 is a screen displayed on a WEB browser, for example. The print instruction screen 164 displays a first display area “job information” and a second display area “output file information”.

  The first display area “job information” includes a job ID display field 165. Since the print instruction screen 164 illustrated in FIG. 12 is displayed via the display screen (see FIG. 9) of the target log file corresponding to the job ID “1”, the job ID display field 165 includes “1”. Is displayed.

  In the second display area “output file information”, a file name display area 166 of a document file that can be selected as a print target, a print button 167, and a cancel button 168 are displayed. In the display area 166, a check box is displayed for each selectable document file. Further, for each selectable document file, the distribution destination identifier and importance are displayed (since these information are included in the second log element in the contents of the target log file described above, It may be displayed using the second log element or may be displayed using the document index table 910). When the user puts a check mark in a check box corresponding to one or more desired document files using a mouse or the like and presses the print button 167, the desired one or more document files are distributed correspondingly. It can be output (printed) from the beginning. If the cancel button 168 is pressed, the print instruction screen 164 can be closed. Further, for example, if the file to be printed has already been decided on the log display screen 1250 of FIG. 9, by specifying the network name corresponding to the desired file (for example, “DATA1”) in the path name group 1252, As illustrated in FIG. 12, the document file corresponding to “DATA1” can be displayed in a selected state.

  Hereinafter, an example of the flow of processing relating to printing will be described with reference to FIG.

  When one of the network names in the path name group 1252 on the log display screen 1250 (see FIG. 9) is clicked with the mouse, the WEB processing unit 160 in the document management server 100 receives the clicked network name, In response, information for displaying the print instruction screen 164 is prepared and transmitted to the client terminal 210 or 220 (step 181). When preparing the information on the print instruction screen 164, the job ID in the clicked network name is embedded in the display field 165, and the DD name, distribution destination, and importance level that can be acquired from the document index table 910 using the job ID as a key. Is displayed in the display area 166 with a check box.

  The web processing unit 160 receives and analyzes the result of the operation on the print instruction screen 164 on the client terminal 210 (step 182). For example, if the web processing unit 160 determines that reception has failed or the cancel button 168 has been clicked, the web processing unit 160 terminates the processing, and determines that one or more document files to be printed have been selected and the print button 167 has been clicked. In this case, a print instruction is input to the print instruction receiving unit 170 together with the DD name of the washed document file. Thereby, step 183 is started.

  In step 183, the print instruction receiving unit 170 acquires a distribution destination 904 (for example, “A”) corresponding to the input DD name (for example, “DATA1”) from the document index table 910.

  In step 184, the print instruction receiving unit 170 determines the configuration status corresponding to the acquired distribution destination (for example, “A”) (that is, the output destination 500 is configured by which output server 500 and which output device 510, and the printing paper. Is output from the output destination management table 940 (see FIG. 8). According to the example of FIG. 8, there are two configuration situations corresponding to the distribution destination “A” in the output management table 940. As described above, when there are two or more configuration states, the print instruction receiving unit 170 executes the load distribution unit 930, and the load distribution unit 930 averages the number of pages 944 for the two or more configuration states. Thus, the configuration status is selected (that is, the combination of the output server 500 and the output device 510 is selected).

  In step 185, the print transmitting unit 180 sends a print instruction for printing the selected document file to be printed (for example, a print instruction including the document file itself or a path name to the document file). It transmits to the output server 500 corresponding to the selected configuration status. In the print instruction, for example, the output server 942 and the output device 943 recorded in the output management table 940 corresponding to the selected configuration status are specified. The output server 500 that is the transmission destination of the print instruction establishes a session of the port corresponding to the designated output device 943 with the output device 500 corresponding to the output device 943, and prints the document file to be printed. Output data.

  The print instruction transmitted from the document management server 100 to the output server 500 further includes various information elements (for example, various information elements that can be acquired from the document index table 910) corresponding to the document file to be printed. It may be. The output server 500 may include various information elements (for example, at least one of JOB ID and business ID) in the print data transmitted to the output device 510. The output device 510 may print the information element together with the contents of the document file. As a result, the person who sees the print result of the document file can grasp which job or which job the document corresponds to.

  As mentioned above, although embodiment of this invention was described, this embodiment is only the illustration for description of this invention, and is not the meaning which limits the scope of the present invention only to that embodiment. The present invention can be implemented in various other modes without departing from the gist thereof.

  For example, the computer programs 110, 120, 130, 140, and 150 described above may be executed by the document creation server 200 or 300.

  Further, for example, each directory (business directory) corresponding to each business is created in the network file system 400, and a plurality of directories (job directories) respectively corresponding to a plurality of jobs corresponding to the business are created in the business directory. ) And a document corresponding to the job may be stored in the job directory. That is, from the directory tree represented by the network file system 400, the business flow, the correspondence between the business and the job, and the correspondence between the job and the document may be known. In other words, management (business, job, and document management) using the characteristics of the directory tree structure in the file system 400 may be executed.

  Further, for example, the display of the desired directory window and the display of the print instruction screen are performed through the display of the job schedule window 951 illustrated in FIG. 14 in addition to the display of the log display screen of the target log file. It may be done. For example, the client terminal 210 or 220 requests the document management server 100 to display the job schedule, and the WEB processing unit 160 of the document management server 100 transmits the information of the job schedule window 951 to the client terminal 210 or 220, for example. . The information can be created based on, for example, a document index table 910 or a business management table (not shown) (for example, a table in which a plurality of business IDs and business flows respectively corresponding to a plurality of business are defined). . In the job schedule window 951, for example, a business flow and icons corresponding to each business that is an element of the flow are displayed. For example, when the icon 952 corresponding to the business ID “489” is clicked on the job schedule window 951, the WEB processing unit 160 receives the information of the business ID “489” from the client terminal 210 or 220. The WEB processing unit 160 acquires all job IDs corresponding to the business ID “489” from the document index table 910 and transmits the acquired job IDs (for example, “1” and “2”) to the client terminal 210 or 220. As a result, as shown in FIG. 14, a list of job IDs corresponding to the job ID “489” is displayed near the icon 952 of the job ID “489”. When a job ID corresponding to the job ID list is selected, a directory window as shown in FIG. 11 (a directory window corresponding to the selected job ID) and a print instruction screen as shown in FIG. A screen displaying one or more document files corresponding to the job ID in a selectable manner) or a log display screen as shown in FIG. 9 (displaying the contents of the log file existing in the directory corresponding to the selected job ID) Screen) may be displayed.
