Description

  The present invention relates to an application execution system that executes an application via a communication network such as a LAN or the Internet, a computer, an application execution method of the application execution system, and a program.

Conventionally, in this type of application execution system, an application is executed on the application server side based on an application execution request from a client terminal. This application execution system includes an application server having an application and a client terminal connected to the application server via the Internet, and the application server includes a database used when executing the application (Patent Document 1). reference).
JP 2003-186380 A

  By the way, in recent years, the application execution system as described above has been constructed by various vendors, and the user selects and uses a service necessary for the user. However, the application execution system as described above has a problem that communication is interrupted and a sufficient response speed cannot be obtained when the Internet line is unstable. Furthermore, when the server is down or the line is disconnected, there is a problem that the user cannot receive the service until the system is restored. In this case, a proxy server that executes an application instead of the above application server is installed for each application (for each vendor) in the user's LAN, and each application server is synchronized with the corresponding proxy server. It can be considered to take. In this way, the client terminal can acquire the execution result of the application by accessing the proxy server connected via the LAN without going through the Internet.

  However, when a plurality of proxy servers are connected to the LAN, maintenance and operation costs increase, and a larger installation space for the proxy servers must be secured. Therefore, in order to solve such a problem, a method of introducing an application provided by a plurality of vendors to one proxy server and a database corresponding to these applications can be considered. However, this method does not have an execution environment that supports all of the applications and databases provided by multiple vendors on the proxy server, so if multiple applications and databases coexist and execute each other, There is a risk of malfunction. For example, when a memory leak occurs in one application, the memory area is shared with a plurality of other applications. Therefore, there is a problem in that the other applications are also affected and do not operate. Further, since a single server usually has only one database engine, it is difficult to operate different types of databases.

  Accordingly, it is an object of the present invention to provide an application execution system, a computer, an application execution method for the application execution system, and a program capable of executing a plurality of applications without affecting each other and without causing problems with each other. It is said.

  The application execution system of the present invention includes one or more application providing servers that provide an application execution set in which an application and at least one or more database used when executing the application are set, and application execution acquired from the application providing server. The application execution device that executes the set is connected by the first network, and the application execution device and the client terminal that requests the application execution device to execute the application execution set are connected by the second network. An application execution system for acquiring an execution set from an application providing server. And an execution set storage means for storing a plurality of acquired application execution sets, a container constructed for each application execution set and serving as an application operating environment, and at least one database is accessed based on the operation of the application A plurality of application execution environments, and execution set execution means for executing an application execution set stored in the application storage unit in each application execution environment, and the client terminal is connected to the application execution device. An execution request unit that requests execution of any one of the application execution sets stored in the execution set storage unit is provided.

  The application execution method of the application execution system according to the present invention includes one or more application providing servers that provide an application execution set in which an application and at least one database used when executing the application are set, and each application execution set And an application execution apparatus having a plurality of application execution environments, each of which includes a container that is constructed in the above and serves as an operation environment of the application, and a database engine that accesses at least one database based on the operation of the application. Of the application execution system in which the application execution device and the client terminal are connected by the second network. In the application execution method, the application execution device stores an application execution set from the application providing server, stores a plurality of acquired application execution sets, and executes each application execution environment based on an execution request from the client terminal. And a step of executing the application execution set.

According to these configurations, for example, the client terminal can acquire the execution result of the application by accessing the application execution device connected via the LAN without going through the Internet. As a result, the application can be executed in a stable environment without being influenced by the Internet line.
In addition, even if multiple applications developed by different vendors are executed in parallel while coexisting on a single application execution device, an application execution environment is prepared for each application, so there is a problem with each other. The execution result can be output to the client terminal without any influence. For example, even when a memory leak occurs in one application, the memory area is divided for each application execution environment, so other applications are affected and the operation does not stop. In addition, since a database engine for accessing the database of each application is provided for each application execution environment, different types of databases can be used in a single application execution apparatus.
Furthermore, since the application providing server provides the application execution device with the application and the database as a set, the acquisition operation of the application execution device can be simplified.

  In this case, the application execution device further includes a cooperation application describing a cooperation relationship between a plurality of application execution sets, and executes the cooperation application in the application execution environment in accordance with an execution request of the client terminal, and links the plurality of application execution sets. It is preferable to execute it.

  According to this configuration, a plurality of applications can be linked and used widely, and the linked applications do not cause problems with each other. For example, a business trip management application and a timetable application can be linked to present information related to travel expenses and transportation used for business trips. The cooperative application may be arranged in a dedicated application execution environment, or may be arranged in an application execution environment of another application.

  In this case, when the execution set acquisition unit acquires the application execution set from the application providing server, the application execution device determines whether or not there is an application execution environment for executing the application execution set, and the result When it is determined that the application execution environment does not exist, it is preferable to further include notification means for notifying that effect.

  According to this configuration, when a plurality of application execution environments constructed in the application execution device are all used for another application execution set, it is notified that no usable application execution environment remains. Thus, it is possible to take early measures such as replacing the application execution set and adding an application execution environment.

  The computer of the present invention preferably functions as an application execution device used in the above application execution system.

  A program according to the present invention causes a computer to execute each step in the application execution method of the application execution device.

  By using these, it is possible to provide a computer and a program capable of executing a plurality of applications without causing problems with each other without being influenced by the Internet line.

  Hereinafter, an application execution system, a computer, an application execution method of the application execution system, and a program according to embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a system configuration diagram of an application execution system 1 according to an embodiment of the present invention. The application execution system 1 of the present invention includes a plurality of vendors (X company, Y company, Z) that provide an application execution set 9 in which the application 7 and at least one database 8 used when the application 7 is executed. Offices (offices A1, A2, A3, B1, B2, etc.) of a plurality of users (Company A, Company B) using the application execution servers 9a, 2b, 2c and the application execution set 9. Each application execution device 3aa, 3ab, 3ac, 3ba, 3bb, 3bc installed in B3) is connected to the Internet 5 (first network), and each application execution device 3 and the application execution device 3 Two client terminals 4 requesting the execution of the application 7 There are connected by an office LAN 6 (second network).

  The application providing server 2 provides an application execution set 9 in response to a request from the application execution device 3. Here, the application execution set 9 includes update data for the application 7 and the database 8 in addition to the application 7 and the database 8. Each application 7 and each database 8 are created in different development environments depending on vendors.

  The application execution device 3 is installed at each office of the user and executes the application execution set 9 downloaded from the application providing server 2 in response to an execution request from the client terminal 4 at each office. That is, the application execution device 3 functions as a server of server-based computing (SBC) such as a housing service or a hosting service in the office. Accordingly, each client terminal 4 is configured to be able to acquire the execution result of the application 7 without installing the application 7.

  Next, the control configuration of each device (the application providing server 2, the application execution device 3, and the client terminal 4) constituting the application execution system 1 of the present invention will be described with reference to FIG. Since the hardware configuration of the application providing server 2 and the client terminal 4 is the same, the description will be given by taking the application providing server 2 as an example.

  The application providing server 2 is similar to a so-called general computer, and includes an input device 11, a display 12, a communication interface 13, an input / output interface 14, an internal bus 15, a CPU 16 (Central Processing Unit), a ROM 17 (Read Only Memory), A RAM 18 (Random Access Memory) and an HDD 19 (Hard Disk Drive) are provided. The HDD 19 stores an operating system (not shown) and an application execution set 9 to be provided to the application execution device 3. The client terminal 4 is not limited to a personal computer, and may be various printing apparatuses such as a receipt issuing apparatus or a portable information terminal.

  The application execution device 3 is different from the above devices (the application providing server 2 and the client terminal 4) in that the input device 11 and the display 12 are not provided, but the other control configurations are the same. In addition, the HDD 29 of the application execution apparatus 3 stores a plurality of application execution environments 41 configured to execute the application execution set 9. Each application execution environment 41 includes a container 42 serving as an operating environment for operating the application 7 and a database engine 43 for accessing the database 8 when the application 7 is used (see FIG. 3). Further, resources such as a memory area of the RAM 28 are allocated to each application execution environment 41. For example, even when a memory leak occurs, the application execution set 9 arranged in another application execution environment 41 is affected and the operation is performed. Never stop.

  Here, the functional configuration of the application execution system 1 will be described with reference to FIG.

  The application execution device 3 includes an execution set acquisition unit 51, an execution set storage unit 52, an execution set execution unit 53, and a notification unit 54.

  The execution set acquisition unit 51 designates the URL of the application providing server 2 and downloads the application execution set 9 from the application providing server 2. The execution set storage unit 52 stores the application execution set 9 acquired by the execution set acquisition unit 51 in the HDD 29 in association with the application execution environment 41. In other words, the application execution device 3 stores the application execution set 9 acquired for each application execution environment 41 in a state where the application 7 is set in the container 42 and the database 8 is set in the database engine 43. (See FIG. 3).

  The execution set execution unit 53 executes the application execution set 9 in the application execution environment 41 in response to an execution request from the client terminal 4. When the application execution set 9 is executed, the program in the application 7 is read, and the execution result is output by referring to the database 8 based on the description content of the program. When storing the downloaded application execution set 9 in the HDD 29, the notifying unit 54 informs the client terminal 4 of the fact that the application execution environment 41 for making correspondence does not remain in the other application execution sets 9 and remains. This is displayed on the display 32. Thereby, measures such as replacement of the application execution set 9 and addition of the application execution environment 41 can be taken at an early stage. The notification unit 54 may be provided with a lamp or a speaker in the application execution apparatus 3 so as to be visually displayed by lamp display, or may be configured to notify by sound (electronic sound) of the speaker.

  Note that the execution set storage unit 52 includes, for example, an HDD 29. The execution set acquisition unit 51 and the execution set execution unit 53 calculate various data according to a control program in the ROM 27 and various programs in the HDD 29. Further, it is realized by executing processing in cooperation with the communication interface 23. In addition, in the notification unit 54, the CPU 26 calculates various data according to the control program in the ROM 27 and the various programs in the HDD 29, and further executes the process in cooperation with the communication interface 23, the display 32 of the client terminal 4, and the communication interface 33. It is realized by doing.

  The client terminal 4 includes execution request means 55. The execution request unit 55 requests the application execution device 3 to execute the application 7. The execution request means 55 is realized when the CPU 36 calculates various data according to the control program in the ROM 37 and various programs in the HDD 39 and further executes the processing in cooperation with the input device 31 and the communication interface 33. Is.

  Next, the flow of the acquisition process and the execution process of the application execution set 9 in the application execution device 3 will be described with reference to the flowchart of FIG. First, based on the download request from the client terminal 4, the application execution device 3 accesses the URL of the application providing server 2 that stores the desired application execution set 9 (S01). Then, the application execution device 3 downloads the application execution set 9 from the application providing server 2 (S02). At this time, if the application execution environment 41 for placing the downloaded application execution set 9 does not remain in the application execution device 3 (S03: No), this is displayed on the display 32 of the client terminal 4 (S04). ). On the other hand, if the application execution environment 41 remains (S03: Yes), the application execution environment 41 is stored in its own HDD 29 in correspondence with the application execution environment 41 (S05).

  When the client terminal 4 makes an execution request for the application 7 to the application execution device 3 (S06), the application execution device 3 receives the execution request (S07), and the application execution set 9 to be executed is arranged. The application execution set 9 is executed in the application execution environment 41 (S08). Then, the application execution device 3 transmits the execution result to the client terminal 4 (S09).

  At this time, the application execution device 3 may be configured to execute the cooperative application. This cooperative application is for executing an application 7 and another application 7 in cooperation with each other, and is described in the WSDL format. Each application 7 is accessed with reference to the cooperation information described in the cooperation application. The linkage information is information such as a command sentence defined in each application 7. By executing this cooperative application, a plurality of applications 7 can be linked and widely used, and the linked applications 7 do not cause problems with each other. For example, it is possible to link the business trip management application 7 and the timetable application 7 to present information related to the travel expenses and business facilities used for the business trip. The cooperative application may be arranged in the dedicated application execution environment 41 or may be arranged in the application execution environment 41 of another application 7.

  In addition, it is good also as a structure which prescribes | regulates whether the application 7 is executable for every user and the client terminal 4. FIG. When the execution of the application 7 is restricted for each user, information that associates the user ID with “executable” and “unexecutable” of the application 7 is stored in the application execution device 3, and based on this information The users who can use the application 7 are restricted. As a result, unauthorized access by the user can be prevented, and a dedicated application execution environment 41 can be allocated in the application execution device 3 for each user.

  Further, when the execution of the application 7 is restricted for each client terminal 4, information that associates the identification ID of the client terminal 4 with “executable” and “executable” of the application 7 is stored. The client terminals 4 that can use the application 7 are restricted based on the information. Accordingly, unauthorized access by the client terminal 4 can be prevented, and each client terminal 4 can be specialized for a specific function, and a dedicated application execution environment 41 can be allocated in the application execution device 3 for each client terminal 4. An IP address or a MAC address may be used instead of the identification ID.

  The application execution system 1 may be configured to include a management server that functions as a reception window for the application providing server 2 (vendor) to provide the application execution device 3 (user) to the application execution set 9. In this case, the application execution device 3 (user) acquires information about each application execution set 9 provided by a plurality of vendors from the management server, and based on this information, the application execution set 9 is acquired from the application providing server 2. to download. With this configuration, the user can acquire information on the application execution set 9 via the management server without individually accessing the plurality of application execution devices 3, and can easily search the application execution set 9. Can do.

According to the above configuration, the client terminal 4 can obtain the execution result of the application 7 by accessing the application execution device 3 connected via the intra-office LAN 6 without going through the Internet 5. Thereby, the application 7 can be executed in a stable environment without being influenced by the Internet line.
Further, even if a plurality of applications 7 developed by a plurality of different vendors are executed in parallel in a state where they coexist in a single application execution device 3, an application execution environment 41 is prepared for each application 7. The execution result can be output to the client terminal 4 without causing any problems. For example, even when a memory leak occurs in one application 7, the memory area is divided for each application execution environment 41, so that other applications 7 are affected and the operation does not stop. In addition, since the database engine 43 for accessing the database 8 of each application 7 is provided for each application execution environment 41, different types of databases 8 can be used by the single application execution device 3.
Furthermore, since the application providing server 2 provides the application 7 and the database 8 as a set to the application execution device 3, the acquisition operation of the application execution device 3 can be simplified.

  On the other hand, each function of the application execution system 1 shown in the above example can be provided as a software program. Further, the program can be provided by being stored in a recording medium (not shown). As the recording medium, a CD-ROM, flash ROM, memory card (compact flash (registered trademark), smart media, memory stick, etc.), magneto-optical disk, digital versatile disk, flexible disk, and the like can be used.

  Regardless of the embodiment described above, the processing steps of the application execution system 1 can be changed as appropriate without departing from the scope of the present invention.
