Description

  The present invention relates to an information communication program, an information communication apparatus, and an information communication method for making a search request to a plurality of servers that store and manage transaction information in a financial institution distributed for each store.

  Financial institutions that operate throughout the country, such as city banks, have a large number of customers. Instead of centrally managing all transaction information on a single server, the country is divided into multiple blocks. In addition, transaction information is distributed and stored in block units. When a customer conducts a transaction at a sales store under the server where his / her transaction information is managed, the operator may refer to the transaction information in the server by making a search request from the terminal of the business store. it can.

  In addition, information on customers who are going to do business may be managed by servers of other sales offices. In such a case, the terminal of the sales store that has received the request makes a search request to the servers in all other sales offices. At that time, there is no problem if the response to the request is immediately returned from the server at all other sales offices. However, if some servers cannot be connected, May take time to know that they can't communicate. The terminal tries to reconnect to a server that cannot communicate (for example, see Patent Document 1), but the reconnection interval and number of times are determined in advance, and the number of times of reconnection reaches a predetermined number This is because it is determined that communication cannot be performed for the first time.

  Possible causes for the server being unable to connect are that the server is down or an abnormality has occurred in the communication line. The server has a working machine and a standby machine, and has a cluster configuration so that when the active machine goes down, the standby machine is started and business can be continued. In particular, when the standby machine is started from the cold standby state, it takes a considerable time until the server is restored after the cluster is switched, and the server stop time becomes long. Also, when an abnormality occurs in a communication line, it often takes time until the line is restored, and as a result, the time during which the connection with the server cannot be made may become long.

JP-A-6-89239

  In the conventional technology, when the terminal and the server are not connected, it is determined that the terminal cannot connect when the reconnection attempt is not successful, and the operator of the terminal is kept waiting during that time. There was a problem that was interrupted.

  The present invention has been made in view of the above points, and an information communication program and an information communication apparatus for preventing an operator from waiting even if there is a server that cannot be connected among a plurality of servers. And an information communication method.

  In the present invention, in order to solve the above-mentioned problem, the computer periodically checks and stores the connection status with all servers, and stores the status after trying to reconnect to an unconnected server. When the connection status is updated and when a search for transaction information is accepted, a search is made to the connected server with reference to the connection status, and there is transaction information corresponding to the response from the connected server When the relevant transaction information is displayed and there is no relevant transaction information and there is no unconnected server, information without relevant data is displayed, or there is no relevant transaction information and an unconnected server In some cases, an information communication program is provided that displays information indicating that the connection process is in progress and causes the process to be executed.

  Further, in the present invention, in an information communication device that requests a search to a plurality of servers that store and manage transaction information in a distributed manner for each store, the connection status with all servers is periodically checked. A server connection state monitoring unit, a server connection state storage unit for storing a monitoring result by the server connection state monitoring unit, and a reconnection processing unit for trying to reconnect an unconnected server with reference to the server connection state storage unit A search acceptance processing unit that accepts a search for the transaction information, and when the search acceptance processing unit accepts a search for the transaction information, the server connection state storage unit is referred to search for a connected server. If there is corresponding transaction information for the response from the connected server, the transaction information is displayed, there is no corresponding transaction information, and there is no unconnected server A search request processing unit that displays information without corresponding data or displays a message indicating that connection processing is in progress when there is no corresponding transaction information and there is an unconnected server. A featured information communication device is provided.

  Furthermore, in the present invention, the computer checks the connection status with all servers, and repeatedly tries to reconnect to a server that is not connected to update the connection status periodically. When a search is received, a request is made to the connected server with reference to the connection state, and when there is transaction information corresponding to a response from the connected server, the transaction information is displayed. When there is no corresponding transaction information and there is no unconnected server, information without corresponding data is displayed, or when there is no corresponding transaction information and there is an unconnected server, this means that connection processing is in progress. An information communication method characterized by displaying a message is provided.

  Since the information communication program, information communication apparatus, and information communication method configured as described above notify the connection processing in progress when there is no corresponding transaction information in the server response to the search request and there is an unconnected server, There is an advantage that the search result in can be immediately known. Since no attempt is made to reconnect to an unconnected server at the time of executing a search request, the operator can immediately check the current search result without waiting for a long time.

  Hereinafter, with respect to the embodiment of the present invention, a search request may be made to all servers in an information communication system having a plurality of sales offices and a server installed for each sales office like a city bank. A case where the present invention is applied to a terminal that can be used will be described in detail with reference to the drawings. Each embodiment can be implemented by combining a plurality of embodiments within a consistent range.

FIG. 1 is a diagram showing a configuration example of an information communication system including the information communication apparatus according to the first embodiment, and FIG. 2 is a flowchart showing a flow of information communication control processing.
The information communication system includes a plurality of servers 10, 20, 30 installed for each sales office, and the servers 10, 20, 30 are connected to each other via a network 40 so as to communicate with each other. Yes. Servers 10, 20, and 30 are connected to databases 12, 22, and 32, respectively. In the databases 12, 22, and 32, transaction information for each block is stored and managed. In addition, each sales office, for example, a sales office having the server 10 and a sales shop under its control, have a plurality of terminals 50 and are connected to the server 10 by a LAN (Local Area Network) 42 or the like. Has been. Although not shown, a plurality of terminals are connected to the other servers 20 and 30 in the same manner.

  The terminal 50 functions as an information communication device, and includes a search reception processing unit 51, a search request processing unit 52, a server connection state monitoring unit 53, a server connection state storage unit 54, and a reconnection processing unit 55. The search reception processing unit 51 performs a search reception process in response to an input of a search condition when an operator inputs a transaction information inquiry. The search request processing unit 52 requests the servers 10, 20, and 30 to search based on the operation input received by the search reception processing unit 51, and acquires the search results from the servers 10, 20, and 30. The server connection state monitoring unit 53 monitors the connection state with the servers 10, 20, and 30 by life and death confirmation that is periodically performed. The server connection state storage unit 54 stores the monitoring result from the server connection state monitoring unit 53. As a result of monitoring by the server connection state monitoring unit 53, the reconnection processing unit 55 tries to reconnect to an unconnected server when the connection state with the servers 10, 20, and 30 is not connected. The reconnection processing unit 55 attempts to connect to all the servers when the terminal 50 is activated. Therefore, the operation of the terminal 50 described below is based on the assumption that there is a connection record with the server.

  In the terminal 50 having the above configuration, the server connection state monitoring unit 53 regularly monitors the connection state with all the servers 10, 20, and 30, and stores the monitoring result in the server connection state storage unit 54. ing. In addition, the reconnection processing unit 55 refers to the server connection state storage unit 54, and if there is a server whose connection state is not connected, the reconnection processing unit 55 performs reconnection to the server. Thereby, the terminal 50 always keeps track of the connection status with all the servers 10, 20, and 30 immediately after the startup, and the server or the communication line that has become unconnected due to a failure or the like, Reconnection is repeated until it is connected.

  Here, the processing operation when the terminal 50 receives a search for transaction information will be described with reference to FIG. Note that the server connection state monitoring unit 53, the server connection state storage unit 54, and the reconnection processing unit 55 have been operating since the start of the terminal 50, and the server connection state is always updated to the latest state. .

  First, the terminal 50 waits for a transaction information search (step S1). When the search reception processing unit 51 receives a search condition and receives a search for transaction information, the search request processing unit 52 refers to the server connection state storage unit 54 and refers to the sales office to which the business store with the terminal 50 belongs. It is confirmed whether or not the connection state of the server 10 is being connected (step S2). The search request processing unit 52 determines whether or not the server 10 is connected (step S3). If the server 10 is connected, the search request processing unit 52 transmits a search request together with the search condition to the server 10, and the server 10 10 waits for a response of the search result (step S4).

  Upon receiving the search request, the server 10 searches the database 12 using the search condition notified from the terminal 50 as a key, and if there is transaction information corresponding to the search condition, acquires the transaction information and transmits it to the terminal 50. .

  In the terminal 50, the search request processing unit 52 determines whether or not there is corresponding transaction information in the response from the server 10 (step S5). If there is transaction information, the search request processing unit 52 displays the transaction information on a monitor (not shown) (step S6).

  Next, when there is no transaction information corresponding to the server 10 or when the server 10 is not connected, the connection of the other servers 20 and 30 except for the server 10 stored in the server connection state storage unit 54 The state is confirmed (step S7). The search request processing unit 52 determines whether there is a connected server among the other servers 20 and 30 (step S8), and transmits the search request together with the search conditions to the connected servers. The server waits for a search result response from the server (step S9).

  The server that has received the search request searches the database using the search condition notified from the terminal 50 as a key, and if there is transaction information corresponding to the search condition, acquires the transaction information and transmits it to the terminal 50.

  In the terminal 50, the search request processing unit 52 determines whether or not there is corresponding transaction information in the response from the server (step S10). If transaction information corresponding to the search condition is found in the server that has received the search request, the transaction information is acquired and displayed on a monitor (not shown) (step S6).

  If there is no connected server in the server connection state storage unit 54 or there is no transaction information corresponding to the search condition in the connected server, transaction information corresponding to the search condition exists in the unconnected server. there's a possibility that. In such a case, a list of servers in connection processing that have been set as unconnected in the server connection state storage unit 54 is displayed on a monitor (not shown) (step S11).

  As described above, the terminal 50 always stores the latest connection state of the server from the time of activation, can immediately recognize an unconnected server that cannot communicate when requesting a search, and is not connected. The server is not requested to search. For this reason, even if there is no transaction information that matches the search conditions on the connected server, and there is an unconnected server, the result is immediately displayed on the monitor, so the operator must wait. It is possible to check the search result immediately.

  When a list of servers that are not connected and are being connected is displayed, the operator may request a re-search after a while. In this case, it is preferable that the terminal 50 holds a server that has not been connected, and the re-search can be requested only to the unconnected server. Alternatively, the search request processing unit 52 monitors the state transition from the unconnected state to the connected state in the server connection state storage unit 54, and sequentially requests the servers having the state transition at the timing of the state transition. May be performed. Here, if transaction information that matches the search conditions is found, or if transaction information that matches the search conditions is not found on all servers, a message to that effect is displayed if there is a job currently being processed. Wait until it finishes and display it on the monitor.

FIG. 3 is a diagram illustrating a configuration example of a computer used in the first embodiment.
The computer 100 is entirely controlled by a CPU (Central Processing Unit) 101. A RAM (Random Access Memory) 102 and a plurality of peripheral devices are connected to the CPU 101 via a bus 108.

  The RAM 102 is used as a main storage device of the computer 100. The RAM 102 temporarily stores at least part of an OS (Operating System) program and application programs to be executed by the CPU 101. The RAM 102 stores various data necessary for processing by the CPU 101.

  Peripheral devices connected to the bus 108 include an HDD (Hard Disk Drive) 103, a graphic processing device 104, an input interface 105, an optical drive device 106, and a communication interface 107. The peripheral device connected to the bus 108 may be equipped with an input / output interface such as a USB (Universal Serial Bus), although not shown.

  The HDD 103 magnetically writes and reads data to and from the built-in disk. The HDD 103 is used as a secondary storage device of the computer 100. The HDD 103 stores an OS program, application programs, various data, and an application program for information communication control processing shown in FIG. As the secondary storage device, a semiconductor storage device such as an SSD (Solid State Drive) can also be used. In addition to the built-in secondary storage device, the HDD 103 can also be used as an external secondary storage device for storing database data.

  A monitor 109 is connected to the graphic processing device 104. The graphic processing device 104 displays an image on the screen of the monitor 109 in accordance with a command from the CPU 101. Examples of the monitor 109 include a liquid crystal display device.

  A keyboard 110 and a mouse 111 are connected to the input interface 105. The input interface 105 transmits signals sent from the keyboard 110 and the mouse 111 to the CPU 101. Note that the mouse 111 is an example of a pointing device, and other pointing devices can also be used. Examples of other pointing devices include a touch panel, a tablet, a touch pad, and a trackball.

  The optical drive device 106 reads an OS program, an application program, or data recorded on the optical disc 112 using a laser beam or the like. The optical disc 112 is a portable recording medium on which data is recorded so as to be readable by reflection of light, and includes a DVD (Digital Versatile Disc), a CD-ROM (Compact Disc Read Only Memory), and the like.

  The communication interface 107 is connected to the network 40. The communication interface 107 transmits / receives data to / from other computers or communication devices via the network 40.

  With the hardware configuration described above, the processing functions of the terminal 50 according to the first embodiment can be realized. Note that the servers 10, 20, and 30 shown in FIG. 1 can also be realized by the same hardware as in FIG.

FIG. 4 is a diagram showing a relationship between a terminal and a server according to the second embodiment, and FIG. 5 is a diagram showing an example of slip image data.
The terminal 50 includes a terminal control program 56 and a communication program 57, and constitutes an information communication program. The terminal control program 56 is a user program that functions to perform processing for operator input and to display processing results. On the other hand, the communication program 57 has a server connection state monitoring function and a server communication control function. The server connection status monitoring function periodically checks the connection status with the server, and if there is an unconnected server, it can reconnect to that server and perform a search request at any time. I am doing so. The communication control function communicates with all servers connected to the terminal 50 in response to a request from the terminal control program 56 and requests a search process. If there is a response from the server, the response is sent to the terminal control program 56. I am trying to return it.

  The server connected to the terminal 50 can be a server that manages the slip databases 13, 23, and 33 in the illustrated example. For example, the server of the slip database 13 can be the server 10 in FIG. 1, and the servers of the slip databases 23 and 33 can be the servers 20 and 30 of other stores. The slip databases 13, 23, and 33 store data tables 14, 24, and 34, which are correspondence tables of slip numbers and slip image data, respectively, and the entity of the slip image data. In the second embodiment, the slip number of each server is a unique number in the information communication system.

  In the terminal 50, for example, when a slip number is input from the keyboard 110, the terminal control program 56 requests the communication program 57 to perform a search process, and the communication program 57 performs the search process for the slip number all at once. Ask. All the servers search the slip databases 13, 23, 33 using the notified slip number as a search condition as a key, and if there is a corresponding slip number, sends the corresponding slip image data to the terminal 50. If there is no corresponding slip number, for example, message data “No corresponding data” is transmitted to the terminal 50.

  When the terminal 50 receives a response from the server, the communication program 57 passes the received slip image data to the terminal control program 56, and the terminal control program 56 displays the slip image data on the monitor 109. If there is no slip image data in the response from the server, a message of “no corresponding data” is displayed on the monitor 109. For example, as shown in FIG. 5, the slip image data is obtained by converting the transaction information entered and signed and signed into the slip into image data.

  FIG. 6 is a flowchart showing the flow of processing of the terminal control program. Note that the terminal 50 according to the second embodiment is also configured with the same hardware as the hardware illustrated in FIG. 3, and therefore the following processing is performed by the CPU 101.

  In the terminal control program 56, first, the CPU 101 determines whether or not there is an input such as a slip number from the operator, and waits until there is an input (step S21). When a slip number or the like is input, the CPU 101 requests the communication program 57 to perform a search process using the slip number as a search condition (step S22).

  Next, the CPU 101 determines whether or not there is a response. If there is no response, the CPU 101 waits until there is a response (step S23). If there is a response, the CPU 101 determines whether the response includes slip image data that is received data from the server (step S24). If slip image data is included in the response, the CPU 101 displays the slip image data on the monitor 109 (step S25).

  If there is a response with no received data, the CPU 101 determines whether there is a notification of an unconnected server from the communication program 57 (step S26). If there is no unconnected server, for example, a message “No corresponding data” is displayed on the monitor 109. (Step S27). If there is a notification of an unconnected server, the CPU 101 displays, for example, a list of servers being connected on the monitor 109 (step S28). When the screen display is finished in steps S25, S27, and S28, the process returns to step S21.

  As described above, in this communication program, if there is search data in the server that responds after requesting the communication program 57 for search processing, the data is preferentially displayed on the screen. If there is no search data among the servers that can be searched and there is no notification of an unconnected server, the screen displays that there is no corresponding data. If there is an unconnected server, a list of unconnected servers notified immediately is displayed without waiting for a reconnection attempt to the server. Thereby, the operator can know the search result without waiting.

  FIG. 7 is a flowchart showing the processing flow of the communication program, FIG. 8 is a diagram showing a table used for the communication processing, (A) is a server management table, (B) and (C) are work tables. Yes. FIG. 9 is a flowchart showing the flow of the server connection state update process.

  First, the communication program 57 makes the state of the server management table unconnected at the time of activation (step S31). As shown in FIG. 8A, the server management table has columns of “server name”, “host name”, “IP address”, and “status”. When the communication program 57 is activated, the CPU 101 Initialize the “Status” column to “Not connected”. Next, the CPU 101 sets a variable n representing the connection processing in progress number to “0” (step S32). Next, the CPU 101 executes server connection state update processing (step S33).

  In the server connection status update process, as shown in FIG. 9, the CPU 101 performs connection confirmation (life check) for all servers, and tries connection processes for unconnected servers (step S71). Next, the CPU 101 sets a connection monitoring timer (step S72), and determines whether there is a connection notification from the server (step S73). If there is a connection notification, the CPU 101 updates the “status” of the server management table to “connected” for the server with a response (step S74). If there is no connection notification from the server in step S73, the process in step S74 is passed. Next, the CPU 101 determines whether or not the set connection monitoring timer has timed out (step S75). If the connection monitoring timer has not timed out, the process returns to step S73, and if it has timed out, the periodic check timer is set (step S76).

  Here, returning to FIG. 7, the CPU 101 determines whether or not there is a search request from the terminal control program 56 (step S34), and if there is a search request, the status of each server in the server management table in the work table WORK1. Is set (step S35). Next, the CPU 101 refers to the work table WORK1 and transmits a search request together with the slip number of the search condition to all connected servers and waits for a response (step S36). First, the CPU 101 determines whether or not responses have been completed from all the requested servers (step S37). If not completed, the CPU 101 determines whether or not there is a response from the servers (step S38). The process returns to S37. In step S38, if there is a response from the server, the CPU 101 determines whether there is data (slip image data) (step S39), and if there is data, notifies the terminal control program 56 of the received data ( Step S40) and the process returns to step S34. If there is no data in step S39, the CPU 101 returns to the process of step S37.

  In step S37, when responses from all the requested servers are completed, it is determined whether there is an unconnected server with reference to the work table WORK1 (step S41). If there is no unconnected server, the CPU 101 notifies the terminal control program 56 of “no data” (step S42), and returns to the process of step S34. If there is an unconnected server, the CPU 101 refers to the work table WORK1 and notifies the terminal control program 56 of information indicating that the “unconnected” server is being connected (step S43).

  Next, the CPU 101 increments the variable n of the connection processing number (step S44), saves the data of the work table WORK1 together with the slip number of the search condition in another work table WORK2 (step S45), and then proceeds to step S34. Return to processing. Note that the work table WORK2 [n] is saved by sequentially adding the data of the work table WORK1 when there is a search request and there is no data in the connected server and there is an unconnected server. .

  Next, when there is no search request in step S34, the CPU 101 determines whether or not the periodic check timer set at the end of the server connection state update process has timed out (step S46). The process returns to S34. If the periodic check timer has timed out, the CPU 101 executes server connection status update processing (step S47), and determines whether there is any save data in the work table WORK2 (step S48). If there is no save data in the work table WORK2, the CPU 101 returns to the process of step S34, and a series of processes related to the search request ends, and the next search request is awaited. Meanwhile, in step S47, the CPU 101 constantly monitors the connection state of the server, and if an unconnected server is detected, the CPU 101 executes reconnection processing on the unconnected server.

  If it is determined in step S48 that there is saved data in the work table WORK2, the search request is not made to the unconnected server, and the process is continued for the unconnected server. First, in order to process the first saved data, the CPU 101 assigns an initial value 1 to the variable m of the work number (step S49), and then determines whether the m is greater than n (step S49). S50).

  If it is determined in step S50 that m is smaller than n, the CPU 101 changes the saved data of the work table WORK2 [m] to “not connected” and changes the “status” in the server management table to “connected”. It is determined whether or not the server is a failed server (step S51). If the server is in the connected state, the CPU 101 changes the saved data in the work table WORK2 [m] to “connected” (step S52). As a result, the “unconnected” servers are eliminated from the work table WORK2 [m], and only the “unconnected” servers that have not been searched yet are narrowed down.

  Next, the CPU 101 transmits a search request together with a slip number to all the connected servers and waits for a response (step S53). First, the CPU 101 determines whether or not there is a response from all the servers that requested the search (step S54). If there is no response from all the servers that are currently connected, the CPU 101 determines whether or not there is a response from the server (step S55). If there is no response, the process returns to step S54. In step S55, if there is a response from the server, the CPU 101 determines whether there is data (slip image data) in the response (step S56). If there is data, the CPU 101 stores the slip number saved in WORK2 [m]. The received data is notified to the terminal control program 56 (step S57). If there is no data in the response in step S56, the CPU 101 returns to the process of step S54.

  In step S54, if there is a response from all the requesting servers that are connected, it is determined whether there is an unconnected server (step S58). If there is no unconnected server, the CPU 101 notifies the terminal control program 56 of “no data” (step S59). The processing on the terminal control program 56 side with respect to the processing in steps S57 and S59 is not particularly shown in FIG. 6, but the received response data (slip image data) or “no data” response is suspended. ing. For example, when the operator is engaged in another job, the search result that is put on hold may be displayed on the screen when the job is completed.

  In step S51, if there is no connected server, in step S58, if an unconnected server remains, the CPU 101 increments the variable m (step S60) and returns to the process of step S50. At this time, since the variable m is incremented, in step S50, when the condition of n <m is satisfied, the process returns to step S34.

  As described above, when there is no corresponding search data in the first search and there is an unconnected server, the terminal 50 displays that the connection process is in progress and apparently ends the process. However, in practice, the processing for this search request continues until a final search result is obtained in the background, and the search result is put on hold. That is, in the background process, a search request is made only to the server that has been updated from the unconnected state during the server connection state update process, and if the search data is found there, the received data is notified to the terminal control program 56. . If the search data is not found, the search request is made to the connected server until there is no unconnected server. If a server with the search data is found on the way, the received data from there is sent to the terminal. The control program 56 is notified. Eventually, all servers are connected, and even if a search is made, if no server with search data is found, “no data” is notified. The received data or information without data notified to the terminal control program 56 is reserved and used when necessary.

  FIG. 10 is a flowchart showing the flow of processing of the server processing program. Note that the servers 10, 20, and 30 are also configured with the same hardware as the hardware shown in FIG. 3, and therefore the following processes are performed by the CPU.

  In the server, first, the CPU determines whether or not there is a search request from the terminal 50 as a client. If there is no search request, the CPU waits until there is a search request (step S81). When receiving the search request from the terminal 50, the CPU searches the slip database using the received slip number as a search key (step S82).

  Next, the CPU determines whether there is search data as a result of searching the slip database (step S83). If there is search data, the CPU extracts the slip image data of the corresponding slip number from the slip database (step S84), and performs a data check to determine whether the slip number of the extracted data matches the slip number requested to be searched. (Step S85). Thereafter, the CPU transmits the slip image data after the data check to the terminal 50 as a response to the search request, or transmits a message with no data to the terminal 50 (step S86), and returns to the process of step S81.

  In the second embodiment, the terminal control program 56 and the communication program 57 are separately configured. However, as in the first embodiment, the terminal control program 56 and the communication program 57 communicate with each other. The program 57 may be integrated.
