Description

  The present invention relates to a technology for controlling the use of a service by a user in a server system that provides a service via the Web, and in particular, to a server system that provides a plurality of services having different time periods that can be provided and user authority. It is related to effective technology.

  A server system that provides a service to a user using the Web generally interacts with a client terminal used by the user, performs a process related to session management, screen generation, and the like, and a service (business) to be provided It has a so-called three-layer structure that is functionally divided into an application server that performs business processing unique to the database and a DB server that holds various data necessary for business processing as a database.

  Depending on the scale of the service to be provided, in order to process a certain service (for example, stock order), the application server usually provides multiple application servers that provide subdivided unit operations. A series of processing is performed by calling a plurality of business modules operating on the above sequentially or in parallel to perform processing for a large-scale service.

  In such application servers and business modules that process unit business, service stop time is provided in advance for each application server or business module in order to periodically secure time for maintenance, batch processing, etc. When a business process request is received during this period, it is necessary to respond to an error outside the service time each time, and there is a problem that an extra load is applied to the application server or business module.

In response to such a problem, Japanese Patent Application Laid-Open No. 2007-241510 (Patent Document 1) describes a business control system interposed between a Web server and an application server, and includes a business process and a processing order. A processing sequence TBL that stores a processing sequence that defines a service time, a service time TBL that stores a service provision time zone and a corresponding processing sequence, and whether or not a requested service can be provided based on the current time for the requested service There is disclosed a server system that includes means and controls so that a processing request is not transmitted to an application server during a service stop time.
JP 2007-241510 A

  A company portal site or the like is provided so that a plurality of services can be used for a user. In the midst of this, 24 hours of service provision has been promoted in order to improve and expand service content. In that case, there are services that can be provided 24 hours a day, such as browsing and inquiring information, for example, stock trading, etc., where actual services are not performed for 24 hours, system maintenance, batch processing, etc. Some services are periodically stopped, and not all services can be provided 24 hours a day. Further, there may be a case where only a specific service cannot be temporarily provided due to a system failure or an overload.

  In such a situation, when a user accesses a service that cannot be provided at that time, in the server system according to the prior art, whether the service can be provided based on the service time of each application server or business module in the business control system. It can be avoided that a request is sent to the application server and an extra load is applied.

  However, unnecessary access from the Web server to the business control system occurs. In addition, for example, when the services that can be provided differ depending on the authority and attributes of each user, and the route (channel) for accessing the desired service by the user is, for example, a personal computer or mobile phone at home, or a corporate sales office If there are multiple terminals such as terminals installed in a store, mobile terminals held by salespersons, etc., and there are individual application servers and business modules for each channel, a conventional business control system In this case, it is impossible to determine whether or not the service can be provided, and it is necessary to create a determination unit individually in the application server or the business module. Further, when viewed from the user, it is unclear whether or not the service can be used until the desired service is actually accessed, and the convenience is not high.

  Accordingly, an object of the present invention is to determine whether or not each service can be provided in a server system that provides a plurality of services having different time periods and user authorities that can be provided according to the user authority, time periods, and access channels. The menu of services that can be provided is controlled to be presented to the user, and control is performed so that unnecessary access to the application server does not occur even when the user accesses a service that cannot be provided. It is to provide a server system.

  The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.

  Of the inventions disclosed in this application, the outline of typical ones will be briefly described as follows.

  A server system according to a representative embodiment of the present invention includes a Web server, an application server, and a DB server, and a plurality of services processed by the application server and the DB server are transmitted to a client terminal via the Web server. In the server system to provide, the Web server holds, for each service, a session management table that holds information about a session with the client terminal, and a time zone in which the service can be provided to the client terminal. Based on a comparison between a service time management table and information on a time zone in which the service time management table can provide the service for the service that has received a use request from the client terminal, and a current time Whether or not And when the service control unit determines that the service cannot be provided when the service use request is received from the client terminal, the service cannot be provided. A response to the effect is transmitted to the client terminal.

  Among the inventions disclosed in the present application, effects obtained by typical ones will be briefly described as follows.

  According to a typical embodiment of the present invention, in a server system that provides a plurality of services having different time zones that can be provided and user privileges, etc. Since it is possible to determine whether or not to provide a service and present a menu of services that can be provided to the user, it is possible to improve the convenience of the user when using the service.

  In addition, according to the representative embodiment of the present invention, even when there is a use request from a user for a service that cannot be provided, control can be performed so that unnecessary access to the application server does not occur. Therefore, it is possible to reduce the load on the application server.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiment, and the repetitive description thereof will be omitted.

<Embodiment>
A server system according to an embodiment of the present invention has a three-layer structure of a Web server, an application server, and a DB server, and a plurality of services processed by the application server and the DB server are sent to a client terminal via the Web server. It is a server system to provide.

  The server system according to the present embodiment determines whether each service can be provided according to the user authority, the time zone, and the access channel when providing a plurality of services having different available time periods, user authority, etc. Controls the menu of services that can be determined and provided to the user, and prevents unnecessary access to the application server even if there is a user request for a service that cannot be provided. Control.

  In the description of the server system according to the present embodiment, “service” refers to a unit business realized by a series of processes including a request from a user (client) and a response to the request. This includes order processing in stock trading systems, portfolio analysis, simulations, balance inquiry and transfer processing in internet banking systems, and account information inquiries.

  In addition, the “channel” is a route through which a user tries to use a desired service. For example, a personal computer or a mobile phone at home, a terminal installed in a company sales office or store, It differs depending on the usage environment such as a portable terminal held by a salesperson or the like, and may differ depending on which Web site has linked to the Web site providing the service. The channel can be identified by a URL (Uniform Resource Locator) when the user accesses the server system of the present embodiment.

<System configuration>
Hereinafter, the system configuration of the server system of this embodiment will be described.

  FIG. 1 is a diagram showing an outline of a configuration example of a server system according to the present embodiment. The server system includes a presentation logic (PL) server 100 corresponding to a Web server in a three-layer structure, a business logic (BL) server 200 corresponding to an application server, and a DB server 300. Each server may be physically constructed in a separate device, or a part or all of the servers may be logically divided into the same device. When the server is physically constructed by another device, each server is connected by a LAN or the like.

  The client terminal 600 is connected to the server system of the present embodiment via the PL server 100 via the network 500 such as the Internet or an intranet. The client terminal 600 provides a service using the Web by a Web browser or other application, such as a personal computer or mobile phone at home, a terminal installed in a company sales office or store, or a mobile terminal owned by a salesperson. Various devices that can be received are applicable.

  The PL server 100 is configured to include a channel control function 110, an authentication function 120, a service control function 130, an external linkage function 140, a PL server base unit 150, and a screen control unit 160. Furthermore, the PL server infrastructure unit 150 includes a channel controller 151, an authentication unit 152, a service controller 153, a business infrastructure unit 154, a channel management TBL 155, a service time management TBL 156, and a session management TBL 157.

  The channel control function 110 identifies the access channel (URL) received from the client terminal 600 by the function of the Web server of the PL server 100, and the channel control unit 151 of the PL server base unit 150 performs according to the contents of the channel management TBL 155. Controls whether services can be provided on a channel basis. The channel control function 110 defines information on available channels (URLs).

  The authentication function 120 identifies whether or not various kinds of authentication are necessary when accessing from the client terminal 600, and performs authentication by the authentication unit 152 of the PL server base unit 150. Examples of authentication here include authentication using a digital certificate, authentication using a one-time password, authentication using a cookie, and other channel-specific authentication.

  The service control function 130 identifies the service to be used from the client terminal 600, and the service control unit 153 of the PL server base unit 150 uses the service time management TBL 156 and the session management TBL 157 for each service according to the contents of the time zone and user. The service availability is controlled based on the authority. The service control function 130 defines service information that can be provided as a system. In addition, the service control unit 153 holds information related to the session with the client terminal 600 in the session management TBL 157, and performs session management such as taking over session information and managing the number of sessions for each service.

  When the service to be used can be provided from the client terminal 600, the service control function 130 calls the BL server 200 that processes the service and requests a business process. When the service to be used from the client terminal 600 is the external service 400 provided by a system external to the server system according to the present embodiment, the external link function 140 is called instead of the BL server 200. The external linkage function 140 provides a service by requesting processing to the corresponding external service 400 by the business platform unit 154 of the PL server platform unit 150 to cooperate.

  At this time, it is also possible to realize single sign-on by signing on to the target external service 400 by the business infrastructure unit 154 using the session information of the session management TBL157. Examples of such external service 400 include stock price information provided by a financial service company and various simulation services.

  Based on the result of the business processing performed by the BL server 200 or the external service 400 in accordance with the service use request from the client terminal 600, the screen control unit 160 uses the screen data for response from the stored screen file ( HTML (HyperText Markup Language) data) is generated. The generated screen data is transmitted to the requesting client terminal 600 by the function of the Web server of the PL server 100, and is displayed by the Web browser of the client terminal 600 or another application.

  The BL server 200 has a configuration including a business control unit 210 and a business module 210. Further, the business control unit 210 has a time control unit 211 and a business service control unit 212. In the BL server 200, as described in the prior art, a plurality of business modules 220 required to execute a service requested from the client terminal 600 are sequentially or in parallel according to control by the business control unit 210. Executed. In addition, a service may be executed by cooperation of business modules 220 in a plurality of BL servers 200.

  The time control unit 211 of the business control unit 210 holds the usable time of each business module 220 and determines whether or not the requested service can be executed at this time based on this information. When the requested service is executable, the business service control unit 212 of the business control unit 210 executes the necessary business module 220 according to the processing sequence. Each business module 220 accesses the business DB 310 managed by the DB server 300 to read / write data necessary for executing business processing, and executes business processing.

  The characteristic configuration of the server system of the present embodiment is that the channel control function 110, the channel control unit 151, the channel management TBL 155, the service control function 130, the service control unit 153, and the service in the PL server 100 are as follows. These are each part of time management TBL156 and session management TBL157. The PL server 100 determines whether or not the service can be provided by controlling whether or not the service can be provided on a channel basis, and whether or not the service can be provided on a service basis based on the time zone, user authority, session information, and the like. It determines and controls so that the process request about the service which cannot be provided is not transmitted to the BL server 200. Details of this control will be described later.

<Data structure>
Hereinafter, the configuration of each table that is held in the PL server base unit 150 of the PL server 100 and holds data used when the server system of the present embodiment performs service control will be described.

  FIG. 2 is a diagram illustrating a data configuration example of the channel management TBL 155. The channel management TBL 155 has URL and data items for availability. The URL is a URL used when the user accesses the server system according to the present embodiment from the client terminal 600, and has a different value for each access channel. The availability is data indicating whether or not the channel specified by the corresponding URL is currently available. For example, when a channel with a low priority is disabled on a channel basis due to a system failure or the like, the availability value is disabled.

  FIG. 3 is a diagram illustrating a data configuration example of the service time management TBL 156. The service time management TBL 156 has data items of service name, attribute, and service time. The service name is data representing the name of each service provided by the server system of the present embodiment. The attribute is data representing attribute information determined by the authority of a user who can use the service.

  The service time is data representing a time zone in which the service can be provided. For example, when the service provision time is changed due to irregular maintenance in the BL server 200, or when the corresponding service is temporarily unavailable due to a failure or the like, the service time value is changed. By making it outside the provision time, it is possible to disable the service.

  FIG. 4 is a diagram illustrating a data configuration example of the session management TBL 157. The session management TBL 157 includes data items of session ID, URL, ID, session attribute, and update date / time. The session ID is a session ID assigned to identify a session established by a successful login from the client terminal 600 to the server system of the present embodiment by the user.

  The URL is a URL representing a channel through which the session is established. The ID is a user ID of a user who has logged into the server system of the present embodiment and established the session. The session attribute is data representing a session attribute (authority) determined by a user attribute or a channel of the session. The update date / time is a time stamp when the entry of the session in the session management TBL 157 is updated, and is data used for grasping the active state of the session.

  The data items of each table shown in FIGS. 2 to 4 are not limited to those shown in the drawings, and may include other data items. In addition, various methods such as a database, a file, and a memory table can be used for mounting each table.

<Login process>
Hereinafter, an example of service control when the user logs in to the server system of the present embodiment from the client terminal 600 will be described with reference to FIG. In the following description, in order to explain characteristic processing in the server system of the present embodiment, for example, processing in the authentication function 120 and the authentication unit 152, processing in the business control unit 210, and the like are omitted. Describe.

  Before login, for example, a list of service names and service provision times are displayed on the portal site, etc., in a form that is classified by service available time zone based on the service time information acquired from the service time management TBL 156. You may be made to do.

  When the PL server 100 receives a login request to the server system of the present embodiment from the client terminal 600, the login request includes a URL (channel), a user ID, and a password (PWD). The login request is transmitted to the BL server 200 that performs login processing via the PL server 100 and is passed to the business module 220 that performs login processing.

  In the business module 220, for example, a password and attribute (authority) information are acquired from a business DB 310 (for example, an account information DB) that holds user attribute information using an ID as a key, and login processing is performed by collating the password. (S501). When the login process is successful, a login response including information such as URL, ID, and attribute information acquired from the business DB 310 is transmitted to the PL server 100 via the BL server 200.

  In the PL server 100 that has received the login response, the service control unit 153 assigns a session ID, and writes data such as a session ID, URL, ID, and session attribute in the session management TBL 157 (S502).

  Further, the service control unit 153 obtains a list of service names and service times of services that can be currently provided for the user attribute from the service time management TBL 156 based on the attribute and the current time (S503). Based on this list, for example, a list of services currently available to the logged-in user and their available time zones can be displayed on the screen after login, or only a menu of services currently available to the logged-in user can be selected. Can be displayed. Such processing is not limited to the time of login, but can be performed at any time when the result of other service processing is returned from the PL server 100 to the client terminal 600 or when the main screen is displayed.

  As a result, the user can know whether or not the service can be used without actually requesting the use of the service. However, even in this case, for example, there may be a case where a use request is made for a service that cannot be used due to a time difference between the time when the login result screen is displayed and the time when the user actually requests use of the service. In such a case, when a service use request is made, the PL server 100 controls whether or not the service can be provided by a process described later.

  Due to the success of the login process, the session ID is transmitted from the PL server 100 to the client terminal 600 in addition to the screen data. Thereafter, the service control unit 153 and the session management TBL 157 perform session management that identifies a session for using the service by the user using the session ID.

<Service processing>
Hereinafter, an example of service control when a user accesses a server system of the present embodiment from a client terminal 600 and uses a desired service will be described with reference to FIG.

  When the PL server 100 receives a service processing request from the client terminal 600 to the server system of the present embodiment, the service processing request includes a URL (channel), a service name, and a session ID. In the PL server 100 that has received the service processing request, the channel control function 110 identifies the channel from the URL, and the channel control unit 151 obtains the availability from the channel management TBL 155 using the URL as a key, and determines whether the channel is available. (S601). Processing when the channel is unavailable will be described later.

  If the channel is available, the service control function 130 identifies the service from the service name, and the service control unit 153 acquires the session attribute and the like from the session management TBL 157 using the session ID as a key (S602). Further, the service time management TBL 156 acquires the attribute and service time using the service name as a key, and compares the session attribute and the current time with each other to determine whether the service can be provided (S603). Processing when the service cannot be provided will be described later.

  If the service can be provided, the service processing request is transmitted to the BL server 200 that processes the service, and is passed to the business module 220 that processes the service. In the business module 220, if necessary, the business DB 310 is accessed, data is read and written, and service processing is executed (S604). When the service processing is completed, a service processing response including the processing result is transmitted to the PL server 100. In FIG. 6, the case where the service processing is performed by the BL server 200 is taken as an example, but the same applies to the case where the processing is performed by the external service 400.

  In the PL server 100 that has received the service processing response, the service control unit 153 updates the time stamp of the update date and time of the corresponding record in the session management TBL 157 with the current time (S605). Thereafter, the PL server 100 generates screen data as a processing result by the screen control unit 160 and transmits the screen data to the client terminal 600.

<When service cannot be provided>
Hereinafter, an example of control when the user cannot provide the corresponding service when the user accesses the server system of the present embodiment from the client terminal 600 and uses the desired service will be described with reference to FIG. As in the case of the service processing, when the PL server 100 receives a service processing request from the client terminal 600 to the server system of this embodiment, the channel control function 110 and the channel control unit 151 determine whether or not the channel can be used. If the channel is available, the service control function 130 and the service control unit 153 determine whether the service can be provided (S602, S603).

  If it is determined that the service cannot be provided, the PL server 100 generates screen data indicating that the service cannot be provided by the screen control unit 160 and transmits the screen data to the client terminal 600. Accordingly, the service processing request is not transmitted to the BL server 200 or the external service 400, and it is possible to control whether or not the service can be provided without causing unnecessary access to the BL server 200 or the external service 400. .

  Note that, for example, in the case of temporarily disabling the corresponding service such as irregular maintenance in the BL server 200, failure, traffic overflow, etc., the service time in the entry of the corresponding service in the service time management TBL 156 This can be realized by changing the service time to be outside the service provision time. The service time can be changed automatically, for example, triggered by the detection of a failure in the BL server 200 or the like, or manually by an operator.

<When channel is unavailable>
Hereinafter, when a user accesses the server system of the present embodiment from the client terminal 600 and uses a desired service, FIG. 8 is used as an example of control when the channel used for access by the user is unavailable. I will explain.

  As in the case of the service processing described above, when the PL server 100 receives a service processing request from the client terminal 600 to the server system of the present embodiment, the channel control function 110 and the channel control unit 151 determine whether or not the channel can be used. Determination is made (S601).

  If it is determined that the channel used for access by the user is unavailable, the PL server 100 generates screen data indicating that the service cannot be provided by the screen control unit 160, and the client terminal 600 Send to. Accordingly, the service processing request is not transmitted to the BL server 200 or the external service 400, and it is possible to control whether or not the service can be provided without causing unnecessary access to the BL server 200 or the external service 400. .

  For example, when a channel with a low priority is temporarily unavailable on a channel basis due to a system failure or the like, it is realized by changing the value of availability of the corresponding channel in the channel management TBL 155 to unavailable. be able to. The change of the availability value can be automatically performed using, for example, detection of a system failure or the like as a trigger, or can be manually performed by an operator.

  As described above, according to the server system of the embodiment of the present invention, when providing a plurality of services having different time zones that can be provided, user authority, etc., in the PL server 100 that is a Web server, Since it is possible to present to the user a menu of services that can be provided by determining whether each service can be provided according to the user's attributes (authorities), time zones, and access channels, the convenience of the user when using the service It becomes possible to improve the nature.

  Further, even when there is a use request from a user for a service that cannot be provided, it is possible to control the BL server 200 and the external service 400 so that unnecessary access does not occur. It becomes possible. In addition, since the PL server 100 controls access to services according to such channels and user attributes, for example, the BL server 200 has a function for controlling access to services for each channel or user. There is no need to mount each attribute individually, and the BL server 200 can be shared.

  As mentioned above, the invention made by the present inventor has been specifically described based on the embodiment. However, the present invention is not limited to the embodiment, and various modifications can be made without departing from the scope of the invention. Needless to say.

  The present invention can be used in a server system that provides services via the Web.
