Description

  The present invention relates to a client server system and a method for expanding the client server system, and more particularly to a client server system that can easily perform system expansion and a method for expanding the system.

  In a client server system typified by a web system on the Internet, when a client accesses a predetermined server and requests processing, the server executes processing in response to this request and transmits the result to the client. In a client / server system, when processing requests increase, it is required to expand the system as the processing requests increase.

  System expansion in a conventional client-server system will be described. FIG. 1 is a block diagram showing a configuration of a conventional client server system. Referring to FIG. 1, a conventional system includes a client terminal 107, a first processing device 101 and a second processing device 102 corresponding to an AP server (application server) that normally performs business processing, and a DB server that performs database processing. A third processing device 103 corresponding to (database server) and a shared resource 104 are included. The general system configuration as shown in FIG. 1 often has a two-layer configuration of an AP layer and a DB layer. The shared resources used in the system are arranged in a single DB server. When expansion is performed by increasing the processing amount, the AP server uses a method of adding (scaling out) a server as the amount of input data 4 increases. Referring to FIG. 1, the conventional system can add a fourth processing device 105 in response to an increase in processing amount.

  In addition to the above-described methods, techniques described in Patent Documents 1 to 3 below are known as methods for expanding the system.

  In the technique described in Patent Document 1 (Japanese Patent Laid-Open No. 2002-140213), a multi-tier information management server and a virtual disk server are connected via the Internet, and a first PC and a second PC are multi-tier information management servers. And we are building a system. Users of the first PC and the second PC can write files that need to be backed up, shared with other PC users from the PC side to the server side, and are managed by the multi-tier information management server. Is read to the PC side. Here, in particular, the multi-tier information management server periodically detects the percentage of free space on the HDD, and backs up and saves backup files and shared files on the HDD to the virtual disk server according to the percentage of free capacity. Disclosed is a technique for restoring a file on an HDD.

  The technology described in Patent Document 2 (Japanese Patent Application Laid-Open No. 2002-163241) aims at dynamically reconfiguring resources on the service providing side according to demand fluctuations, and requests from a plurality of clients (services) Request) is distributed to one of the servers operating in the server cluster by the load balancer. In Patent Document 2, when the access increases or decreases in such a case, the management module instructs to change the configuration of the server cluster, and causes the server to be added to the server cluster or the server to be deleted from the server cluster. It discloses a possible technology.

  Japanese Patent Laid-Open No. 04-020153 discloses a technique for controlling communication between a host computer and a data processing node by performing protocol conversion and data length conversion of a lower node. .

  In the prior art as described above, the shared resource becomes a single shared resource in the system processed by all the input data 4. At this time, since there is a single shared resource, the DB server must also be a single one. When considering system expansion, only a method of scaling up the DB server can be used. This limits the scalability of the system. In other words, since a database that is a shared resource cannot be divided, only the method of improving (scaling up) the server capacity of one unit can be taken.

  Referring to FIG. 1, the conventional system configures the extended third processing device 106 by improving the processing performance of the third processing device 103, thereby realizing the extension of the DB layer. Improving server capability does not mean that database performance is improved linearly due to database buffer control, log output, write I / O, index contention, and the like. Therefore, there is a limit to the expandability of the conventional system.

  In a system including shared resources, a technique that can appropriately expand the system without causing shared resource competition is desired.

  According to the present invention, in a system including shared resources, the system can be appropriately expanded without causing shared resource competition. Even when the shared resource is a resource that is an object of update processing, the system can be expanded without causing a shared resource conflict.

  The client server system described in the present embodiment divides and holds the shared resource by a specific data division method in order to ensure the expandability of the shared resource (database or the like) processed by the input data 4. As a result, a flexible system expansion method is realized. In other words, a shared resource that is configured in a single unit in the system is divided and arranged for each server to configure the system, and predetermined processing is executed corresponding to the configuration. As a result, the expandability of the system configuration of the client server system of the present embodiment is ensured.

  Here, an outline of the concept of shared resource division in the present embodiment will be described. The client server system according to the present embodiment divides processing in the system into processing units called a plurality of services, and performs processing in stages. Hereinafter, the service performed in stages is defined as a stage. In the present embodiment, the shared resource is an axis (stage division) that is divided by the shared resource unit processed in each stage, and the shared resource in the stage is called a shared resource processed by some input data 4 It is held in a state of being divided by the axes (data division) grouped from the viewpoint.

  FIG. 2 is a data model (conceptual diagram) illustrating the relationship between the input data 4 and the shared resources in the system when the shared resources are divided in this way. In the following description, the case where the client server system in the present embodiment is a system that executes information processing in three stages in response to input data 4 to be input will be described as an example.

  As described above, the client server system according to the present embodiment is grouped by the axis (stage division) for dividing data in units of stages (services) provided in the system and the shared resources operated by the input data 4 in the stage. The shared resource is divided and held by the axis to be converted (data division). Here, since the divided shared resources are grouped as shared resources handled by the input data 4, the divided shared resources are hereinafter referred to as group information. As shown in FIG. 2, the shared resources of the present embodiment are held as a set (5, 6, 7) for each shared resource used in each stage.

  Referring to FIG. 2, the first service shared resource 5 includes first group information 5-1, second group information 5-2, and third group information 5-3. As shown in FIG. 2, in order to perform the process corresponding to the first stage 1, the process corresponding to at least one shared resource of the first group information 5-1 to the third group information 5-3 is performed. . Similarly, the second service shared resource 6 includes fourth group information 6-1, fifth group information 6-2, and sixth group information 6-3, and the third service shared resource 7 includes , Seventh group information 7-1, eighth group information 7-2, and ninth group information 7-3.

  Moreover, the input data 4 of this Embodiment is comprised as a group of the some small data shown by the 1st data 4-1-the 6th data 4-6. When information processing is executed in response to the input data 4, small data processed in each stage (5, 6, 7) and group information (5-1 to 5-3, 6) used for processing the small data -1 to 6-3 and 7-1 to 7-3) are associated in advance.

  For example, the first group information 5-1 used when executing the first service is used for processing the data corresponding to the first data, the second data 4-2, and the third data. It is shown to be used as a shared resource. In other words, for example, it can be said that the first group information 5-1 is a shared resource having the first data, the second data 4-2, and the third data as members of the group.

  Further, for example, the information processing corresponding to the second data 4-2 uses the first group information 5-1 of the first service, the fourth group information of the second service, and the ninth group information of the third service. It is shown to be information processing. In other words, the second data 4-2 is data belonging to each shared resource group of the first group information 5-1, the fourth group information, and the ninth group information.

  FIG. 3 is a block diagram illustrating a configuration of the client server system according to the present embodiment. The system illustrated in FIG. 3 is a system that executes information processing corresponding to the data model illustrated in FIG. Referring to FIG. 3, the client server system according to the present embodiment is divided into a first stage 1, a second stage 2, and a third stage 3 as stages for processing input data 4, and in each stage, a first service is provided. The second service and the third service are provided.

  Referring to FIG. 3, the first stage 1 (first service) includes a first stage side first processing device 8 and a first stage side second processing device 9 as devices for processing the input data 4. Yes. Each service processing device (8, 9) is connected to a corresponding information storage unit. Referring to FIG. 3, the first stage side first processing device 8 is connected to the first storage unit 10, and the first stage side second processing device 9 is connected to the second storage unit 11. As shown in FIG. 3, the first storage unit 10 stores first group information 5-1 operated by the first stage side first processing device 8. The second storage unit 11 stores second group information 5-2 and third group information 5-3.

  Similarly, the second stage 2 (second service) includes a second stage side first processing device 12 and a second stage side second processing device 1313. Referring to FIG. 3, the second stage side first processing device 12 is connected to the third storage unit 14, and the second stage side second processing device 13 is connected to the fourth storage unit 15. Fourth group information 6-1 is stored in the third storage unit 14, and fifth group information 6-2 and sixth group information 6-3 are stored in the fourth storage unit 15. Further, the third stage 3 (third service) includes a third stage side first processing device 16, a third stage side second processing device 17, and a third stage side third processing device 18. Referring to FIG. 3, the third stage side first processing device 16 is connected to the fifth storage unit 19. The third stage side second processing device 17 is connected to the sixth storage unit 20, and the third stage side third processing device 18 is connected to the seventh storage unit 21. As shown in FIG. 3, the fifth storage unit 19 stores seventh group information 7-1. Similarly, the sixth storage unit 20 stores the eighth group information 7-2, and the seventh storage unit 21 stores the ninth group information 7-3.

  Further, it is assumed that the client server system of the present embodiment executes information processing in response to input data 4 supplied from “22”. “22” illustrated in FIG. 3 is not limited to one, but may be configured to include a plurality of “22” connected via a network, for example.

  When processing the group information with the input data 4, the service processing devices in the first stage 1 are processed in order. Hereinafter, a technique for selecting which service processing device group information the input data 4 should process will be described. As described above, the group information is arranged in each service processing apparatus that processes the group information. When the input data 4 operates on the group information, the input data 4 is transferred to the service processing apparatus in which the group information exists. In order to transfer the input data 4 to an appropriate service processing device, a mechanism called a next service determination logic unit 27 is provided in the service processing device. As a result, the group information divided and arranged in each service processing apparatus can be processed as a shared resource of the plurality of input data 4.

  FIG. 4 is a block diagram illustrating one of the plurality of service processing devices (8, 9, 12, 13, 16, 17, 18) described above and illustrating the configuration thereof. The plurality of service processing apparatuses in the present embodiment transfer data from each stage to the next stage. The configuration for the data transfer is the same in each service processing apparatus. Therefore, in the following description, the internal configuration is described corresponding to an arbitrary processing apparatus (nth stage side nth processing unit 25: n is an arbitrary natural number) without specifying a stage or the like.

  As described above, the n-th stage-side n-th processing unit 25 illustrated in FIG. 4 is one of processing apparatuses provided in an arbitrary stage. Referring to FIG. 4, the n-th stage-side n-th processing unit 25 includes two logics, that is, a process execution unit 26 and a next service determination logic unit 27. The process execution unit 26 is a logic for operating group information. The next service determination logic unit 27 is a logic that determines which group information is to be operated by the service processing apparatus at which stage the input data 4 is next. As shown in FIG. 4, the next service determination logic unit 27 determines the next service based on the next service determination information 31 stored in the next service determination information storage unit 30, and determines the determined transfer destination. For example, data is transmitted to the first processing device 32 on the (n + 1) th stage side and the second processing device 33 on the (n + 1) th stage side. The next service determination information 31 includes information indicating which service processing apparatus the data model and group information representing the relationship between the group information and the input data 4 shown in FIG.

  The operation of this embodiment will be described below. FIG. 5 is a sequence diagram illustrating the operation of this embodiment. FIG. 5 illustrates a flow of processing in which group information distributed and arranged in the service processing device is operated by the second data 4-2 when the second data 4-2 is input from the terminal device 22. .

  In the transmission operation F01, the second data 4-2 is input from the terminal device 22 to the first stage side first processing device 8 of the first stage 1.

  In step S101, the first processing apparatus 8 on the first stage side operates the first group information 5-1 using the second data 4-2. When the information processing in step S101 is completed, the process proceeds to step S102. In step S <b> 102, the first stage side first processing device 8 selects a processing device having group information to be processed next by the second data 4-2 in the “service determination” processing. In the “service determination” process, the service determination information held in the first stage side service determination information storage unit 30a is referred to. At this time, the next service determination logic unit 27 of the first processing device 8 on the first stage side performs the data model information indicating the relationship between the group information and the input data 4 as illustrated in FIG. 2 or the group as illustrated in FIG. The “service determination” is performed based on the information on the arrangement of the information in the service processing device.

  Here, since the 4th group information which is the group information of 2nd data 4-2 exists in the 2nd stage side 1st processing apparatus 12, 2nd data 4-2 is sent to the 2nd stage side 1st processing apparatus 12. A transfer process F02 for sending is executed.

  In step S103, the second stage-side first processing device 12 operates the fourth group information using the second data 4-2. When the process is completed, the third storage unit 14 executes a “service determination” process. In the “service determination” process executed at this time, the third storage unit 14 uses the “service determination information” stored in the second stage side secondary service determination information storage unit 30b to be processed next. To decide.

  Here, since the 9th group information which is the group information of the 2nd data 4-2 exists in the 3rd stage side 3rd processing apparatus 18, 2nd data 4-2 is sent to the 3rd stage side 3rd processing apparatus 18. A transfer process F03 for sending is executed. That is, the second data 4-2 is the third stage side third processing device 18 because the next service processing device to be processed transmits the second data 4-2 to the third stage side third processing device 18. .

  In step S105, the third stage-side third processing device 18 operates the ninth group information using the second data 4-2. When the process is completed, the process of the seventh storage unit 21 proceeds to step S106. In the “service determination” process for executing the process in step S106, the service processing apparatus to be processed next is determined using “service determination information”. At this time, since there is no next service to be processed for the second data 4-2, the process proceeds to step S107, where the process is completed.

  Hereinafter, a case where the system is expanded in the client server system of the present embodiment will be described. In this embodiment, when a system is expanded corresponding to a specific stage, the system is added by adding a processing unit similar to a processing unit (a set of a processing apparatus and a storage unit) provided in the stage. Can be extended.

  FIG. 6 is a block diagram illustrating a configuration when the expansion process of the second stage side second processing device 13 of the second stage 2 is executed in the configuration of the present embodiment. Referring to FIG. 6, a processing device (35) capable of performing the same processing as that of the second stage side second processing device 13 is prepared corresponding to the system expansion. The processing apparatus (35) is referred to as a second processing stage-side third processing apparatus 35. After configuring a new processing apparatus (third stage side third processing apparatus 35), an eighth storage unit 36 corresponding to the third stage side third processing apparatus 35 is configured. The sixth group information arranged in the database (15) of the second stage side second processing apparatus 13 is arranged in the newly prepared second stage 2 side third processing apparatus. Finally, in order to transmit the input data 4 (fifth data 4-5) for operating the sixth group information to the second processing unit 36 on the second stage 2 side, the next service determination information 31 is changed. .

  FIG. 7 is a block diagram illustrating a configuration when a new stage (service) is added in the configuration of the present embodiment. Referring to FIG. 7, a new service is added by adding one stage to be processed. For the new service, a set of service processing devices and group information (fourth stage side first processing device 38, ninth storage unit 39) is added. The ninth storage unit 39 stores shared resources (tenth group information 40). Since the input data 4 to be processed by the new service is transmitted to the fourth stage side first processing device 38, the next service determination information 31 is changed.

  As described above, the client server system according to the present embodiment can be expanded in the following two patterns. The first system extension is an extension by data division. When the processing amount from the terminal device 22 increases and the load of the service processing device in the service increases, a new service processing device is added, the group information arranged in the original service processing device is divided, and a new By disposing in a simple service processing apparatus, the service can be easily expanded. The second system extension is an extension by multi-hierarchical processing stages. When a new service is to be added, the service can be easily added by adding a stage to be processed.

  Therefore, even when the group information is distributed and arranged in the service processing devices in the system, the input data 4 is transferred to the service processing device to be processed by the “service determination information” and “service determination” logic before the distribution. As with, group information can be processed as a shared resource. Further, when the load on the processing apparatus increases, the processing capability of the system can be easily expanded by dividing the group information in the database (this is due to the data division in the stage). Furthermore, when a new service is added to the system, a service can be easily added by adding a processing device and group information as a set, and adding a stage to be processed (this means that processing in the system is a unit called a stage) By dividing by).

  In the embodiment described above, a database is used as a device for storing group information. However, in the present invention, the storage device is not limited to a database. For example, if the shared resource is a reference system and a mechanism for data protection is not required, group information is placed on a memory with low processing cost, or data protection equivalent to the database even if the group information is an update system It is also possible to combine with a mechanism for doing this. Further, although a database is used as an apparatus for storing “service determination information”, the storage apparatus is not limited to a database in the present invention. As the storage device, a memory can be used, and a distribution process to a service can be performed by logic.
