Description

  The present invention relates to a service providing apparatus, a service management method, and a program for realizing these, which provide a service according to an instruction from the outside.

  In recent years, companies have been combining a large computer called a mainframe and a general-purpose server computer called an open server in order to develop a system while making use of conventional assets (for example, (See Patent Literature 1 to Patent Literature 3.)

  In a system in which such a mainframe and an open server are combined (hereinafter referred to as “composite system”), the mainframe executes processing for core business. On the other hand, the open server executes processing for providing various services such as a database service and a Web service. In the complex system, the service provided by the open server is provided to the terminal device of the user via the main frame.

  The administrator of the complex system creates a program (hereinafter referred to as “DAA: Data Access Adapter”) in advance and registers it in the server in order to cause the server to execute the service. These DAAs are usually managed for each service group and further identified by the name of the service to be executed.

  Specifically, first, the administrator creates a service group environment by creating a directory for each service group in the server. Then, the administrator stores DAAs belonging to the service group in the directory of each service group. In addition to the DAA, a service group definition that defines the number of threads that can be executed simultaneously, execution priority, and the like is stored in each service group directory.

  Then, the user designates the service group identification name and the service identification name, and instructs the open server to execute the service. Upon receiving the instruction, the open server executes the corresponding DAA and provides a service to the user.

  By the way, when operating a complex system, when the definition of an existing service group must be changed, a new service group may need to be added (or deleted). In these cases, the administrator needs to once stop the open server, perform processing, and then start the open server again.

  However, it is difficult to stop an open server within normal business hours because it causes problems in business. For this reason, it is necessary to perform the above processing in a time zone that does not cause trouble in business such as nighttime and holidays, and there is a problem that it becomes a burden on the administrator. There is also a problem that urgent responses cannot be made.

(Embodiment)
Hereinafter, a service providing apparatus, a service management method, and a program according to an embodiment of the present invention will be described with reference to FIGS.

[Device configuration]
Initially, the structure of the service provision apparatus in embodiment of this invention is demonstrated using FIG.1 and FIG.2. FIG. 1 is a block diagram showing a configuration of a service providing apparatus according to an embodiment of the present invention. FIG. 2 is a diagram conceptually showing service groups managed by the service providing apparatus according to the embodiment of the present invention.

  A service providing apparatus 10 illustrated in FIG. 1 is an apparatus that provides a service in response to an instruction from an external user's terminal 31. In the present embodiment, as shown in FIG. 1, the service providing apparatus 10 constructs a complex system together with the main frame 20. The user terminal 31 is connected to the mainframe 20 via the network 30. Therefore, a service request from the user terminal 31 is transmitted to the service providing apparatus 10 via the main frame 20. Further, the service from the service providing apparatus 10 is provided to the terminal 31 via the main frame 20.

  As shown in FIG. 1, the service providing apparatus 10 includes a service group management unit 11. As shown in FIG. 2, the service group management unit 11 manages a service providing program (DAA) for each service group.

  In the present embodiment, an identification name is assigned to each service group and DAA, and the service group management unit 11 performs management using the identification name. As shown in FIGS. 1 and 2, identification names such as SG1 and SG2 are assigned to each service group. Each DAA is given an identification name such as service S11 or service S21. 1 and 2, n is a natural number, and m is a natural number of 1 or more and n or less.

  In addition, the service group management unit 11 receives the changed service group when any service group is changed. Then, the service group management unit 11 activates the received service group after the change, and deactivates the service group before the change.

  As described above, in the service providing apparatus 10, when the service group is changed, the service group management unit 11 can replace the service group before the change with the service group after the change. For this reason, according to the service providing apparatus 10, a service group can be changed without stopping the service providing apparatus 10.

  In addition, when a service group is newly added, the service group management unit 11 accepts the added service group and activates it. In the present embodiment, a new service group can be added without stopping the service providing apparatus 10.

  Next, the configuration of the service providing apparatus 10 will be described more specifically with reference to FIG. 3 in addition to FIGS. 1 and 2. FIG. 3 is a diagram showing a directory structure of a service group managed by the service providing apparatus according to the embodiment of the present invention.

  In the present embodiment, the service providing apparatus 10 is constructed by a server computer (see FIG. 5 described later). The DAA to be executed is described in JAVA (registered trademark).

  Furthermore, as shown in FIG. 3, in the present embodiment, the service group management unit 11 manages service groups using directories created for each service group. The directory is created on a storage area of a storage device (not shown in FIG. 1; see FIG. 7) of the server computer.

  Specifically, as shown in FIG. 3, a directory having the service group identification name as a directory name is created for each service group. Further, under each directory, a directory in which the DAA execution environment such as the definition of the service group is recorded is created. In the example of FIG. 3, “cdd”, “classes”, “conf”, “dev”, and “lib” are shown as subordinate directories.

  Among these, an item map is stored in the directory “cdd”. A class is stored in “classes”. In “conf”, information related to the definition of the service group is stored. In “lib”, various jar files are stored. Further, directories “src” and “cobol” are further created under “dev”. In “src”, a Java source that is a source of the DAA class is stored. In “cobol”, a COBOL source that is the basis of the item map is stored.

  As shown in FIG. 1, in the present embodiment, the service providing apparatus 10 includes a service group construction unit 12, a storage unit 13, and a program execution unit 14 in addition to the service group management unit 11. Yes. Further, a terminal for system administrators (hereinafter referred to as “management terminal”) 16 and a database management system (DBMS: Data Base Management System) 15 are connected to the service providing apparatus 10.

  When a change is made to the service group, the service group construction unit 12 accepts a change to the service group, constructs a service group after the change, and deploys it to the execution environment of the service providing apparatus 10.

  Specifically, in the present embodiment, when the system administrator instructs the change of the service group SGm via the management terminal 16, for example, the service group construction unit 12 reflects the instructed change. A directory for the service group SGm is created. Then, the service group construction unit 12 notifies the service group management unit 11 that the directory has been created, and stores the created directory in the storage unit 13. The storage unit 13 is created on a storage area of a storage device of a server computer (not shown in FIG. 1, see FIG. 5).

  When the administrator instructs the addition of a service group via the management terminal 16, the service group construction unit 12 newly creates a service group directory having the instructed contents. Also in this case, the service group construction unit 12 notifies the service group management unit 11 that the directory has been created, and stores the created directory in the storage unit 13.

  On the other hand, when the administrator instructs deletion of the service group via the management terminal 16, the service group construction unit 12 notifies the service group management unit 11 of the directory of the service group instructed to be deleted.

  When the service group identification name and the DAA identification name are specified from the terminal 31 via the mainframe 20 from the terminal 31, and the DAA execution is instructed, the program execution unit 14 executes the instructed DAA. .

  In the present embodiment, a specific example of DAA includes DAA that performs operations on DBMS 15, for example, database update, reference, search, and the like. In this case, the program execution unit 14 transmits data obtained by executing DAA to the mainframe 20. Then, the main frame 20 transmits data to the terminal 31 that has instructed execution of DAA.

[Device operation]
Next, the operation of the service providing apparatus 10 according to the embodiment of the present invention will be described with reference to FIGS. In the present embodiment, the service management method is implemented by operating the service providing apparatus 10. Therefore, the description of the service management method in the present embodiment is replaced with the following description of the operation of the service providing apparatus 10.

[Device operation: When changing service group]
First, a case where the system administrator changes the service group will be described. FIG. 4 is a flowchart showing an operation when changing the service group of the service providing apparatus according to the exemplary embodiment of the present invention.

  As shown in FIG. 4, first, when the system administrator instructs the change of the service group via the management terminal 16, the service group construction unit 12 receives the change instruction (step A1). Examples of the change instruction accepted in step A1 include an item map change instruction, a class change instruction, a service group definition change instruction, and a DAA content change instruction.

  Next, the service group construction unit 12 constructs a service group after the change based on the change instruction received in Step A1 (Step A2). Specifically, in step A2, the service group construction unit 12 creates a service group directory in which the change is reflected.

  Next, the service group construction unit 12 deploys the changed service group in the execution environment of the service provision measure 10 (step A3). Specifically, in step A3, the service group construction unit 12 notifies the service group management unit 11 that the directory of the changed service group has been created, and stores the created directory in the storage unit 13.

  Next, the service group management unit 11 deactivates the service group before the change, which is the target of the change instruction (step A4). As a result, the service group before the change is separated from the execution environment, and the program execution unit 14 cannot execute the DAA included in the service group before the change.

  Next, the service group management unit 11 takes in the service group after the change deployed in step A3 and activates it (step A5). Thereby, the program execution unit 14 can execute DAA included in the changed service group.

  As described above, if steps A1 to A5 are executed, the service group before the change is replaced with the service group after the change without stopping the service providing apparatus 10. Moreover, step A4 and step A5 do not need to be performed immediately after execution of step A3, and may be performed at the best timing during operation of the service providing apparatus 10.

[Device operation: When adding a service group]
Next, a case where a system administrator adds a service group will be described. FIG. 5 is a flowchart showing an operation when adding a service group of the service providing apparatus according to the embodiment of the present invention.

  As shown in FIG. 5, when the system administrator first instructs the addition of a service group via the management terminal 16, the service group construction unit 12 accepts the addition instruction (step B1).

  Next, the service group construction unit 12 constructs a new service group instructed to add based on the addition instruction received in step B1 (step B2). Specifically, in step B2, the service group construction unit 12 is instructed to add and creates a new service group directory.

  Next, the service group construction unit 12 deploys a new service group in the execution environment of the service provision measure 10 (step B3). Specifically, the service group construction unit 12 notifies the service group management unit 11 that a new service group directory has been created, and stores the created directory in the storage unit 13.

  Next, the service group management unit 11 takes in the new service group deployed in step B3 and activates it (step B4). Thereby, the program execution unit 14 can execute DAA included in the new service group.

  Also, step B4 need not be executed immediately after execution of step B2, but may be executed at the best timing during operation of the service providing apparatus 10.

[Device operation: When deleting a service group]
Next, a case where the system administrator deletes a service group will be described. FIG. 6 is a flowchart showing an operation at the time of service group deletion of the service providing apparatus according to the embodiment of the present invention.

  As shown in FIG. 6, first, when the system administrator instructs the deletion of the service group via the management terminal 16, the service group construction unit 12 receives the deletion instruction (step C1).

  Next, the service group construction unit 12 notifies the service group management unit 11 of the service group that is instructed to be deleted in Step C1 (Step C2).

  Next, the service group management unit 11 deactivates the service group instructed to be deleted in step C1 (step C3). As a result, the service group instructed to be deleted is disconnected from the execution environment, and the program execution unit 14 cannot execute the DAA included in the service group instructed to be deleted.

  Further, step C3 need not be executed immediately after execution of step C2, but may be executed at the best timing during operation of the service providing apparatus 10.

[program]
The program in the present embodiment may be a program that causes a server computer to execute steps A1 to A5 shown in FIG. 4, steps B1 to B4 shown in FIG. 5, and steps C1 to C3 shown in FIG. By installing and executing this program on the server computer, the service providing apparatus 10 and the service management method in the present embodiment can be realized.

  In this case, a CPU (Central Processing Unit) of the server computer functions as the service group management unit 11, the service group construction unit 12, and the program execution unit 14, and performs processing. A storage device such as a hard disk of the server computer functions as the storage unit 13.
