  Hereinafter, embodiments of an information processing apparatus and a program will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a block diagram showing a configuration of a synchronous processing system according to the present embodiment. As shown in FIG. 1, the synchronization processing system 1 according to the present embodiment is connected to a server device 100, a scanner device 200, a load balance server device 300, and a secondary server device 400 via a network 10.

  The server apparatus 100 includes a synchronization source data storage unit 120 (see FIG. 2) that stores synchronization source data (for example, profile A, profile B, system settings, and the like) and rules for synchronization processing performed using the synchronization source data ( The information processing apparatus includes a synchronization rule storage unit 110 (refer to FIG. 2) that stores data (hereinafter referred to as synchronization rules) and executes synchronization processing according to the synchronization rules. Details of the synchronization processing and the synchronization rules will be described later.

  The scanner device 200 is an external device having a storage unit 210 (see FIG. 2) that stores synchronization destination data (for example, profile A) that is an execution target of synchronization processing of synchronization source data stored in the server device 100. .

  The load balance server apparatus 300 includes an external device having a storage unit 310 (see FIG. 2) that stores synchronization destination data (for example, system settings and the like) that is an execution target of synchronization processing of synchronization source data stored in the server apparatus 100. It is.

  The secondary server apparatus 400 includes a storage unit 410 (see FIG. 2) that stores synchronization destination data (for example, profile B, system settings, and the like) that is an execution target of synchronization processing of synchronization source data stored in the server apparatus 100. It is an external device.

  FIG. 2 is a block diagram illustrating a functional configuration of the server apparatus according to the present embodiment. The server device 100 according to the present embodiment includes a synchronization rule setting unit 101, a synchronization source data acquisition unit 102, a synchronization execution unit 103, a synchronization execution control unit 104, a synchronization rule storage unit 110, and a synchronization source data storage unit 120. Yes.

  The synchronization source data storage unit 120 stores synchronization source data such as profile A, profile B, and system settings.

  The synchronization rule storage unit 110 is synchronized with the synchronization source data stored in the synchronization source data storage unit 120 and the synchronization units stored in the storage units 210, 310, and 410 such as the scanner device 200, the load balance server device 300, and the secondary server device 400. Data of a synchronization rule that is a rule for executing a synchronization process with the previous data is stored.

  FIG. 3 is a diagram illustrating a data configuration of a synchronization rule stored in the synchronization rule storage unit of the server device according to the present embodiment. In the present embodiment, the synchronization rule data stored in the synchronization rule storage unit 110 is associated with the synchronization source data name data 301 in association with the synchronization source data name data 301, as shown in FIG. The condition data 304 is stored.

  The synchronization source data name data 301 is data of a synchronization source data name that identifies the synchronization source data stored in the synchronization source data storage unit 120.

  The synchronization destination data 302 is data of an external device that stores the synchronization source data identified by the synchronization source data name represented by the synchronization source data name data 301 and the synchronization destination data for executing the synchronization process.

  The synchronization timing data 303 is used in advance to execute a synchronization process between the synchronization source data identified by the synchronization source data name represented by the synchronization source data name data 301 and the synchronization destination data stored in the external device represented by the synchronization destination data 302. It is the data of the set timing.

  The synchronization condition data 304 can execute synchronization processing between the synchronization source data identified by the synchronization source data name represented by the synchronization source data name data 301 and the synchronization destination data stored in the external device represented by the synchronization destination data 302. Condition data.

  Returning to FIG. 2, the synchronization rule setting unit 101 stores the synchronization rule data input in accordance with the operation of the administrator of the server apparatus 100 in the synchronization rule storage unit 110, and executes the synchronization rule setting process.

  FIG. 4 is a flowchart showing the flow of the synchronization rule setting process in the server device according to this embodiment. In the present embodiment, as shown in FIG. 4, the synchronization rule setting unit 101 receives an input of a synchronization rule that is input in accordance with an operation of an administrator of the server device 100 (step S401). Next, the synchronization rule setting unit 101 stores the data of the synchronization rule that has received the input in the synchronization rule storage unit 110 (step S402).

  Returning to FIG. 2, the synchronization source data acquisition unit 102 acquires synchronization source data to be subjected to synchronization processing from the synchronization source data storage unit 120. Then, the synchronization source data acquisition unit 102 sends the acquired synchronization source data to the synchronization execution unit 103.

  The synchronization execution unit 103 functions as an execution unit that executes a synchronization process between the synchronization source data acquired by the synchronization source data acquisition unit 102 and the synchronization destination data stored in the external device.

  The synchronization execution control unit 104 functions as a control unit that prohibits execution of synchronization processing by the synchronization execution unit 103 based on at least one of the load on the external device and the load on the network 10.

  Next, the synchronization processing executed in the server apparatus 100 according to the present embodiment will be described in detail with reference to FIG. FIG. 5 is a flowchart showing a flow of execution of synchronization processing in the server device according to the present embodiment.

  The synchronization execution unit 103 refers to the synchronization timing represented by the synchronization timing data 303 stored in the synchronization rule storage unit 110, and executes a synchronization process for each external device connected via the network 10 (set in advance). And the execution of the synchronization process is started. For example, when the synchronization timing represented by the synchronization timing data 303 is “every day at 12:00” or “every 6 hours”, the synchronization execution unit 103 starts executing the synchronization processing at a preset time or every predetermined time. It can be realized by a scheduler that can. In addition, when the synchronization timing represented by the synchronization timing data 303 is a timing when the administrator performs an operation on the server apparatus 100 via the user interface such as “when the administrator logs out from the load balance server apparatus”, the synchronization execution is performed. The unit 103 starts the execution of the synchronization process with the timing when the operation on the server device 100 is performed as a trigger.

  After starting the execution of the synchronization process, the synchronization execution unit 103 first determines whether or not the synchronization source data stored in the synchronization source data storage unit 120 has been updated from the previous synchronization process to the present time (step S501). ). Specifically, the synchronization execution unit 103 corresponds to the synchronization timing data 303 that represents the synchronization timing that triggered the start of the execution of the synchronization process, among the synchronization source data name data 301 stored in the synchronization rule storage unit 110. The synchronization source data name data 301 stored together is specified. Then, the synchronization execution unit 103 determines whether or not the synchronization source data identified by the synchronization source data name represented by the identified synchronization source data name data 301 among the synchronization source data stored in the synchronization source data storage unit 120 has been updated. Determine whether. When the synchronization execution unit 103 determines that the synchronization source data stored in the synchronization source data storage unit 120 has not been updated (step S501: No), the synchronization execution unit 103 ends the execution of the synchronization process. .

  On the other hand, when it is determined that the synchronization source data stored in the synchronization source data storage unit 120 has been updated (step S501: Yes), the synchronization execution unit 103 sends the synchronization source data to the synchronization target data acquisition unit 102. Send an acquisition instruction to instruct acquisition. Here, the acquisition instruction includes, in the synchronization source data name data 301 stored in the synchronization rule storage unit 110, the synchronization source stored in association with the synchronization timing data 303 that is a trigger for starting the execution of the synchronization process. Data name data 301 is included.

  When receiving the acquisition instruction from the synchronization execution unit 103, the synchronization source data acquisition unit 102 receives from the synchronization source data storage unit 120 the synchronization source identified by the synchronization source data name represented by the synchronization source data name data 301 included in the acquisition instruction. Data is acquired (step S502). Then, the synchronization source data acquisition unit 102 sends the acquired synchronization source data to the synchronization execution unit 103.

  When the synchronization timing data 303 determines that the synchronization source data stored in the synchronization source data storage unit 120 has been updated at the synchronization timing (preset timing) (step S501: Yes), the synchronization execution control unit 104 determines whether to prohibit the execution of the synchronization process based on at least one of the load on the external device and the load on the network 10 (step S503). That is, the synchronization execution control unit 104 prohibits execution of synchronization processing at a preset timing based on at least one of whether the load on the external device is large and whether the load on the network 10 is large. It is determined whether or not. This eliminates the need for the administrator of the server apparatus 100 to instruct execution of the synchronization process, thereby reducing the burden on the administrator.

  For example, in the synchronization rule storage unit 110, the synchronization condition represented by the synchronization condition data 304 stored in association with the synchronization timing data 303 that is a trigger for starting the execution of the synchronization process is “the idle time of the secondary server device is 10 minutes. When the above is true, the synchronous execution control unit 104 calculates the idle time of the secondary server device 400 (that is, the elapsed time since the secondary server device 400 transitions to the standby state) as the load of the secondary server device 400. To do. Then, when the calculated idle time is equal to or longer than a preset time (for example, 10 minutes), the synchronization execution control unit 104 determines that the load on the secondary server device 400 that is an external device is small, and executes the synchronization process. Allow. On the other hand, if the calculated idle time is shorter than the preset time, the synchronization execution control unit 104 determines that the load on the secondary server device 400 is large and prohibits execution of the synchronization process. Thereby, it is possible to prevent the synchronization process from being executed when the load on the secondary server device 400 is large.

  In the synchronization rule storage unit 110, the synchronization condition represented by the synchronization condition data 304 stored in association with the synchronization timing data 303 that is the trigger for starting the execution of the synchronization process is “the previous network traffic is less than or equal to ○ MB”. In the case of “time”, the synchronization execution control unit 104 calculates the immediately preceding network traffic (that is, the amount of data flowing through the network 10) as the load of the network 10. Then, when the calculated network traffic is equal to or less than a predetermined threshold (for example, ◯ MB), the synchronization execution control unit 104 determines that the load on the network 10 is small and permits the execution of the synchronization process. On the other hand, when the calculated network traffic is greater than the predetermined threshold (that is, when the load on the network 10 is higher than the predetermined threshold), the synchronization execution control unit 104 determines that the load on the network 10 is large and performs the synchronization process. Prohibit execution. Thereby, it is possible to prevent the synchronization process from being executed when the load on the network 10 is large.

  In this embodiment, the example in which the prohibition of the execution of the synchronization process is determined based on the load of the external device or the load of the network 10 has been described. However, the synchronization process is determined based on the load of the external device and the load of the network 10. The prohibition of execution may be determined. For example, the synchronization execution control unit 104 prohibits the execution of the synchronization process when both the case where the idle time of the external device is shorter than a preset time and the case where the network traffic is greater than a predetermined threshold are satisfied.

  In the present embodiment, the synchronization execution control unit 104 determines whether the idle time of the secondary server apparatus 400 (an example of the load of the external device) is longer than a preset time or the load of the network 10 is a predetermined threshold value. A determination process for determining whether to prohibit the execution of the synchronization process is performed based on whether or not the synchronization process is higher, but the synchronization process is performed based on at least one of the load on the external device and the load on the network 10. Anything that prohibits execution is acceptable. For example, the synchronization execution control unit 104 continues the state where the idle time of the secondary server device 400 is a preset time or a predetermined time (for example, one minute) shorter than the preset time. In such a case, the execution of the synchronization process may be prohibited. Alternatively, the synchronization execution control unit 104 may prohibit the execution of the synchronization process when the load on the network 10 continues to be a predetermined threshold value or a value lower than the predetermined threshold value by a predetermined value. good. Alternatively, the synchronization execution control unit 104 continues the state in which the idle time of the secondary server device 400 is a preset time or a time shorter than the preset time by a predetermined time, and the load on the network 10 is a predetermined value. The execution of the synchronization process may be prohibited when the threshold value or a state that is a predetermined value lower than the predetermined threshold value continues.

  When it is determined that the execution of the synchronization process is permitted (step S503: No), the synchronization execution unit 103 stores the synchronization source data acquired by the synchronization source data acquisition unit 102 in the synchronization rule storage unit 110. The data 302 is transmitted to the external device identified by the synchronization destination represented by the synchronization destination data 302 stored in association with the synchronization timing data 303 that is the trigger for starting the execution of the synchronization processing. Thereby, the synchronization execution unit 103 executes a synchronization process between the acquired synchronization source data and the synchronization destination data stored in the external device (step S504).

  On the other hand, when it is determined that the execution of the synchronization process is prohibited (step S503: Yes), the synchronization execution unit 103 ends the execution of the synchronization process. When the execution of the synchronization process is prohibited, the synchronization execution control unit 104 causes the synchronization process to be executed between the synchronization timing at which the execution of the synchronization process is prohibited and the next synchronization timing of the synchronization timing. In other words, the synchronization execution control unit 104 causes the synchronization process to be executed when a predetermined time shorter than the synchronization timing interval elapses from a certain synchronization timing at which execution of the synchronization process is prohibited. This prevents synchronization processing from being executed until the next synchronization timing when synchronization processing is prohibited at a certain synchronization timing, and prevents the synchronization destination data stored in the external device from being stored as old data. it can.
