And device initialization order changing means 45.

  The activation method changing unit 41 analyzes log data at the time of activation of the application group 53 in the information processing apparatus 100 using the log data 56 recorded in advance, and based on the analyzed result, the application group at the time of restarting 53, the activation method is changed. Thereby, it becomes possible to automatically perform the correction process of the application starting method at the time of restarting.

  Specifically, the activation method changing unit 41 uses the log data 56 in advance to analyze the dependency of each application group 53 on a specific application such as a screen application. The activation method changing unit 41 also includes a first application group that depends on a specific application in the application group 53 and a second application group that does not depend on the specific application, based on the analysis result by the application classification unit 42. And classify. Furthermore, the activation method changing unit 41 causes the application classification unit 42 to preferentially activate the first application group over the second application group at the time of restart.

  As a result, the information processing apparatus 100 detects an application group essential for starting a specific application such as screen drawing without recognizing the design of the application and preferentially starts it, thereby shortening the apparent start time. It becomes possible.

  In addition, the activation method changing unit 41 uses the log data 56 in advance to analyze the service dependency at the time of activation between the applications in the application group 53. Based on the analysis result by the application activation order changing unit 43, the activation method changing unit 41 activates the application group 53 in order from the application that should start the service at the time of restart.

  Thereby, the information processing apparatus 100 can suppress the waiting process that occurs until the service is started without recognizing the design of the application, and can shorten the activation time.

  In addition, the activation method changing unit 41 uses the log data 56 in advance to analyze the activation processing time of each application in the application group 53. Based on the analysis result by the activation waiting time insertion unit 44, the activation method changing unit 41 sets a waiting time before activation for an application that depends on the service of an application exceeding a predetermined activation processing time set in advance at the time of rebooting. insert.

  As described above, by analyzing the application log, an appropriate waiting time until an application dependent on the service of the application exceeding the predetermined activation processing time is calculated is calculated, and the predetermined activation time at the time of restart is exceeded. Insert a wait time after starting the application. Thereby, for example, the start of the service of the application that has been performing heavy processing is accelerated, and the startup time of the entire information processing apparatus 100 is shortened.

  In addition, the activation method changing unit 41 uses the log data 56 in advance to analyze the use start order of each device group 70 used by each application of the application group 53 upon activation. The activation method changing unit 41 changes the initialization order of the device group 70 in correspondence with the activation order of the application group 53 at the time of restart based on the analysis result by the device initialization order changing unit 45.

  As a result, when the application group 53 is activated, the devices in the device group 70 are initialized in the order in which the application group 53 requests, and the device initialization timing is automatically adjusted upon restart. As described above, by initializing the earlier required devices in correspondence with the activation order of the application group 53, the activation time of the entire information processing apparatus 100 can be shortened.

<Sequence diagram of start processing of image forming apparatus>
Here, a startup sequence of the information processing apparatus 100 in the present embodiment will be described. FIG. 5 is a startup sequence diagram of the information processing apparatus according to the present embodiment.

  As shown in FIG. 5, the activation program 51 refers to the activation script 52 (S10), and when the applications are activated in the order described in the activation script 52, first, the device group 70 used by the application for operation is initialized. The device initialization program 54 is activated (S11).

  Next, the device initialization program 54 refers to the device initialization order defined in the device initialization order definition 55 (S12).

  Next, the activation program 51 activates the applications in the application group 53 in the activation order referred to in the process of S10 (S13), and the application records the activation status as log data 56 (S14).

  Next, the device initialization program 54 initializes the devices in the device group 70 in accordance with the device initialization order referred to in the processing of S12 (S15).

  The application activated in the process of S13 uses the initialized device (S16).

  Similarly, the activation program 51 activates the application of the application group 53 (S17), and the application records the activation status as the log data 56 (S18) and uses the device of the device group 70 (S19). .

  The device initialization program 54 initializes the devices in the device group 70 (S20), and the activated applications in the application group 53 record the device usage status at the time of activation as log data 56 (S21). The device of group 70 is used (S22).

  When the activation of the application included in the application group 53 is completed, the activation completion is notified to the activation program 51 (S23), and the activation program 51 activates the log analysis program 80 (S24).

  The activated log analysis program 80 analyzes the log data 56 in which the execution status at the time of activation of the above-described application is recorded (S25), changes the activation script 52 based on the analysis result (S26), and the device The initialization order definition 55 is changed (S27).

  Next, Embodiments 1 to 5 in which the information processing apparatus 100 is activated at high speed by analyzing the application log of the log data 56 described above will be described below.

<Example 1: Application classification method>
For example, the start completion timing of the information processing apparatus 100 that can be seen by the user is the image drawing completion timing. Therefore, by detecting an application (for example, “screen application”) that has issued an image drawing completion event from the log data 56 and preferentially starting an application that is essential for the image drawing completion event of the screen application in the application group 53, Reduce apparent startup time.

  Here, the application classification method according to the present embodiment will be described with reference to FIG. FIG. 6 is a diagram for explaining an application classification method according to the present embodiment. In the present embodiment, the application group 53 is classified into an application that is indispensable for the image drawing completion event of the screen application and other applications.

  For example, as illustrated in FIG. 6, the log data 56 includes “time (seconds)” from the start of activation of the activation program 51, “application name” that is the application name of the application group 53, and “application name”. "Log message" is recorded. Specifically, for example, “screen application” is recorded as “waiting for service activation of application A” “0.66712 seconds later” after the activation program 51 starts activation, and the activation status of each application is indicated. Has been.

  The activation method changing unit 41 detects the screen application that has issued the screen drawing completion event from the log data 56 in which such a log is recorded, and waits for service activation in order for the screen application to issue the screen drawing completion event. Analyze the service startup wait relationship between the applications that become.

  For example, the log data 56 includes “screen application” log message “waiting for application A service activation”, and “app A” log message “waiting for application C activation” and “waiting for application B activation”. It is recorded.

  Therefore, from these log data, the activation method changing unit 41 uses the application classification unit 42 to display the screen application dependent group required for the screen application 53A to issue the screen drawing completion event as shown in FIG. The applications “application A, application B, application C” belonging to 53B and the application “application D, application E, application belonging to the screen application independent group 53C that are not required for the screen application 53A to issue a screen drawing completion event” F ”.

<Application classification process sequence diagram>
FIG. 7 is a sequence diagram of application classification processing according to the present embodiment. As described above, the activation method changing unit 41 changes the activation script 10 based on the results of the screen application dependent group 53B and the screen application independent group 53C classified by the application classification unit 42. Specifically, the description order of the start script 10 is described in the order of the screen application dependent group 53B, the screen application 53A, and the screen application independent group 53C.

  When the information processing apparatus 100 is activated in this state, as illustrated in FIG. 7, the activation program 51 reads and activates applications belonging to the screen application dependent group 53B (S30).

  When the activation program 51 is activated, the applications belonging to the screen application dependent group 53B perform initialization processing such as detection of various data used by the application, HDD partition check of the device group 70 to be used, and connection processing between applications. Perform (S31). Next, when the activation program 51 reads and activates the screen application 53A (S32), the screen application 53A performs the above-described initialization process (S33). (S34).

  Upon receiving a screen drawing completion notification from the screen application 53A, the activation program 51 reads and activates an application belonging to the screen application independent group 53C (S35), and the application belonging to the screen independent group 53C performs the initialization process described above. (S36).

  As described above, the application of the screen application dependent group 53B and the screen application 53A are preferentially executed until a screen drawing completion event is issued. As a result, the processing necessary for completing the screen drawing is executed without being hindered by the execution of the screen application-independent group 53C, thereby shortening the startup time of the information processing apparatus 100.

<Example 2: Method for changing application startup order>
Next, the activation order changing method according to the present embodiment will be described with reference to FIG. FIG. 8 is a diagram for explaining the activation order changing method according to the present embodiment.

  As described above, since the activation program 51 activates the applications in the order described in the activation script 52, when there is a master-slave relationship between the applications, a service activation wait occurs, and the activation time accordingly. It will be late.

  As shown in FIG. 8, for example, “1: App A is read, 2: App A is executed, 3: App B is read, 4: App B is executed, 4: App C is read, 5: App C is read. , 6: Execute application C "will be described in the order of application names.

  As described in the activation script 52 as described above, for example, as recorded in the log data 56-1 shown in FIG. 8, the application A is “waiting for service activation of the application C” and “waiting for service activation of the application B”. ”, The application B is“ waiting for the service activation of the application C ”, the service of the application C is activated, the service of the application B is activated, and the service of the application B is activated. It is activated.

  Therefore, in order to start the information processing apparatus 100 and execute the application A, a service start waiting for other applications such as waiting for the start of services of the application B and the application C occurs.

  As an example of the service described above, there is a client-server relationship by IPC (interprocessor communication), for example.

  Therefore, when the startup of the information processing apparatus 100 in the initial installation state is completed, the log analysis program 80 is started in advance, and the startup method changing unit 41 analyzes an application with a high degree of service dependence from the log data 56.

  In the example of FIG. 8, since application A and application B are waiting for service activation of application C, application C becomes the application with the highest degree of service dependence, and application A waits for service activation of application B. Therefore, the application B can be analyzed as the application having the next highest degree of service dependency.

  The activation method changing unit 41 rewrites the activation order of the activation script 52 in order from the application having a high degree of service dependency by the application order changing unit 43 using the analysis result.

  For example, as illustrated in FIG. 8, the application order changing unit 43 uses the analyzed result to read “1: application C”, 2: execute application C, 3: read application B, into the startup script 52-2. "4: Execute application B, 5: Read application A, 6: Execute application A" and the application startup sequence.

  When the information processing apparatus 100 is restarted in this state, for example, as recorded in the log data 56-2 shown in FIG. 8, after the application C is started, the application B is started and the service of the application C is started. After the start of use, the application B service can be activated. Further, the application A can start the service of the application A after the service of the application C and the service of the application B start to be used.

  As a result, when each application is activated, the service activation waiting for other applications does not occur, so the activation time of the information processing apparatus 100 is shortened.

<Sequence diagram before starting sequence change>
Here, with reference to FIG. 9, the sequence before the activation order change shown in FIG. 8 will be described. FIG. 9 is a sequence diagram before the activation order is changed according to the present embodiment.

  As illustrated in FIG. 9, the activation program 51 reads the application A in the order of description of the activation script 52-1 in FIG. 8 (S <b> 40) and activates the application A (S <b> 41). A wait occurs (S42). Next, the activation program 51 reads the application B (S43), and when the application B is activated (S44), the application B waits for service activation of the application C (S45).

  Next, the activation program 51 reads the application C (S46), activates the application C (S47), activates the service of the application C for the application A (S48), and activates the service of the application C for the application B. Is activated (S49).

  Next, application A waits for service activation of application B in application A (S50), and when the service of application B is activated for application A (S51), application A activates the service (S52).

  As described above, after application A starts, application A and application B wait for service activation of application C, and application A waits for service activation of application B, and application C and application B The application A is activated after the service is activated.

<Sequence diagram after starting sequence change>
Next, the sequence after changing the activation order shown in FIG. 8 will be described with reference to FIG. FIG. 10 is a sequence diagram after changing the activation order according to the present embodiment.

  As shown in FIG. 10, the activation program 51 reads the application C in the order of description of the activation script 52-2 in FIG. 8 (S60), and when the application C is activated (S61), the application C activates the service (S62). ).

  Next, the activation program 51 reads the application B (S63), and when the application B is activated (S64). Since the service of the application C has already been activated in the process of S62, Is used (S65).

  Next, the activation program 51 reads the application A (S66). When the service is activated in the application B (S67) and the application A is activated (S68), the application A starts using the service of the application C (S69), and then the service of the application B is started (S70). ), The service of the application A is activated (S71).

  As described above, before the application A starts using the service, the services of other applications such as the application B and the application C that the application A uses the service have been activated. As described above, since the application is started in order from the application that should start the service early, the apparatus does not recognize the design of the application, suppresses the start waiting state of the service between the applications, and starts the information processing apparatus 100. Reduce time.

<Example 3: Startup waiting time insertion method>
Next, the activation waiting time insertion method according to the present embodiment will be described with reference to FIG. FIG. 11 is a diagram for explaining the activation waiting time insertion method according to the present embodiment.

  By changing the application activation order as described above, it is possible to suppress the occurrence of service activation waiting and eliminate the delay in activation time associated with service activation waiting. However, when heavy processing is executed before the service is started, there is a case where waiting for the start of the service of another application occurs.

  As shown in FIG. 11, the application activation order is changed in the above-described service dependency order, and “1: application C is read, 2: application C is executed, 2: application B is read, and application B is read. “4: execute application B, 5: read application A, 6: execute application A”.

  Even if it is described in the startup script 52-3 in this way, for example, as recorded in the log data 56-3 shown in FIG. After that, the application C is “service activation”.

  As described above, when the application B is executed, the service activation waiting for the application C, which is another application, is generated.

  This is because, as described above, when the app C performs heavy processing before the service is started, the start of the app B that uses the service of the app C is started earlier.

  Therefore, when startup of the information processing apparatus 100 in the initial installation state is completed, the log analysis program 80 is started, and the startup method changing unit 41 executes heavy processing exceeding a predetermined startup processing time from the log data 56. An appropriate wait time (start-up waiting time) is calculated by detecting a presumed application and analyzing the log data 56.

  Using the analysis result, the activation method changing unit 41 uses the calculation result described above immediately after the execution statement of the application that is presumed to have executed a heavy process in the activation script 52 by the activation waiting time inserting unit 44. Insert a wait instruction of an appropriate length based on.

  For example, as illustrated in FIG. 11, the activation waiting time insertion unit 44 uses the analyzed result to read “1: application C is read, 2: application C is executed, 3: wait, 4: “Read application B, 5: execute application B, 6: read application A, 7: execute application A” and insert a wait instruction having an appropriate length.

  When the information processing apparatus 100 is restarted in this state, for example, as recorded in the log data 56-4 illustrated in FIG. 11, after the application C is started, after waiting for heavy processing to be completed, The activation program 51 activates the application B that depends on the service of the application C.

  As a result, execution of heavy processing is preferentially executed without being interrupted by other applications, thereby accelerating completion of execution of heavy processing and without waiting for service activation. Startup time is reduced.

<Sequence diagram before insertion waiting time>
Here, with reference to FIG. 12, the sequence before the insertion waiting time shown in FIG. 11 will be described. FIG. 12 is a sequence diagram before the activation waiting time is inserted according to the present embodiment.

  As shown in FIG. 12, the activation program 51 reads the application C in the order of description of the activation script 52-3 in FIG. 11 (S80), and when the application C is activated (S81), heavy processing is executed in the application C. (S82).

  Next, the activation program 51 reads the application B (S83), and when the application B is activated (S84), the application B waits for the service activation of the application C (S85).

Next, the activation program 51 reads the application A. (S86)
Next, the service of the application C is activated for the application B (S87), and the service is activated in the application B (S88).

  Next, the activation program 51 activates the application A (S89), the application A starts using the service of the application C (S90), and then the application B starts using the service (S91). The service of A is activated (S92).

<Sequence diagram after insertion of startup wait time>
Next, the sequence after the activation waiting time insertion shown in FIG. 11 will be described with reference to FIG. FIG. 13 is a sequence diagram after insertion of the activation waiting time according to the present embodiment.

  As shown in FIG. 13, the activation program 51 reads the application C in the order of description of the activation script 52-4 in FIG. 11 (S100), and when the application C is activated (S101), heavy processing is executed in the application C ( S102).

  Next, in the activation program 51, a waiting time is added based on the wait of the activation script 52-4 inserted by the activation waiting time insertion means 44 (S103), and when the application B is read after the waiting time of S103 ( S104) A service is activated in application C (S105).

  Next, when the activation program 51 activates the application B (S106), since the service of the application C has already been activated in the process of S105, the application B does not wait for the activation of the application C without waiting for the activation of the application C. Use of the service is started (S107).

  Next, the activation program 51 reads the application A (S108). A service is activated in the application B (S109).

  Next, the activation program 51 activates the application A (S110), the application A starts using the service of the application C (S111), and then the application B starts using the service (S112). The service of A is activated (S113).

  As described above, since the activation waiting time is inserted before the application B is read, the heavy processing of the application C is preferentially executed without the application B interrupting the execution of the heavy processing of the application C. This speeds up the completion of the heavy processing of application C. As a result, the start of the service of the application C is accelerated, and the start time of the service of the application C in the application B is suppressed, thereby shortening the startup time of the information processing apparatus 100 as a whole.

<Example 4: Method for changing device initialization order>
Next, a device initialization order changing method according to the present embodiment will be described with reference to FIG. FIG. 14 is a diagram for explaining a device initialization order changing method according to the present embodiment.

  As described above with reference to FIG. 4, the application group 53 operates using a device group 70 such as an HDD or a USB memory disk. The device group 70 becomes usable by an application only when the device initialization program 54 performs initialization processing in accordance with the device initialization order defined in the device initialization order definition 55.

  However, when the initialization of the device group 70 is described in the device initialization order definition 55 in the device position order, there is a case where a device use start waiting occurs.

  As shown in FIG. 14, for example, in the device initialization order definition 55-1, "1: Device A initialization, 2: Device B initialization, 3: Device C initialization, 4: Device D initialization" The case where they are described in the order of position will be described.

  In this way, when described in the device initialization order definition 55-1, for example, as recorded in the log data 56-5 shown in FIG. 14, devices A to D are initialized in order. On the other hand, the application C that is activated first “uses device B” and then “uses device D”.

  Therefore, for example, when the device B is not initialized before the app C starts using the device B, the app C has to wait for the device B to be initialized, and the app C uses the device B. A device use start waiting state occurs.

  Therefore, when the startup of the information processing apparatus 100 in the initial installation state is completed, the log analysis program 80 is started, and the startup method changing unit 41 analyzes the device use start event appearing in the log data 56. For example, in the example of FIG. 14, since the log data 56 includes “start use of device B” and “start use of device D”, the use start event of the device is device B, device D, device A,. Can be analyzed.

  The activation method changing means 41 rewrites the activation order of the device initialization order definition 55 in the order of the device use start event by the device initialization order changing means 45 using the analysis result.

  For example, as shown in FIG. 14, the device initialization order changing unit 45 uses the analysis result to set “1: Device B initialization”, 2: Device D initialization, 3: The device A initialization, 4: device C initialization, and the device group 70 initialization sequence are described.

  When the information processing apparatus 100 is restarted in this state, for example, as recorded in the log data 56-6 illustrated in FIG. 14, for example, the device B is first initialized, and then the application C starts using the device B. Then, when the device D is initialized and the application C starts using the device D, the time until the application C activates the service is shortened.

  In this way, device initialization is performed in the order required by the application group, and the time required to wait for the start of use of the device is shortened. Therefore, the startup time of the information processing apparatus 100 is shortened.

<Sequence diagram before changing device initialization order>
Here, the sequence before the device initialization order change shown in FIG. 14 will be described with reference to FIG. FIG. 15 is a sequence diagram before changing the device initialization order according to the present embodiment.

  As shown in FIG. 15, the activation program 51 first activates the initialization program 54 (S120). Next, according to the description order of the startup script 52, for example, when the application C is started (S121), the application C tries to start using the device B (S122), but the device B is not initialized. As indicated by the arrow A of 15, the application C enters a use start waiting state for the device B.

  Next, the device initialization program 54 first initializes the device A according to the device initialization order definition 55-1 (S123), and then initializes the device B (S124). Here, the use start completion is notified from the device B to the app C (S125), and the app C starts using the device B for the first time.

  Next, the application C tries to start using the device D (S126). However, since the device D has not been initialized, for example, as shown by an arrow B in FIG. It becomes.

  Next, the device initialization program 54 initializes the device C (S127), and initializes the device D (S128). Here, the start of use is notified from the device D to the app C (S129), the app C starts using the device D for the first time, and the app C activates the service (S130).

  Next, the activation program 51 activates the application B (S131), starts using the service of the application C in the application B (S132), and the application B activates the service (S133). Next, the activation program 51 activates the application A (S134), starts using the service of the application C in the application A (S135), starts using the service of the application B (S136), and starts using the device A. An attempt is made (S137). When the device A is notified of the completion of use to the app A (S138), the app A starts using the device A, and the app A activates the service (S139).

<Sequence diagram after changing device initialization order>
Next, the sequence after the device initialization order change shown in FIG. 14 will be described with reference to FIG. FIG. 16 is a sequence diagram after changing the device initialization order according to the present embodiment.

  As shown in FIG. 16, the activation program 51 activates the device initialization program 54 (S140), and activates the application C (S141).

  The application C tries to start using the device B (S142), and the application C enters the use start waiting state for the device B as indicated by an arrow C in FIG. 16, but the device initialization program 54 initializes from the device B. For this reason (S143), the device B is notified of the completion of the use start to the application C (S144), and the application C immediately starts using the device B. As a result, the time taken to wait for the start of use of the device is shortened compared to the case shown in FIG.

  Similarly, the application C tries to start using the device D (S145), and the application C enters the use start waiting state for the device D as indicated by an arrow D in FIG. In order to initialize D (S146), the device D is notified of completion of use to the app C (S147), and the app C immediately starts using the device D, and the app C activates the service ( S148).

  In this way, the time required to wait for the start of use of the device is shortened compared to the case shown in FIG. In addition, as described above, the time required for the application C to wait for the start of use of the devices B and D is shortened, so that the time until service activation is further shortened.

  Therefore, next, when the activation program 51 activates the application B (S149), since the application B can immediately start using the service of the application C (S150), the service of the application B is activated (S151). Will also be faster.

  Next, the device initialization program 54 initializes the device A (S152), the activation program 51 activates the app A (S153), and the app A starts using the service of the app C (S154). The service use of B is started (S155). Further, the app A tries to start using the device A (S156), and when the use start completion is notified from the device A (S157), the app A activates the service (S158). Next, the device initialization program 54 initializes the device C (S159).

  As described above, by initializing the device group 70 in the order that the application group 53 requires devices, the time required for the application to start using the device to start using the device can be shortened. The startup time of the entire 100 is shortened.

<Example 5: Application configuration change processing>
Next, application configuration change processing according to the present embodiment will be described with reference to FIG. FIG. 17 is a flowchart showing a flow of application configuration change processing according to the present embodiment.

  The optimization of the activation method shown in the first to fourth embodiments described above is based on the premise that the configuration of applications installed in the information processing apparatus 100 does not change.

  Therefore, for example, when the application configuration of the information processing apparatus 100 is changed by installing or uninstalling the application in the information processing apparatus 100, the above-described dependency between the applications is changed, and the device use start timing is also changed. .

  Therefore, the activation method changing unit 41 executes an application configuration changing process as follows.

  As shown in FIG. 17, in the first activation step, the activation method changing unit 41 classifies the application group 53 using the application classification unit 42 by the application classification process of the first embodiment described above, and creates the activation script 52. Change (S160). As a result, the application group 53 is classified into the above-described applications that are essential for activation and the applications that are not essential for activation.

  Next, the activation method changing unit 41 confirms whether or not the application has been changed by installation or uninstallation (S161). If it is determined that there is no change (NO in S161), the activation method changing unit 41 restarts. If it is determined that there has been a change (YES in S161), the process returns to S160.

  Next, in the second startup step, the startup method changing unit 41 changes the application startup order of the application group 53 using the application order changing unit 43 by the application order changing process of the second embodiment described above, and starts the startup script. 52 is changed (S162). As a result, the application activation order can be determined and the adjustment process based on the third and fourth embodiments described above can be validated.

  Next, the activation method changing unit 41 confirms whether or not the application has been changed by installation or uninstallation (S163). If it is determined that there is no change (NO in S163), the activation method changing unit 41 restarts. If it is determined that there has been a change (YES in S163), the process returns to S160.

  Next, in the third activation step, the activation method changing unit 41 changes the device activation order of the device group 70 using the device initialization order changing unit 45 by the device initialization order changing process of the fourth embodiment described above. Then, the device initialization order definition 55 is changed (S164).

  As a result, the device initialization order corresponding to the application startup order determined in the process of S162 is determined. If the application activation order is determined, the device initialization order will not be changed thereafter.

  Next, the activation method changing unit 41 confirms whether or not the application has been changed by installation or uninstallation (S165). If it is determined that there is no change (NO in S165), the activation method changing unit 41 restarts. If it is determined that there has been a change (YES in S165), the process returns to S160.

  Next, in the fourth activation step, the activation method changing unit 41 predicts the processing time of the application as needed from the service activation timing, and performs the activation waiting time insertion unit 44 by the activation waiting time insertion process of the third embodiment described above. Is used to insert an appropriate activation waiting time into the activation script 52 (S167).

  Next, the activation method changing unit 41 confirms whether or not the application has been changed by installation or uninstallation (S168). If it is determined that there is no change (NO in S168), the activation method changing unit 41 restarts. If it is determined that there has been a change (YES in S168), the process returns to S160.

  As described above, every time the information processing apparatus 100 in the initial installation state is activated, the activation method is changed by the activation method changing unit 41, and the configuration of the application is changed by installation, uninstallation, or the like. In this case, since the service dependency relationship between applications may be changed, optimization of the activation method is performed again from the first step.

  As a result, even when the information processing apparatus 100 has an application configuration that is not assumed at the time of product shipment, for example, it is possible to obtain an optimal startup time corresponding to the application configuration change. It is possible to always minimize the activation time of 100.

  In addition, although Example 1-Example 5 mentioned above demonstrated the execution process at the time of restart, in this invention, it is not limited to this, For example, after shutting down information processing apparatus 100, when starting next Also, the same execution process as that at the time of restart is applied.

  As described above, according to the present embodiment, by analyzing the application log data, the startup method is automatically adjusted to enable high-speed startup of the information processing apparatus corresponding to the configuration of the application, and the configuration of the application The startup time of the information processing apparatus is optimized in response to the change.

The invention made by the present inventor has been specifically described based on the preferred embodiments. However, the present invention is not limited to that described in the above embodiments, and various modifications can be made without departing from the scope of the invention. Is possible.
