Because user systems have numerous combinations of configurations due to differences in hardware and software such as operational applications, a vast amount of equipment and labor is required on the vendor side to measure the application time for each user system. Will accompany. For this reason, when the specification is such that the application tool can be applied to all user systems, it is not realistic for the vendor to provide the application time of the batch correction data to the individual user systems. In this case, the prediction of the application time is often left to individual customers, and the customer predicts the application time of the own user system based on experience or the like.

However, it is difficult to accurately estimate the application time. In addition, the application tool often does not stop (cannot be stopped midway) unless it is applied to the user system once the batch correction data (all patches corresponding to the user system) is applied. Therefore, when safety is prioritized, there is a problem that the operation efficiency of the user system is reduced because the application time is estimated to be long and the maintenance time is long.

Note that the above-described problem is not considered in the related technology described above.
In one aspect, an object of the present invention is to easily predict an application time of update information according to an information processing apparatus.
In addition, the present invention is not limited to the above-described object, and other effects of the present invention can be achieved by the functions and effects derived from the respective configurations shown in the embodiments for carrying out the invention which will be described later. It can be positioned as one of

The correction information application program of this case is a computer that executes a predetermined process, and applies the update information while the predetermined process is stopped to update the own computer while the predetermined process is being executed.

Hereinafter, embodiments will be described with reference to the drawings.
[1] One Embodiment [1-1] Configuration of Information Processing System A configuration of an information processing system 1 as an example of one embodiment will be described below with reference to FIG.

FIG. 1 is a diagram illustrating a configuration example of an information processing system 1 according to an embodiment.
As shown in FIG. 1, an information processing system 1 according to an embodiment includes n (n is an integer of 1 or more) user systems 2-1 to 2-n (hereinafter referred to as user systems 2-1 to 2-n). Are not referred to simply as a user system 2) and a standard system 3.
The information processing system 1 provides a service for distributing a set (update information 4, hereinafter referred to as correction data 4) of patches (unit update information) 4a such as OS correction programs to one or more user systems 2. To do. The patch 4a refers to an individual correction program that is used for updating the user system 2 individually.

It should be noted that the patch 4a may be a modification program for various systems such as a core system or an application in addition to an OS modification program. Since the correction data 4 is likely to affect various applications in the user system 2 by application, the user system 2 does not apply the correction data 4 during the business operation of the user system 2 and stops the business. After that, the correction data 4 is applied within the maintenance time (during stoppage).

An information processing system 1 according to an embodiment includes a correction data application program including correction data 4 for one or more user systems 2 and a program for applying the correction data 4 to individual user systems 2. Distribute The correction data application program is distributed to all user systems 2 to which the correction data 4 is applied.
The user system 2 is a system used by a customer, and executes, for example, a Web service, a database service, and other various tasks (predetermined processing). An example of the user system 2 is an information processing apparatus such as a server or a personal computer (PC).

In addition, the user system 2 updates the own user system 2 by applying the correction data 4 during the maintenance time, that is, during the stoppage of the work, by the customer or the administrator using the correction data application program. By applying the correction data 4, the user system 2 corrects a program such as an OS and adds a function.
By the way, since the application time of the correction data 4 is different for each user system 2 as described above, a provider such as a vendor that provides the correction data 4 to the user system 2 responds to the user system 2 to the customer. Providing application time is not practical.

Therefore, the correction data application program according to an embodiment includes a function for causing each user system 2 to predict (acquire) the application time of the correction data 4.
For example, the information processing system 1 includes a standard system 3 that measures in advance a reference application time that is a reference for predicting the application time of the correction data 4 in the user system 2.
The standard system (other information processing apparatus) 3 is an information processing apparatus such as a server or a PC. It is preferable that the standard system 3 includes at least components that are shared by at least one user system 2 to which the correction data 4 is applied. For example, the standard system 3 includes a central processing unit (CPU), a memory, a storage unit such as a hard disk drive (HDD), a compact disk (CD) drive, and the like. Note that the hardware performance of the components provided in the standard system 3 may not be equivalent to that of the user system 2.

The standard system 3 applies the same correction data 4 (one or more patches 4a) and dummy patches 4b as those applied to the user system 2, and measures the application time (reference application time) required for each application. Then, the patch application information 4c is generated.
Here, the dummy patch (pseudo update information) 4b is a patch applied to both the user system 2 and the standard system 3 in one embodiment. Unlike the patch 4a, the dummy patch 4b is a patch that does not affect the system such as the OS of the user system 2 and the standard system 3 or has a small effect. For example, the dummy patch 4b may be a patch that does not change the settings of an existing system, such as a dummy program that performs a process of copying an empty file (dummy data) to an empty storage area of the user system 2 or the standard system 3. it can.

The standard system 3 measures the reference application time (first reference application time) by applying the dummy patch 4b in advance with no load (less). The standard system 3 measures the reference application time (second reference application time) by applying one or more patches 4a (correction data 4) in advance in the absence of a load. Then, patch application information 4c including these measurement results is generated.
The no load state refers to resources used to maintain the operation of the system and other minimum resources such as a stop state in which the load processing corresponding to the work in the user system 2 is stopped. The idle state used. For example, in a state where there is no load, the CPU usage rate is preferably less than a certain value such as several percent. The same applies to the user system 2.

Then, the information processing system 1 creates a correction data application program including the correction data 4 and the dummy patch 4b and the patch application information 4c generated by the standard system 3, and distributes it to the user system 2. The creation of the correction data application program may be performed by the standard system 3 or may be performed by another device. Further, the correction data application program may be recorded on a recording medium such as an optical disk such as a CD or a flash memory in the standard system 3 or another apparatus, and the recording medium may be distributed to customers.

When the user system 2 receives the correction data application program, the user system 2 executes the program included in the correction data application program and performs the following processes (i) to (iii).
(I) During business operation (during execution of predetermined processing), the dummy patch 4b is applied to the user system 2, and the application time (pseudo update information application time) of the dummy patch 4b is measured.
(Ii) Based on the measured application time of the dummy patch 4b, an estimated value (estimated application time) when the dummy patch 4b is applied to the user system 2 while the work is stopped is estimated.

(Iii) On the basis of the estimated value estimated and the reference application time (first and second reference application times) obtained in advance by the standard system 3 included in the patch application information 4c, the correction data 4 during the operation stoppage Is applied to the user system 2 to predict (acquire) the application time.
FIG. 2 is a diagram for explaining an example of a procedure for acquiring the application time of the correction data 4 in the user system 2 shown in FIG.

As shown in FIG. 2, the user system 2 wants to acquire correction data 4 (one or more patches 4a) in the user system 2 while the business is stopped (during maintenance time), that is, there is no business load (small) ) Is the application time.
As described above, in the correction data application program, the standard system 3 is measured in a stopped state (no load (small) state) in which the load processing corresponding to the work in the user system 2 is stopped. The reference application times of both the dummy patch 4b and the correction data 4 are included (see the upper column in FIG. 2).

The user system 2 applies the dummy patch 4b and measures the application time of the dummy patch 4b in the above (i) during business operation, that is, with a business load (see the left column in the middle column of FIG. 2). . As described above, since the dummy patch 4b has no effect (small) on the OS such as the OS of the user system 2, the user system 2 can apply the dummy patch 4b even during business operation. it can.

However, the application time acquired in (i) above is measured during business operation, and is measured in an environment different from the environment during business suspension where the correction data 4 is actually applied. Therefore, in the above (ii), the user system 2 estimates the estimated value of the application time when the dummy patch 4b is applied while the work is stopped, based on the result of the application time acquired in (i) above. (Refer to the lower left of FIG. 2)

As a result, the application time of the dummy patch 4b and the correction data 4 in the standard system 3 with no load and the application time of the dummy patch 4b in the user system 2 with no load are obtained.
Then, the user system 2 can predict (convert) the application time when the correction data 4 is applied during the operation stop from the application time in the above-described (iii) based on the ratio relationship (FIG. 2). (See right below), providing customers with predicted application times.

As described above, conventionally, it is difficult for each user system unit to provide the application time of the correction data to the customer, and the prediction of the application time is left to the individual customer. On the other hand, according to the information processing system 1 according to the embodiment, the application time in each user system 2 can be predicted.
Therefore, since the user system 2 can provide the customer with the application time of the correction data 4 in advance and accurately before the application of the correction data 4 to the user system 2, the customer can minimize the maintenance time. Can be estimated, and the operational efficiency of the user system 2 can be improved.

Hereinafter, a detailed configuration of the information processing system 1 as described above will be described.
[1-2] Hardware Configuration of User System and Standard System Next, the hardware configuration of the user system 2 and the standard system 3 will be described with reference to FIG.

The input / output units 20e and 30e include at least one of an input device such as a mouse and a keyboard and an output device such as a display and a printer. The input / output units 20e and 30e receive operation commands by the operations of the operator (administrator) and the customer (user) of the user system 2 and the standard system 3 by the input device, and the application time by the user system 2 and the standard system 3 The measurement results such as are displayed (output) on the output device.

The recording media 20f and 30f are storage devices such as a flash memory and a ROM, and record various data and programs. The reading units 20g and 30g are devices that read data and programs recorded on computer- readable recording media 20h and 30h such as an optical disk and a universal serial bus (USB) memory.

And run. Thereby, the computer as the user system 2 and the computer as the standard system 3 realize the functions of the user system 2 and the standard system 3 according to the present embodiment by the CPUs 20a and 30a.

The blocks 20a to 20g and the blocks 30a to 30g are connected to each other via a bus so as to communicate with each other.
The above-described hardware configuration of the information processing system 1 is an example. Therefore, the increase / decrease or division of the hardware in the individual user system 2 or the standard system 3, integration in an arbitrary combination, and the like may be performed as appropriate.

[1-3] Functional Configuration of User System Next, a functional configuration of the user system 2 will be described with reference to FIG. FIG. 4 is a diagram illustrating a functional configuration example of the user system 2 illustrated in FIG. 1.
FIG. 4 shows a functional configuration example of the user system 2 realized by the CPU 20a developing and executing the correction data application program in the memory 20g. For example, the correction data application program is read from the recording medium 20h by the reading unit 20g shown in FIG.

As shown in FIG. 4, the user system 2 includes a holding unit 21, a management unit 22, and an application processing unit 23. The holding unit 21 is realized by the memory 20b or the storage unit 20c shown in FIG. 3, and the management unit 22 and the application processing unit 23 are realized by the CPU 20a.
The holding unit 21 holds correction data 4, including one or more (a plurality in the example illustrated in FIG. 4) patches 4a, one dummy patch 4b, and patch application information 4c.

FIG. 5 is a diagram illustrating an example of the patch application information 4c illustrated in FIG. 4, and FIG. 6 is a diagram illustrating the contents of the modification data 4 application processing by the user system 2 illustrated in FIG.
As shown in FIG. 5, the patch application information 4c is a database including patch IDs, reference application times of all patches 4a and dummy patches 4b, and priorities, and can be in a table format, for example.

The patch ID is an example of information for identifying each patch 4a and dummy patch 4b, and indicates a 6-digit character string that identifies the type of the patch 4a and dummy patch 4b, and the version number of the patch 4a and dummy patch 4b. 2 character string. For example, the patch ID “145678-09” is the ninth version of the patch 4a of the type identified by “145678”.
Each reference application time is a measurement value measured in advance in the standard system 3 without any load.

Here, the application process of the patch 4a and the dummy patch 4b in the user system 2 and the standard system 3 includes five processes (internal processes) A process to E process as shown in FIG. For example, as shown in FIG. 5, each reference application time includes processing times (seconds) of a plurality of processes A to E for each patch 4a and dummy patch 4b.
As shown in the upper part of FIG. 6, in the A process, the CD drives (reading units) 20g and 30g read the patch data of the compressed patch 4a recorded on the CDs (recording media) 20h and 30h, and the memory 20b , 30b and storage units 20c, 30c, etc., are temporarily stored in a storage area (for example, “/ tmp”). The B process is a process in which the CPUs 20a and 30a expand (decompress) the compressed patch data. The C process writes the expanded patch data to the HDDs (storage units) 20c and 30c. It is processing. Further, the D process is a process in which the CPUs 20a and 30a analyze the data written to the HDDs 20c and 30c, and the E process is a process for analyzing the patch data analyzed by the CPUs 20a and 30a in an appropriate storage area in the HDDs 20c and 30c. Is a process of applying the patch 4a.

In the patch application information 4c, the standard system 3 measures and sets the processing times of the A process to the E process for all the patches 4a and the dummy patches 4b.
The priority is information defining the priority of each of the plurality of patches 4a, and is set in consideration of the order of application to the user system 2 for each patch 4a.
Hereinafter, the information for one line specified by the patch ID in the patch application information 4c is referred to as patch information.

The management unit 22 executes the processes (i) to (iii) for predicting the application time when the correction data 4 is applied to the user system 2 during the business operation, and the user system 2 The patch 4a to be actually applied is determined. Therefore, the management unit 22 includes an environment correction value calculation unit 22a, a target patch identification unit 22b, and an application time calculation unit 22c.
In the user system 2, the environment correction value calculation unit 22a measures the application time by applying the dummy patch 4b provided by the provider during business operation in order to predict the application time of the correction data 4 in advance. Then, the environmental correction value calculation unit 22a compares the measured application time with the application time in the standard system 3 using the same dummy patch 4b, so that the difference in the hardware configuration between the standard system 3 and the user system 2 is obtained. Is factorized.

However, as shown in FIG. 2, if the application time of the dummy patch 4b is not measured in an environment where work is stopped in the user system 2, the application environment of the actual correction data 4 provided by the provider ( It cannot be said that the application time is in line with (no load).
Therefore, the environment correction value calculation unit 22a converts the measured application time of the dummy patch 4b into a value measured by the user system 2 in the business stoppage.

Hereinafter, specific functions of the environment correction value calculation unit 22a will be described.
The environment correction value calculation unit (measurement unit) 22a repeatedly performs the application process of the dummy patch 4b a plurality of times (for example, 24 hours at 30-minute intervals) in the user system 2 in business operation. The processing time of the process is measured, and the application time of each dummy patch 4b is acquired. At this time, the environment correction value calculation unit 22a estimates the CPU usage rate shown in FIGS. 7 and 8 in order to estimate an estimated value when measured by the user system 2 that is in a suspended state from the application time of the acquired dummy patch 4b. And the cue value are measured together with the application time.

FIGS. 7 and 8 show examples of the CPU utilization rate and processing time measurement results, and the queue value and processing time measurement results when the dummy patch 4b is applied by the environment correction value calculation unit 22a shown in FIG. FIG. 7A and FIG. 8A are diagrams showing measurement result tables, and FIG. 7B and FIG. 8B are scatter diagrams showing measurement results. . In the following description, FIG. 7 will be described as an example of the measurement result of the B process, and FIG. 8 will be described as an example of the measurement result of the C process.

Here, the processing speed (capacity) of the CD drives 20g and 30g is much slower (lower) than the processing speed (capacity) of the CPUs 20a and 30a and the HDDs 20c and 30c. In the processing of the CD drives 20g and 30g, no interruption from business processing is entered. Therefore, the processing time of the A process does not depend on the business operation state (load state) but depends on the processing capacity of the CD drive, that is, the hardware performance (see the lower part of FIG. 6).

On the other hand, the B process to the E process are operated mainly by the CPUs 20a and 30a and the HDDs 20c and 30c, and thus are affected by a load during business operation. That is, the processing time of the B process to the E process depends on both the hardware performance and the business operation state (load state) (see the lower part of FIG. 6).
Therefore, the environment correction value calculation unit 22a measures only the processing time for the reading process (A process) of the CD drive 20g. On the other hand, for the CPU processing (B processing, D processing), the environment correction value calculation unit 22a measures the CPU usage rate and processing time as shown in FIG. 7A, and writes the HDD writing processing (C processing, E processing). For processing, as shown in FIG. 8A, the queue value and processing time are measured. The queue value is a numerical value of the processing waiting state of the HDD 20c, and is information indicating the number of queued on the system side, for example, the number of files.

Thus, the environmental correction value calculation unit 22a is an example of a measurement unit that measures a plurality of processing times and loads by applying the dummy patch 4b to the user system 2 during business operation.
In addition, the environment correction value calculation unit 22a replaces the processing times of the processing A to E of the application processing of the dummy patch 4b measured during the business operation with the estimated application time when the business is stopped.
Specifically, the environment correction value calculation unit 22a calculates a simple average value of the processing time (actually measured value) for the A process. In addition, as shown in FIGS. 7B and 8B, the environment correction value calculation unit 22a creates a scatter diagram with each actual measurement value for B processing to E processing, and performs B regression by single regression analysis. The process and the D process calculate an estimated value with a CPU usage rate of 0%, and the process C and the E process calculate an estimated value with a queue value of 0. For example, by simple regression analysis, “0.14 (seconds)” is obtained as an estimated value for B processing as shown in FIG. 7B, and “C4 processing estimated value as shown in FIG. 2.3 (seconds) "is obtained.

The environment correction value calculation unit 22a uses the simple average value of the A process and the estimated values of the B process to the E process calculated as described above as an estimated value (estimated application) obtained by applying the dummy patch 4b in the user system 2 while the work is stopped. Time).
In other words, the environment correction value calculation unit 22a removes the load due to the business operation by performing a single regression analysis based on the processing time and the load for each of the B processing to the E processing affected by the load due to the business operation. It is an example of the estimation part which estimates the processing time.

The environment correction value calculation unit 22a compares the estimated value with the standard time (first reference application time) of the dummy patch 4b measured by the standard system 3, and performs environment correction for each of the A process to the E process. Coefficients (correction information) Ka to Ke are calculated.
FIG. 9 is a diagram illustrating an example of the environmental correction coefficient calculated by the environmental correction value calculation unit 22a illustrated in FIG.

Specifically, the environment correction value calculation unit 22a calculates the ratio between the estimated value in the user system 2 and the standard time actually measured in the standard system 3, and calculates the environment correction coefficient of hardware. For example, in the example illustrated in FIG. 9, the environment correction value calculation unit 22 a divides the estimated value of the user system 2 for A processing by the standard time of the standard system 3 as “3.23 / 5.23 = 0.62” as the environment correction coefficient Ka for A processing. "Get.

That is, the environment correction value calculation unit 22a determines the degree of difference in application environment when the dummy patch 4b is applied between the user system 2 and the standard system 3 based on the estimated application time and the first reference application time. Is an example of a correction information acquisition unit that acquires correction information for each of a plurality of processes.
The target patch specifying unit (extraction unit) 22b extracts one or more patches 4a applicable to the user system 2 from the plurality of patches 4a (correction data 4).

As described above, the correction data application program is distributed to all the user systems 2. For this reason, the correction data 4 may include a patch 4a that may not be applied in each user system 2. That is, the applicable patch 4a in the correction data 4 differs depending on the user system 2 due to a difference in software such as an operation application.

Therefore, the target patch specifying unit 22b specifies a patch 4a that can be applied to the user system 2 and creates a patch application list, and excludes the patch 4a that is not applied to the user system 2 from the processing in the application time calculation unit 22c.
Specifically, the target patch specifying unit 22b extracts patch information (at least a patch ID) from the patch application information 4c, and extracts an applied patch ID that has already been applied to the user system 2 from the user system 2.

Then, the target patch specifying unit 22b compares the extracted patch ID extracted from the patch application information 4c with the applied patch ID, and for the patch ID that matches the 6-digit character string that identifies the type among the patch IDs. The size of the 2-digit character string indicating the version number is determined.
For the extracted patch ID and the applied patch ID that match the 6-digit character string, the target patch specifying unit 22b has the applied patch ID version number smaller than the extracted patch ID version number, that is, the applied patch ID is older. In this case, the extracted patch ID is determined as the target patch 4a to be applied. At this time, the target patch specifying unit 22b registers the patch information (patch ID, reference application time, and priority) of the target patch 4a in the patch application list.

The patch application list has the same format as the patch application information 4c shown in FIG. The patch application list is created in the holding unit 21 and the like by the target patch specifying unit 22b when the target patch specifying unit 22b is activated.
Thus, since the target patch specifying unit 22b can extract the patch 4a applicable to the user system 2, the application time calculating unit 22c described later can accurately acquire the application time of the correction data 4. it can.

The application time calculation unit 22c (acquisition unit, conversion unit) estimates each application time when one or more patches 4a extracted by the target patch specifying unit 22b are applied to the user system 2 while the business is stopped. For example, the application time calculation unit 22c calculates the second reference application time in the patch application list (A process to E process time when the patch 4a is applied to the standard system 3) in the patch application list based on the environment correction coefficient. Is converted to application time (processing time of processing A to processing E).

Further, the application time calculation unit 22c can be applied to the user system 2 within the stop time for stopping the business based on the converted application time of each patch 4a and the priority of application of each of the plurality of patches 4a. One or more patches 4a are determined.
FIG. 10 is a diagram illustrating an example of the application time of each patch 4a calculated by the application time calculation unit 22c illustrated in FIG.

Specifically, the application time calculation unit 22c extracts patch information from the patch application list in descending order of priority during business operation, and sets each processing time (A process to E process) corresponding to the extracted patch information. Each is multiplied by the corresponding environmental correction factor (Ka to Ke). For example, in the example illustrated in FIG. 10, the application time calculation unit 22c uses the reference processing time of the patch 4a in the standard system 3 as the environmental correction coefficient for the A process as the processing time for the A process with the patch ID “123456-01”. Multiply “10.33 * 0.62 = 6.40”.

Further, the application time calculation unit 22c adds the sum of the results of the multiplication (conversion value, application time of the patch 4a) to the application time total (X) of the patch 4a to be applied. In the example illustrated in FIG. 10, the application time calculation unit 22c calculates “6.40 + 0.22 + 5.60 + 1.10 + 4.34 = 17.66” as the sum (application time) of the processing times A to E of the patch ID “123456-01”. Similarly, the sum of the processing times of the A process to E process of the other patch IDs is also obtained, and these sums are added together.

When the application time calculation unit 22c extracts all pieces of patch information from the patch application list and the addition to the total application time (X) is completed, the processing as the management unit 22 is completed. The total application time (X) at this time is a predicted value of the application time of the correction data 4.
In this way, the application time calculation unit 22c can calculate the application time of the patch 4a to the user system 2 by multiplying the application time of the patch 4a measured by the standard system 3 by the environment correction coefficient. At this time, since the target patch 4a that can be applied to the user system 2 is previously extracted as the patch application list by the target patch specifying unit 22b, the application time calculating unit 22c accurately predicts the application time of each user system 2. be able to.

By the way, depending on the maintenance time, before the application time calculation unit 22c extracts all pieces of patch information from the patch application list, the application time total (X) is a maintenance time designated in advance by the customer (user) of the user system 2 or the like. May be exceeded. In such a case, the application time calculation unit 22c sets the patch ID of the patch information extracted at the time of exceeding as the end patch ID. The end patch ID is a trigger for ending the application process within the maintenance time when the correction data 4 is applied to the user system 2 by the application processing unit 23.

Thus, in the user system 2, since the application time of each patch 4a can be calculated, the application time calculation unit 22c sums the application times in order from the patch 4a with the highest priority so that the maintenance time can be reached. A preliminary survey of applicable patches 4a can be performed. In the user system 2, the patch 4a to be applied to the user system 2 can be determined within a range that is completed within the maintenance time.

Conventionally, once the batch correction data application tool is started, it does not stop until the batch correction data application process is completed, so if the application time estimate by the customer is poor, the application process by the application tool has been determined in advance. There is a risk that the operation of the user system may be hindered.
If the customer determines that the estimated application time exceeds the maintenance time that can be secured, the customer does not start the application tool (does not apply the batch correction data) and applies one update patch to the user system. Will not be.

On the other hand, according to the application time calculation unit 22c, even when the maintenance time is limited, the priority is high within the given maintenance time based on the predicted application time of each patch 4a and the priority order. The patch 4a can be applied to the user system 2 in order. Therefore, stability and safety of the user system 2 can be ensured.
Moreover, when the application time of the correction data 4 is acquired by the application time calculation unit 22c, the management unit 22 can provide the acquired application time to the customer by, for example, displaying the acquired application time on a display (input / output unit 20e) or the like. it can.

Unlike the conventional application tool, the application processing unit (application unit) 23 can individually apply one or more patches 4 a of the correction data 4 to the user system 2.
For example, based on the patch application list, the application processing unit 23 applies one or more patches 4a determined by the application time calculation unit 22c to the user system 2 in the application order based on the priority order while the business is stopped.

At this time, when a value is set for the end patch ID, the application processing unit 23 compares the patch ID extracted from the patch application list in the application order with the end patch ID. Then, the application processing unit 23 applies the patch 4a if they are different as a result of the comparison, and ends the process without applying the patch 4a if they match.
As described above, according to the user system 2 according to the embodiment, the application time of the dummy patch 4b that does not affect the business operation in the user system 2 is measured, and the estimated application time is estimated from the measurement result. And the application time of the correction data 4 is acquired by the user system 2 based on the environment correction coefficient calculated based on the estimated application time and the first reference application time, and the second reference application time. That is, the target patch specifying unit 22b and the application time calculation unit 22c described above store the correction data 4 during the operation stop based on the estimated application time and the first and second reference application times of the patch application information 4c. 2 is an example of an acquisition unit that acquires an application time when applied to 2;

Note that the user system 2 can activate and operate the function of the management unit 22 and the function of the application processing unit 23 independently of each other. Therefore, the customer can grasp in advance and accurately the application time of the correction data 4 for making the maintenance plan of the user system 2 by the function of the management unit 22, and can accurately estimate the maintenance time. . Moreover, since the operation stop time of the user system 2 can be minimized, the operating rate of the user system 2 can be improved.

[1-4] Functional Configuration of Standard System Next, the functional configuration of the standard system 3 will be described with reference to FIG. FIG. 11 is a diagram illustrating a functional configuration example of the standard system 3 illustrated in FIG. 1.
As shown in FIG. 11, the standard system 3 includes a holding unit 31 and a management unit 32. The holding unit 31 is realized by the memory 30b or the storage unit 30c shown in FIG. 3, and the management unit 32 is realized by the CPU 30a.

The holding unit 31 holds correction data 4, including one or more (a plurality in the example illustrated in FIG. 11) patches 4a, one dummy patch 4b, and patch application information 4c. Since these pieces of information held by the holding unit 31 are the same as the information held by the holding unit 21, a detailed description thereof will be omitted.
The management unit 32 generates the patch application information 4c, and includes a measurement unit 32a and a priority setting unit 32b.

The measurement unit 32a applies the correction data 4 and the dummy patch 4b to the standard system 3 in the absence of a load, measures each processing time of the A process to the E process, and applies the patch application information as shown in FIG. The patch ID and A processing time to E processing time information are set in 4c.
The measurement unit 32a applies the correction data 4 and the dummy patch 4b to the standard system 3 a plurality of times in order to obtain an accurate measurement result, and obtains the average of the measurement results obtained a plurality of times as each processing time. May be.

The priority order setting unit 32b sets the priority order of each patch ID (patch 4a) designated by the provider or the like in the patch application information 4c. When the standard system 3 acquires the modification data 4 and the dummy patch 4b from the provider or the like, if the patch application information 4c including the patch ID and priority is acquired, the priority setting unit 32b is omitted. May be.
[1-5] Operation Example Next, with reference to FIGS. 12 to 17, an operation example of the user system 2 in the information processing system 1 as an example of the embodiment configured as described above will be described.

FIG. 12 is a diagram for explaining the flow of processing in the information processing system 1 shown in FIG. 1, and FIG. 13 is a flowchart for explaining an example of processing by the user system 2 shown in FIG. FIGS. 14 to 17 are flowcharts for explaining an example of the coefficient calculation process, the target patch extraction process, the application time prediction process, and the application patch optimization process by the user system 2 shown in FIG.

As shown in FIG. 12, the hardware performance of the user system 2 is as follows: the operation clock of the CPU 20a is 2.5 GHz, the storage area of the memory 20b is 4 Gbytes, the reading speed of the CD drive 20g is 8 times, and the storage area of the HDD 20c. Is 500 Gbytes. The hardware performance of the standard system 3 is as follows: the operation clock of the CPU 30a is 1.5 GHz, the storage area of the memory 30b is 3 Gbytes, the reading speed of the CD drive 30g is 6 times faster, and the storage area of the HDD 30c is 300 Gbytes. To do. Further, it is assumed that the business (predetermined processing) in the user system 2 and the load processing in the standard system 3 are both a Web service and a database service.

[1-5-1] Coefficient Calculation Processing First, coefficient calculation processing by the user system 2 will be described with reference to FIGS.
In the user system 2, when the correction data application program is read and the management unit 22 is activated, the processing of the environment correction value calculation unit 22a starts.

The environmental correction value calculation unit 22a calculates an environmental correction coefficient based on the application result of the dummy patch 4b in the standard system 3 and the user system 2 (see step S1 in FIG. 13).
Specifically, as shown in FIG. 14, the environment correction value calculation unit 22a applies the dummy patch 4b to the user system 2 in business operation a plurality of times, and the processing times of the A process to the E process for each time are measured. (Step S11).

Next, the processing time (estimated values (a to e)) of the A process to the E process when the user system 2 is stopped (when there is no load) is calculated from the processing time measurement result by the environment correction value calculation unit 22a. It is estimated (step S12, process T1 in FIG. 12).
Further, the application time (standard time (a ′ to e ′), first reference application time) of the dummy patch 4b in the standard system 3 is acquired from the patch application information 4c by the environment correction value calculation unit 22a (step S13). ).

Then, the estimated values (a to e) of the A process to E process are respectively divided by the standard time (a ′ to e ′) by the environment correction value calculation unit 22a, and the environment correction coefficients (Ka to Ke) are respectively calculated. After the calculation (step S14, process T2 in FIG. 12), the coefficient calculation process ends.
[1-5-2] Target Patch Extraction Processing Next, the target patch extraction processing by the user system 2 will be described with reference to FIGS. 12, 13, and 15.

When the processing of the environmental correction value calculation unit 22a is completed, the processing of the target patch specifying unit 22b starts.
The target patch specifying unit 22b extracts the target patch 4a to be applied to the user system 2 from the patch application information 4c (step S2 in FIG. 13 and process T3 in FIG. 12).
Specifically, as shown in FIG. 15, one patch ID is extracted from the patch application information 4c by the target patch specifying unit 22b (step S21). Further, the target patch specifying unit 22b refers to the applied patch of the user system 2, and determines whether there is an applied patch of the same type as the extracted patch ID (matching the 6-digit character string of the patch ID). (Step S22).

When it is determined that there is an applied patch ID of the same type as the extracted patch ID (Yes route in step S22), the target patch specifying unit 22b extracts the patch ID of the applied patch from the user system 2 (step S22). S23). Further, the target patch specifying unit 22b determines whether the applied patch is older than the extracted patch 4a (whether the two-digit character string of the applied patch ID is smaller than the two-digit character string of the extracted patch ID). (Step S24).

If it is determined that the applied patch is not older than the extracted patch 4a (for example, the same version) (No route in step S24), the extracted patch 4a has already been applied, and the process proceeds to step S21. To do. On the other hand, when it is determined that the applied patch is older than the extracted patch 4a (Yes route in step S24), the target patch specifying unit 22b adds the patch information of the target patch 4a corresponding to the extracted patch ID to the patch application list. (Step S25), the process proceeds to Step S26.

In step S26, the target patch specifying unit 22b determines whether there is an undetermined patch 4a in the patch application information 4c (step S26), and when it is determined that there is an undetermined patch 4a (in step S26). Yes route), the process proceeds to step S21. On the other hand, if it is determined that there is no undetermined patch 4a (No route in step S26), the target patch end process ends.

If it is determined in step S22 that there is no applied patch ID of the same type as the extracted patch ID (No route in step S22), the process proceeds to step S25. In the case of the No route in step S22, since there is no applied patch of the same type as the extracted patch 4a in the user system 2, there is a possibility that the extracted patch 4a is not applied in the application process. However, since it is at the stage of the E process shown in the example of FIG. 6 that it can be determined whether or not the extracted patch 4a is applied, the difference in processing time compared to the case where the patch 4a is normally applied is It doesn't matter.

[1-5-3] Application Time Prediction Processing Next, application time prediction processing by the user system 2 will be described with reference to FIG. 12, FIG. 13, and FIG.
When the process of the target patch specifying unit 22b is completed, the process of the application time calculating unit 22c starts.

The application time calculation unit 22c predicts the application time of the correction data 4 based on the application time (second reference application time) of the target patch 4a in the patch application list in the standard system 3 and the environment correction coefficient ( Step S3).
Specifically, as shown in FIG. 16, the application time calculation unit 22c initializes the application time total (X) value of the correction data 4 (step S31).

Further, the application time calculation unit 22c extracts one patch ID from the patch application list in descending order of priority (step S32), and further, processing times (A to E) corresponding to the extracted patch 4a. E) is extracted (step S33).
Then, the application time calculation unit 22c multiplies the processing times (A to E) by the corresponding environmental correction coefficients (Ka to Ke), and sums the results to add to the application time total (X) (step). S34, process T4 of FIG.

Next, the application time calculation unit 22c compares the maintenance time with the application time total (X), and determines whether or not the maintenance time is greater than the application time total (X) (step S35, processing in FIG. 12). T5). When it is determined that the maintenance time is longer than the total application time (X) (Yes route in step S35), the application time calculation unit 22c determines whether the extracted patch 4a is the last data in the patch application list. (Step S36).

If it is determined that the extracted patch 4a is not the last data in the patch application list (No route in step S36), the process proceeds to step S32. On the other hand, when it is determined that the extracted patch 4a is the last data in the patch application list (Yes route in step S36), the application time prediction process ends.
If it is determined in step S35 that the maintenance time is equal to or less than the total application time (X) (No route in step S35), the application time calculation unit 22c sets the patch ID of the extraction patch 4a as the end patch ID. Then (step S37), the application time prediction process ends.

When the process of the application time calculation unit 22c is completed, the application unit 22 provides the application time total (X) to the customer.
[1-5-4] Applied Patch Optimization Processing Next, applied patch optimization processing by the user system 2 will be described with reference to FIG. 12, FIG. 13, and FIG.

In the user system 2, when the application processing unit 23 is started when the job is stopped (maintenance time is reached), the application patch optimization processing by the application processing unit 23 starts.
In the application processing unit 23, the patch application list is optimized so as to be applied to the user system 2 from the target patch 4a having high importance (step S4 in FIG. 13 and process T6 in FIG. 12). .

Specifically, as shown in FIG. 17, the application processing unit 23 extracts one patch ID from the patch application list in descending order of priority (step S41).
Next, the application processing unit 23 repels whether or not the extracted patch ID is the same as the end patch ID (step S42).
When it is determined that the extracted patch ID is different from the end patch ID (No route in step S42), the application processing unit 23 applies the patch 4a of the extracted patch ID to the user system 2 (step S43), and the process is step. The process proceeds to S41. On the other hand, when it is determined that the extracted patch ID is the same as the end patch ID (Yes route in step S42), the applied patch optimization process ends.

Thus, the process by the user system 2 ends.
[2] Others While the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to such specific embodiments, and various modifications and changes can be made without departing from the spirit of the present invention. It can be changed and implemented.

For example, although the A process shown in FIG. 6 has been described as a process in which the CD drives 20g and 30g read the patch data recorded on the CDs 20h and 30h and temporarily store them in the storage area, the A process is limited to this. is not. For example, the correction data application program may be compressed in the standard system 3 or another device and distributed to one or more user systems 2 via a network.

In this case, the A process is the A ′ process in which the patch data downloaded in advance by the interface unit 20d and stored in the HDD 20c, 30c, etc. is read by the CPU 20a, 30a from the HDD 20c, 30c, etc. and temporarily stored in the memory 20b, 30b, etc. It is good. The A ′ process is performed by the CPUs 20a and 30a and the HDDs 20c and 30c, and thus is affected by a load during business operation. That is, the processing time of the A ′ process also depends on both the hardware performance and the business operation state (load state) (see the lower part of FIG. 6). Therefore, the estimated value (estimated application time) for the processing time of the A ′ process is estimated by the method shown in FIG. 7 for the B process and the D process.

In addition, the application processing unit 23 described above performs application according to priority when all the patches 4a in the patch application list can be applied within the maintenance time (when no end patch ID is set). Instead, for example, the patches 4a may be applied in the order of storage in the patch application list.
Further, when the application processing unit 23 applies the patches 4a in the application order based on the priority order, the patch 4a that has not been applied may be applied when the application processing unit 23 is activated next time. Alternatively, the user system 2 may store the patch 4a that has not been applied, and merge the patch 4a that has not been applied into the new correction data 4 when a new correction data application program is received. .

Further, the user system 2 determines the application time of the patch 4a in the standard system 3 based on the environment correction coefficient calculated from the relationship between the application time of the dummy patch 4b in the standard system 3 and the user system 2. Although converted into application time, it is not limited to this.
For example, the user system 2 may calculate a correction coefficient (correction information) indicating the degree of application time difference between the dummy patch 4b and each patch 4a in the standard system 3. In this case, the user system 2 may convert the estimated application time in the user system 2 into the application time when the correction data 4 is applied to the user system 2 while the work is stopped, based on the calculated correction coefficient.

Note that all or some of the various functions of the user system 2 and the standard system 3 according to the embodiment may be realized by a computer (including a CPU, an information processing apparatus, and various terminals) executing a predetermined program. Good.
The program is provided in a form recorded on a computer-readable recording medium such as a flexible disk, CD, DVD, or Blu-ray disk (for example, recording media 20h and 30h shown in FIG. 3). Examples of CD include CD-ROM, CD-R, CD-RW and the like. Examples of DVD include DVD-ROM, DVD-RAM, DVD-R, DVD-RW, DVD + R, DVD + RW, and the like.
