Description

  The present invention relates to an installation support apparatus, an installation support program, and an installation support method. The present invention particularly relates to an automatic installation system for OSS (open source software), an automatic tuning method for environment variables of OSS, and the like.

In general, OSS (Open Source Software) has the following characteristics because the source code is released free of charge.
(1) The risk of being fixed to a specific technology or product is small.
(2) Anyone can quickly respond to security flaws.
(3) It can be reused for other information systems.
(4) The cost for the information system can be expected to be reduced.
Therefore, in Japan, OSS utilization policies such as Linux (registered trademark) are being promoted in order to strengthen the competitiveness of the domestic IT (information technology) industry. Conventionally, when installing an OSS, tuning such as directly rewriting the setting file with an editor or setting environment variables has been manually performed.

Traditionally, as a method of automatically installing software on a computer, creating a build plan that defines the software to be installed on the receiving computer, transferring the build plan to the receiving computer, and building on the receiving computer -Some of them included execution of a plan (for example, see Patent Document 1). Similarly, when a request including a functional requirement is received, the directory is queried to determine whether there is a single component that satisfies the functional requirement, and there is no single component that satisfies the functional requirement. In response to the determination, there is a step of identifying a plurality of functions that satisfy the functional requirements when combined according to a certain combination method, and identifying a plurality of components that satisfy the plurality of functions. (For example, refer to Patent Document 2).
Special table 2004-533032 gazette JP-T-2006-500650

In order to utilize OSS (open source software), there are the following three problems, and it is necessary to evaluate and verify the suitability of OSS in advance.
(1) License issues (infringement risks of intellectual property rights such as copyrights and patents)
(2) Quality issues (rapid response when trouble occurs, risk of dealing with warranty liability)
(3) Technical issues (architecture design risks such as scalability and performance)
That is, when installing the OSS, the above three types of risks must be evaluated and tuning must be performed based on the evaluation (details of the above three types of risks will be described later). In particular, when a plurality of OSSs are installed (for example, when OSS basic software, middle software, and business software are combined), different tuning is required depending on which OSS is combined. However, conventionally, tuning has been performed manually, and there has been a problem that it is difficult to perform appropriate tuning in accordance with various risk evaluations. In addition, in the conventional method, since risk evaluation is not performed when software is automatically installed, there is a high possibility that various problems in terms of license, quality, and technology are likely to occur after installing OSS. was there.

  In addition, for the default values and setting conditions of OSS environment variables that conform to the external environment conditions of the business system to be installed, templates that have been installed in the past are obtained via the user, and the latest failure information is referenced and collected via the Internet. As a result, there is a problem that a specialized system engineer and software engineer who is familiar with both the business and the system have to investigate and design it as an advance preparation for the installation work.

  An object of the present invention is to perform appropriate tuning in accordance with various risk evaluations in terms of license, quality, and technology when installing an OSS, for example.

  Further, the present invention, for example, when installing an OSS, tunes the setting values of OSS environment variables that minimize the license, quality, and technical risks corresponding to the external environment conditions of the business system. With the goal.

An installation support apparatus according to an aspect of the present invention includes:
Each of the items representing the setting conditions is divided into a plurality of items, each representing an environmental condition to be installed by the software and a setting condition at the time of the software installation. An installation support device for determining a recommended value of
Each setting candidate value is associated with each combination of an environment candidate value that can be taken by each item representing the environmental condition and a setting candidate value that is a value that can be taken by each of the items representing the setting condition.

An environment candidate value input unit for inputting at least one environment candidate value from an input device;
Of the risk evaluation values stored by the risk evaluation value storage unit, the risk evaluation value corresponding to the environmental candidate value input by the environmental candidate value input unit is read from the storage device, and the read risk evaluation value is A risk evaluation value totaling unit that totals the processing device for each setting candidate value;
Among the risk evaluation values tabulated by the risk evaluation value tabulation unit, a risk evaluation value selection unit that selects a risk evaluation value representing a lower risk by a processing device for each item representing the setting condition;
A recommended value output unit that outputs a setting candidate value corresponding to the risk evaluation value selected by the risk evaluation value selection unit to an output device as a recommended value of each item representing the setting condition. .

  According to one aspect of the present invention, in the installation support apparatus, the risk evaluation value storage unit corresponds to each combination of the environment candidate value and the setting candidate value, and the setting condition and each environment represented by each setting candidate value. A risk evaluation value representing a risk that a failure occurs during execution of software under the environmental condition represented by the candidate value, and the risk evaluation value totaling unit is a risk evaluation value stored in the risk evaluation value storage unit The risk evaluation value corresponding to the environmental candidate value input by the environmental candidate value input unit is aggregated for each corresponding setting candidate value, and the risk evaluation value selection unit is aggregated by the risk evaluation value aggregation unit Among the values, a risk evaluation value representing a lower risk is selected for each item representing the setting condition, and a recommended value output unit corresponds to the risk evaluation value selected by the risk evaluation value selection unit. For example, when installing OSS (Open Source Software), various license risks, quality aspects, and technical risks are output. It is possible to perform appropriate tuning according to the evaluation.

  When the OSS automatic tuning apparatus 200 represents the environmental conditions of the business system 104 that is the OSS installation target and the setting conditions at the time of the OSS installation by dividing them into a plurality of items, the OSS automatic tuning apparatus 200 performs the following Based on the value of each item representing the condition, the recommended value of each item representing the setting condition is determined (that is, the setting condition is tuned). The OSS automatic tuning apparatus 200 may perform tuning not only for the OSS but also for other types of software. Here, the items representing the environmental conditions are, for example, those in which the external environmental conditions of the business system 104 described above are classified into usage environments, terminal environments, network environments, and the like, and further divided into detailed items. The items representing the setting conditions are, for example, the above-described OSS version, environment variables, parameters in the setting file, and the like, that is, environment variables. The recommended value is, for example, an OSS environment variable value extracted as a result of the tuning described above (hereinafter, such an OSS environment variable value is also referred to as a “tuning value”).

When tuning is performed in consideration of technical (extensibility) risk, the environment candidate value input unit 204 selects an environment condition at the time of OSS installation from among the environment candidate values that can be taken by one of the items representing the environment condition. Both the value to be expressed and the value to represent the environmental condition when the environmental condition is changed after the OSS is installed are input. In the present embodiment, the environmental candidate value input unit 204 inputs a value representing an environmental condition at the time of OSS installation from the input device 253 and records the value in the business system external environmental condition file 116, for example. Correspondence relations between the environmental candidate values recorded in the business system external environmental condition file 116 and the environmental candidate values (environmental conditions to be risk-evaluated) assumed when the future business system 104 is expanded and the risk requirements of the OSS. Is recorded in the risk / environment determination table 601, for example. Specifically, there are three types of risks: license (risk of intellectual property rights infringement) risk during installation of OSS, quality (effectiveness as a countermeasure against failure) risk, and technical (scalability) risk Each value representing an environmental condition for tuning in consideration of the risk item is input, and the correspondence between each value and the evaluation target of each risk item is recorded in the risk / environment determination table 601.

Output to. The recommended value output unit 207 reads the default value stored by the default value storage unit 203 for each item representing the setting condition from the storage device 251, and the risk default value selected by the risk evaluation value selection unit 206 is read. When it is different from the setting candidate value corresponding to the evaluation value, both the default value and the recommended value of each item representing the setting condition are output to the output device 254. At this time, for the recommended values of the parameters set in the OSS setting file, the recommended value output unit 207 displays the recommended values of each parameter on a display screen provided with a tab for each setting file in which each parameter is set. , Output in the corresponding tab. In the present embodiment, the recommended value output unit 207 records the tuning value (recommended value) and the default value in, for example, the OSS environment variable tuning value output file 801. Then, the tuning value and default value recorded in the OSS environment variable tuning value output file 801 are output to the output device 254.

  The flow shown in the flowchart of FIG. 5 corresponds to a processing procedure of an OSS automatic tuning program (an example of an installation support program) executed on a computer that implements the OSS automatic tuning apparatus 200. In this processing procedure, the OSS automatic tuning program causes the computer to execute the following processes, for example.

  The failure storage unit 201 acquires the OSS failure information 114 from the Internet, and stores the acquired OSS failure information 114 in the magnetic disk device 920 (step S101: failure storage process). The OSS failure information 114 includes a combination of a value indicating an environmental condition when a failure has occurred in the past, a value indicating a setting condition, and the phenomenon that has occurred.

  An example of values representing environmental conditions is shown in FIG. In this example, the external environment conditions of the document management system to be the OSS installation target are three “environment types” of “(i) usage environment”, “(ii) terminal environment”, and “(iii) network environment”. It is classified. Each “environment type” is further divided into “environmental conditions” such as “contract type”, “usage type”, “number of connected terminals”, “purpose of use”, and “special protocol”. Each of the “options” in each “environment condition” (hereinafter referred to as “external environment condition value”) corresponds to a value representing the environment condition.

  An example of a value indicating the setting condition and a phenomenon that occurs as a failure is shown in FIG. In this example, the failure that occurs when the combination of “server” and “middle software” is AP server 301 and Apache (an example of HTTP server OSS 311) or Tomcat (an example of AP server OSS 315) is “(A) terminal “Freeze”, “(B) Server error”, “(C) Screen white display”, “(D) Log enlarging”, “(E) Response time recording”, “(F) Two ja settings”, “( It is classified into a plurality of “failure types” such as “G) Tomcat stop”, “(H) JDBC connection time”, and “(I) session-timeout”. Each “failure type” indicates which environment variable value is changed for what purpose and how (“setting file”, “fault countermeasure”, “fault countermeasure purpose”). Furthermore, it is indicated which kind of risk is affected when the value of the environment variable, that is, the OSS environment variable value is changed (“risk”). As described above, each OSS environment variable value corresponds to a value representing a setting condition.

  The OSS failure information 114 includes information as shown in FIGS. For example, as an external environment condition value, “environment type” is “(ii) terminal environment”, “environment condition” is “(2) purpose of use”, “option” is “use other system or OA”, The OSS environment variable value includes information indicating that when the Apache version is 2.0, a failure having the “failure type” of “(A) terminal freeze” has occurred.

  The default value storage unit 203 stores the default value of each environment variable in advance or at httpd. conf (an example of HTTP communication protocol setting file 313) or the like, obtained from each OSS environment variable / setting file 106, 108, 110 and stored in the business system installation template setting file 117 in the magnetic disk device 920 (step S102: Default value storage processing).

  As the business system introduction template setting file 117, a file including information as shown in FIGS. 8 and 9 is stored. The document management system AP server setting file shown in FIG. 8 is an example of the environment variable / setting file 108 of the AP server 301. For example, in this document management system AP server setting file, “Item No.” is “19” and “Setting Item” is “Default Value” of “Web.xml where Tomcat is installed” is “C: \ Program Files \ "Apache Group \ Tomcat 4.1 \ web.xml". In addition, the document management system Tomcat_Web. The xml configuration file is an example of the environment variable / configuration file 108 of the AP server OSS 315. For example, this document management system Tomcat_Web. In the XML configuration file, “default value” of “physical name” is “session-timeout”, “logical name” is “session timeout”, and “description” is “expiration time (unit: minutes) of http session” is “ 30 ".

  The risk evaluation value storage unit 202 reads the OSS failure information 114 stored in the failure storage unit 201 in step S101 from the magnetic disk device 920, and includes the external environment condition value and the OSS environment variable value included in the read OSS failure information 114. The CPU 911 sets the score of the risk evaluation value corresponding to the combination of the failure with the “failure type” as a higher score. Then, the set score is stored in the magnetic disk device 920 (step S103: risk evaluation value storage processing). Here, the higher the score, the higher the risk, and the lower the score, the lower the risk. The score of the risk evaluation value stored in the magnetic disk device 920 by the risk evaluation value storage unit 202 corresponds to the OSS failure risk information described above.

  In an example to be described later, the risk evaluation value storage unit 202 sets environment / failure evaluation information (◯: normal operation confirmed, x: failure occurrence, no mark: unconfirmed) by the CPU 911, and environment / failure determination of the magnetic disk device 920. Tables 501 and 502 are stored. “○: Normal operation confirmed” indicates that there is actually no actual application and there are few problems. “×: Failure occurred” indicates that there was an actual application and there was a problem. “No mark: Unconfirmed” Indicates that the risk is unknown because there is no application record. Therefore, although the environment / failure determination tables 501 and 502 can be created from the system application results, the OSS business system introduction template 115 obtained / stored via the user and the OSS failure information 114 referred / stored / collected via the Internet. Increases, the accuracy of the environment / failure determination tables 501 and 502 increases.

  The environment candidate value input unit 204 receives an input of the current external environment condition value by the operator from the keyboard 902 or the mouse 903 (step S104: environment candidate value input process). When the operator requests the execution of tuning in consideration of technical risks, the environment candidate value input unit 204 is also capable of inputting external environment condition values assumed when the future document management system is expanded. Accept from 902 or mouse 903.

  In the example to be described later, the environment candidate value input unit 204 includes items to be considered (license risk), quick response in the event of trouble, infringement of intellectual property rights such as copyrights and patent rights, Regarding the response to collateral liability, items that should be taken into account in the current design (quality risks), architecture design such as extensibility and performance, etc. should be considered because there is a possibility of future expansion etc. The operator inputs the combination of the three types of risk items (technical risks) and the external environmental condition values, accepts the input from the keyboard 902 and the mouse 903, and the risk / environment of the magnetic disk device 920. The determination table 601 is stored. The environment candidate values that can be entered are designed each time by a system engineer (or operator) based on the OSS business system introduction template 115 according to the business content and the configuration of the business system 104 (for example, the type of the business system 104). Templates for each server, each middleware).

  FIG. 10 shows an example of a GUI (graphical user interface) for the operator to input external environmental condition values and the like. In this example, the operator selects “document management system” as the “business system” on the operation screen 401 output to the display device 901 by the environment candidate value input unit 204. In addition, “option” of each “environment condition” of each “environment type” is selected as the current external environment condition value. Although only a part is shown in FIG. 10, for example, “single use” is selected as “option” of “use form” of “(i) use environment”, and “number of connected terminals” of “(ii) terminal environment”. “300 or more and less than 1,000” can be selected as “option”, and “metaframe use” can be selected as “option” of “special protocol” of “(iii) network environment”. The value selected by the operator is accepted by the environment candidate value input unit 204 when the operator presses the “Register” button with the keyboard 902 or the mouse 903.

  In the example of FIG. 10, the operation screen 401 is also a screen for inputting settings for installing OSS or the like in the AP server 301. When the operator selects the AP server 301 on the operation screen 401 or selects the operation screen 401 for the AP server 301, the OS, JAVA (registered trademark) version, middleware recommended to be installed on the AP server 301 Etc. are displayed. Some of these software may already be installed. In this example, it is assumed that Apache and Tomcat are recommended as middleware. Therefore, the operation screen 401 includes Apache and Tomcat environment variable / setting file 108, httpd. conf, workers. properties, web. xml, server. A tab for setting xml is displayed. Although only a part is shown in FIG. 10, for example, httpd. In the conf setting tab, the operator can select the Apache license version using the “Browse” button, and use the check box to indicate whether he / she agrees with the license agreement. At this time, based on the Apache license version selected by the operator, information on the license risk of the OSS that the operator is about to install is displayed. In addition, the operator uses another “reference” button to execute httpd. A conf folder path or a file name can be selected. The value selected by the operator is accepted by the environment candidate value input unit 204 in the same manner as the external environment condition value when the operator presses the “Register” button with the keyboard 902 or the mouse 903.

  FIG. 11 shows an example of information related to OSS license risk such as infringement of intellectual property rights. The fact that the obligation to release source code affects other programs is called “propagation”. In this example, the risk of GPL type licenses (Gnu / Public / License), which is the most strict as an OSS license risk, is “large”. (The propagation characteristics in this case are also called “GPL pollution”), the risk of MPL type license (Mozilla, Public, License) that is less stringent than GPL is “medium”, and the BSD type license (Berkeley Software, which is extremely loose)・ Distribution risk is defined as “small”. For example, the environment candidate value input unit 204 may immediately display information on the corresponding license risk on the operation screen 401 each time the operator selects an Apache license version. Then, the table shown in FIG. 11 may be stored in the magnetic disk device 920 in advance as a table to be referred to. In the example of FIG. 11, “license type” and “license risk” are not shown for software other than OSS, but similar information may be defined.

  In this way, from the viewpoint of using OSS, paying attention to “propagation” that requires attention, the license risk is categorized and displayed in three types: “large”, “medium”, and “small”. It is easy to avoid license risk when installing OSS.

  In the example of FIG. 10, the operation screen 401 is also the tuning result output screen 118 described above, which will be described later.

  The risk evaluation value totaling unit 205 is a score corresponding to the external environmental condition value input by the environment candidate value input unit 204 in step S104 out of the risk evaluation value scores stored in the risk evaluation value storage unit 202 in step S103. Are read from the magnetic disk device 920, and the read points are totaled by the CPU 911 for each combination of the corresponding OSS environment variable value and “failure type”. Then, the total score is further totaled by the CPU 911 for each corresponding OSS environment variable value (step S105: risk evaluation value total processing).

  In an example to be described later, the risk evaluation value totaling unit 205 includes environment / failure evaluation information (◯: normal operation) in the environment / failure determination tables 501 and 502 of the magnetic disk device 920 stored in the risk evaluation value storage unit 202 in step S103. Risk score corresponding to the external environmental condition value in the risk / environment determination table 601 input by the environmental candidate value input unit 204 in step S104 from the magnetic disk device 920. The CPU 911 totalizes the read points and the read points for each combination of the corresponding OSS environment variable value and the “failure type”. Then, the total score is further totaled by the CPU 911 for each corresponding OSS environment variable value, and stored in the risk / failure determination tables 701 and 702 (environment variable determination table) of the magnetic disk device 920.

  The risk assessment value selection unit 206 selects the lowest score among the risk assessment values scored by the risk assessment value aggregation unit 205 in step S105 for each environment variable by the CPU 911 (step S106: risk assessment value selection). processing).

  The recommended value output unit 207 outputs the OSS environment variable value corresponding to the score of the risk evaluation value selected by the risk evaluation value selection unit 206 in Step S106 to the display device 901 as each tuning value of the environment variable (Step S106). S107: Recommended value output processing). Also, the recommended value output unit 207 reads the default value stored in the default value storage unit 203 in step S103 from the magnetic disk device 920 for each environment variable, and outputs the read default value to the display device 901. The recommended value output unit 207 determines in the CPU 911 whether or not tuning of all environment variables (or all environment variables related to one setting file) has been completed (step S108). If it is determined in step S108 that all environment variables have not been tuned ("No"), steps S105 to S107 are repeated to execute the next environment variable tuning. If it is determined in step S108 that all environment variables have been tuned ("Yes"), the process ends.

  In the example of FIG. 10, the httpd. In the conf tab, “300” is output as the default value of Timeout and “60” is output as the tuning value of Timeout. The operator can change the value of Timeout from the default value “300” to the tuning value “60” on the operation screen 401. When the operator presses the “Register” button with the keyboard 902 or the mouse 903, the recommended value output unit 207 accepts the input of the value of Timeout, and this Timeout value is input to the OSS automatic installation execution device 119 of the OSS automatic installation system 100. input. The OSS automatic installation execution apparatus 119 sets the input Timeout value to httpd. Execute Apache installation after reflecting on conf. Further, in the example of FIG. The Apache license version is displayed in the conf tab. As described above, this may be a value selected by the operator, or may be a default value or a tuning value of the license version. Good. In any case, when the operator presses the “Register” button with the keyboard 902 or the mouse 903, the recommended value output unit 207 accepts the input of the Apache version, and this version is executed by the OSS automatic installation system 100 for executing the OSS automatic installation. Notify the device 119. The OSS automatic installation execution device 119 executes installation of the notified version of Apache. As described above, the recommended value output unit 207 inputs the environment variable set on the operation screen 401 to the OSS automatic installation execution apparatus 119. Here, the recommended value output unit 207 may transmit the environment variable set on the operation screen 401 to the other system 103 via the network 102. As a result, the other system 103 can use the settings made on the operation screen 401. In addition, the recommended value output unit 207 may output environment variables set on the operation screen 401 to a list screen so that they can be referenced and printed.

  Thus, in this embodiment, as shown in the example of FIG. 10, “business system”, “server name”, middleware (tab heading), setting file (tab heading), “environment variable name” By the parameter setting tuning operation of the five layers, a plurality of OSS environment variables having different setting procedures and display formats can be set by a unified operation. In addition, since a plurality of OSS environment variables having different setting procedures and display formats can be managed in a plurality of tabs, convenience in operation of the business system 104 is improved.

  The specific algorithm for extracting the OSS environment variable value based on the OSS failure risk information has been described above. In the following, this algorithm will be further described with two specific examples.

  First, a first example is shown.

  In the first example, in step S101, the failure storage unit 201 acquires OSS failure information 114 related to the Apache version of the AP server 301 from the Internet and stores it in the magnetic disk device 920.

  In step S102, the default value storage unit 203 stores the default value of the Apache version as “2.2” in the magnetic disk device 920 in advance.

  In step S103, the risk evaluation value storage unit 202 stores the environment / failure determination table 501 shown in FIG. 12 in the magnetic disk device 920 as OSS failure risk information. The environment / failure determination table 501 includes risk evaluation values corresponding to “2.0” and “2.2” (default values stored in step S102) that can be set as the Apache version of the AP server 301. The score is shown for each combination of the external environmental condition value (vertical axis) and the “failure type” of failure (horizontal axis). In the environment / failure determination table 501, when the normal operation of Apache is confirmed for the combination of the external environment condition value corresponding to each item, the “failure type” of failure, and the version of Apache, Is set, and the occurrence of a failure of “failure type” corresponding to the past is recorded in the OSS failure information 114, “x” is set in that item. If unconfirmed, nothing is set for the item (no mark). In other words, “○” indicates that there was actually a problem with application and there were few problems, “×” indicates that there was actually a problem with application, and an unmarked item indicates actual application. Indicates that there was a problem. Therefore, as the application record increases, the accuracy of the environment / failure determination table 501 increases. Here, “○” is 1 point, “×” is 3 points, and no mark is 2 points, and risk is quantitatively evaluated.

  In step S104, the environmental candidate value input unit 204 accepts input of the current external environmental condition value and the external environmental condition value assumed when the future document management system is expanded from the keyboard 902 or the mouse 903, The risk / environment determination table 601 shown in FIG. 13 is stored in the magnetic disk device 920. In this example, the environmental candidate value input unit 204 further accepts input of designation of a risk to be evaluated in combination with each external environmental condition value. Since the risk / environment determination table 601 has a common format for all OSSes, the risk / environment determination table 601 does not necessarily need to be input for each OSS, but in this example, only the Apache is targeted. Therefore, this risk / environment determination table 601 shows combinations of risks (vertical axis) and external environmental conditions (horizontal axis) to be evaluated when Apache is installed in the AP server 301. In the risk / environment determination table 601, when a combination of a risk and an external environmental condition value corresponding to each item is designated as an evaluation target, “Δ” is set for the item. If not applicable, nothing is set for the item (no mark). Here, weighting is performed according to the type of risk to which the item “Δ” corresponds. Therefore, the license risk weight is 1 (times), the quality risk weight is 3 (times), and the technology risk weight is 2 (times). As described above, the license risk is an item that should be considered for infringement of intellectual property rights such as copyrights and patent rights. Quality risk is an item that should be considered in the design of the current document management system for prompt response in case of trouble and response to warranty liability. Technical risk is a risk item that should be considered for architecture design such as extensibility and performance when there is a possibility of extending the document management system in the future. In the example of FIG. 13, the current external environment condition value is “single use” as “option” in which “environment type” is “(i) use environment” and “environment condition” is “(2) use form”. The external environmental condition value when the future document management system is expanded is set to “shared use”. For this reason, the former is an evaluation target for quality risk, and the latter is an evaluation target for technical risk. Similarly, as an “option” in which “environment type” is “(ii) terminal environment” and “environment condition” is “(1) number of connected terminals”, the current external environment condition value is “300 or more, The external environmental condition value when the future document management system is expanded is “1,000 or more and less than 5,000” or “5,000 or more”. For this reason, the former is an evaluation target for quality risk, and the latter is an evaluation target for technical risk.

  In step S105, the risk evaluation value totaling unit 205 includes the environment / failure determination table 501 stored in the risk evaluation value storage unit 202 in step S104 and the risk / environment determination table input by the environment candidate value input unit 204 in step S102. 601 is read from the magnetic disk device 920. Then, the risk evaluation value totaling unit 205 extracts the row data of the environment / failure determination table 501 by the CPU 911 using the external environment condition value corresponding to the item for which “Δ” is set in the risk / environment determination table 601 as a key. . The risk evaluation value totaling unit 205 assigns one item for which “○” is set in the extracted row data, three items for which “×” is set, and two items for which there is no mark, and is a risk / environment judgment table. Weighting is performed according to the type of risk corresponding to the item for which “Δ” is set in 601. That is, for quality risk line data, the score for each item is tripled, and for technical risk line data, the score for each item is doubled. Then, the risk evaluation value totaling unit 205 inserts each row data into the risk / failure determination table 701 shown in FIG. 14 and stores it in the magnetic disk device 920.

Hereinafter, the risk evaluation value aggregation processing in step S105 will be described for each row of the risk / failure determination table 701 in FIG.
(1) Corresponds to items in which “risk” is “license risk” and “evaluation target” is “infringement of intellectual property rights” among items for which “△” is set in the risk / environment determination table 601 in FIG. As the external environment condition value to be applied, those in which “environment type” is “(i) use environment”, “environment condition” is “(1) contract form”, and “option” is “commercial use” are applicable. Therefore, the risk evaluation value totaling unit 205 uses the CPU 911 to extract the row data of the environment / failure determination table 501 in FIG. 12 using the external environment condition value (“option” of “commercial use”) as a key. Corresponding row data are “O”, “O”, “O”, “O”, “O”, “O” from the left. Therefore, the risk evaluation value totaling unit 205 is the first row of the risk / failure determination table 701 in FIG. 14, and “risk” is “license risk” and “evaluation target” is “infringement of intellectual property rights”. From the left, “1” (= 1 point × 1 time), “1” (= 1 point × 1 time), “1” (= 1 point × 1 time), “1” (= 1 point × 1) 1), “1” (= 1 point × 1 time), and “1” (= 1 point × 1 time) are set and stored in the magnetic disk device 920.
(2) Out of the items for which “△” is set in the risk / environment determination table 601 in FIG. 13, the external environment corresponding to the item in which “risk” is “quality risk” and “evaluation target” is “use form” As the condition value, “environment type” is “(i) use environment”, “environment condition” is “(2) use form”, and “option” is “single use”. Therefore, the risk evaluation value totaling unit 205 extracts the row data of the environment / failure determination table 501 in FIG. 12 by the CPU 911 using the external environment condition value (“option” of “single use”) as a key. Corresponding row data are “O”, “O”, “O”, no mark, “O”, and no mark from the left. Therefore, the risk evaluation value totaling unit 205 sets the row data in the second row of the risk / failure determination table 701 in FIG. 14 where “risk” is “quality risk” and “evaluation target” is “usage”. From the left, “3” (= 1 point × 3 times), “3” (= 1 point × 3 times), “3” (= 1 point × 3 times), “6” (= 2 points × 3 times) , “3” (= 1 point × 3 times) and “6” (= 2 points × 3 times) are set and stored in the magnetic disk device 920.
(3) Similar to (2) above, the risk evaluation value totaling unit 205 is the third row of the risk / failure determination table 701 in FIG. 14, where “risk” is “quality risk” and “evaluation target” is From the left, “3” (= 1 point × 3 times), “3” (= 1 point × 3 times), “3” (= 1 point × 3 times), “ “6” (= 2 points × 3 times), “3” (= 1 point × 3 times), and “6” (= 2 points × 3 times) are set and stored in the magnetic disk device 920.
(4) As in the above (2), the risk evaluation value totaling unit 205 is the fourth row of the risk / failure determination table 701 in FIG. 14, and “risk” is “quality risk” and “evaluation target” is From the left, “3” (= 1 point × 3 times), “3” (= 1 point × 3 times), “3” (= 1 point × 3 times), “6” “=” (= 2 points × 3 times), “3” (= 1 point × 3 times), and “6” (= 2 points × 3 times) are set and stored in the magnetic disk device 920.
(5) Out of the items for which “△” is set in the risk / environment determination table 601 in FIG. 13, the external environment corresponding to the items in which “risk” is “technical risk” and “evaluation target” is “use form” The condition value corresponds to “environment type” of “(i) use environment”, “environment condition” of “(2) use mode”, and “option” of “joint use”. Therefore, the risk evaluation value totaling unit 205 extracts the row data of the environment / failure determination table 501 in FIG. 12 by the CPU 911 using the external environment condition value (“option” of “shared use”) as a key. Corresponding row data are “O”, no mark, “O”, no mark, “O”, no mark from the left. For this reason, the risk evaluation value totaling unit 205 sets the row data of the “risk” as “technical risk” and the “evaluation target” as “usage” in the fifth row of the risk / failure determination table 701 in FIG. From the left, “2” (= 1 point × 2 times), “4” (= 2 points × 2 times), “2” (= 1 point × 2 times), “4” (= 2 points × 2 times) , “2” (= 1 point × 2 times) and “4” (= 2 points × 2 times) are set and stored in the magnetic disk device 920.
(6) Of the items for which “△” is set in the risk / environment determination table 601 in FIG. 13, the external environment corresponding to the item “risk” is “technical risk” and “evaluation target” is “use form” As the condition value, “environment type” is “(ii) terminal environment”, “environment condition” is “(1) number of connected terminals”, and “option” is “1,000 or more and less than 5,000” or “ Applicable to “5,000 or more”. Therefore, the risk evaluation value totaling unit 205 uses the one of the external environmental condition values (“option” of “1,000 or more and less than 5,000”) as a key in the row of the environment / failure determination table 501 in FIG. Data is extracted by the CPU 911. Corresponding line data are unmarked, unmarked, unmarked, unmarked, unmarked, and unmarked from the left. Therefore, the risk evaluation value totaling unit 205 is the sixth row of the risk / failure determination table 701 in FIG. 14, where “risk” is “technical risk”, “evaluation target” is “usage”, and “option” is From the left, “4” (= 2 points × 2 times), “4” (= 2 points × 2 times), “4” (= 2) Point × 2), “4” (= 2 points × 2 times), “4” (= 2 points × 2 times), and “4” (= 2 points × 2 times) are set in the magnetic disk device 920. Remember.
(7) The risk evaluation value totaling unit 205 performs the same process on the other of the external environmental condition values in (6) above ("option" of "5,000 or more"), and determines the risk / failure determination in FIG. In the seventh row of the table 701, “4” from the left in the row data in which “risk” is “technical risk”, “evaluation target” is “usage”, and “option” is “5,000 or more”. "(= 2 points x 2 times)," 4 "(= 2 points x 2 times)," 4 "(= 2 points x 2 times)," 4 "(= 2 points x 2 times)," 4 "( = 2 points × 2 times) and “4” (= 2 points × 2 times) are set and stored in the magnetic disk device 920.
(8) As in the above (3), the risk evaluation value totaling unit 205 is the eighth row of the risk / failure determination table 701 in FIG. 14, and “risk” is “technical risk” and “evaluation target” is From the left, “2” (= 1 point × 2 times), “4” (= 2 points × 2 times), “2” (= 1 point × 2 times), “4” “= 2” (= 2 points × 2 times), “2” (= 1 point × 2 times), and “4” (= 2 points × 2 times) are set and stored in the magnetic disk device 920.
(9) The risk evaluation value totaling unit 205 totalizes the score set in the above (1) to (8) by the CPU 911 for each combination of Apache version and “failure type”.
(A) Column data in which the version of Apache is “2.0” and “failure type” is “(A) terminal freeze” are added in order from the top, 1 point + 3 points + 3 points + 3 points + 2 points + 4 points + 4 Points + 2 points = 22 points. On the other hand, when the version of Apache is “2.2”, 1 point + 3 points + 3 points + 3 points + 4 points + 4 points + 4 points + 4 points = 26 points.
(B) Column data in which the version of Apache is “2.0” and “failure type” is “(B) server error” is added in order from the top, 1 point + 3 points + 3 points + 3 points + 2 points + 4 points + 4 Points + 2 points = 22 points. On the other hand, when the version of Apache is “2.2”, 1 point + 6 points + 6 points + 6 points + 4 points + 4 points + 4 points + 4 points = 35 points.
(C) Column data in which the version of Apache is “2.0” and “failure type” is “(C) screen white display” are added in order from the top, 1 point + 3 points + 3 points + 3 points + 2 points + 4 points +4 points + 2 points = 22 points. On the other hand, when the version of Apache is “2.2”, 1 point + 6 points + 6 points + 6 points + 4 points + 4 points + 4 points + 4 points = 35 points.
(10) The risk evaluation value totaling unit 205 further totalizes the score totaled in the above (9) by the CPU 911 for each version of Apache. When the version of Apache is “2.0”, adding in order from the left gives 22 points + 22 points + 22 points = 66 points. On the other hand, when the version of Apache is “2.2”, 26 points + 35 points + 35 points = 96 points.

  In step S106, the risk evaluation value selection unit 206 uses the CPU 911 to obtain a lower score, that is, 66 points (<99 points) among the points calculated for each version of Apache by the risk evaluation value aggregation unit 205 in step S105. select.

  In step S107, the recommended value output unit 207 displays the Apache version corresponding to the score of the risk evaluation value selected by the risk evaluation value selection unit 206 in step S106, that is, “2.0” as a tuning value. Output to.

  In step S <b> 108, the recommended value output unit 207 determines whether the CPU 911 has completed tuning of all environment variables related to the tab setting file (Apache / httpd.conf) selected on the operation screen 401. In this example, it is assumed that “no” is determined. Therefore, the next environment variable tuning is executed from step S105.

  Next, a second example is shown. Here, if the second example is a process performed after the first example (a process after “No” is determined in step S108 of the first example), the following steps S101 to S104 are performed. That is, batch processing is performed in steps S101 to S104 in the first example.

  In the second example, in step S101 (batch processing with the first example is possible), the failure storage unit 201 determines that the Apache server httpd. The OSS failure information 114 related to Timeout set in the conf is acquired from the Internet and stored in the magnetic disk device 920.

  In step S102 (batch processing with the first example is possible), the default value storage unit 203 sets the default value of Timeout as “300 seconds” in advance or at httpd. It is acquired from conf and stored in the magnetic disk device 920. The default value storage unit 203 sets the default value to httpd. When acquiring from conf, the default value is httpd. The value currently set to Timeout in conf.

  In step S103 (collective processing with the first example is possible), the risk evaluation value storage unit 202 stores the environment / failure determination table 502 shown in FIG. 15 in the magnetic disk device 920 as OSS failure risk information. This environment / failure determination table 502 is based on Apache httpd. The score of the risk evaluation value corresponding to each of “300 seconds” (default value stored in step S102) and “60 seconds” that can be set as the value of Timeout in the conf is expressed as an external environmental condition value (vertical axis). This is shown for each combination of the “failure type” (horizontal axis) of the failure. Similar to the first example, in the environment / failure determination table 502, for each combination of the external environmental condition value corresponding to each item, the “failure type” of failure, and the value of Timeout, “◯” or “ “X” is set or nothing is set (no mark). As in the first example, the risk is quantitatively evaluated with “◯” as 1 point, “X” as 3 points, and unmarked as 2 points.

  In step S104 (batch processing with the first example is possible), the environmental candidate value input unit 204 assumes the current external environmental condition value and the external environmental condition assumed when the future document management system is expanded. Value input is accepted from the keyboard 902 or mouse 903 and stored in the magnetic disk device 920 as the risk / environment determination table 601 shown in FIG. The environment candidate value input unit 204 is the same as in the first example.

  In step S105, the risk evaluation value totaling unit 205 includes the environment / failure determination table 502 stored in the risk evaluation value storage unit 202 in step S104 and the risk / environment determination table input by the environment candidate value input unit 204 in step S102. 601 is read from the magnetic disk device 920. Similarly to the first example, the risk evaluation value totaling unit 205 uses the external environment condition value corresponding to the item for which “Δ” is set in the risk / environment determination table 601 as a key, and the environment / failure determination table 502. Are extracted by the CPU 911, and each item of the extracted row data is weighted. Then, the risk evaluation value totaling unit 205 inserts each row data into the risk / failure determination table 702 shown in FIG. 16 and stores it in the magnetic disk device 920.

Hereinafter, the risk evaluation value aggregation processing in step S105 will be described for each row of the risk / failure determination table 702 in FIG.
(1) The first row of the risk / failure determination table 702 in FIG. 16 is the same as in the first example.
(2) The second row of the risk / failure determination table 702 in FIG. 16 is the same as in the first example.
(3) Out of the items for which “△” is set in the risk / environment determination table 601 in FIG. 13, “risk” is “quality risk” and “evaluation target” is “number of connected terminals”. As environmental condition values, “environment type” is “(ii) terminal environment”, “environment condition” is “(1) number of connected terminals”, and “option” is “300 or more and less than 1,000”. Is applicable. Therefore, the risk evaluation value totaling unit 205 uses the CPU 911 to store the row data of the environment / failure determination table 502 in FIG. 15 using the external environment condition value (“option” of “300 or more and less than 1,000”) as a key. Extract. The corresponding row data is “×”, “O”, “×”, “O”, “×”, “O” from the left. Therefore, the risk evaluation value totaling unit 205 is the third row of the risk / failure determination table 702 in FIG. 16, in which “risk” is “quality risk” and “evaluation target” is “number of connected terminals”. From the left, “9” (= 3 points × 3 times), “3” (= 1 point × 3 times), “9” (= 3 points × 3 times), “3” (= 1 point × 3 times) ), “9” (= 3 points × 3 times), and “3” (= 1 point × 3 times) are set and stored in the magnetic disk device 920.
(4) As in (3) above, the risk evaluation value totaling unit 205 is the fourth row of the risk / failure determination table 702 in FIG. 16, and “risk” is “quality risk” and “evaluation target” is From the left, “9” (= 3 points × 3 times), “3” (= 1 point × 3 times), “9” (= 3 points × 3 times), “3” “=” (= 1 point × 3 times), “9” (= 3 points × 3 times), and “3” (= 1 point × 3 times) are set and stored in the magnetic disk device 920.
(5) The fifth row of the risk / failure determination table 702 in FIG. 16 is the same as in the first example.
(6) Out of the items for which “△” is set in the risk / environment determination table 601 in FIG. 13, “risk” is “technical risk” and “evaluation target” is “items connected” As environmental condition values, “environment type” is “(ii) terminal environment”, “environment condition” is “(1) number of connected terminals”, and “option” is “1,000 or more and less than 5,000”. This is true. Therefore, the risk evaluation value totaling unit 205 uses the external environment condition value (“option” of “1,000 or more and less than 5,000”) as a key to retrieve the row data of the environment / failure determination table 502 of FIG. Extracted by CPU 911. The corresponding row data is unmarked from the left, “◯”, unmarked, “◯”, unmarked, “◯”. Therefore, the risk evaluation value totaling unit 205 is the sixth row of the risk / failure determination table 702 in FIG. 16, in which “risk” is “technical risk” and “evaluation target” is “number of connected terminals”. From the left, “4” (= 2 points × 2 times), “2” (= 1 point × 2 times), “4” (= 2 points × 2 times), “2” (= 1 point × 2 times) ), “4” (= 2 points × 2 times), and “2” (= 1 point × 2 times) are set and stored in the magnetic disk device 920.
(7) The seventh row of the risk / failure determination table 702 in FIG. 16 is the same as in the first example.
(8) The eighth line of the risk / failure determination table 702 in FIG. 16 is the same as in the first example.
(9) The risk evaluation value totaling unit 205 totalizes the score set in the above (1) to (8) by the CPU 911 for each combination of the Timeout value and the “failure type”.
(A) Column data whose Timeout value is “300 seconds” and “failure type” is “(A) terminal freeze” are added in order from the top: 1 point + 3 points + 9 points + 9 points + 2 points + 4 points + 4 points +2 points = 34 points. On the other hand, when the value of Timeout is “60 seconds”, 1 point + 3 points + 3 points + 3 points + 4 points + 2 points + 4 points + 4 points = 24 points.
(B) Column data in which the value of Timeout is “300 seconds” and the “failure type” is “(B) server error” is added in order from the top, 1 point + 3 points + 9 points + 9 points + 2 points + 4 points + 4 points +2 points = 34 points. On the other hand, when the value of Timeout is “60 seconds”, 1 point + 6 points + 3 points + 3 points + 4 points + 2 points + 4 points + 4 points = 27 points.
(C) Column data in which the value of Timeout is “300 seconds” and the “failure type” is “(C) screen white display” is added in order from the top, 1 point + 3 points + 9 points + 9 points + 2 points + 4 points + 4 Points + 2 points = 34 points. On the other hand, when the value of Timeout is “60 seconds”, 1 point + 6 points + 3 points + 3 points + 4 points + 2 points + 4 points + 4 points = 27 points.
(10) The risk evaluation value totaling unit 205 further totalizes the score totaled in the above (9) by the CPU 911 for each value of Timeout. When the value of Timeout is “300 seconds”, adding in order from the left gives 34 points + 34 points + 34 points = 102 points. On the other hand, when the value of Timeout is “60 seconds”, 24 points + 27 points + 27 points = 78 points.

  In step S106, the risk evaluation value selection unit 206 uses the CPU 911 to assign a lower score, that is, 78 points (<102 points), out of the points totaled for each Timeout value by the risk evaluation value aggregation unit 205 in step S105. select.

  In step S107, the recommended value output unit 207 sends the value of Timeout corresponding to the score of the risk evaluation value selected by the risk evaluation value selection unit 206 in step S106, that is, “60 seconds” to the display device 901 as a tuning value. Output.

  In step S <b> 108, the recommended value output unit 207 determines whether the CPU 911 has completed tuning of all environment variables related to the tab setting file (Apache / httpd.conf) selected on the operation screen 401. In this example, it is assumed that “yes” is determined. Therefore, the tuning process ends.

  As described above, in this embodiment, the OSS automatic tuning apparatus 200 uses the OSS failure risk information corresponding to the external environmental conditions of the business system 104 to determine the license aspect (risk of intellectual property infringement), quality OSS environment variable values that can be changed are extracted in order to lower the risk of the aspect (effectiveness as a countermeasure against failure) and the technical aspect (scalability). As a result, various troubles during operation of the business system 104 can be prevented. In the above two examples, the OSS automatic tuning apparatus 200 uses the Apache version and httpd. Although the tuning value of the Timeout value set by conf has been determined, according to the present embodiment, other various tuning values of environment variables illustrated in FIG. 17 can be determined.
