In this case, not only a case where a new intranet system is introduced, but also a case where an existing system is extended to cooperate with the intranet system. Also, the functions and performance required for the intranet system differ for each user. Therefore, when introducing an intranet system, it is necessary to consider the actual situation of each user.

[0003] More specifically, it is possible to estimate the performance of a server computer and the required number of servers in an intranet system, taking into account cases where tasks are concentrated, such as daily processing, monthly processing, and term-end processing. Required.

[0004]

However, since the components of the intranet system are new technologies and products, what kind of system should be constructed for users who do not have the know-how on the intranet system. It was very difficult to judge this, and it was necessary to consider the required specifications by trial and error.

[0005] Even if the outline of the intranet system to be constructed is determined, it is merely a logical image. In this case, the client terminal,
It is necessary to expand the logical configuration to the physical configuration of an intranet system composed of server computers, networks, etc. In such a mapping from logical to physical, for example, what kind of network configuration should be adopted and what kind of system It is very difficult to accurately grasp the actual physical configuration such as the configuration.

Furthermore, since various knowledge is required when constructing an actual system such as a load distribution configuration and a cluster configuration, it takes a lot of time and manpower to construct a system that meets the requirements. .

The present invention has been made in view of the above circumstances, and by utilizing a mechanism for presenting various system configurations using models, it is possible to easily specify an optimal system that meets the conditions simply by specifying conditions. It is an object to provide a computer design support system and a computer design support method that can be constructed.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a computer design support system for supporting the design of a computer system, comprising: a plurality of models for systematically indicating types of system configurations; A client terminal that stores a network configuration that can be used in each model, a database that stores system configuration information including at least information for defining the scale and performance of the system, and a deployment support screen for supporting the configuration of the target system.

In this computer design support system, system construction information required for system construction, such as system model, network configuration, scale, performance, etc., is stored in advance in a database as know-how information. By specifying the model, network configuration, scale, and performance conditions individually, the optimal system configuration that meets the user's specified conditions is determined based on the system configuration information stored in the database.
It is automatically presented on the introduction support screen. Therefore,
It is possible to provide consultation on system introduction through dialogue with the user without knowing how to introduce the system. In particular, the model is obtained by systematically classifying a large number of system configuration types based on various know-how, so even if the user does not have knowledge of each of the many system configuration types, the model can be selected only by selecting the model to be used. It is possible to construct an appropriate system based on the system configuration corresponding to.

With the provision, a highly reliable system scale or performance can be selected in consideration of the load status of the existing system.

In this case, the load information of the already operated existing computer system is converted into the existing information, taking into consideration the case where some of a plurality of tasks operated by the existing system are migrated to the target system. Collected for each type of business running on the computer system, based on the business type to be performed on the installation target system specified on the installation support screen of the client terminal, and the load information on the existing computer system related to that business type It is preferable to predict a system scale or performance suitable for the system to be introduced.

Furthermore, a configuration is adopted in which a system introduction price for a system configuration corresponding to the model, network configuration, scale, and performance of the system to be introduced is calculated, and the calculated system introduction price is presented on an introduction support screen. Thereby, a more convenient support system can be realized.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the overall configuration of a computer design support system according to an embodiment of the present invention. This computer design support system is for providing system design support for an intranet system, and is realized using a client-server type computer system. In this computer system, as shown, a server computer 100
And a client terminal 110 composed of, for example, a personal computer, are connected to each other via a computer network 120 such as a LAN.

The server computer 100 and the client terminal 110 include a CPU (not shown), a main memory,
A magnetic disk device as a storage device and an input / output device having an input unit such as a keyboard and a mouse and a display unit such as a display are connected.

The server computer 100 is provided with a Web server 101, an introduction support applet 102, a know-how database 103, and an introduction support content 104 as a functional configuration for supporting system design as shown in the figure.

The Web server 101 is a client terminal 1
10 for providing services such as providing contents in response to a request from the Web browser 111 operating on the Web browser 10.
2 URL (Unified Resource Loc)
Attor), the introduction support applet 102 corresponding thereto is activated and executed, and the introduction support content output from the introduction support applet 102 is returned to the Web browser 111.

The installation support applet 102 is called from the Web browser 111, and the Web server 101
It is downloaded to the b browser 111, activated, and executed.
The operation of the introduction support applet 102 is performed by the Web browser 1
The user interactively performs operations using a mouse or the like through the screen 11. When the user selects a tool button of the introduction support applet 102 on the screen, the know-how corresponding to the tool button is retrieved from the know-how database 103, and once stored in the introduction support content 104, the Web browser 1
Since a pull-down menu is displayed on the screen 11, the user selects an optimum one from the pull-down menu. Then, the introduction support applet 102 retrieves, for example, a system model diagram from the know-how database 103 and displays the system model diagram on the screen of the Web browser 111. Thereafter, each time the operation is performed in this manner, the search of the know-how database 103 is performed, and the relevant know-how is displayed, the user selects, and the result is displayed.

The know-how database 103 of the server computer 100 includes a model indicating the type of system configuration of the intranet system, the network configuration, the system scale, the processing capabilities of the client terminal and the server computer (CPU speed, memory size, disk capacity, etc.). ), Operating system, model, and other information necessary for system construction are accumulated as know-how.

Also, tool buttons (model, network configuration, load distribution,
Information corresponding to clusters, WANs, directories, security, application scale, client scale, server scale, etc.) is also accumulated in the know-how database 103 as know-how. These know-how can be accumulated,
You can search, display, change, etc. The know-how accumulation and the change are performed by the know-how accumulation tool 105.

Further, the know-how database 103 includes the existing business processing computer 1 already operated.
The load information regarding 30 can also be accumulated through the know-how accumulation tool 105. This is so that the system performance and scale required for the intranet system to be introduced can be predicted based on the load information on the existing business processing computer 130.

That is, on the business processing computer 130, the load status of the business processing computer 130 is periodically collected by the collection tool, and the collected information is recorded in the log file 132 as load information. Then, the load information of the log file 132 is accumulated in the know-how database 103 through the know-how accumulation tool 105. The collection of the load status is performed individually for each task type running on the task processing computer 130. Specifically, processes executed on the job processing computer 130 are classified by job type, and the CPU usage rate, disk usage amount, memory usage amount, and the like for each of the processes are collected and accumulated for each job type. Is performed.

In the introduction support content 104 of the server computer 100, the user enters the introduction support applet 102.
The intranet system configuration as a result of the interactive construction is stored in the Web format by the introduction support applet 102. Later, the user can refer to or change the intranet system configuration that has been constructed and simulated by specifying the URL.

The know-how accumulation tool 105 of the server computer 100 is a tool for making changes in the data of the know-how database 103 based on the know-how of the user and for accumulating new know-how. This is for accumulating know-how obtained by so-called user learning.

The models stored as a part of the know-how data in the know-how database 103 are obtained by systematically classifying a number of system configuration types related to the intranet system. Information on a specific system configuration such as a network configuration and load distribution is stored in the know-how database 103 as know-how data. In order to be able to graphically display the system configuration corresponding to the model, network configuration, load distribution, cluster, etc. selected and designated by the user on the screen of the Web browser 111, the know-how database 103 includes a system configuration for each model. , A plurality of system configuration diagrams corresponding to respective network configurations usable in each model, and a system configuration diagram corresponding to each load distribution configuration.

(Model) The classification of models used in this embodiment will be described below. Here, the model of the existing system cooperation is mainly presented, but basically the same is not changed in the newly introduced system.

FIGS. 2 and 3 show typical examples of the three-layer model.
The Web browser processes only HTML and is suitable for relatively small-scale system construction. The meaning of the three layers is that it is composed of three layers: a Web browser 11, a Web server 12, and a data source 13 meaning HTML data, a small database, an existing system, a core database, and the like. In the case of a newly introduced system, the data source layer is newly constructed. FIG. 2 shows the following four models.

(1) Model 1 This is a basic model for information sharing.
This model is used for information transmission and search. In this model, cooperation with the business system is not performed. The interface between the Web browser and the Web server is HTTP (Hyper Text), which is one of the Internet protocols.
Transfer Protocol).

(2) Model 2 This is a model for small-scale database access, and is a non-online transaction process (OLTP: Online T).
ransaction processing). This model is a C called from the HTML of the Web browser.
This is a basic data access model in which a GI (Common Gateway Interface) application accesses a database. The database interface is ODBC (Open
Use Data Base Connectivity).

(3) Model 3 This is a model for cooperating with existing systems, and is a relatively small-scale and non-OLTP model. H in Web browser
By processing only TML and describing the business application in Java Servlet on the Web server, a high-performance system with higher expandability and portability as compared to the model 2 CGI application can be constructed. The existing system linkage interface includes JNI (Java Nat
ive Interface) and JDBC (Java Data Base Connectivity) for the database interface. However, in this model, Servlet is HTML
Must be dynamically generated internally and returned to the Web browser, so the presentation process is embedded and must be recompiled and relinked each time it is modified, resulting in maintainability. Falls.

(4) Model 4 This is a model for linking existing systems, and is a relatively small-scale and non-OLTP model. H in Web browser
Only the TML is processed, and the business application is executed on the Web server by Java Servlet and JSP (Java).
(ServerPages), it is possible to construct a system having better maintainability than the model 3. This is because Servlet is business processing logic,
This is because JSPs can independently take on the role of presentation that dynamically generates HTML and returns it to the Web browser. In other words, when only the screen display format is improved without changing the business processing logic, only the JSP needs to be modified, so that it can be said that the maintainability is better than the case where only the Servlet is used as in the model 3. The existing system linkage interface includes JNI
(Java Native Interface) and JDBC (Java Data Base Connectivity) for the database interface.
Use

The models 5 and 6 shown in FIG. 3 correspond to the HT of the web browser of the models 3 and 4 in FIG. 1, respectively.
ML is replaced with Applet. These two
The two models are different from the models 3 and 4 in FIG.
A client terminal with a high processing capability is required for executing the pplet.

FIG. 4 shows a typical example of the four-layer model based on the server side Java, which is suitable for constructing a medium- to large-scale system that cooperates with an existing system or a backbone database. The meaning of the four layers is Web browser 17, Web
b, a web application server 19 that executes business processing logic with high reliability and high performance, and a data source 20 that means an existing system, a core database, and the like. An advantage of the Java-based model is that a system that runs on various operating systems can be constructed. Furthermore, UNIX (registered trademark), Windows (registered trademark), Linux
A system can be realized by combining different platforms such as (registered trademark). The client terminal is We
Since only the HTML is processed by the b-browser, a high-performance one is not required. FIG. 4 shows the following four models.

(7) Model 7 This is a model for linking existing systems, and is a medium-scale OLT.
A model for P. This model is from HTML to W
Call Servlet of eb server, Servlet
t invokes EJB (Enterprise Java Beans) by an EJB-specific interface. EJB is a common logic from a huge amount of business processing logic.
A set of objects described in va, which is managed and executed by an EJB engine on a Web application server. The Web application server has a transaction processing function based on Java, and EJB is executed with high reliability. Therefore, this model is highly loaded OL
Suitable for TP. EJB uses JNI / JDBC for interfacing with existing systems and backbone databases. This model must allow the Web server to efficiently execute Servlets. That is, this model is effective when such a Web server is selected.
By the way, there are various Web servers, and some do not have a Java execution environment.

(8) Model 8 This is a model for linking existing systems, and is a medium-sized OLT.
A model for P. This is the same as Model 7, except that Servlet is executed on the Web application server. Since the Web application server is equipped with a development environment, an execution environment, and an operation environment, development cost, maintainability, system expandability, reliability, and the like are superior to executing Servlet on the Web server. This model is such a Web
It can be said that this model takes full advantage of the features of the application server. This model calls Servlet of Web application server from HTML, and S
This is a model in which an servlet calls an EJB to execute business processing logic on a Web application server. The EJB interface uses a dedicated EJB. In the model 7, the Servlet is executed by the Web server. However, when the processing capacity of the Web server is low, the Servlet is
It needs to be executed by the web application server.

(9) Model 9 Although this model 9 is similar to the model 7,
The difference is that the vlet is separated from the JSP of the presentation. Web browser HTML is Ser
vlet, and Servlet calls EJB of the Web application server. The result is Servl
et receives from EJB and passes to JSP, JSP is HTM
L is generated and returned to the Web browser. This model 9
Web server is suitable for medium-sized OLTP to execute Servlet and JSP.

(10) Model 10 This is a model in which Servlet-JSP of model 9 is migrated from a Web server to a Web application server, and the maintenance cost is small. JSP corresponding to the presentation and Serv which is business processing logic
This is because the let can be separately maintained and managed. This model 9 is based on the Web application server
It is suitable for large-scale OLTP to execute et and JSP.

FIG. 5 shows five of the four-layer models. The difference from FIG. 4 is that the applet is executed in the Web browser. Therefore, the processing capability of the client terminal must be higher than the model shown in FIG.

(11) Model 11 This is a model for linking existing systems, and is a medium-sized OLT.
A model for P. This model is Java Ap
EJM (Enterprise Java Beans) from plet
I (Remote Method Invocation) and CORBA (Common
IIOP (Internet Inter-O) which is an Internet protocol of the Object Request Broker Architecture
Called by the interface called RB Protocol, ORB: Object Request Broker.

(12) Model 12 This is a model for linking existing systems, and is a medium-sized OLT.
A model for P. Apple of Web browser
In this model, t calls Servlet on the Web server, and the Servlet calls EJB to execute the business processing logic on the Web application server. Similar to model 7 in FIG.
It is different based on et.

(13) Model 13 This is the same as Model 12, but differs from Serv.
Let is to be executed on the Web application server. This model is suitable for large-scale OLTP. Similar to Model 8 in FIG. 4, but different in Applet base.

(14) Model 14 This is a model in which JSP is applied to model 12. The maintenance cost is smaller than that of the model 12. JSP corresponding to presentation and S which is business processing logic
This is because servlets can be separately maintained and managed.
This model is also similar to model 9 in FIG.
The difference is in the plet base.

(15) Model 15 This is a model in which the servlet of the model 14 has been transferred to the Web application server. This is the most balanced model for large-scale OLTP among the eight models described so far. This model is also similar to the model 10 of FIG. 4, except that it is Applet-based.

FIG. 6 shows another example of the four-layer model Mi
It is based on the product of Microsoft Corporation, and is suitable for small- to medium-scale system construction that cooperates with existing systems and core databases. The meaning of the four layers is COM + (Common Ob) that executes the Web browser 25, the Web server 26, and the business processing logic with high reliability and high performance.
project Model +) 27, and existing systems,
4 of data source 28 which means backbone database etc.
It is composed of three layers. The merit of this model is that it is possible to build a system that operates only with products provided by one company. Construction is easier than combining different platforms. FIG. 6 shows the following one model.

(16) Model 16 This is a model having the same configuration as the model 9 in FIG. This model is suitable for small to medium sized OLTP. Web browsers are DHTML (Dynamic HTML), VBscript (Vi
sual Basic script), Jscript (Java script)
Enables ASP (Active Server Page) on Web server
s) call. ASP has a function equivalent to that of JSP and performs presentation processing. The interface between ASP and COM + is DCOM (Distributed COM), and the interface between COM + and existing systems and databases is ADO (Active X Data Objects), OD
BC / XA (XA interface is an X between the OLTP monitor and the DBMS (Data Base Management System).
/ Open unified interface standard), and OLE
Use DB. COM + includes MTS (Microsoft Transaction Server) that executes transaction processing
And a function such as MQ (MessageQueue) that provides an asynchronous communication function.

As described above, in the present embodiment, the intra network system is classified into 16 models according to its scale and application, and a system can be constructed based on each model.

Further, as for the load distribution configuration, some suitable configuration examples relating to a typical load distribution system are determined in advance in association with a model and a network configuration, and are stored in the know-how database 103. The know-how data is a type of rule information, and an optimum system that matches the condition is determined based on the condition specified by the user and the know-how data.

(Collection of Load Information) FIG. 7 shows an example of a format of load information output by the collection tool 131. As illustrated, the load information is recorded in the log file 132 as a set of a task type, a process ID, a collection time, a CPU usage rate, a memory usage amount, and a disk usage amount. By analyzing this, for example, the state of transition of the CPU usage rate as shown in FIG. 8 can be obtained for each task type.

(Introduction Supporting Process) Next, a system introduction supporting process performed by the computer design support system will be described with reference to flowcharts of FIGS.

First, a download request for the introduction support applet 102 is sent from the Web browser 111 of the client terminal 110 to the Web server 1 of the server computer 100.
01 (step S111). When the web browser 111 executes the introduction support applet 102 downloaded from the web server 101, the initial screen of FIG. 12 is displayed on the screen of the web browser 111 (step S1112).

On this initial screen, a “model” button for selecting a model, a “network configuration” button for selecting a network configuration, a “load distribution” button for selecting a load distribution configuration, and a cluster configuration are selected. In addition to a “cluster” button for performing the above operations, various tool buttons are provided for making selections regarding WAN connection, directory service, security, application scale, and the like. Furthermore, on the initial screen, a “client scale” button for selecting a client scale, a “server scale” button for selecting a server scale, a “price” button for presenting a system introduction price during simulation, An “existing system cooperation” button for selecting and inputting various information necessary for cooperation with the existing business processing computer 130 is also provided. Hereinafter, a processing flow performed in this screen and in a conversation format will be described.

First, when the "model" button is selected by the user, a pull-down menu for selecting the above 16 models is displayed as shown in FIG. 13 (step S113). In this case, first, the menu items of “new introduction” and “existing system cooperation” are displayed on the menu, and then, for example, when “existing system cooperation” is selected, the above-mentioned 16 types of models that can be used in existing system cooperation and A brief description of the model is displayed. This is basically the same when “new introduction” is selected. In FIG. 13, model 1
5 shows a case where 5 is selected. Information that the model 15 has been selected is sent to the server computer 100. Then, the system configuration diagram of the model 15 is acquired from the know-how database 103, and is sent from the server computer 100 to the Web browser 111, so that the system configuration diagram corresponding to the model 15 is displayed as shown in FIG. 14 (step S114). ).

Next, when the "network configuration" button is selected by the user as shown in FIG. 15, a list of available network configurations is displayed on a menu, and the network configuration to be used is selected on the menu (FIG. 15). Step S115). Here, it is assumed that “independent LAN segment” is selected as the network configuration. Information that the independent LAN segment has been selected is sent to the server computer 100. Then, the network configuration diagram of the independent segment corresponding to the model 15 is acquired from the know-how database 103, and is sent from the server computer 100 to the Web browser 111, so that it is displayed as shown in FIG. 16 (step S11).
6).

Next, when the "load distribution" button is selected by the user as shown in FIG. 17, a list of available load distribution systems is displayed in a menu, and the selection of the load distribution system to be used is performed on the menu. (Step S
117). Here, it is assumed that “medium-scale + use of load distribution device” is selected as the configuration of the load distribution system. Information that “medium scale + use of load balancer” is selected is sent to server computer 100. Then, a diagram in which the load distribution device is added to the network configuration of the model 15 is transmitted from the server computer 100 to the Web browser 1.
11 is displayed as shown in FIG. 18 (step S118).

Next, as shown in FIG.
b When the "server size" button is selected after the server computer on which the application server is mounted is clicked, a list for selecting the server size (the number of servers) is displayed in a menu, and the server size is selected on the menu. Is performed (step S119). here,
It is assumed that “10 large-scale servers” has been selected.
Information that “ten large-scale servers” has been selected is sent to server computer 100. Then, a plurality of server computers equipped with a Web application server are displayed on the screen as shown in FIG. 20 (step S120).

Next, processing for determining the model and performance of the server computer is performed (step S121). That is, as shown in FIG. 21, the properties of the server computer are displayed in a menu by right-clicking the mouse, and an operating system (OS), a CPU speed (clock frequency), a memory size, a disk capacity, and the like to be used are selected by the user. The selected information is also sent to the server computer 100. If the button of “existing system cooperation” is selected by the user, the processing of step S121 is executed according to the processing procedure shown in the flowchart of FIG.

For setting the CPU speed, for example, a basic CPU speed to be used is automatically selected based on the know-how data stored in the know-how database 103 (step S201). Next, the CPU usage rate in the existing system is determined based on the load information of the existing system (step S202). For example, when the average CPU usage rate in the existing system is lower than 70% (NO in step S203), the basic CPU speed is determined as it is as the recommended CPU speed, and is displayed on the screen (step S204). If the CPU usage rate is lower than 80% (N in step S205)
O), the clock frequency corresponding to the basic CPU speed is +
The value increased by 100 MHz is determined as the recommended CPU speed to be used, and is displayed on the screen (step S20).
6) If the CPU usage rate is lower than 90% (NO in step S207), a value obtained by increasing the clock frequency corresponding to the basic CPU speed by +200 MHz is determined as the recommended CPU speed to be used, and this is determined. The screen is displayed (step S208). Of course, the determined recommended CPU speed can be changed by a user operation. If no changes are made, the recommended CP presented
U speed will be determined. Similarly, optimal values for disk capacity and memory size are predicted based on the disk usage and memory usage of the existing system.
It is presented.

If the user selects the type of business to be executed in the intranet system by selecting the button of "existing system cooperation", the processing procedure of FIG. 11 is executed.

That is, when a user selects a business type to be executed in the intranet system (step S211), first, the know-how database 103 is obtained.
Then, based on the load information accumulated for each task type, only the CPU usage rate of each of the selected tasks is added, thereby determining the CPU usage rate of the entire selected task (step S212). If the CPU usage rate is lower than 70% (NO in step S213), the basic CPU speed is determined as it is as the recommended CPU speed and is displayed on the screen (step S21).
4). If the CPU usage rate is lower than 80% (NO in step S215), a value obtained by increasing the clock frequency corresponding to the basic CPU speed by +100 MHz is determined as the recommended CPU speed to be used, and is displayed on the screen. (Step S216), and the CPU usage rate is 90
% (NO in step S217), the clock frequency corresponding to the basic CPU speed is + 200M
The value increased by Hz is determined as the recommended CPU speed to be used, and is displayed on the screen (step S218).
Similarly, the optimum values of the disk capacity and the memory size are predicted and determined based on the disk usage and the memory usage of each of the selected tasks.

Further, not only the server performance but also the system scale such as the number of servers may be predicted and presented based on the load information of the existing system.

Next, as shown in FIG.
When the “Cluster” button is selected after a plurality of server computers with server applications are clicked, a menu for selecting one of the cluster configuration / single configuration is displayed, and the cluster configuration / The selection of the single configuration is performed (FIG. 9).
Step S122). Here, it is assumed that the use of the “cluster configuration” has been selected. Information that the use of the “cluster configuration” has been selected is sent to server computer 100. Then, a plurality of server computers are clustered and displayed as shown in FIG. 23 (step S12).
3).

Next, after the user clicks the client terminal as shown in FIG.
When the button is selected, a list for selecting the client scale (the number of clients) is displayed on a menu, and the client scale is selected on the menu (step S124). Here, "Client 100
It is assumed that “table” has been selected. "Client 100
The information that “table” has been selected is stored in the server computer 10.
Sent to 0. Then, a plurality of client terminals are displayed as shown in FIG. 25 (step S125).

Next, processing for determining the model and performance of the client terminal is performed (step S126). That is, as shown in FIG. 25, the properties of the client are displayed in a menu by right-clicking the mouse, and the type of the client to be used (the type of operating system such as a workstation or a PC), the CPU speed (clock frequency), the memory size, and the disk capacity are used. Is selected by the user. The selected information is also sent to the server computer 100.

Thereafter, by selecting a WAN button, a security button, a directory button, and the like, selecting necessary components, and ending all processes, a system configuration corresponding to a condition specified by a screen operation by a user is established. It is determined (step S127). When the “price” button is selected by the user, the system introduction price corresponding to the current system configuration is calculated from the price and the number of each element stored in the know-how database 103 and displayed on the screen. (Step S128).
