Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a client terminal device and a server device both connected by a network.
The present invention relates to a technique effective when applied to a network computer system that loads a necessary program from the server device to the client terminal device via a network and executes the program.

[0002]

2. Description of the Related Art "Nikkei Electronics 1997.4.
21 (No. 687) ", in a conventional network computer system, a client terminal device connects to a server device at the time of startup and loads and executes a basic control program from the server device. When executing an application program on the client terminal device, the user issues a load request to the server device by designating the name and version of the application program to be executed. The server device has a function of searching for an application program requested by the client terminal device from a group of application programs stored in the external storage device and transferring the application program to the client terminal device.

[0003]

In the above-described conventional network computer system, various versions having individually operating conditions are mixed in an application program stored in a server device, and whether or not the application program can be executed is determined by a load. Since it depends on the consistency with the configuration information (hardware and the basic control program being executed) of the client terminal device which issued the request, the user must load the client terminal device beforehand in order to load the executable program. It is necessary to check the consistency between the machine configuration information and the operating conditions of the application program to be executed, and determine which program (version) is executable.

As a result of the above-described consistency determination, if there is no executable program in the configuration of the client terminal device in use, for example, if only the basic control program is inconsistent, the application program is executed. In order to solve the problem, the user himself devises an investigation and a solution to the factors that make the requested application infeasible, such as rebuilding the environment by reloading a basic control program that is compatible with the requested application. Maintenance had to be done manually.

If the user does not sufficiently grasp the information necessary for determining the above-mentioned consistency, it is determined whether or not the program which has issued the load request can be executed once. Unless otherwise clear, the user may have to repeat trial and error and waste time loading unexecutable programs. Further, when there is no executable program in the server device, all the programs are loaded and executed, and the user cannot recognize that there is no executable program in the server device until the program ends in failure.

[0006] Even when the loaded application program can be executed, if the loading and execution of the application program causes a shortage of memory and deterioration of performance of the client terminal device, it can be said that the operating environment is comfortable for the user. Absent. A comfortable operating environment, which is perceived differently by the user, may indicate good performance, an environment in which multiple applications can be executed simultaneously, or an environment in which the latest version of an application program can be executed. . In the conventional network computer system, the execution environment of the program is inevitably determined from the machine configuration information of the client terminal and the execution condition of the initially loaded program, and there is no guarantee that the program can be executed in an operation environment that is comfortable for the user. Was. In addition, there is no means for the user to set the execution environment of the program.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art, and a server device which receives a load request from a client terminal device selects an executable program before transferring the program, and In the case where there is an application requested by the user and there is an executable program, the user must load and execute the requested program at once without being aware of machine configuration information or operating conditions of the program. it can,

FIG. 13 shows an extraction result table 1300 prepared for writing the execution condition of only the program determined to be executable during the process of extracting the executable program shown in FIG. It is a figure showing an example of. For example, the value of the item “network address” located at the first row in FIG.
ID00010 ”, the value of item“ Basic control program ”is“ OS_A
1.0 ”, the value of the item“ free memory amount ”is“ 250 KB ”,
The user identifier “rits” using the client terminal device 110 in which the value of the item “CPU” has “180 MHz”
uko ”is the application program A
Is requested, the application execution condition pattern table 2 is obtained from the application execution condition pattern table 200 and the first-stage information of the machine configuration information management data 300 extracted from the network address.
At 00, the value of the item “application program A” having “pattern IDs” 1 and 2 is extracted as an executable program and written into the extraction result table 1300 along with information on other items.

In FIG. 13, reference numeral 1301 denotes an identification number (hereinafter referred to as “extraction I” for managing the extraction result table for each column.
D) and 201 to 205 indicate operating conditions of the application program copied from the application execution condition pattern table. 1302-1304 are
This is an item indicating whether each program indicated by the value of the item “application program” satisfies the priority set by the user for each element that determines the execution environment of the application. “True” means that the priority set by the user is satisfied, and “False” means that the priority is not satisfied. As shown in step 1207, all values are initialized to “False” when an executable program is extracted.

As shown at 1302 to 1304, the items of the priority check are the number of attributes set by the user in the application execution environment tuning data 400,
That is, three are prepared. The value of the item “priority check 1” indicates whether the attribute set with the highest priority satisfies the condition set by the user, and the value of the item “priority check 2” has the second highest priority. For the attribute, the value of the item "priority check 3" indicates whether the attribute with the lowest priority satisfies the condition set by the user. Therefore, the priority attributes indicated by “priority check 1” to “priority check 3” are different for each executing user.

FIG. 14 is a flowchart showing step 1106 of FIG.
9 is a flowchart illustrating a processing procedure of “execution priority check processing” 1400 executed when there are a plurality of executable programs. The execution priority inspection process 1400 is as follows: (1) The extraction result table 1300 of FIG. 13 is opened (step 1401).

(2) Using the user identifier as a key, a value of a corresponding application execution environment tuning parameter is extracted from the application execution environment tuning data 400 (step 1402).

(3) In step 1402, the values of the attributes of the extracted tuning parameters are compared, and priority 1, priority 2, and priority 3 are assigned in order from the attribute with the highest value (step 1403).

(4) An initial value 1 is set to a variable n representing the priority of the attribute under inspection (step 1404).

(5) It is checked whether the inspection has been completed for all “extraction IDs” included in the extraction result table (step 1405).

(6) In step 1405, for all “extraction IDs” included in the extraction result table,
If the inspection has not been completed, for the attribute of priority n,
A condition determination formula is selected and executed (step 1500, details of which will be described later in steps 1501 to 1505).

(7) In step 1405, for all “extraction IDs” included in the extraction result table,
If the inspection has been completed, the process ends.

(8) In step 1405, for all “extraction IDs” included in the extraction result table,
If the inspection has not been completed, as a result of the processing in step 1500, it is checked whether or not each item having the extraction ID under inspection satisfies the condition determination formula for the attribute of priority n (step 1407).

(9) In step 1407, as a result of performing the processing in step 1500, “extraction I
When each item having “D” satisfies the condition determination formula for the attribute of the priority n, “True” is written to the value of the item “priority check n” in the extraction result table 1300 (step 1408). FIG. 1 shows the extraction result table after the processing is completed.
7 will be described later.

(10) In step 1407, as a result of performing the processing in step 1500, “extraction I
If each item having "D" does not satisfy the condition determination formula for the attribute of the priority n, the process returns to step 1405.

(11) In step 1407, as a result of performing the processing in step 1500, “extraction I
When each item having “D” satisfies the condition determination formula for the attribute of the priority n, 1 is added to the variable n representing the priority of the attribute to be inspected after the processing of step 1408, and The attribute is changed to the attribute with the next highest priority (step 1409).

(12) In step 1407, as a result of performing the processing in step 1500, “extraction I
When each item having “D” satisfies the condition determination formula for the attribute of the priority n, after the processing of step 1409, n
Is determined to be equal to 3, and it is determined whether the inspection has been completed for all the attributes of the priority (step 1410).

(13) If the inspection has been completed for all the attributes in step 1410, the process returns to step 1405.

(14) If the inspection has not been completed for all attributes in step 1410,
Return to step 1500.

FIG. 15 is a flowchart showing step 1405 in FIG.
In the following, a description will be given of a processing procedure of a process 1500 for selecting and executing a condition determination expression for an attribute of priority n, which is executed when inspection is not completed, for all executable programs included in the extraction result table. It is a flowchart. The processing 1500 for selecting and executing a condition determination formula for the attribute of the priority n is as follows: (1) Check whether the attribute of the priority n under inspection is “performance” (step 1501).

(2) In step 1501, when the attribute of the priority n under inspection is “performance”, “judgment expression_
"Performance" (for details, see FIG. 16 described later) is selected and executed (step 1502).

(3) In step 1501, if the attribute of the priority n under inspection is not “performance”, it is checked whether the attribute of the priority n under inspection is “memory” (step 1503).

(4) In step 1503, the attribute of the priority n under inspection is “memory”.

In this case, “determination formula_memory” (detailed in FIG. 16) is selected and executed (step 1504).

(5) In step 1503, if the attribute of the priority n under inspection is not “memory”, the attribute of the priority n under inspection is “version”, so “judgment expression_version” (details) Selects and executes (FIG. 16) described later (step 1505).

FIG. 16 is a flowchart showing step 150 in FIG.
Specific calculation formulas of “judgment formula_performance”, “judgment formula_memory”, and “judgment formula_version” shown in 2, 1504, and 1505 are shown. Based on the above three determination expressions, it is determined whether or not the executable program extracted in step 1200 realizes an application execution environment desired by the user. 1601 is “judgment expression_
The calculation formula of "performance" is shown. Numerical values to be used are “value of required condition of item“ CPU ”of application execution condition pattern table” and “value of recommended condition”, “value of item“ performance ”of application execution environment tuning parameter set by user”, And “the value of“ CPU ”of the client terminal device 110 used by the user” extracted from the machine configuration information management data.

In FIG. 4 and FIG. 5, it is described that the lowest value (in the case of the lowest priority) of the tuning parameter is set to 0, and the highest value (in the case of the highest priority) is set to 1. In the “judgment expression_performance”, when the value of the tuning parameter of “performance” is 1, the value of the item “CPU” of the machine configuration information of the client terminal device 110 is changed to the item “CP” of the application execution condition pattern table.
If the value of the recommended condition of “U” is required and the value of the tuning parameter is 0, it is determined that the value of the required condition of the item “CPU” of the application execution condition pattern table is required to be satisfied. If the value of “CPU” in the information is equal to or more than “the value of the essential condition + (the difference between the value of the essential condition and the value of the recommended condition) × (the value set in the tuning data)”, the value of the tuning parameter set by the user It is determined that the condition is satisfied (1601).

In the “judgment formula_memory” 1602, similarly to the “judgment formula_performance”, when the value of the tuning parameter of “memory” is 1, the item “free memory” of the machine configuration information of the client terminal device 110 Is required to satisfy the recommended condition value of the item "necessary memory amount" of the application execution condition pattern table, and if the value of the tuning parameter is 0, the item "necessary memory amount" of the application execution condition pattern table It is assumed that the value of the required condition is required to be satisfied, and the value of the “free memory amount” of the extracted machine information is calculated as “the value of the required condition + (the difference between the value of the required condition and the value of the recommended condition) × (the tuning data If the value is equal to or more than "), it is determined that the value of the tuning parameter set by the user is satisfied (1602).

Reference numeral 1603 denotes the client terminal device 110
4 shows a calculation formula of “judgment formula_version” selected when the highest priority is set to the latest version of the application program to be executed. Unlike the above two determination formulas, the version has neither essential nor recommended conditions, so the data to be used is the priority value of “version” set in the tuning data,
The number of executable programs and the “extraction ID” to be inspected.

Using the total number of columns of the extraction result table 1300 generated after the processing 1200 for extracting all executable programs in FIG.
If the value of the tuning parameter of “1” is 1, the newest version of the program, ie, “extraction ID”, as long as it satisfies the values of the other attributes “memory size” and the required condition of “CPU” in the application execution condition pattern table Is required to select the program with the largest value of
In the case of (1), it is assumed that it is required to select a program of the oldest version, that is, a program having the smallest value 1 of “extraction ID”,
D ”is equal to or more than“ 10 × (value of “version” of extracted tuning data) ÷ (number of executable programs) ”and“ 10 × (value of “version” of extracted tuning data)} ( If the number is equal to or less than (number of executable programs) +1 ”, it is determined that the value of the tuning parameter of the“ version ”desired by the user is satisfied (1603).

FIG. 17 shows the extraction result table 13 after execution of the run-time priority check process 1400 shown in FIG.
00 is an example. In the example given in the description of FIG. 13,
After the extraction result table is created, the application execution environment tuning data 400 in FIG. 4 is searched using the user identifier “ritsuko” as a key, and the corresponding tuning parameter value existing in the first stage in FIG. 4 is referred to. Then, when a process of selecting an application program for realizing the operation environment desired by the user from the executable programs according to the determination formulas shown in FIGS. 15 and 16 is performed, in the above example, as shown in 1701 to 1703 , “Extraction ID” in the extraction result table 1300
Is "1", "True" is written in the items "priority check 1" to "priority check 3". In the above example,
“Ver1.0”, which is the value of the item “application program A” having “1” in the “extraction ID”, is an optimal program that is executable and realizes an operation environment desired by the user at the time of execution. Is shown.

“Ver1.1” which is the value of the item “application program A” having “2” in the “extraction ID”
Is executable and the version is newer, but the values of the items "priority check 1" to "priority check 3" all remain at the initial value "False". For a user who desires "performance" as the highest priority, it can be said that this is not the optimal program to be transferred.

However, as shown in FIG. 17, it is not always the case that all the values from the items “priority check 1” to “priority check 3” become “True”.
Also, “Ve” of the program A having “1” in the “extraction ID”
For example, there may be a case where there are a plurality of programs whose attributes are “True”, such as “r1.0”. Even if a judgment formula is selected and calculated according to the execution priority set by the user, the program to be transferred is not always determined uniquely. Therefore, step 18 in FIG.
The “transfer program final decision processing” described briefly at 00 is required. The details will be described below.

(9) In step 1806, if the value of the item “priority check 3” having the “extraction ID” under inspection is “True”, the item “application program” having the “extraction ID” under inspection Is determined as the transfer program (step 1807).

(10) In step 1806, if the value of the item “priority check 2” having the “extraction ID” under inspection is “False”, the flow returns to step 1801.

(11) In step 1801, when the inspection has been completed for all “extraction IDs”, the extraction IDs in which all the values of the item “priority check n” are “True” are included in the extraction result table. In order to indicate that no error occurs, "selection exception processing" is performed (step 1900, details of which will be described later in steps 1901 to 1907).

[0142]

The effects obtained by the representative ones of the inventions disclosed in the present application will be briefly described as follows.

(1) When an application program is requested to be loaded from the client terminal device, executable components are automatically extracted from the operating conditions of the application and the hardware configuration information of the client terminal device.
Furthermore, the program that is determined to be executable in the optimal execution environment for the user is transferred based on the runtime priority of each element that determines the execution environment of the application set by the user. Without having to be aware of the hardware configuration information of the client terminal device
An executable application program can be loaded and executed in a comfortable operating environment.

(2) If the load-requested application program cannot be executed on the client terminal device, it is checked whether there is a combination of the basic control program and the application that can be automatically executed on the client terminal. A screen for inquiring the user whether or not to prepare the application execution environment by changing the machine configuration of the client terminal device is displayed, and the basic control program and the application program are transferred and requested only when the user desires. In order to automatically maintain the execution environment of the application program on the client terminal device, the user can execute a program that cannot be loaded and executed on the client terminal device in use without devising a solution without himself. Just hope It is possible to obtain an execution environment for determined application. In addition, since the user's request is reflected, if the user does not want to change the environment, reloading of the basic control program can be refused, and the user can flexibly respond to the usage situation.

(3) In (2), if there is no executable program even after reloading the basic control program, the executable program can be executed on the client terminal being used in the server without transferring. Since an error message indicating that the program does not exist is displayed on the client terminal, the user cannot execute the requested program on the client terminal in use without issuing a load request without waiting for the end of the transfer of the program. And avoid wasting time loading unexecutable programs.

(4) Since the program server has means for allowing the user to set the priority of each element for determining the execution environment of the application, the user or the system administrator can determine the optimum operating environment according to the usage situation. The priority of each element that determines the execution environment of the application can be set to be constructed.
