BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a program execution system according to an embodiment that executes a reference source program that requires predetermined environment information such as a prerequisite program and environment setting information will be described.
[0014]
FIG. 1 is a diagram showing an outline of a program execution system of the present embodiment. As shown in FIG. 1, the reference source program 101 acquires information of the prerequisite program 103 in the file system or the network 105 by the environment relocator 102. The environment relocator 102 uses the database 104 to store the collected information.
[0015]
FIG. 16 is a diagram showing a configuration example of a conventional system. As shown in FIG. 16, in the conventional system, the reference source program 201 acquires the position of the prerequisite program 103 by the naming service 202.
[0016]
For example, if the program named TARGET PROG is the prerequisite program 103, the naming service 202 records the location information 203 of the prerequisite program, then starts the system, and when the prerequisite program 103 is needed inside the system. By inquiring the naming service 202, the position information 203 of the prerequisite program has been obtained from the naming service 202.
[0017]
In the present embodiment, the environment relocator 102 is prepared without performing the work of registering in the naming service 202 in advance, and when the reference source program 101 accesses the environment information, the environment relocator 102 always accesses the environment information. The referring program 101 makes a request to the environment relocator 102 instead of the naming service 202. The environment relocator 102 collects surrounding information, evaluates it, develops it into the most appropriate one, and passes it to the referring program 101. Here, what is required by the reference source program 101 is shown as the prerequisite program 103. However, the prerequisite is not limited to a program, and if the reference source program 101 requires one, a normal file is used. It may be.
[0018]
To collect environmental information, start by searching for nearby files. For example, assuming that the referring program 101 passes only the necessary file name to the environment relocator 102, the environment relocator 102 starts searching for the prerequisite program 103 by file name, mainly in a certain directory of the system. When a corresponding program is found as the prerequisite program 103, it is evaluated and the evaluation result is recorded together with its position.
[0019]
FIG. 2 is a diagram illustrating a schematic configuration of an information processing apparatus on which the environment relocator 102 of the present embodiment operates. As shown in FIG. 2, the information processing apparatus 110 according to the present embodiment includes a CPU 111, a memory 112, a magnetic disk device 113, an input device 114, an output device 115, a CD-ROM device 116, a communication device 117, have.
[0020]
The CPU 111 is a device that controls the operation of the entire information processing device 110. The memory 112 is a storage device that loads various processing programs and data for controlling the operation of the entire information processing apparatus 110.
[0021]
The magnetic disk device 113 is a storage device for storing the various processing programs and data. The input device 114 is a device that performs various inputs for setting information necessary for searching, evaluating, and determining environmental information such as the prerequisite program 103 and data files.
[0022]
The output device 115 is a device that performs various outputs in accordance with search, evaluation, and determination of environmental information such as the prerequisite program 103 and data files. The CD-ROM device 116 is a device for reading the contents of a CD-ROM in which the various processing programs are recorded. The communication device 117 is a device that communicates with another information processing device via a network such as the Internet or an intranet.
[0023]
In addition, the information processing apparatus 110 includes an environment information search processing unit 120, an environment information evaluation processing unit 121, and an environment information determination processing unit 122.
[0024]
The environment information search processing unit 120 stores the environment information such as the prerequisite program 103 and the data file requested by the reference source program 101 into a file system in the information processing apparatus in which the reference source program 101 is stored or a file system in the information processing apparatus. This is a processing unit that searches from the file system or the network 105, which is the file system of another information processing device connected via the network.
[0025]
The environment information evaluation processing unit 121 uses the searched environment information as a location where the environment information is stored, a version of the environment information, the number of users using the environment information, or the environment information. A processing unit that evaluates using metadata and stores the result in the database 104. The environment information determination processing unit 122 is a processing unit that extracts environment information that satisfies a predetermined condition from the environment information stored in the database 104 and passes it to the reference source program 101.
[0026]
A program for causing the information processing device 110 to function as the environment information search processing unit 120, the environment information evaluation processing unit 121, and the environment information determination processing unit 122 is recorded on a recording medium such as a CD-ROM and stored on a magnetic disk or the like. After that, it is loaded into the memory and executed. The recording medium for recording the program may be a recording medium other than the CD-ROM. Further, the program may be installed from the recording medium to the information processing apparatus and used, or the recording medium may be accessed through a network to use the program.
[0027]
FIG. 3 is a flowchart showing a processing procedure of a process in which the environment relocator 102 of the present embodiment collects and evaluates surrounding information. When the prerequisite program 103 is requested from the reference source program 101, the environment relocator 102 starts processing in step 301.
[0028]
In step 302, the environment information search processing unit 120 of the environment relocator 102 converts the environment information such as the prerequisite program 103 and the data file requested from the reference source program 101 into the information processing device 110 in which the reference source program 101 is stored. A search is performed from the file system or the network 105, which is the file system or the file system of another information processing apparatus connected to the information processing apparatus 110 via the network.
[0029]
In step 303, the environment information evaluation processing unit 121 of the environment relocator 102 converts the searched environment information into the location where the environment information is stored, the version of the environment information, the number of users using the environment information, Alternatively, a process of evaluating with metadata used in the environment information and storing the result in the database 104 is performed.
[0030]
In step 304, the environment information determination processing unit 122 of the environment relocator 102 extracts environment information that satisfies a predetermined condition such as the highest evaluation value from the environment information stored in the database 104 and sends the environment information to the reference source program 101. The process is passed, and the process is terminated in step 305 and control is returned to the reference source program 101.
[0031]
Next, the process of searching for environment information performed in step 302 will be described in detail with reference to FIGS.
[0032]
FIG. 4 is a flowchart illustrating a processing procedure of a process of searching the file system according to the present embodiment. When the process is started in step 401, in step 402, the environment information search processing unit 120 of the environment relocator 102 first extracts one unevaluated file from the current directory where the reference source program 101 is located, and then in step 403 Then, the environmental information evaluation processing unit 121 calculates an evaluation value of the file. If the file is the target, the result of the evaluation is recorded in the database 104 in step 404.
[0033]
Thereafter, in step 405, the environment information search processing unit 120 determines whether there is a file that has not been evaluated yet in the current directory, and if there is, extracts one unevaluated file and returns to step 402. If not, it is determined in step 406 whether there is a folder that has not been evaluated in the current directory. If there is a folder that has not been evaluated, it is set in step 407 as the current directory. If there is no folder that has not been evaluated, it is determined in step 408 whether the directory is the root directory. If the directory is not the root directory, the process goes back to the next higher folder in step 409. If it is the root directory, the process proceeds to step 410, and the file search process ends.
[0034]
FIG. 5 illustrates the processing in the above flowchart on a file system.
[0035]
FIG. 5 is a diagram illustrating an outline of a search process on the file system according to the present embodiment. Assuming that the reference source program 101 is Prog1 (501) as shown in FIG. 5, first, a file is searched for in the folder bin (503) where the reference source program 101 is located, and then a further upper folder Product1 (504) is searched. look for. This is repeated to search for the prerequisite program TARGET PROG (502).
[0036]
In the program execution system according to the present embodiment, when the file is not found on the current machine, the search range is further expanded to the surrounding machines by the network.
[0037]
FIG. 6 is a flowchart showing a processing procedure when searching through the network after searching for a program on the file system of the present embodiment. When the search of the file system having the reference source program 101 is completed, a search from the network is started in step 601. In step 602, the environment information search processing unit 120 of the environment relocator 102 firstly searches the current domain for one machine. In step 603, a search is made in the file system of the machine that has been taken out. The processing here is similar to the search of the file system in FIG.
[0038]
After the search in the machine is performed, it is determined in step 604 whether there is an unsearched machine in the domain. If there is still an unsearched machine, the process of extracting one machine from the current domain in step 602 Return to
[0039]
If there is no unsearched machine, it is determined in step 605 whether there is an unevaluated subdomain. If there is an unevaluated subdomain, it is set in step 606 as the current domain. Return to step 602.
[0040]
If there is no un-evaluated sub-domain, it is determined in step 607 whether there is a parent domain. If there is a parent domain, the current domain is traced back to the parent domain in step 608. If there is no parent domain above, the search via the network is terminated in step 609.
[0041]
FIG. 7 is a diagram illustrating a state of the search viewed from the domain arrangement according to the present embodiment. As shown in FIG. 7, when there is a referrer program 101 in machine1.soft.hitachi.co.jp (701), the next machine, machine2.soft.hitachi.co.jp (702), is first searched. Once all the machines in the soft.hitachi.co.jp domain (703) have been searched, the machine machine1.bisd.hitachi.co. In the next domain, bisd.hitachi.co.jp (704). jp (705) and machine2.bisd.hitachi.co.jp (706) are searched.
[0042]
FIG. 8 is a diagram illustrating a combination of the search of the file system and the search via the network according to the present embodiment. In response to a request from the referencing program (801) in FIG. 8, the environment relocator 102 first searches the file system (803) in which the referencing program (801) is stored, and then searches the own domain via the network. It finds the prerequisite program Target Prog (802) in the adjacent machine machine2.soft.hitachi.co.jp (805) in soft.hitachi.co.jp (804).
[0043]
The environment relocator 102 of the present embodiment collects information by performing a search as described above. Next, evaluation by the environment information evaluation processing unit 121 will be described. The environment information evaluation processing unit 121 evaluates the position, the version, the number of users, and the number of support items based on metadata (Metadata). The method of calculating the evaluation value for each is described below.
[0044]
FIG. 9 is a diagram illustrating an outline of the evaluation based on the file position according to the present embodiment. As shown in FIG. 9, in the evaluation of the position in the present embodiment, by increasing the evaluation as the position is closer, the one that is installed at the same time or that is closer to the network is given priority.
[0045]
If there is a Prog2 (902) under the hitachi folder that can be used as the prerequisite program 103 and a Prog2 (903) under the Adachi folder, the environment information evaluation processing unit 121 exists under the hitachi folder and refers to the source program (901). Prog2 (902) close to is regarded as a good evaluation. By giving priority to a program that is close to the reference source program, it is advantageous in terms of speed such that the prerequisite program is not passed through a network. The value used as the actual evaluation value indicates the position of the prerequisite program from the reference source program by a relative path including the network, and the number obtained by subtracting the number of path delimiters between them from a sufficiently large number is used as the evaluation value.
[0046]
In the evaluation of the version according to the present embodiment, the prerequisite program is set so that the version can be acquired, and the evaluation of a newer version is higher.
[0047]
FIG. 10 is a diagram showing an outline of the evaluation based on the file version of the present embodiment. As shown in FIG. 10, when the environment information search processing unit 120 finds Target Prog Ver1.0 (1002) and a new version of Target Prog Ver1.5 (1003), the environment information evaluation processing unit 121 Give new Target Prog Ver1.5 (1003) good evaluation.
[0048]
The newer the version, the less bugs it has and the new features are supported. As the actual evaluation value, normally, the larger the version number is, the newer the version is. Therefore, the version number itself is used. By performing the evaluation based on the version, the new system is preferentially used, so that when a failure occurs in the program, it is easy to take measures against an accident for correcting the failure.
[0049]
In this embodiment, a counter for counting the number of users when a prerequisite program is used in the system is provided in the environment relocator 102 in order to evaluate the number of users. With this counter function, the environmental information evaluation processing unit 121 performs a process of giving a better evaluation to a prerequisite program used by more users. This highly evaluated prerequisite program is used by many people and can be used with confidence. For this reason, the environment relocator 102 records the number of users so far on a database for each pass of the prerequisite program, and uses this number of users as an actual evaluation value.
[0050]
FIG. 11 is a diagram illustrating an example of the data structure of a database that records the number of users according to the present embodiment. The database in FIG. 11 includes a path (1101) indicating the location of the prerequisite program and the number of users (1102).
[0051]
The evaluation of the support items by the metadata of the present embodiment is performed by embedding a function of outputting metadata indicating what support items are present in the prerequisite program and using the information for evaluation.
[0052]
FIG. 12 is a diagram illustrating an example of metadata according to the present embodiment. As shown in FIG. 12, the environment information evaluation processing unit 121 has two support items, / opt / Adachi / Product1 / Prog1 (, from the prerequisite program / opt / hitachi / Product1 / Prog1 (1201) having only one support item. 1202) is a better evaluation. The evaluation based on the metadata should be a good evaluation depending on the number of support items. The number of support items is used as the actual evaluation value.
[0053]
As described above, the environmental information evaluation processing unit 121 performs the evaluation based on the four items, the evaluation of the position, the evaluation of the version, the evaluation of the number of users, and the number of support items by the metadata, and stores the evaluation result in the database 104. .
[0054]
FIG. 13 is a diagram illustrating an example of the data structure of the database 104 that records the evaluation result according to the present embodiment. The database 104 includes a path (1301) indicating the location of the prerequisite program 103 and an evaluation value (1302).
[0055]
When comprehensively evaluating these evaluations, it is assumed that the parameters differ depending on the user, such as when the closer one is better, the newer one is better, or the one used by many users is better. Conceivable. Therefore, in this embodiment, the user sets the priority of the evaluation value as a priority coefficient of each evaluation value. The environment information evaluation processing unit 121 multiplies this priority coefficient by each evaluation value, and sets the sum as a total evaluation value of the corresponding prerequisite program. This evaluation formula is shown in the following Expression 1.
[0056]
(Equation 1)
Overall evaluation value = (position evaluation value) x (position priority coefficient) + (version evaluation value) x (version priority coefficient) + (user number evaluation value) x (user number priority coefficient) + (Metadata evaluation value) x (Metadata priority factor)
[0057]
On the other hand, when searching for a prerequisite program, the search range may be too wide to cause a problem. Therefore, measures to be taken when the search takes a long time will be described. When a long time is required for the search, the search can be limited by limiting the search range or the search time. Therefore, the search is interrupted when a certain number is found in the search, or the user can set parameters such as to interrupt the search after a certain period of time has passed. For example, when a user finds several relevant prerequisite programs and makes it possible for the user to make settings to use them, the problem that the search takes too much time can be solved.
[0058]
As another application, the environment relocator 102 can handle a function compatible with the naming service. In the case of a distributed object environment, a naming service is often used. By registering in advance and referring to the naming service by the reference source program, it is possible to obtain information necessary for execution, such as a reference to the server. If the environment relocator 102 can respond as a naming service (Naming Service), there is no need to register in advance, and compatibility with conventional systems is convenient.
[0059]
FIG. 14 is a diagram illustrating an example of load distribution by the environment relocator 102 of the present embodiment. As shown in FIG. 14, when there are a plurality of reference sources such as a program 1 (1401), a program 2 (1402), and a program 3 (1403), an environment relocator is provided for each of the reference programs. By changing the answer of 102, load distribution can be performed.
[0060]
That is, when the prerequisite programs 103 having the same name are requested from a plurality of programs 1401 to 1403, the prerequisite programs 103 satisfying a predetermined condition such as the highest evaluation value among the environment information stored in the database 104. After extracting the information and passing the information to the program 1401, the information of the prerequisite program 103 that satisfies a predetermined condition is extracted from the environment information excluding the information already passed to the program 1401 and passed to the next program 1402. The information of the prerequisite program 103 on a different information processing device is passed to each of the programs 1401 to 1403.
[0061]
FIG. 15 is a diagram illustrating an example of grouping according to phases such as the development environment of the reference source program 101 according to the present embodiment. As shown in FIG. 15, as still another application, when the status of the referencing program is different, such as a program debug (1501), a program development version (1502), and a completed program version (1503), the environment relocator 102 transmits By passing the status, the prerequisite program returned by the environment relocator 102 can be changed between the reference source program under development and the reference version of the completed version. This function makes it possible to perform grouping according to phases such as a development environment.
[0062]
As described above, in the present embodiment, the environment information requested from the reference source program is searched and passed to the reference source program, so that the user does not need to set the naming service and environment variables in advance, and the prerequisite program is Even if the folder is moved to another folder or another server for some reason, the user can start the referencing program without having to manually update the setting information such as environment variables and setting files. Therefore, mistakes in writing the setting file and the like do not occur. Since the program can be operated with the latest environment information, the program can always be operated in the best environment.
[0063]
In addition, since a new system is used by evaluating by version, if a failure occurs, it is possible to take measures by installing the modified version near the requesting program, making it easier to take measures against accidents etc. . Also, if the accident countermeasure fails, the installed state can be returned to the previous state by immediately erasing it, so that the original state can be easily restored. In addition, since all are accessed via the environment relocator, dynamic replacement is also possible.
[0064]
As described above, according to the program execution system of the present embodiment, the environment information requested from the reference source program is searched and evaluated, and the environment information satisfying a predetermined condition is passed to the reference source program. It is possible to execute the execution module of the reference source program without setting the environment information by the user.
[0065]
【The invention's effect】
According to the present invention, the environment information requested from the reference source program is searched for and evaluated, and the environment information that satisfies a predetermined condition is passed to the reference source program, so that the user does not set the environment information before activation, It is possible to execute the execution module of the reference source program.
