Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a migration inspection program creation device, a migration inspection program creation method, and a migration inspection program creation program, and more particularly to a migration inspection program creation device that can efficiently perform a work of replacing a computer device that operates a program with a new one. Etc.

  In organizations such as corporations, government offices, and schools, a large number of computer devices and a computer network constructed by connecting them to each other function as the core of each business. In these computer apparatuses, a large number of computer programs that handle information indispensable for performing each business are operating. It is necessary to replace the computer device that runs each program with a new one for reasons such as the lapse of the useful life as hardware, the storage device capacity shortage, and the network configuration change accompanying an increase in communication capacity. Of course there are cases.

  At that time, there is almost no normal operation by simply transferring the execution file of the program from the old device to the new device. In many cases, in order for the program to operate correctly on a new device, it is necessary to redo the preparation of library files and log files, the directory configuration, and the setting of access rights. These settings are often different for each device or version even for computer devices operating on the same OS (operating system).

  As technical literature related to this, there are the following. Among them, Patent Document 1 describes a technique of easily tracing a system call that calls an OS function while a computer program is being executed by grouping a plurality of system calls.

  Patent Document 2 describes a technique of categorizing trace information recorded during operation of a computer program and hiding specific information to display only necessary information. Patent Document 3 describes an automatic test system for a computer program that generates a script and test data from a test program and performs a test. Patent Document 4 describes a simulated application test apparatus that requires no new test program creation even when the computer hardware is changed.

  When replacing the computer device that runs each program with a new one, especially when the device is executing a wide variety of programs such as an application server, check and maintain the operating environment for each program. Just doing it can be a huge amount of work. Most of the maintenance work is maintenance of paths of other program files that the program executes during operation, and paths and access rights of other files that are accessed during operation.

  The execution file of the program may be a script file in which sentences in the program language are described, or may be a binary file described only in binary numbers without assuming that humans read and write.

  If the executable file is a script, it may be possible to automate the confirmation and maintenance of the operating environment by performing a static analysis of the syntax line by line, but there may be cases where details of the operating environment cannot be confirmed. If the executable file is binary, such static analysis itself is extremely difficult, and in addition to the operating environment that the program requires during execution, intermediate files that are required during processing, etc. There is a problem that there are many cases where there is not enough description in manuals and specifications.

  In particular, when the executable file is binary, the program is executed on the migration destination device, and errors that occur during the execution of the program are resolved one by one while referring to the error log. There is no effective way other than adapting to a new device. Since this takes a lot of man-hours and time, it is particularly difficult to replace a device such as an application server that executes a large number of programs with a new one.

  The configuration that can solve the above problem is not described in the above-mentioned Patent Documents 1 to 4. None of these documents is intended to efficiently check and maintain the operating environment as described above, and does not describe a configuration that can make them efficient.

(First embodiment)
The configuration of the first embodiment of the present invention will be described below with reference to FIGS.
First, the basic content of the present embodiment will be described, and then more specific content will be described.
The migration inspection program creation device 10 according to the present embodiment records, as trace information, information issued to the OS of the migration source computer while the target program 25 operating on the migration source computer (migration source application server 20) is operating. The migration inspection program creation device creates a migration inspection program 120 for determining whether or not the target program is operable on a computer device (migration destination application server 30) other than the migration source computer from the trace file 24. The migration inspection program creation device 10 includes a trace file shaping function 102a for extracting trace information about execution and access of a file from a trace file, and execution and access of a file similar to the content of the extracted trace information. And a migration inspection program generation function 102b for creating a migration inspection program 120 for determining whether or not it is possible even in the computer apparatus.

  Here, the trace file shaping function 102a converts the trace information into environment information that does not depend on the execution environment, and stores it in the operating environment information storage unit 112 provided in advance.

  Further, the trace information related to the file execution includes information on the file path of the execution file, and the migration inspection program generation function 102b determines whether or not the execution file path is properly set in the migration inspection program. Include processing to be performed. Further, the trace information regarding the file access includes information on the path and access right of the access target file, and the migration inspection program generation function 102b correctly sets the path and access right of the access target file in the migration inspection program. A process for determining whether or not it has been performed is included.

With the above configuration, the migration inspection program creation device 10 of the present embodiment can efficiently perform a work of replacing the computer device that operates the target program 25 with a new one.
Hereinafter, this will be described in more detail.

  FIG. 1 is an explanatory diagram showing the configuration of the migration inspection program creation device 10 according to the first embodiment of the present invention. The migration inspection program creation device 10 has a configuration as a general computer device. That is, a main processing control means (CPU: Micro Processing Unit) 11 that is a main body for executing a computer program, a storage means 12 that stores data, and a communication means that is connected to a network 40 and performs data communication with other computers. 13 and an input / output unit 14 that receives an operation from the user and displays a processing result of the main arithmetic control unit 11 to the user.

  The migration inspection program creation device 10 performs data communication with the migration source application server 20 that is one or more computer devices and the migration destination application server 30 that is one or more computer devices via a network 40.

  In the main calculation control means 21 a provided in the migration source application server 20, a target program execution unit 22 that executes a computer program to be migrated (hereinafter referred to as a target program 25), and a trace file 24 by tracing the execution status of this program. The tracing unit 23 to be created is configured to execute each function as a computer program.

  At the same time, the migration source application server 20 also includes a storage unit 21 b that stores the trace file 24 and the target program 25, and a communication unit 21 c that performs data communication with other computer apparatuses via the network 40. Then, the trace unit 23 transmits the trace file 24 to the migration inspection program creation device 10 via the network 40. In the migration source application server 20, an environment in which the target program 25 can operate normally is prepared.

  The migration destination application server 30 is a computer device that can execute the migration inspection program 120 generated by the migration inspection program creation device 10, and is a computer device that intends to finally execute the target program 25. The trace file 24, the target program 25, and the migration inspection program 120 may be exchanged via a storage medium such as an optical disk or a flash memory, for example, without being exchanged via the network 40. .

  The main operation control means 11 of the migration inspection program creation device 10 includes a trace file collection unit 101 that receives the trace file 24 from the migration source application server 20, and a migration inspection that generates a migration inspection program from the received and collected trace file 24. The program generation unit 102 is configured to be executed as a computer program.

  The migration inspection program generation unit 102 is further divided into a trace file shaping function 102a for extracting necessary information from the received and collected trace file 24 and a migration inspection program generation function 102b for generating the migration inspection program 120 therefrom.

  The storage unit 12 of the migration inspection program creation device 10 stores the trace information storage unit 111 that stores the trace file 24 collected by the trace file collection unit 101 and the information extracted from the trace file 24 by the trace file shaping function 102a. An operating environment information storage unit 112 to be stored and an inspection function information storage unit 113 in which information used for generation of the migration inspection program 120 by the migration inspection program generation function 102b is stored in advance as storage areas.

  In the migration source application server 20, the trace unit 23 is a function of the OS while the target program 25 executed by the target program execution unit 22 is being executed, such as trace in Linux, tusc in HP-UX, and truss in Solaris. The system call issued for calling is acquired, and information such as the name, argument, and return value of the system call is output to the trace file 24 on the storage means 21b.

  The trace unit 23 transmits the trace file 24 that has been output to the migration inspection program creation device 10 via the network 40 (or a storage medium). In the migration inspection program creation device 10, the trace file collection unit 101 receives this and stores it in the trace information storage unit 111 using the application name as a key.

  FIG. 2 is a flowchart showing the operation of the trace file shaping function 102a shown in FIG. The trace file shaping function 102a reads trace information related to a specific application from the trace information storage unit 111 (step S201), and extracts trace information related to file execution and trace information related to file access from the trace information storage unit 111 (step S202). .

  FIG. 3 is an explanatory diagram illustrating an example of trace information extracted from the trace information storage unit 111 by the trace file shaping function 102a in steps S201 to S202 in FIG. Taking Unix (registered trademark) as an example, the exec system call corresponds to “trace information related to file execution”, the open system call corresponds to “trace information related to file access”, and is the target to be extracted in step S202. .

  Returning to FIG. 2, the trace file shaping function 102a further extracts the trace information extracted in step S202 from the trace information that has been successfully executed, the trace name (system call name) and necessary arguments from the trace. Is extracted (step S203). In the case of the exec system call, the trace name is “exec” and the necessary argument is “executable file path”. In the case of an open system call, the trace name is “open”, and necessary arguments are “file path of the target file to be opened” and “access right of the file”.

  The trace file shaping function 102a converts the argument extracted in step S203 into environment information independent of the trace information of the execution server (step S204). The environment information here includes an environment name 112b and accompanying information 112c. The environment name 112b is a virtual name indicating how the application behaves, and the accompanying information 112c is information accompanying the environment. By this conversion, it is possible to unify the format of the trace information that differs depending on the type of the trace unit 23.

  In the case of the exec system call shown in FIG. 3, the data such as (exec, file path of the execution file) has the environment name 112b in which “exec” is “execution of file” and “file path of the execution file” is accompanying information. 112c. In the case of an open system call, data such as (open, file path, execution mode) has an environment name 112b in which “open” is “file access”, and “file path” and “execution mode” are accompanying information 112c.

  The trace file shaping function 102a excludes known trace information not particularly related to the execution environment from the trace information extracted in step S202 and subjected to the processing in steps S203 to 204 (step S205). The “known trace information not particularly related to the execution environment” to be excluded here is, for example, access to a temporary directory or access to a general file or directory that is not unique to the target program 25. .

  The trace file shaping function 102a stores the environment name 112b and the accompanying information 112c of the trace information that has been processed up to step S205 in the operating environment information storage unit 112 using the application name 112a of the target program 25 as a key (step S206). ). Finally, the trace file shaping function 102a determines whether or not unreferenced data remains in the trace information storage unit 111 (step S207), and if it remains, returns to step S201 to perform a step on the unreferenced data. The processes of S202 to 206 are repeated. If not, the process ends.

  FIG. 4 is an explanatory diagram showing an example of environment information data stored in the operating environment information storage unit 112 by the trace file shaping function 102a by the process shown in FIG. As described above, the operating environment information storage unit 112 stores the environment name 112b and accompanying information 112c of the target program 25 corresponding to the application name 112a of the target program 25.

  In the example of the environment information data stored in the operating environment information storage unit 112 shown in FIG. 4, for the application name 112a “application A”, the environment name 112b = “file execution” and the accompanying information 112c = “file path X”. ”, Environment name 112b =“ file access ”, and accompanying information 112c =“ file path Y ”and“ access right “read” ”are stored.

  Similarly, in the operating environment information storage unit 112, for the application name 112a “application B”, the environment name 112b = “file access” and the accompanying information 112c = “file path Z” and “access right“ write / read ””. Is also stored.

  5 to 6 (divided into two for convenience of paper) are flowcharts showing the operation of the migration inspection program generation function 102b shown in FIG. The migration inspection program 120 generated by the migration inspection program generation function 102 b is a program that can be executed by the migration destination application server 30. In the present embodiment, the migration inspection program 120 is described by a shell script.

  Among the steps described in FIG. 5 to FIG. 6, there is one in which the migration inspection program generation function 102 b creates a shell script code, and these created codes are added to one text file, which is the final result. Therefore, it is output as the migration inspection program 120. Specifically, the operations in steps S301, 302, 306, 308, and 310 are the ones in which the migration inspection program generation function 102b outputs a code.

  The migration inspection program generation function 102b first creates a header of the migration inspection program 120 (step S301), and subsequently creates a code that initializes the return value storage variable to “success” (step S302). Since a shell script is used in this embodiment, the header created in step S301 is, for example, “#! / Bin / sh”. The return value storage variable created in step S302 is a Boolean variable indicating success as 0 and failure as 1, for example, “ret = 0”.

  When the initial value generation is completed, the migration inspection program generation function 102b subsequently reads information about the application name 112a of the specific target program 25 from the operation environment information storage unit 112 (step S303), and the environment name 112b and The accompanying information 112c is read (step S304).

  Subsequently, the migration inspection program generation function 102b reads the inspection function corresponding to the environment name 112b from the inspection function information storage unit 113 as a key (step S305). FIG. 7 is an explanatory diagram illustrating an example of contents stored in the inspection function information storage unit 113 illustrated in FIG. 1. In the inspection function information storage unit 113, an inspection function 113a corresponding to the environment name 112b is stored in advance. In the present embodiment, the check function 113a is a shell script function.

  The checking function 113a is a function that checks the operating environment using the application name 112a and the accompanying information 112c as arguments and determines whether or not the target program 25 indicated by the application name 112a can operate. If it can operate, “success” is output, otherwise “failure” and its “reason for failure” are output.

  In this embodiment, since the check function 113a is a shell script function, the File_exec_check {} function, which is a “file execution” check function corresponding to the exec system call, and the “file access” function corresponding to the open system call. A File_access_check {} function that is a check function is stored.

  Returning to FIG. 5, the migration check program generation function 102b applies the application name 112a and the accompanying information 112c as arguments to the check function 113a read in step S305, and creates a code that is a fragment of the transfer check program 120. (Step S306). In this code, when the return value of the check function is failure, the return value storage variable initialized in step S302 is set to a numerical value indicating failure, such as “ret = 1”.

  The migration inspection program generation function 102b determines whether or not the unprocessed environment name 112b remains in the information about the application name 112a read in step S303 (step S307). The processes in steps S304 to S306 are repeated for the name 112b. If not, the process proceeds to step S308.

  Subsequently, the migration inspection program generation function 102b determines whether the return value storage variable is 0 or 1, that is, whether the target program 25 can operate on the migration destination application server 30. A code for outputting the result is generated (step S308).

  Subsequently, it is determined whether or not the information about the application name 112a of the other target program 25 remains unprocessed in the operating environment information storage unit 112 (step S309). The processes in steps S303 to S308 are repeated for the reference data. If not, a footer for the migration inspection program 120 is created (step S310), and the process ends. In the shell script used in the present embodiment, a footer is not particularly necessary. However, if it is desired to generate an inspection program in another language, a footer may be necessary.

  FIG. 8 is an explanatory diagram showing an example of the migration inspection program 120 created through the operations of FIGS. 5 to 6 and the execution result 121 obtained by executing it on the migration destination application server 30. As described above, the operation environment information storage unit 112 shown in FIG. 4 stores the environment name 112b = “file execution”, the accompanying information 112c = “file path X”, and the environment name 112b for the application name 112a “application A”. = Environmental information data of “file access” and accompanying information 112c = “file path Y” and “access right“ read only ”” are stored.

  Similarly, in the operating environment information storage unit 112, for the application name 112a “application B”, the environment name 112b = “file access” and the accompanying information 112c = “file path Z” and “access right“ write / read ”. Is also stored.

  Therefore, the migration inspection program generation function 102b, as the migration inspection program 120, for the application name 112a “application A”, “whether or not an executable file with file path X exists” and “access right to file path Y” are read only. A process for confirming whether or not “a file exists” and a process for confirming whether or not a file with the access right “write / read” exists in the file path Z for the application name 112a “application B”. Describe and output.

  The execution result 121 is a result output by executing the migration inspection program 120 on the migration destination application server 30. In the example shown in FIG. 8, there is an executable file corresponding to the processing of “whether or not an executable file of file path X exists”, but “a file with an access right“ read only ”in file path Y”. As for the process of “whether or not exists”, the access right of the corresponding file is not “read only”. Therefore, the migration inspection program 120 outputs “NG”, that is, “Application A cannot operate on the migration destination application server 30”. At the same time, the migration inspection program 120 outputs a failure reason, that is, “no read access authority”.

  Similarly, regarding the processing of “whether or not a file with access right“ write / read ”exists in the file path Z”, the access right of the corresponding file is correctly set to “write / read”. The migration inspection program 120 outputs “OK”, that is, “Application B can operate on the migration destination application server 30”.

  As can be seen from the example described above, the operating environments of the plurality of target programs 25 can be tested together by a single migration inspection program 120. Conventionally, the user (computer system administrator) had to resolve the errors that occurred when the target program 25 was executed by the migration destination application server 30 one by one. , The points that may cause errors in the operation of the target program 25 can be solved together, and the migration of the target program 25 to the migration destination application server 30 can be performed efficiently.

(Overall operation of the first embodiment)
Next, the overall operation of the above embodiment will be described. In the migration inspection program creation method according to the present embodiment, information issued to the OS of the migration source computer while the target program 25 operating on the migration source computer (migration source application server 20) is operating is recorded as trace information. In the migration inspection program creating apparatus 10 for creating a migration inspection program for determining whether or not the target program is operable on a computer device (migration destination application server 30) other than the migration source computer from the trace file 24, the trace file Trace information about the execution and access of the file is extracted by the trace file shaping function 102a (FIG. 2, steps S202 to S206), and the execution and access of the same file as the contents of the extracted trace information is another computer apparatus. smell Migration test program generation function 102b migration test program to determine whether it is possible to create (Figure 5-step S303~306).

Here, each of the above-described operation steps may be programmed so as to be executable by a computer, and these may be executed by the migration inspection program creating apparatus 10 which is a computer that directly executes the respective steps. The program may be recorded on a non-temporary recording medium, such as a DVD, a CD, or a flash memory. In this case, the program is read from the recording medium by a computer and executed.
By this operation, this embodiment has the following effects.

  According to the present embodiment, library files and log files used when the target program 25 operates on the migration source application server 20, directory configuration, access right settings, and the like are collectively processed on the migration destination application server 30. As a result, the operating environment of the migration destination application server 30 can be easily maintained.

  In particular, even when there are a large number of target programs 25 that need to be migrated from the migration source application server 20 to the migration destination application server 30, the migration inspection program 120 need only be executed in a lump, and therefore the man-hours required for migration of computer devices And time can be greatly reduced.

(Extended embodiment)
The first embodiment described above can be extended in various ways without changing the gist of the first embodiment. For example, the migration inspection program creation device 10 and the migration source application server 20 may be the same computer device, and the migration inspection program creation device 10 and the migration destination application server 30 may be the same computer device.

  In particular, the migration inspection program creation device 10 and the migration source application server 20 are the same computer device, the migration source application server 20 creates the migration inspection program 120 from the trace file 24, and the migration destination application server 30 has a plurality of migration inspection programs 120. It is also possible to configure the migration inspection program 120 created by the migration source application server 20 to be combined and executed together.

  The trace file 24 often has a large capacity. In particular, when there are a plurality of migration source application servers 20 having a plurality of target programs 25, the amount of data that must be transmitted to the migration destination application server 30 is enormous. Therefore, by creating the migration inspection program 120 on each migration source application server 20 side, it is possible to reduce the volume of data transmitted to the migration destination application server 30.

  The present invention has been described with reference to the specific embodiments shown in the drawings. However, the present invention is not limited to the embodiments shown in the drawings, and any known hitherto provided that the effects of the present invention are achieved. Even if it is a structure, it is employable.
