Description

  The present invention relates to a script generation program and a batch execution system for dynamically generating a batch script, and in particular, a batch script can be dynamically generated for servers having different combinations of available batch systems and script languages. The present invention relates to a script generation program and a batch execution system that can easily cope with various batch systems and script languages.

  In recent years, an information processing method called grid computing has attracted attention. Grid computing is a system in which a plurality of computers are connected via a network to form a large-scale virtual computer, and load is distributed among the computers forming the virtual computer to effectively use resources.

  Here, consider a case where batch processing is executed in a grid computing environment. When batch processing is executed in a grid computing environment, the environment of each computer constituting the virtual computer becomes a problem.

  When a large amount of batch processing is executed by a computer, it is common to use a system called a batch system that performs batch queue management, but there are various types of batch systems. Defines a specific batch script format. There are also several types of script languages for describing batch scripts, each with a different syntax.

  There is no problem if the same batch system and scripting language can be used on all the computers that make up the virtual computer, but the actual grid computing environment is often a heterogeneous environment that uses existing computers. It may be difficult to standardize the system and script language.

  In order to make a virtual computer execute a batch script without sharing the script language with the batch system, a mechanism for dynamically generating the batch script according to the computer to which the execution of the batch script is assigned is provided in the virtual computer. Just do it.

  A technique for generating a batch script in accordance with the execution environment is disclosed in Patent Document 1, for example. If this technology is used, a batch script having a format corresponding to the target batch system can be generated by adding a start sentence and an end sentence corresponding to a specified keyword together with the batch script to the batch script.

  Exemplary embodiments of a script generation program and a batch execution system according to the present invention will be explained below in detail with reference to the accompanying drawings.

  First, the configuration of the batch execution system according to the present embodiment will be described. FIG. 1 is a block diagram illustrating a configuration of a batch execution system according to the present embodiment. As shown in the figure, the batch execution system 1000 is connected to operator terminals 101 to 107 that request job execution via a network or the like. Note that the number of operator terminals shown in the figure is an example, and it is not necessary to follow this number.

  The batch execution system 1000 includes a job input device 200 that functions as a front end, and servers 310 to 340 that are devices that actually execute jobs, and functions as a virtual computer that is connected via a network or the like. Note that the number of servers illustrated is an example, and it is not necessary to follow this number.

  The job reception unit 210 is a processing unit that receives job execution requests from the operator terminals 101 to 107. The job queue management unit 220 is a processing unit that stores the job received by the job reception unit 210 in a queue and manages the state. The server selection unit 230 is a processing unit that monitors the load status of the servers 310 to 340 and selects a server to be assigned to an unprocessed job stored in a queue.

  The script generation unit 240 and the server selection unit 230 are processing units that generate a batch script corresponding to the batch system and script language of the server selected. The script input unit 250 is a processing unit that inputs the batch script generated by the script generation unit 240 to the server selected by the server selection unit 230.

  The servers 310 to 340 are devices that execute batch scripts, and each have a different batch system and script language. For example, the server 310 uses the batch system A to execute a batch script written in sh (standard shell). Further, the server 20 executes a batch script described in Perl using the batch system B.

  Here, for convenience of explanation, one server is provided with one script language, but one server may be provided with a plurality of script languages. Further, although all the servers are illustrated as having different batch systems and script languages, there may be servers in which one or both of the batch systems and the script languages are the same.

  Next, the configuration of the script generation unit 240 that is a characteristic part of the batch execution system 1000 will be described. The substance of the script generation unit 240 is a script generation program 400, which is stored in the job input device 200 or a storage device of another computer, and is stored in the memory of the job input device 200 by the processor of the job input device 200. It is expanded and executed.

  The script generation program 400 receives as input the job definition data received by the job input device 200, the name of the batch system for which the batch script is generated, and the script language name, and executes the generated batch script and the batch script. Command file for output.

  FIG. 2 is a block diagram illustrating a configuration of the script generation program 400. As shown in the figure, the script generation program 400 includes a batch driver selection unit 410, a batch driver table 420, a batch driver 430, a language driver selection unit 440, a language driver table 450, a language driver 460, a script. A generation unit 470.

  The batch driver selection unit 410 is a processing unit that refers to the batch driver table 420 and selects a batch driver module corresponding to the batch system name received as input. The batch driver table 420 is a correspondence table between names of batch systems and batch driver modules for generating batch scripts corresponding to the batch systems.

  The batch driver 430 is a collection of batch driver modules for generating a batch script corresponding to a specific batch system, and each batch driver module has a common interface and can be operated in the same procedure. It has become.

  The language driver selection unit 440 is a processing unit that refers to the language driver table 450 and selects a language driver module corresponding to the script language name received as input. The language driver table 450 is a correspondence table between script language names and language driver modules for generating a batch script corresponding to the script language.

  The language driver 460 is a collection of language driver modules for generating a batch script corresponding to a specific script language, and each language driver module has a common interface and can be operated in the same procedure. It has become.

  The script generation unit 470 is a processing unit that generates a batch script by controlling the batch driver module selected by the batch driver selection unit 410 and the language driver module selected by the language driver selection unit 440 in combination.

  As described above, the script generation program 400 according to the present embodiment generates a batch script by combining the batch driver module prepared for each batch system and the language driver module prepared for each script language. In this way, by separating the modules that depend on the batch system and the modules that depend on the script language, even if the number of corresponding batch systems and script languages increases, it is possible to adapt by simply adding the corresponding module. Is possible.

  Before describing the details of the batch driver module and language driver module, the format of the batch script and job definition data will be described. FIG. 3 is a sample diagram illustrating a format of a batch script generated by the script generation program 400 according to the present embodiment.

  As shown in the figure, the batch script generated by the script generation program 400 includes a start instruction, batch-dependent preprocessing, language-dependent preprocessing, batch language-dependent preprocessing, body text, and batch language-dependent postprocessing. It consists of language-dependent post-processing. This format is compatible with all batch systems and scripting languages.

  The activation instruction is a part for designating a script language for executing the batch script. In the example of FIG. 3, “#! / Bin / sh” is set, and this description specifies that this batch script is executed by sh. The description of the start instruction depends on the script language to be generated.

  The batch-dependent preprocessing is a part in which preprocessing specific to the batch system is described in a parameter specification form. The batch system has a function of transferring a file necessary for processing, a function of sending an e-mail when an abnormality occurs, and the like, and parameters necessary for functions specific to the batch system are described here. In the example of FIG. 3, a comment starting with the character string “# $” corresponds to a parameter for a function specific to the batch system. Here, an input / output file name that needs to be transferred and an email address for notification of an abnormality It is specified. The description of batch-dependent preprocessing depends on the batch system to be generated.

  The language-dependent preprocessing is a part describing preprocessing specific to the script language. Depending on the script language, there may be routine processing that should be performed before other processing is executed, and such processing is described here. In addition, functions and variables necessary for executing the translated text can be defined here. In the example of FIG. 3, a process for executing a process while ignoring a specific interrupt signal is described. The description of the language-dependent preprocessing depends on the script language to be generated.

  The batch language-dependent preprocessing is a part in which preprocessing unique to the batch system is described using a script language. Each batch system has a part in which the operation is different, and a process for absorbing the difference in the operation is described here. Specifically, the operation of a general batch system is assumed to be a standard operation, and the operation that is lacking in the batch system to be generated is described here.

  For example, one batch system automatically moves to a working directory when a batch script is executed, while another batch system needs to describe a process for moving to a working directory in a batch script. In some batch systems, files necessary for processing are automatically transferred. In some batch systems, it is necessary to describe processing for moving files in a batch script. In the example of FIG. 3, the process of moving to the working directory is described using a script language. The content of the batch language dependent pre-processing depends on the batch system to be generated, and the expression format of the processing content depends on the script language.

  The text is the part that describes the target process of the batch. Specifically, the result of translating the text of the batch definition data into the script language to be generated is described here. The description of the text depends on the script language to be generated.

  The batch language dependent post-processing is a part in which post-processing specific to the batch system is described using a script language. As with batch language-dependent preprocessing, the operation of a general batch system is assumed to be a standard operation, and the operation that is lacking in the batch system to be generated is described here. In the example of FIG. 3, a process for setting a character string indicating a processing result in an environment variable is described using a script language. The content of the batch language dependent post-processing depends on the batch system to be generated, and the expression format of the processing content depends on the script language.

  The language-dependent post-processing is a part describing post-processing specific to the script language. Depending on the script language, there may be routine processing that should be performed after executing other processing, and such processing is described here. In the example of FIG. 3, a process for receiving an interrupt signal again is described. The description of the language-dependent preprocessing depends on the script language to be generated.

  FIG. 4 is a sample diagram illustrating an example of job definition data received by the job input device 200 according to the present embodiment. As shown in the figure, the job definition data received by the job input device 200 includes an attribute and a text.

  The attribute is a part that describes a generalized parameter for using the function of the batch system. As already explained, many batch systems have a function to transfer files necessary for processing and a function to send and notify when an error occurs, which is necessary to use these functions. This information is described here.

  If the batch system to be generated does not have a function corresponding to the parameter specified here, a process for supplementing the function is described in the batch language dependent pre-processing or batch language dependent post-processing of the generated batch script. For example, in the example of FIG. 4, the input files required for processing are described as attributes, but if the batch system to be generated does not have a function to transfer files, these files are transferred to batch language dependent preprocessing. The processing to be performed is described.

  In the attribute, either or both of the batch system and the script language for generating the batch script can be explicitly specified. When this designation is made, the server selection unit 230 selects a server in consideration of satisfying the designated condition.

  The main text describes the processing to be executed by the job. Since this part is translated into a plurality of script languages, it is described in a script language having a minimum necessary function. The script language describing the text may be based on the grammar of an existing script language or may be a completely new script language.

  Here, an example is shown in which the attribute and the text are provided together, but these may be provided separately.

  Next, the configuration of the batch driver module constituting the batch driver 430 will be described. FIG. 5 is a block diagram showing the configuration of the batch driver module. As shown in the figure, the batch driver module 431 includes a batch-dependent pre-processing output unit 431a, a batch language-dependent pre-processing output unit 431b, a batch language-dependent post-processing output unit 431c, and an input command output unit 431d. .

  There is one batch driver module 431 for each batch system, but all have the same configuration, and the process can be called using the same interface.

  The batch-dependent preprocessing output unit 431a receives the attribute data described in the job definition data as input, extracts and formats the attribute data that can be used as a parameter in the batch system, and performs batch-dependent preprocessing on the batch script. A processing unit that outputs a corresponding character string.

  The batch language dependent preprocessing output unit 431b receives the attribute data described in the job definition data as an input, calls the function of the language translation unit 461d of the language driver module, and writes the necessary description for the batch language dependent preprocessing of the batch script. Is a processing unit for outputting. The batch language dependent post-processing output unit 431c receives as input the attribute data described in the job definition data, calls a function of the language translation unit 461d of the language driver module, and a description necessary for batch language dependent post-processing of the batch script Is a processing unit for outputting.

  Note that the batch driver module 431 can also be configured as an object based on object-oriented technology. In that case, development efficiency can be improved by using the template function and the interface function as a template and further effectively utilizing the inheritance mechanism.

  The input command output unit 431d is a processing unit that outputs a command for inputting the generated batch script to the batch system. The batch script submission command is different for each batch system, but when the submission command output unit 431d generates the submission command, the script submission unit 250 submits the batch script without being aware of the difference in the batch system. be able to. The input command output unit 431d also generates a definition file if necessary for inputting a batch script.

  Next, the configuration of the language driver module constituting the language driver 460 will be described. FIG. 6 is a block diagram showing the configuration of the language driver module. As shown in the figure, the language driver module 461 includes an activation instruction output unit 461a, a language-dependent pre-processing output unit 436b, a language-dependent post-processing output unit 461c, and a language translation unit 461d.

  There is one language driver module 461 for each script language, but all have the same configuration, and the process can be called using the same interface.

  The activation instruction output unit 461a is a processing unit that outputs a character string corresponding to an activation instruction of a batch script. The language-dependent preprocessing output unit 461b is a processing unit that outputs a description necessary for language-dependent preprocessing of a batch script. The language-dependent post-processing output unit 461c is a processing unit that outputs a description necessary for batch language-dependent post-processing of a batch script.

  Based on the attribute information described in the job definition data, the language translation unit 461d uses a batch language-dependent preprocessing output unit 431b to express preprocessing and postprocessing specific to the batch system in the script language to be generated. Used from the batch language dependent post-processing output unit 431c. The contents of the translation process are mainly character string conversion and control structure conversion.

  Each script language for describing a batch script has a different character string description format. For example, in one script language, a lexical character enclosed by double quotations is a character string, and in another script language, a lexical character enclosed by single quotations is a character string. Depending on the script language, everything except the control phrase is treated as a character string.

  In addition, a character such as a backslash in a character string may have a special meaning, and a so-called escape process for adding another character may be necessary to cancel the effect. The language translation unit 461d reflects such a difference in the description format of the character string in the output.

  In addition, the script languages for describing batch scripts have different control structures. For example, the format such as conditional branching and repetition differs for each script language, so conversion is performed according to the language specification of the script language.

  By the way, the implementation of the batch language dependent pre-processing output unit 431b and the batch language dependent post-processing output unit 431c of the batch driver module is not always described correctly. If the implementation is incorrect, it is desirable that the language translation unit 461d can find it at the stage of translation, not at the stage of executing the batch file on the server.

  In order to enable the language translation unit 461d to detect a grammatical error in the text, the language translation unit 461d may have a powerful syntax checking function, or a character corresponding to the processing process using object-oriented technology. A column class may be defined and inspected so that an invalid character string class character string is not output to the batch script.

  In the case of the latter method, for example, it is possible to find an error in the text by performing the following processing. First, we define three string classes, “untranslated string”, “translation process string”, and “translated string”, and parse the body text described in the job definition data. Each element of is converted to "untranslated string". Then, the translation is advanced from the leaf part of the syntax tree, and the part where the translation is completed is type-converted to “character string after translation”, and the part in the middle of translation is type-converted to “character string in translation process”. Thus, if all types other than “translated character string” remain when all the translations are completed, there is an error in the text.

  The language driver module 461 can also be configured as an object based on object-oriented technology. In that case, development efficiency can be improved by using the template function and the interface function as a template and further effectively utilizing the inheritance mechanism.

  Next, the processing procedure of the script generation program 400 will be described. FIG. 7 is a flowchart showing a processing procedure of the script generation program 400. As shown in the figure, first, the batch driver selection unit 410 selects a batch driver module corresponding to the designated batch system file name from the batch driver table 420 (step S101). Subsequently, the language driver selection unit 440 selects a language driver module corresponding to the designated script language name from the language driver table 450 (step S102).

  If the batch driver module 431 and the language driver module 461 are selected, first, the activation instruction output unit 461a of the language driver module 461 outputs an activation instruction to the batch script (step S103). Subsequently, the batch dependence preprocessing output unit 431a of the batch driver module 431 outputs the batch dependence preprocessing (step S104), and the language dependence preprocessing output unit 461b of the language driver module 461 outputs the language dependence preprocessing (step S104). S105).

  Then, the batch language dependent preprocessing output unit 431b of the batch driver module 431 calls the language translation unit 461d to output the batch language dependent preprocessing (step S106), and the language translation unit 461d of the language driver module 461 translates the text. And output (step S107). Then, the batch language dependent post-processing output unit 431c of the batch driver module 431 calls the language translation unit 461d to output the batch language dependent post-processing (step S108), and the language dependent post-processing output unit 461d of the language driver module 461 The language-dependent post-processing is output, and the output of the batch script is completed (step S109).

  When the output of the batch script is completed, the input command output unit outputs a batch input command for executing the batch script to the command file, and the series of processing is completed (step S110).

  In the above description, in the process of generating the batch script, the batch driver module 431 calls the function of the language driver module 461. However, the information may be transferred using an intermediate file.

  Specifically, the batch driver module 431 generates an intermediate file in which the contents to be output in the batch language dependent preprocessing and batch language dependent postprocessing of the batch script are described in some language, and the language driver module 461 generates the intermediate file. The contents read and described are translated into a script language to be generated and output.

  By eliminating the calling relationship between the modules in this way, the section between the modules becomes clear, and when a malfunction occurs, it is possible to easily determine which module is the cause. Note that the script output to the intermediate file may be described in the same script language as the body of the job definition data, or may be described in another script language.

  As described above, in this embodiment, a script is generated by combining a batch driver module that processes a script generation rule that depends on a batch system and a language driver module that processes a script generation rule that depends on a script language. Therefore, it is possible to dynamically generate a batch script suitable for the execution environment.

  In addition, batch driver modules are prepared for each batch system, and language driver modules are prepared for each script language, so even if it becomes necessary to support a new batch system or script language, the batch system or script language is also supported. Just add the modules you have added.
