Abstract

In an information processing system running under two different operating systems (OS), a job entry unit enters a control program of a job, which is executed by the second operating system, via the first operating system. A language conversion/transfer unit converts the control program into a program for the second operating system, and transfers it to the second operating system. A data conversion/transfer unit mutually performs conversion and a transfer between files used for the first operating system and files used for the second operating system. A job execution unit executes the program for the second operating system using transferred data included in the files used for the second operating system. Thus, a user can execute the job without being conscious of differences between the operating systems.

Claims

1. An inter-OS job execution system, in which a first processor running under a first operating system requests a second processor running under a second operating system different from the first operating system to execute a job including one or more job steps, said inter-OS job execution system comprising:

job entry means for entering first information to the first processor to execute a program in the first operating system, the first information being in a language recognizable by the first operating system;

language conversion/transfer means for converting the entered first information into second information to execute the program in the second operating system in the second processor, the second information being in a language recognizable by the second operating system and different from the language recognizable by the first operating system, the second information including information of a file environment specified by the first information, for transferring the second information to the second processor, and for generating the file environment in the second processor;

data conversion/transfer means for mutually performing a conversion and a transfer between a file used by the first processor and a file used by the second processor, the file used by the second processor being in the file environment; and

job execution means for executing a program specified by the second information, which is transferred by said language conversion/transfer means, using data transferred by said data conversion/transfer means from the first processor to the second processor.

2. The inter-OS job execution system according to claim 1, wherein the first processor includes a job invocation means for instructing said job execution means embedded in the second processor to execute the program specified by the second information, and said job execution means executes the program specified by the second information according to an instruction given by said job invocation means.

3. The inter-OS job execution system according to claim 1, further comprising an output means for outputting a process result,

wherein said job execution means outputs an execution result of the program specified by the second information;

wherein said data conversion/transfer means converts contents of the execution result and transfers the contents to the first processor; and

wherein said output means outputs the contents as the process result.

4. The inter-OS job execution system according to claim 1,

wherein said job entry means enters a control program for controlling a job to the first processor as the first information;

wherein said language conversion/transfer means converts the control program into a program for the second processor and transfers the second information including the program for the second processor to the second processor; and

wherein said job execution means executes the program for the second processor.

5. The inter-OS job execution system according to claim 4,

wherein said job entry means enters the control program described in a job control language to the first processor;

wherein said language conversion/transfer means generates a job environment specified by the control program, the job environment including the information of the file environment, and transfers the second information including the job environment to the second processor;

wherein said data conversion/transfer means converts a file included in the job environment and transfers the file to the second processor; and

wherein said job execution means references the file included in the file environment and executes the program for the second processor.

6. The inter-OS job execution system according to claim 1,

wherein said job entry means enters the control program for controlling the job, which includes a program for the second processor, to the first processor as the first information;

wherein said language conversion/transfer means extracts the program for the second processor from the control program, and transfers the second information including the program for the second processor to the second processor; and

wherein said job execution means executes the program for the second processor.

7. A first processor, for use in an inter-OS job execution system, running under a first operating system, and requesting a second processor running under a second operating system different from the first operating system to execute a job including one or more job steps, said first processor comprising:

job entry means for entering first information to execute a program in the first operating system, the first information being in a language recognizable by the first operating system;

language conversion/transfer means for converting the first information into second information to execute the program in the second processor, the second information being in a language, recognizable by the second operating system and different from the language recognizable by the first operating system, the second information including information of a file environment specified by the first information, for transferring the second information to the second processor, and for generating the file environment in the second processor; and

data conversion/transfer means for converting data used to execute the program specified by the second information into data for the second processor, and transferring converted data to the file environment in the second processor.

8. The first processor according to claim 7, further comprising job invocation means for instructing the second processor to execute the program specified by the second information.

9. A second processor, for use in an inter-OS job execution system in which a first processor running under a first operating system requests said second processor running under a second operating system different from the first operating system to execute a job including one or more job steps, said second processor comprising:

reception means for receiving information to execute a program in the second operating system from the first processor, the information being in a language, recognizable by the second operating system and different from a language recognizable by the first operating system, the information including information of a file environment for the job, and for generating the file environment in the second processor; and

job execution means for executing the program specified by the information using data transferred for the first processor, the data being in the file environment.

10. The second processor according to claim 9, wherein said job execution means executes the program according to an instruction given by the first processor.

11. An inter-OS job execution system, in which a first operating system requests a second operating system to execute a job including one or more job steps, said inter-OS job execution system comprising:

job entry means for entering first information to execute a program in the first operating system, the first information being in a language recognizable by the first operating system;

language conversion/transfer means for converting the first information into second information to execute the program in the second operating system, the second information being in a language, recognizable by the second operating system and different from the language recognizable by the first operating system, the second information including information of a file environment specified by the first information, for transferring the second information to the second operating system, and for generating the file environment under the second operating system;
