Abstract

A job scheduling system to execute plural jobs in an information system including plural computers for which an operation procedure is defined in the job flow format inputs a logical system configuration definition representing an architecture of the information system, sets a parameter for each job of the job flow according to the logical system configuration definition, and then executes the job flow. The system configuration definition defines a logical configuration of the information system according to data models to describe the system to thereby control the correspondence between defined logical servers and physical servers in the real world in a centralized manner. Using the information of the system configuration definition, the job scheduling system defines a parameter for each job of the job flow.

Claims

1. A computer control method for use with a control computer which reads a command to execute a program stored in advance and which sends the command to a plurality of physical computers to thereby control the physical computers, wherein the control computer:

beforehand stores logical computer names respectively of the plural physical computers with a correspondence established between the physical computers and the logical computer names;

analyzes the command including the logical computer name of one of logical computers which executes the command; and

transmits the command thus analyzed to each of the physical computers corresponding to the logical computer name.

3. The computer control method according to claim 1, wherein if a parameter of the command includes the logical computer name, the parameter is converted into the plural physical computer names corresponding to the logical computer name and each of the commands thus converted is transmitted to the physical computers associated with the physical computer names.

2. A computer control method for use with a computer system comprising a plurality of physical computers which each receives a command to execute a program and which each executes the program and a control computer which transmits the command to the physical computers to control the physical computers, wherein the control computer:

beforehand stores physical computer names respectively of the plural physical computers with a correspondence established between the physical computer names and computer types;

analyzes the command including a computer type of one of logical computers which executes the command; and

transmits the command thus analyzed to each of the physical computers corresponding to the computer type.

4. The computer control method according to claim 2, wherein if a parameter of the command includes the logical computer name, the parameter is converted into the plural physical computer names corresponding to the logical computer name and each of the commands thus converted is transmitted to the physical computers associated with the physical computer names.

5. A control computer which reads a command to execute a program stored in advance and which sends the command to a plurality of physical computers to thereby control the physical computers, comprising:

a module for beforehand storing logical computer names respectively of the plural physical computers with a correspondence established between the physical computers and the logical computer names;

a module for analyzing the command including the logical computer name of the logical computer which executes the command; and

a module for transmitting the command thus analyzed to each of the physical computers corresponding to the logical computer name.

6. A control program to be executed by a control computer which reads a command to execute a program stored in advance and which sends the command to a plurality of physical computers to thereby control the physical computers, comprising:

a step of beforehand storing logical computer names respectively of the plural physical computers with a correspondence established between the physical computers and the logical computer names;

a step of analyzing the command including the logical computer name of the logical computer which executes the command; and

a step of transmitting the command thus analyzed to each of the physical computers corresponding to the logical computer name.

7. A job flow setting method of setting a job flow for a job scheduling system which defines for an information system including a plurality of computers an operation procedure in a format of a job flow to execute the operation procedure, comprising the steps of:

inputting system configuration information representing a configuration of the information system;

inputting partial information of the system configuration information, as a parameter of a job included in the job flow; and

establishing at execution of the job flow a correspondence between the partial information contained in the parameter and physical information required to execute the job, according to the system configuration information.

8. The job flow setting method according to claim 7, wherein the system configuration information includes a correspondence relationship between logical resources and physical resources.

9. The job flow setting method according to claim 7, further comprising the step of receiving a type of the logical resources as a parameter to be inputted thereto.

10. The job flow setting method according to claim 8, wherein:

the logical resources are logical servers; and

the physical resources are physical servers.

11. The job flow setting method according to claim 9, wherein if the parameter is a type of the logical resources, a correspondence is established between at least one of the logical resources belonging to the type and each of the physical resources associated with the logical resource.

17. A computer-readable storing medium having stored a program to execute the job flow setting method according to claim 7.

12. A job flow execution method for use with a job scheduling system which defines for an information system including a plurality of computers an operation procedure in a format of a job flow to execute the operation procedure, comprising the steps of:

keeping system configuration information representing a configuration of the information system, the system configuration information being inputted in advance; and

establishing at execution of each job according to the job flow a correspondence between partial information of the system configuration information and physical information required to execute the job, the partial information being beforehand inputted as a parameter of the job.

13. The job flow execution method according to claim 12, wherein the system configuration information also includes a correspondence relationship between logical resources and physical resources.

14. The job flow execution method according to claim 12, further comprising the step of receiving a type of the logical resources as a parameter to be inputted thereto.

15. The job flow execution method according to claim 13, wherein:

the logical resources are logical servers; and

the physical resources are physical servers.

16. The job flow execution method according to claim 12, wherein if the parameter is a type of the logical servers, the job is executed by physical servers corresponding to at least one of the logical servers belonging to the type.

18. A computer-readable storing medium having stored a program to execute the job flow executing method according to claim 12.
