Abstract

A non-transitory computer-readable recording medium storing a program causing a computer to execute a process, the process includes starting N (two or more) processes from a first program; and controlling variation in the number of processes for which a second program is deployed, depending on a load on the processes for which the second program is deployed, within a range of the N processes by deploying the second program to a storage area corresponding to one process of the N processes and undeploying the second program deployed to the storage area.

First claim

What is claimed is:

1. A non-transitory computer-readable storage medium storing a program causing a computer to execute a process, the process comprising:
starting N (two or more) processes from a first program; and
controlling variation in a number of processes for which a second program is deployed, depending on a load on the processes for which the second program is deployed, within a range of the N processes by deploying the second program to a storage area corresponding to one process of the N processes and undeploying the second program deployed to the storage area.

2. The storage medium according to claim 1 , wherein
the starting of the N processes includes starting a set number of processes, and the set number is set in advance.

3. The storage medium according to claim 2 , wherein
the controlling of variation in the number of processes includes controlling variation in the number of processes for which the second program is deployed in such a way that the number of processes is increased or decreased by a variation number set in advance.

4. The storage medium according to claim 2 , the process further comprising
monitoring the number of the processes for which the second program is deployed, at given time points, wherein
the controlling of a change in the number of processes includes
controlling variation in the number of processes so that the number of processes is increased or decreased by a variation number determined based on a difference between a first result of monitoring the number of processes and a second result of monitoring at a monitoring time point previous to the monitoring of the first result.

5. The storage medium according to claim 3 , wherein
there are a plurality of types of the second programs, and
the variation number is set for each type of the second program.

6. The storage medium according to claim 1 , the process further comprising
monitoring the load at given time points, wherein
the controlling of a change in the number of processes includes
controlling variation in the number of processes so that the number of processes is increased or decreased by the variation number determined based on a comparison between a first result of monitoring the load and a second result of monitoring at a monitoring time point previous to monitoring of the first result.

7. The storage medium according to claim 1 , the process further comprising
monitoring the load at a given cycle, wherein
the controlling of variation in the number of processes includes controlling variation in the number of processes at the given cycle.

8. The storage medium according to claim 1 , wherein
the N processes are execution bases shared by a plurality of types of programs for supporting different services.

9. The storage medium according to claim 1 , wherein
the starting of N processes includes starting the N processes before receiving a service request from a client terminal.

10. The storage medium according to claim 1 , the process further comprising
detecting the load based on the number or proportion of the processes during execution of processing related to a service request among the N processes.

11. An information processing method performed by a computer, comprising:
starting N (two or more) processes from a first program; and
controlling variation in a number of processes for which a second program is deployed, depending on a load on the processes for which the second program is deployed, within a range of the N processes by deploying the second program to a storage area corresponding to one process of the N processes and undeploying the second program deployed to the storage area.

12. An information processing device, comprising:
a memory; and
a processor coupled to the memory and configured to:
start N (two or more) processes from a first program, and
control a change in a number of processes for which a second program is deployed, depending on a load on the processes for which the second program is deployed, within a range of the N processes by deploying the second program to a storage area corresponding to one process of the N processes and undeploying the second program deployed to the storage area.
