Abstract

A server acquires data representing the number of jobs on the daily and hourly basis for several weeks held by itself and by clients. An apparatus for executing scheduling calculates the total number of jobs on the daily basis from the acquired data representing the number of jobs on the daily and hourly basis for several weeks and determines the order in ascending order of the total number of jobs on the daily basis. The apparatus searches for a time period with long idle time sequentially from the day with the minimum total number of jobs. Regarding the target day to search for a time period with long idle time, it is determined whether a time period of 3 consecutive hrs without job is present. If a time period of 3 consecutive hrs without job is present, the middle time of the time period is scheduled as a firmware update time period, and firmware update is registered.

Claims

1. A server apparatus for transmitting data necessary for program update to a client apparatus comprising:

an acquisition unit configured to acquire, from said client apparatus, job execution status representing the status of jobs executed in each of a plurality of periods of time by said client apparatus; and

a scheduling unit configured to determine a schedule of program update in said client apparatus on the basis of the job execution status acquired by said acquisition unit.

2. The apparatus according to claim 1, wherein said scheduling unit detects one of a period of time with minimum job execution and a period of time without job execution in said client apparatus on the basis of the job execution status acquired by said acquisition unit, and determines the schedule of program update on the basis of the detected time.

3. The apparatus according to claim 2, wherein

said acquisition unit acquires the job execution status from each of a plurality of client apparatuses, and

said scheduling unit determines the schedule of program update in each of the plurality of client apparatuses on the basis of the job execution status acquired from the plurality of client apparatuses by said acquisition unit not to make the plurality of client apparatuses execute program update in the same period of time.

4. The apparatus according to claim 1, further comprising a transmission unit configured to transmit data necessary for program update in said client apparatus in accordance with the schedule of program update determined by said scheduling unit.

5. A apparatus according to claim 1, wherein the job execution status representing the number of jobs executed in each of a plurality of periods of time by said client apparatus.

6. A data processing system having a client apparatus for executing a job and a server apparatus for transmitting data necessary for program update to said client apparatus,

said server apparatus comprising:

an acquisition unit configured to acquire, from said client apparatus, job execution status representing the status of jobs executed in each of a plurality of periods of time by said client apparatus;

a scheduling unit configured to determine a schedule of program update in said client apparatus on the basis of the job execution status acquired by said acquisition unit; and

a transmission unit configured to transmit data necessary for program update to said client apparatus in accordance with the schedule of program update determined by said scheduling unit, and

said client apparatus comprising;

a storage unit configured to store the job execution status;

a reception unit configured to receive the data necessary for program update from said server apparatus; and

an update unit configured to execute program update on the basis of the data received by said reception unit when no job is being executed.

7. The system according to claim 6, wherein said client apparatus further comprises a notification unit configured to notify said server apparatus of an end of program update when program update is ended.

8. The system according to claim 6, wherein if said client apparatus is executing a job at the time of data reception by said reception unit, said update unit executes program update after the job that is being executed is ended.

9. The system according to claim 6, wherein if said client apparatus is executing a job at the time of data reception by said reception unit, said update unit requests said server apparatus to reschedule program update.

10. The system according to claim 6, wherein said client apparatus comprises a first return unit configured to return said second data processing apparatus from a power saving state in accordance with the schedule determined by said scheduling unit.

11. The system according to claim 6, wherein said client apparatus comprises a second return unit configured to return said first data processing apparatus from a power saving state in accordance with the schedule determined by said scheduling unit.

12. The system according to claim 6, wherein the job execution status representing the number of jobs executed in each of a plurality of periods of time by said client apparatus.

13. A data processing method for a server apparatus for transmitting data necessary for program update to a client apparatus, comprising the steps of:

acquiring, from said client apparatus, job execution status representing the status of jobs executed in each of a plurality of periods of time by said client apparatus; and

determining a schedule of program update in said client apparatus on the basis of the job execution status acquired in the acquiring step.

14. The method according to claim 13, wherein in the scheduling step, one of a period of time with minimum job execution and a period of time without job execution in said client apparatus is detected on the basis of the job execution status acquired in the acquiring step, and the schedule of program update is determined on the basis of the detected time.

15. The method according to claim 13, wherein

in the acquiring step, the job execution status is acquired from each of a plurality of client apparatuses, and

in the scheduling step, the schedule of program update in each of the plurality of client apparatuses is determined on the basis of the job execution status acquired from the plurality of client apparatuses in the acquiring step not to make the plurality of client apparatuses execute program update in the same period of time.

16. The method according to claim 13, further comprising the step of transmitting data necessary for program update in said client apparatus in accordance with the schedule of program update determined in the scheduling step.

17. The method according to claim 13, wherein the job execution status representing the number of jobs executed in each of a plurality of periods of time by said client apparatus.

18. A computer-readable storage medium storing a computer program for a server apparatus for transmitting data necessary for program update to a client apparatus, comprising:

an acquisition module which acquires, from said client apparatus, job execution status representing the status of jobs executed in each of a plurality of periods of time by said client apparatus; and

a scheduling module which determines a schedule of program update in said client apparatus on the basis of the job execution status acquired by said acquisition module.

19. The medium according to claim 18, wherein said scheduling module detects one of a period of time with minimum job execution and a period of time without job execution in said client apparatus on the basis of the job execution status acquired by said acquisition module, and determines the schedule of program update on the basis of the detected time.

20. The medium according to claim 18, wherein

said acquisition module acquires the job execution status from each of a plurality of client apparatuses, and

said scheduling module determines the schedule of program update in each of the plurality of client apparatuses on the basis of the job execution status acquired from the plurality of client apparatuses by said acquisition module not to make the plurality of client apparatuses execute program update in the same period of time.

21. The medium according to claim 18, further comprising a transmission module which transmits data necessary for program update in said client apparatus in accordance with the schedule of program update determined by said scheduling module.

22. The medium according to claim 18, wherein the job execution status representing the number of jobs executed in each of a plurality of periods of time by said client apparatus.
