Abstract

Scheduling a program for periodic execution. The program requires a computer resource for execution. The historic availability of the resource is determined and recorded at a multiplicity of times a day. Subsequently, a request is received to schedule a program for execution on the day at a specified time and daily thereafter at the specified time or weekly or monthly thereafter on the day at the specified time. If there has been sufficient historic availability of the resource on the day at approximately the specified time, the program is scheduled for execution on the day at the specified time and daily thereafter at the specified time or weekly or monthly thereafter on the day at the specified time as requested. If not, the program is scheduled for execution at another time on the specific day close to the specified time.

Claims

1. A method for scheduling a program for periodic execution, said program requiring a computer hardware resource for execution, said method comprising the steps of:

a computer determining and recording historic utilization or availability of said computer hardware resource at a multiplicity of times a day; and

the computer subsequently receiving a request to schedule a program for execution on said day at a specified time and (a) daily thereafter at said specified time or (b) weekly thereafter on said day of the week at said specified time, or (c) monthly thereafter on said day of the month at said specified time, and in response, the request receiving computer checking the record of the historic utilization or availability of said computer hardware resource for said day at approximately said specified time to determine if there has been sufficient historical availability of said resource on said day at approximately said specified time to execute said program, and if so, scheduling said program for execution on said day at said specified time and (i) daily thereafter at said specified time, or (ii) weekly thereafter on said day of the week at said specified time, or (iii) monthly thereafter on said day of the month at said specified time, as requested, and if not, the request receiving computer not scheduling said program for execution on said day at said specified time or (i) daily thereafter at said specified time, or (ii) weekly thereafter on said day of the week at said specified time, or (iii) monthly thereafter on said day of the month at said specified time, as requested,

wherein there was not sufficient historical availability of said computer hardware resource on said day at approximately said specified time, and in response, the request receiving computer automatically determining another time on said day within an hour of said specified time at which there was sufficient historical availability of said resource in the past to execute said program and displaying on a computer monitor a notification that said other time on said day is available to execute said program.

2. The method set forth in claim 1 wherein said computer hardware resource is one of a processor, a computer readable storage device and a random access memory.

3. The method set forth in claim 1 wherein the step of the determining and recording computer determining and recording historic utilization or availability of said computer hardware resource at a multiplicity of times a day comprises the step of the determining and recording computer determining and recording utilization or availability of said computer hardware resource every minute or less of said day.

4. The method set forth in claim 1 wherein the step of the determining and recording computer determining and recording historic utilization or availability of said computer hardware resource at a multiplicity of times a day comprises the step of determining and recording utilization or availability of said computer hardware resource every minute or less of every day of a week.

5. The method set forth in claim 1 wherein the step of the request receiving computer determining if there was sufficient historical availability of said computer hardware resource on said day at approximately said specified time, comprises the step of the request receiving computer comparing a requirement of said program for said computer hardware resource during execution of said program to the historic availability of said computer hardware resource on said day at approximately said specified time.

6. A computer program product for scheduling a program for periodic execution, said program requiring a computer hardware resource for execution, said computer program product comprising:

a computer readable non-transitory storage media;

first program instructions to determine and record historic utilization or availability of said computer hardware resource at a multiplicity of times a day; and

second program instructions to subsequently receive a request to schedule a program for execution on said day at a specified time and (a) daily thereafter at said specified time or (b) weekly thereafter on said day of the week at said specified time, or (c) monthly thereafter on said day of the month at said specified time, and in response, check the record of the historic utilization or availability of said computer hardware resource for said day at approximately said specified time to determine if there has been sufficient historical availability of said resource on said day at approximately said specified time to execute said program, and if so, schedule said program for execution on said day at said specified time and (i) daily thereafter at said specified time, or (ii) weekly thereafter on said day of the week at said specified time, or (iii) monthly thereafter on said day of the month at said specified time, as requested, and if not, not schedule said program for execution on said day at said specified time or (i) daily thereafter at said specified time, or (ii) weekly thereafter on said day of the week at said specified time, or (iii) monthly thereafter on said day of the month at said specified time, as requested;

third program instructions, in response to there not being sufficient historical availability of said computer hardware resource on said day at approximately said specified time, for determining another time on said day within an hour of said specified time at which there was sufficient historical availability of said resource in the past to execute said program and displaying on a computer monitor a notification that said other time on said day is available to execute said program, and wherein

said first, second and third program instructions are stored on said computer readable storage media.

7. The computer program product set forth in claim 6 wherein said computer hardware resource is one or more processors.

8. The computer program product set forth in claim 6 wherein said computer hardware resource is a computer readable storage device.

9. The computer program product set forth in claim 6 wherein said computer hardware resource is RAM.

10. A computer system for scheduling a program for periodic execution, said program requiring a computer hardware resource for execution, said computer system comprising:

a CPU, a computer readable memory, and a computer readable storage media;

first program instructions to determine and record historic utilization or availability of said computer hardware resource at a multiplicity of times a day; and

second program instructions to subsequently receive a request to schedule a program for execution on said day at a specified time and (a) daily thereafter at said specified time or (b) weekly thereafter on said day of the week at said specified time, or (c) monthly thereafter on said day of the month at said specified time, and in response, check the record of the historic utilization or availability of said computer hardware resource for said day at approximately said specified time to determine if there has been sufficient historical availability of said resource on said day at approximately said specified time to execute said program, and if so, schedule said program for execution on said day at said specified time and (i) daily thereafter at said specified time, or (ii) weekly thereafter on said day of the week at said specified time, or (iii) monthly thereafter on said day of the month at said specified time, as requested, and if not, not schedule said program for execution on said day at said specified time or (i) daily thereafter at said specified time, or (ii) weekly thereafter on said day of the week at said specified time, or (iii) monthly thereafter on said day of the month at said specified time, as requested;

third program instruction, in response to there not being sufficient historical availability of said computer hardware resource on said day at approximately said specified time, for determining another time on said day within an hour of said specified time at which there was sufficient historical availability of said resource in the past to execute said program and displaying on a computer monitor a notification that said other time on said day is available to execute said program, and wherein
