Appl. No.:

11/338560

Inventors:

Berry A. Cobb - Scottsdale AZ, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 15/16

US Classification:

709206, 709224

Abstract:

A method and system for reporting availability of a plurality of servers. The method comprises the steps of for each of said plurality of servers, periodically searching a log file for indication of a crash or shutdown or start, computing the time said crash or shutdown or start occurred, and sending said time and indication as an e-mail to a database on a server. The method further comprises the steps of calculating the duration of downtime for each said crash or said shutdown; for each server, sorting said e-mail by order received; and displaying for each of said plurality of servers, said duration of downtime in said order. For example, the sending step includes the step of sending said e-mail to a database on a pre-identified one server; and the sorting step includes the step of sorting said e-mail by order received by said pre-identified one server. Also, with a preferred embodiment, each of the plurality of servers includes an e-mail function; and the sending step includes the step of, each server using its e-mail function to send the time and indication to said database.

International Classification:

G06F009/46

US Classification:

718100000

Abstract:

A system, method and program for scheduling a program for periodic execution. The program requires a computer resource for execution. The historic utilization or 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 specific time and daily thereafter at the specific time or weekly or monthly thereafter on the day at the specific time. In response, the record of the historic utilization or availability of the resource is checked for the day at approximately the specific time to determine if there has been sufficient availability or a predetermined minimum amount of availability of the resource in the past on the day at approximately the specific time. If so, the program is scheduled for execution on the day and specific time and daily thereafter at the specific time or weekly or monthly thereafter on the day at the specific time as requested. If not, the program is not scheduled for execution on the day at the specific time. Also, another time on the specific day close to specific time is automatically determined when there was sufficient availability of the resource in the past to execute the program. Then, an operator is notified of the other time on the day. The operator indicates whether the other time on the day is acceptable. If so, the program is scheduled for execution at the other time on the day and daily thereafter at the other time or weekly or monthly thereafter on the day at the other time.

International Classification:

G06F 9/48
G06F 9/50

Abstract:

A method and computer system for scheduling, for periodic execution, a program requiring a computer hardware resource for execution. A processor of the computer system receives a request to schedule the program for execution on a day at a specified time and periodically thereafter at the specified time, and in response, the processor determines if there was historical availability of the resource exceeding a predetermined availability threshold on the day at approximately the specified time to execute the program, and if so, schedule the program for execution on the day at the specified time and periodically thereafter, and if not, not schedule the program for execution on the day at the specified time periodically. In response to a determination of no historical availability of the resource at approximately the specified time, the processor automatically determines another time on the day during which there was historical availability of the resource.

US Classification:

718104

Abstract:

A method and system for scheduling, for periodic execution, a program requiring a computer hardware resource for execution. A computer determines and records historic utilization or availability of the resource multiple times a day. The computer subsequently receives a request to schedule the program for execution on the day at a specified time and (a) daily, (b) weekly, or (c) monthly at the specified time, and in response, the computer determines if there has been historical availability of the resource exceeding a predetermined availability threshold on the day at approximately the specified time to execute the program, and if so, schedule the program for execution on the day at the specified time and (i) daily, (ii) weekly, or (iii) monthly thereafter, as requested, and if not, not schedule the program for execution on the day at the specified time or (i) daily, (ii) weekly, or (iii) monthly thereafter, as requested.
