Abstract

A method for supervising the execution of a job in a license restricted environment is disclosed. According to the license restricted environment, some networked machines are licensed for a first type of processing and other machines are licensed for a second (or other) types of processing. In executing a job that requires processing portions or segments of both the first and second types of processing, when the job begins processing the job using the first types of processing on a suitably licensed machine and then fails when attempting to process the job using the second types of processing on the same machine because of a license violation. The method for supervising operates in an automated fashion to detect the stoppage of the job due to license failure and to resume the remaining portions or segments of the job for processing using the second types of processing on a suitably licensed machine.

wherein said method further comprises:

(k) notifying the operator when the job has stopped before completion for some reason other than the license violation.

10. A computer-implemented method as recited in claim 7, wherein processing of the job produces a log file, and

wherein said determining (g) uses the log file to determine at what point in the job the job was stopped.

11. A computer-implemented method as recited in claim 6, wherein said method further comprises:

(k) monitoring the processing of the job on the second server machine;

(l) determining whether the job being processed on the second server machine stopped before completion due to a license violation;

(n) determining a third type of license needed to process at least a next portion of the job;

(o) selecting a third server machine to process at least the next portion of the job from the server machines having the third type of license; and

(p) submitting the job for processing on the third server machine beginning at the point in the job where the job previously stopped.
