Abstract

A system and method can support batch job management in a distributed system using a queue system with a plurality of queues and one or more job management servers. The queue system can represent a life cycle for executing a job by a job execution component, with each queue in the queue system adapted to receive one or more messages that represent a job status in the life cycle for executing the job. The one or more job management servers in the distributed system can direct the job execution component to execute the job, with each job management server monitoring one or more queues in the queue system, and performing at least one operation on the one or more messages in the queue system corresponding to a change of a job status for executing the job.

Claims20

Dependent claims

A system to support job management of a plurality of jobs described in job script files in an initial language, comprising:

a distributed system comprising a job execution component operating on a plurality of microprocessors;
a job administration server wherein the job administration server is operative to receive each job script file and, in response to each job script file, create a separate lob message associated with each job script file;
a queue system in the distributed system wherein the queue system includes at least a conversion queue, an execution-waiting queue, and an executing queue;
a job converter in the distributed system that monitors the conversion queue, where the job converter is operative to
select a job message from the conversion queue,
direct the job execution component to convert the job script file associated with said job message into a converted job script file in a conversion script language different than the initial language, and
then move said job message to the execution-waiting queue;
and
a job initiator in the distributed system that monitors the execution-waiting queue, wherein the job initiator is operative to
select a job message from the execution-waiting queue,
direct the job execution component to execute a converted job script file associated with said job message, and
move said job message from the execution-waiting queue into the executing queue.

9 more elements

A method for supporting management of execution of a plurality of job script files, in a distributed system having a job execution component operating on a plurality of microprocessors, comprising:

providing a queue system in said distributed system which includes at least a conversion queue, an execution-waiting queue, and an executing queue;
providing a job administration server wherein the job administration server is operative to receive each job script file and, in response to each job script file, create a separate job message associated with each job script file;
providing a job converter in said distributed system that monitors the conversion queue and performs
selecting a job message from a conversion queue,
allowing the job execution component to perform job script conversion work on the job script file associated with the selected job message, and
putting the selected job message in an execution waiting queue after the job script conversion work is done;
and
providing a job initiator in said distributed system that monitors the execution-waiting queue and performs
selecting a job message from the execution-waiting queue,
invoking the job execution component to run the job script file associated with the selected job message, and
moving the selected job message from the execution-waiting queue into the executing queue.
