Abstract

Arrangements for scheduling execution of jobs on target entities of a data processing system are disclosed. A plan can be stored that defines a flow of execution of a set of jobs. Each job can be executed on a selected target entity or a qualified entity such as a workstation with the appropriate configuration according to the plan. A set of rules may be utilized to invoke one or more actions in response to a detection of an event. Each target entity can detect one or more events. The execution of each action on a corresponding action target entity can be triggered based on a detected event.

Claims

1. A method comprising:

storing a plan, the plan defining a flow of execution of a set of jobs and defining entities to execute the set of jobs;

selecting a target entity to execute at least one job in the set of jobs;

submitting the at least one job in the set of jobs to the selected target entity and executing the at least one job in response to the plan;

storing at least one rule, the at least one rule defining a relationship between an event and at least one action, the at least one action to be executed in response to the detected event;

detecting an event during an execution of the plan; and

utilizing the at least one rule associated with the detected event to facilitate execution of the at least one action.

2. The method of claim 1 wherein the at least one of the action comprises submitting an unplanned job that is not present in the plan to an action target entity, the unplanned job to be executed on an action target entity.

3. The method of claim 1 further comprising running an event detection module on the target entity to detect an event on the target entity.

4. The method of claim 1 further comprising checking a version of configuration parameters loaded on the selected target entity and updating the configuration parameters if the configuration parameters are not current and forgoing updating of the configuration parameters if the configuration parameters are current.

5. The method of claim 4 wherein checking comprises transmitting a configuration parameter version indicator to the selected target entity and comparing the configuration parameter version indicator with a stored indicator from a previous configuration parameter version indicator.

6. The method of claim 1 wherein the execution of the action comprises identifying an action target entity based on rules associated with the event, and submitting the action for execution on the action target entity.

7. The method of claim 1 further comprising detecting a change in the rules that affect the target entity and providing a new set of rules to the target entity based on the detected change.

8. The method of claim 7 wherein detecting the change to the rules that affects the target entity is provided by an event detection module loaded on the target entity.

9. A computer program product comprising a computer readable storage medium including instructions that, when executed by a processor:

provide a plan defining a flow of execution of a set of jobs;

select a target entity to execute a job from the set of jobs;

execute the job utilizing the selected target entity according to the plan;

detect an event related to the execution of the job;

utilize a set of rules, each rule defining an action to be executed on an action target entity in response to the detection of the event; and

execute an action on a target entity in response to the detection of the corresponding event.

10. The computer program product of claim 9 wherein the instructions when executed by a processor comprise submitting an unplanned job that is not present in the plan to an action target entity based on the detection of an event.

11. The computer program product of claim 9 wherein the instructions when executed by a processor comprise an event detection module on the target entity and on a plurality of target entities.

12. The computer program product of claim 9 wherein the instructions when executed by a processor comprise a version of configuration parameters loaded on the selected target entity and updating the configuration parameters if the configuration parameters are not current and forgoing updating of the configuration parameters if the configuration parameters are current.

13. The computer program product of claim 9 wherein the instructions when executed by a processor comprise transmitting a configuration parameter version indicator to the selected target entity and comparing the configuration parameter version indicator with a stored indicator from a previous configuration parameter version indicator.

14. The computer program product of claim 9 wherein the instructions when executed by a processor comprise identifying an action target entity based on rules associated with the event and submitting the action for execution on the action target entity.

15. The computer program product of claim 9 wherein the instructions when executed by a processor comprise detecting a change in the rules that affect the target entity and providing a new set of rules to the target entity based on the detected change.

16. A scheduling system comprising:

a planner to provide a plan that defines a flow of execution for a job from a set of jobs;

a handler to submit the job to be executed on a target workstation in response to the plan;

an event detector to detect an event based on a set of configuration parameters;

an editor to maintain a set of rules, each rule defining an action to be executed in response to the detected event;

a monitor to monitor events defined in the rules; and

an executor to facilitate execution of the action in response to the detection of the event.

17. The scheduling system of claim 16 further comprising an executor to submit the job to be executed on the selected target entity according to the plan.

18. The scheduling system of claim 16 further comprising a rule database coupled to the editor, the rule database to store at least one rule, the at least one rule defining an action to be executed in response to the detection of the event.

19. The scheduling system of claim 16 further comprising an event monitor to trigger execution of the action in response to the detected event.

20. The scheduling system of claim 16 further comprising a processor to process an unplanned job that is undefined in the plan based on the detection of an event.
