Queue Management panel

Use the Queue Management to add or delete workload management queues or to modify the definition of the queues.

Only users with the DataStage and QualityStage Administrator role can configure the workload management queues. Other users of the operations console can view the definition of the queues.

If the system policies allow another job to be started, the top job in each queue that does not have its maximum number of running jobs is examined. The job with the highest priority is started. The Queue priority rule, which is used to determine the priority of a job, ensures that jobs from lower priority queues are eventually started.

Select one of these values for the Queue priority rule:

Select Job Run Ratio, and specify the High to Medium and Medium to Low ratios. The priority of a job is derived from the priority of the queue it was submitted to. The ratios determine how many jobs are started from a high priority queue before a job is started from a medium priority queue, and how many jobs are started from a medium priority queue before a job is started from a low priority queue.
Select Elapsed Time. The priority of a job is derived from the elapsed time since the job was submitted to the queue. This rule gives the highest priority to the job that was submitted first, irrespective of the queue it was submitted to.
Select Priority Weight. The priority of a job is derived from the priority of the queue it was submitted to and from the elapsed time since the job was submitted to the queue. This rule is the default rule.

The list at the bottom of the Queue Management panel shows the definition of all the workload management queues that are defined. The following actions are available:

Click New Queue to add a queue. Specify the definition of the queue.
Select a queue in the list of queues, and click Delete to delete the queue. You cannot delete certain predefined queues, and you cannot delete queues that contain jobs.
Double-click a field for one of the queues in the list to change the value of the field. The definitions of certain predefined queues cannot be changed.

Click Save to save the changes to the definition of the queues.
