If needed, you can execute priorized jobs by bypassing the Job Scheduler's queue. For that, according role capabilities are needed as well as cluster resources. |
To priorize a job when configuring it in the import/ export job wizard, simply mark the check box "Bypass Internal Job Queue". The job will be executed right after finishing the job wizard.
To display the check box for bypassing the Job Scheduler queue, make sure the capability "Cluster Configuration" is activated.
