Changing maintenance jobs priority
By default maintenance jobs are executed according to the sequence with which the jobs are created (First-in-First-out). Thus the priority of maintenance jobs is determined by the sequence in which jobs are executed.
To increase or decrease the priority of a maintenance job:
1. Click Configuration tab and select Options.
2. From Configurations, select Database Operations node.
3. From the right pane, right-click the maintenance job and select Increase Priority or Decrease Priority accordingly.
