Sean, AFAIK WLM runs and manages continuously the workload setting DP as needed (if there's no CPU contention ... so no problems).
Its main task is to make all the AS as fast as they can. If there's available CPU for everybody every AS will take as much as it can. If you want a single (or group of) AS to be limited you can use a capping based on a Resource Group (WLM menu option 3) to set a maximum of MSUs available for that group. You have to use a classification to assign the AS to that RG too. Hope this helps. Best regards.
