Abstract: A request to calculate workload for a number of time buckets is received. In response to the request, one or more sets of activities with equal execution timeframe are determined. In one aspect, for the one or more sets of activities, net execution duration of activities from the one or more sets of activities is aggregated to determine workloads of the one or more sets of activities. Planned work time consumption of the determined workloads is calculated. In one aspect, calculated planned work time consumption of the workloads is distributed across the number of time buckets. Distributed planned work time consumption of the workloads is aggregated, by the time buckets to calculate the workload for the time buckets.

Abstract: A system and method of updating persistent objects in a persistent store. In response to receipt of a confirmation of task competition, an attempt is made to acquire a lock for corresponding item data in the persistent store. Regardless of whether the lock is acquired, a successful update of the persistent store is acknowledged to the sender of the confirmation within a defined time period.
