Abstract: A method, a medium, and a system for distributing a warehouse task from a warehouse management hub to a programmable logic controller comprise receiving at least one warehouse task at a warehouse management hub including attributes for physically transferring at least one product into a warehouse, out of the warehouse or within the warehouse, determining, by the warehouse management hub and based on the attributes of the warehouse task, one of a plurality of warehouse management devices for processing the warehouse task, sending, by the warehouse management hub, the warehouse task to the determined warehouse management device, identifying, by the determined warehouse management device and based on the attributes of the warehouse task, a first one of a plurality of programmable logic controllers, and sending, by the determined warehouse management device, a message including information for carrying out the warehouse task to the identified programmable logic controllers.

Abstract: A system and process that manages access to a resource in an enterprise service-oriented architecture environment. The system recognizes a master for each resource that has ultimate control over the respective resource. The master grants access to the resource though a lock system. If a system does not relinquish access to the resource, then the master is able to reclaim the lock to ensure the continued availability of the resource to all systems. This system ensures data coherency, while also improving performance by diminishing the amount of time a resource is unnecessarily locked and the time to obtain a lock.

Abstract: A time slot of regular time length and capacity is defined in time local to a time zone. The slot is defined by a local time start timestamp and a local time end timestamp. In one aspect, upon determining that the local time end timestamp of the slot overlaps with the transition period, the time slot is prolonged beyond the transition period. The prolonged time slot is correspondingly defined by an international standard time start timestamp and an international standard time end timestamp. The prolonged time slot is generated based on the international standard time start timestamp and the international standard time end timestamp.

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.
