• Advance Server - Advance server service enables load balancing in AVEVA Work Tasks. In an environment, ensure to disable the feature if the environment is not set for enterprise version.

• Task Scheduler - This service handles the execution of all tasks that have not taken place as scheduled (escalations). Task Scheduler does not persist any information in memory. All tasks are database persisted and are performed only when due time is reached. The Task Scheduler use a queue to process the tasks in parallel. Due to queuing up of Task, you may not get accurate timeouts with seconds accuracy.
