<div id="body8662426"><p id="EN-US_TOPIC_0000001707254657__p204571957180">GaussDB(DWS) provides the intelligent O&M feature to help users quickly and efficiently execute O&M tasks. Intelligent O&M selects a proper time window and concurrency to complete specified tasks based on the cluster load. During O&M tasks, intelligent O&M monitors user service changes and promptly adapts task execution policies to minimize the impact on user services. Periodic tasks and one-off tasks are supported, and you can configure the time window as required.</p>

If some steps of an O&M task cannot be completed due to an abnormal cluster, the failed steps will be skipped for cost saving.</p>
