Creating and Managing a DWS Resource Management Plan

Functions

The resource management plan is an advanced resource management feature provided by DWS. You can create a resource management plan, add multiple stages to the plan, and configure different queue resource ratios for the stages. After a plan is started, it automatically changes the resource configurations in different stages as scheduled. If you need to run services in different stages with different proportions of resources, you can create a resource management plan to automatically change resource configurations in different stages.

Notes and Constraints

• The default start time is the UTC time. The next execution time is your local time. Configure the time, date, and month. Do not set an invalid date, for example, February 30.
• Stages cannot be added to or deleted from a running resource management plan.
• Before creating a resource management plan and importing stages, you must design and create a resource pool. For details, see Creating a Resource Pool.
• You can create up to 10 resource management plans, but only one plan can be started for each cluster. Each plan can contain up to 48 stages, and must have at least two stages before it can be started.
• You cannot import or delete a running resource management plan.
