Changing Specifications of an Instance

Scenarios

This section describes how to change your instance specifications to suit your service requirements.

Precautions

• Instances can be scaled up or down by changing their specifications.
• If one instance has multiple nodes, the change will be performed on the nodes one by one. It takes about 5 to 10 minutes for each node, and the total time required depends on the number of the nodes.
• For a node whose specifications are being changed, its computing tasks are handed over to other nodes. Change specifications of nodes during off-peak hours to prevent the instance from overload.
• To view vCPUs and nodes on the Instances page, contact customer service.
• If you forcibly change the class of an abnormal node in a DB instance, services may be interrupted.
  

  To forcibly change the class of an abnormal node, submit a service ticket by choosing Service Tickets > Create Service Ticket in the upper right corner of the management console.
