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.
