Starting an Instance

Scenarios

You can restart a stopped DB instance to begin using it again.

Billing

After a DB instance is started, the VM where the DB instance is located is billed again.

Constraints

  • If you start a primary instance, read replicas (if there are any) will also be started.
  • Only DB instances in Stopped state can be started.
  • When a stopped DB instance is started, a full backup is automatically triggered.
  • A stopped instance may fail to start due to insufficient ECS resources. If this happens, try again later or restore data from the latest backups by referring to Restoring a DB Instance from Backups.

Procedure

  1. Log in to the management console.
  2. Click in the upper left corner and select a region and a project.
  3. Click in the upper left corner of the page and choose Database > Relational Database Service.
  4. On the Instances page, locate the primary instance that you want to start and choose More > Start in the Operation column.
  5. In the displayed dialog box, click Yes.
  6. Refresh the instance list and view the status of the instance. If the status is Available, the instance is started successfully.
