# StartDBInstance
<a name="API_StartDBInstance"></a>

Starts an Amazon RDS DB instance that was stopped using the AWS console, the stop-db-instance AWS CLI command, or the `StopDBInstance` operation.

For more information, see [ Starting an Amazon RDS DB instance That Was Previously Stopped](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_StartInstance.html) in the *Amazon RDS User Guide.* 

**Note**  
This command doesn't apply to RDS Custom, Aurora MySQL, and Aurora PostgreSQL. For Aurora DB clusters, use `StartDBCluster` instead.

HTTP Status Code: 404

 ** InsufficientDBInstanceCapacity **   
The specified DB instance class isn't available in the specified Availability Zone.  
HTTP Status Code: 400

 ** InvalidDBClusterStateFault **
