Para obtener una lista completa de las guías para desarrolladores de AWS SDK y ejemplos de código, consulte [Cómo utilizar este servicio con un AWS SDK](CHAP_Tutorials.md#sdk-general-information-section). En este tema también se incluye información sobre cómo comenzar a utilizar el SDK y detalles sobre sus versiones anteriores.

# Descubra los conceptos básicos de Amazon RDS con un AWS SDK
<a name="example_rds_Scenario_GetStartedInstances_section"></a>

En el siguiente ejemplo de código, se muestra cómo:
+ Cree un grupo de parámetros de base de datos personalizado y defina los valores de los parámetros.
+ Cree una instancia de base de datos que esté configurada para utilizar el grupo de parámetros. La instancia de base de datos también contiene una base de datos.
+ Cree una instantánea de la instancia.
+ Elimine la instancia y el grupo de parámetros.

    /*
    Before running this .NET code example, set up your development environment, including your credentials.

    This .NET example performs the following tasks:
    1.  Returns a list of the available DB engine families using the DescribeDBEngineVersionsAsync method.
    2.  Selects an engine family and creates a custom DB parameter group using the CreateDBParameterGroupAsync method.
    3.  Gets the parameter groups using the DescribeDBParameterGroupsAsync method.
    4.  Gets parameters in the group using the DescribeDBParameters method.
    5.  Parses and displays parameters in the group.
    6.  Modifies both the auto_increment_offset and auto_increment_increment parameters
        using the ModifyDBParameterGroupAsync method.
    7.  Gets and displays the updated parameters using the DescribeDBParameters method with a source of "user".
    8.  Gets a list of allowed engine versions using the DescribeDBEngineVersionsAsync method.
    9.  Displays and selects from a list of micro instance classes available for the selected engine and version.
    10. Creates an RDS DB instance that contains a MySql database and uses the parameter group
        using the CreateDBInstanceAsync method.
    11. Waits for DB instance to be ready using the DescribeDBInstancesAsync method.
    12. Prints out the connection endpoint string for the new DB instance.
    13. Creates a snapshot of the DB instance using the CreateDBSnapshotAsync method.
    14. Waits for DB snapshot to be ready using the DescribeDBSnapshots method.
    15. Deletes the DB instance using the DeleteDBInstanceAsync method.
    16. Waits for DB instance to be deleted using the DescribeDbInstances method.
    17. Deletes the parameter group using the DeleteDBParameterGroupAsync.

 *
 * For more information, see the following documentation topic:
 *
 * https://docs.aws.amazon.com/sdk-for-java/latest/developer-guide/get-started.html
 *
 * This example requires an AWS Secrets Manager secret that contains the

 *
 * https://docs.aws.amazon.com/secretsmanager/latest/userguide/integrating_how-services-use-secrets_RS.html
 *
 * This Java example performs these tasks:
 *
 * 1. Returns a list of the available DB engines.
 * 2. Selects an engine family and create a custom DB parameter group.
 * 3. Gets the parameter groups.
 * 4. Gets parameters in the group.
 * 5. Modifies the auto_increment_offset parameter.
 * 6. Gets and displays the updated parameters.
 * 7. Gets a list of allowed engine versions.
 * 8. Gets a list of micro instance classes available for the selected engine.
 * 9. Creates an RDS database instance that contains a MySql database and uses
 * the parameter group.
 * 10. Waits for the DB instance to be ready and prints out the connection
 * endpoint value.
 * 11. Creates a snapshot of the DB instance.
 * 12. Waits for an RDS DB snapshot to be ready.
 * 13. Deletes the RDS DB instance.
 * 14. Deletes the parameter group.

/**
Before running this code example, set up your development environment, including your credentials.

For more information, see the following documentation topic:

https://docs.aws.amazon.com/sdk-for-kotlin/latest/developer-guide/setup.html

This example requires an AWS Secrets Manager secret that contains the database credentials. If you do not create a
secret, this example will not work. For more details, see:

https://docs.aws.amazon.com/secretsmanager/latest/userguide/integrating_how-services-use-secrets_RS.html

This example performs the following tasks:

1. Returns a list of the available DB engines by invoking the DescribeDbEngineVersions method.
2. Selects an engine family and create a custom DB parameter group by invoking the createDBParameterGroup method.
3. Gets the parameter groups by invoking the DescribeDbParameterGroups method.
4. Gets parameters in the group by invoking the DescribeDbParameters method.
5. Modifies both the auto_increment_offset and auto_increment_increment parameters by invoking the modifyDbParameterGroup method.
6. Gets and displays the updated parameters.
7. Gets a list of allowed engine versions by invoking the describeDbEngineVersions method.
8. Gets a list of micro instance classes available for the selected engine.
9. Creates an Amazon Relational Database Service (Amazon RDS) database instance that contains a MySQL database and uses the parameter group.
10. Waits for DB instance to be ready and prints out the connection endpoint value.
11. Creates a snapshot of the DB instance.
12. Waits for the DB snapshot to be ready.
13. Deletes the DB instance.
14. Deletes the parameter group.

Para obtener una lista completa de las guías para desarrolladores de AWS SDK y ejemplos de código, consulte [Cómo utilizar este servicio con un AWS SDK](CHAP_Tutorials.md#sdk-general-information-section). En este tema también se incluye información sobre cómo comenzar a utilizar el SDK y detalles sobre sus versiones anteriores.

# Acciones de Amazon RDS con SDK de AWS
<a name="service_code_examples_actions"></a>

Los siguientes ejemplos de código muestran cómo llevar a cabo acciones individuales de Amazon RDS con los SDK de AWS. En cada ejemplo se incluye un enlace a GitHub, con instrucciones de configuración y ejecución del código. 

Estos fragmentos llaman a la API de RDS y son fragmentos de código de programas más grandes que deben ejecutarse en contexto. Puede ver las acciones en contexto en [Escenarios de Amazon RDS con SDK de AWS](service_code_examples_scenarios.md). 

 Los siguientes ejemplos incluyen solo las acciones que se utilizan con mayor frecuencia. Para obtener una lista completa, consulte la [Amazon Relational Database Service API Reference](https://docs.aws.amazon.com/AmazonRDS/latest/APIReference/Welcome.html).

# Uso de `ModifyDBInstance` con un AWS SDK o la CLI
<a name="example_rds_ModifyDBInstance_section"></a>

Los siguientes ejemplos de código muestran cómo utilizar `ModifyDBInstance`.

------
#### [ CLI ]

**AWS CLI**  
**Ejemplo 1: para modificar una instancia de base de datos**  
En el siguiente ejemplo de `modify-db-instance` se asocia un grupo de opciones y un grupo de parámetros a una instancia de base de datos de Microsoft SQL Server compatible. El parámetro `--apply-immediately` hace que los grupos de opciones y parámetros se asocien de inmediato, en lugar de esperar hasta el siguiente período de mantenimiento.  

```
aws rds modify-db-instance \
    --db-instance-identifier database-2 \
    --option-group-name test-se-2017 \
    --db-parameter-group-name test-sqlserver-se-2017 \
    --apply-immediately
```
Salida:  

```

        "DBInstanceIdentifier": "database-2",
        "DBInstanceClass": "db.r4.large",

**Ejemplo 2: asociar un grupo de seguridad VPC con una instancia de base de datos**  
El siguiente ejemplo de `modify-db-instance` asocia un grupo de seguridad de VPC específico y elimina los grupos de seguridad de base de datos de una instancia de base de datos:  

```
aws rds modify-db-instance \

aws rds reboot-db-instance \
    --db-instance-identifier test-mysql-instance
```
Salida:  

```
{
    "DBInstance": {
        "DBInstanceIdentifier": "test-mysql-instance",
        "DBInstanceClass": "db.t3.micro",
        "Engine": "mysql",
        "DBInstanceStatus": "rebooting",
        "MasterUsername": "admin",
        "Endpoint": {
            "Address": "test-mysql-instance.############.us-west-2.rds.amazonaws.com",
            "Port": 3306,
            "HostedZoneId": "Z1PVIF0EXAMPLE"
        },

    ... output omitted...

    }
}
```
