modify-db-cluster-parameter-group

Description

Modifies the parameters of a DB cluster parameter group. To modify more than one parameter, submit a list of the following: ParameterName , ParameterValue , and ApplyMethod . A maximum of 20 parameters can be modified in a single request.

For more information on Amazon Aurora, see Aurora on Amazon RDS in the Amazon RDS User Guide.

Note

Changes to dynamic parameters are applied immediately. Changes to static parameters require a reboot without failover to the DB cluster associated with the parameter group before the change can take effect.

Warning

After you create a DB cluster parameter group, you should wait at least 5 minutes before creating your first DB cluster that uses that DB cluster parameter group as the default parameter group. This allows Amazon RDS to fully complete the create action before the parameter group is used as the default for a new DB cluster. This is especially important for parameters that are critical when creating the default database for a DB cluster, such as the character set for the default database defined by the character_set_database parameter. You can use the Parameter Groups option of the Amazon RDS console or the describe-db-cluster-parameters command to verify that your DB cluster parameter group has been created or modified.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Constraints:

  • Must be 1 to 255 letters or numbers.
