Creates a new DB parameter group.

A DB parameter group is initially created with the default parameters for the database engine used by the DB instance. To provide custom values for any of the parameters, you must modify the group after creating it using ModifyDBParameterGroup . Once you've created a DB parameter group, you need to associate it with your DB instance using ModifyDBInstance . When you associate a new DB parameter group with a running DB instance, you need to reboot the DB instance without failover for the new DB parameter group and associated settings to take effect.


After you create a DB parameter group, you should wait at least 5 minutes before creating your first DB instance that uses that DB 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 instance. This is especially important for parameters that are critical when creating the default database for a DB instance, 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 DescribeDBParameters command to verify that your DB parameter group has been created or modified.

--db-parameter-group-family <value>

[--generate-cli-skeleton <value>]


--db-parameter-group-name (string)

The name of the DB parameter group.


  • Must be 1 to 255 letters, numbers, or hyphens.
  • First character must be a letter
  • Can't end with a hyphen or contain two consecutive hyphens


This value is stored as a lowercase string.

--db-parameter-group-family (string)

The DB parameter group family name. A DB parameter group can be associated with one and only one DB parameter group family, and can be applied only to a DB instance running a database engine and engine version compatible with that DB parameter group family.

To list all of the available parameter group families, use the following command:

aws rds describe-db-engine-versions --query "DBEngineVersions[].DBParameterGroupFamily"


The output contains duplicates.

--description (string)

The description for the DB parameter group.

--tags (list)

Tags to assign to the DB parameter group.


Metadata assigned to an Amazon RDS resource consisting of a key-value pair.

Key -> (string)

A key is the required name of the tag. The string value can be from 1 to 128 Unicode characters in length and can't be prefixed with "aws:" or "rds:". The string can only contain only the set of Unicode letters, digits, white-space, '_', '.', ':', '/', '=', '+', '-', '@' (Java regex: "^([\p{L}\p{Z}\p{N}_.:/=+\-@]*)$").

Value -> (string)

A value is the optional value of the tag. The string value can be from 1 to 256 Unicode characters in length and can't be prefixed with "aws:" or "rds:". The string can only contain only the set of Unicode letters, digits, white-space, '_', '.', ':', '/', '=', '+', '-', '@' (Java regex: "^([\p{L}\p{Z}\p{N}_.:/=+\-@]*)$").

Shorthand Syntax:

Key=string,Value=string ...

JSON Syntax:

    "Key": "string",
    "Value": "string"

--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. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--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.

See 'aws help' for descriptions of global parameters.


To create a DB parameter group

The following create-db-parameter-group example creates a DB parameter group.

aws rds create-db-parameter-group \
    --db-parameter-group-name mydbparametergroup \
    --db-parameter-group-family MySQL5.6 \
    --description "My new parameter group"


    "DBParameterGroup": {
        "DBParameterGroupName": "mydbparametergroup",
        "DBParameterGroupFamily": "mysql5.6",
        "Description": "My new parameter group",
        "DBParameterGroupArn": "arn:aws:rds:us-east-1:123456789012:pg:mydbparametergroup"

For more information, see Creating a DB Parameter Group in the Amazon RDS User Guide.
