reset-db-cluster-parameter-group

Description

Modifies the parameters of a DB cluster parameter group to the default value. To reset specific parameters submit a list of the following: ParameterName and ApplyMethod . To reset the entire DB cluster parameter group, specify the DBClusterParameterGroupName and ResetAllParameters parameters.

When resetting the entire group, dynamic parameters are updated immediately and static parameters are set to pending-reboot to take effect on the next DB instance restart or RebootDBInstance request. You must call RebootDBInstance for every DB instance in your DB cluster that you want the updated static parameter to apply to.

Synopsis

  reset-db-cluster-parameter-group
--db-cluster-parameter-group-name <value>
[--reset-all-parameters | --no-reset-all-parameters]
[--parameters <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

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

The name of the DB cluster parameter group to reset.

--reset-all-parameters | --no-reset-all-parameters (boolean)

A value that indicates whether to reset all parameters in the DB cluster parameter group to their default values. You can’t use this parameter if there is a list of parameter names specified for the Parameters parameter.

--parameters (list)

A list of parameter names in the DB cluster parameter group to reset to the default values. You can’t use this parameter if the ResetAllParameters parameter is enabled.

(structure)

This data type is used as a request parameter in the ModifyDBParameterGroup and ResetDBParameterGroup actions.

This data type is used as a response element in the DescribeEngineDefaultParameters and DescribeDBParameters actions.

ParameterName -> (string)

Specifies the name of the parameter.

ParameterValue -> (string)

Specifies the value of the parameter.

Description -> (string)

Provides a description of the parameter.

Source -> (string)

Indicates the source of the parameter value.

ApplyType -> (string)

Specifies the engine specific parameters type.

DataType -> (string)

Specifies the valid data type for the parameter.

AllowedValues -> (string)

Specifies the valid range of values for the parameter.

IsModifiable -> (boolean)

Indicates whether (true ) or not (false ) the parameter can be modified. Some parameters have security or operational implications that prevent them from being changed.

MinimumEngineVersion -> (string)

The earliest engine version to which the parameter can apply.

ApplyMethod -> (string)

Indicates when to apply parameter updates.

SupportedEngineModes -> (list)

The valid DB engine modes.

(string)

Shorthand Syntax:

ParameterName=string,ParameterValue=string,Description=string,Source=string,ApplyType=string,DataType=string,AllowedValues=string,IsModifiable=boolean,MinimumEngineVersion=string,ApplyMethod=string,SupportedEngineModes=string,string ...

JSON Syntax:

[
  {
    "ParameterName": "string",
    "ParameterValue": "string",
    "Description": "string",
    "Source": "string",
    "ApplyType": "string",

  }
  ...
]

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

Example 1: To reset all parameters to their default values

The following reset-db-cluster-parameter-group example resets all parameter values in a customer-created DB cluster parameter group to their default values.

aws rds reset-db-cluster-parameter-group \
    --db-cluster-parameter-group-name mydbclpg \
    --reset-all-parameters

Output:

{
    "DBClusterParameterGroupName": "mydbclpg"
}

For more information, see Working with DB parameter groups and DB cluster parameter groups in the Amazon Aurora User Guide.

Example 2: To reset specific parameters to their default values

The following reset-db-cluster-parameter-group example resets the parameter values for specific parameters to their default values in a customer-created DB cluster parameter group.

aws rds reset-db-cluster-parameter-group \
    --db-cluster-parameter-group-name mydbclpgy \
    --parameters "ParameterName=max_connections,ApplyMethod=immediate" \
                 "ParameterName=max_allowed_packet,ApplyMethod=immediate"

Output:

{
    "DBClusterParameterGroupName": "mydbclpg"
}

For more information, see Working with DB parameter groups and DB cluster parameter groups in the Amazon Aurora User Guide.

Output

DBClusterParameterGroupName -> (string)

The name of the DB cluster parameter group.

Constraints:

  • Must be 1 to 255 letters or numbers.

  • First character must be a letter

  • Can’t end with a hyphen or contain two consecutive hyphens

Note

This value is stored as a lowercase string.
