reset-db-parameter-group

Description

Modifies the parameters of a DB parameter group to the engine/system default value. To reset specific parameters, provide a list of the following: ParameterName and ApplyMethod . To reset the entire DB parameter group, specify the DBParameterGroup name 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.

Options

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

The name of the DB parameter group.

Constraints:

  • Must match the name of an existing DBParameterGroup .

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

Specifies whether to reset all parameters in the DB parameter group to default values. By default, all parameters in the DB parameter group are reset to default values.

--parameters (list)

To reset the entire DB parameter group, specify the DBParameterGroup name and ResetAllParameters parameters. To reset specific parameters, provide a list of the following: ParameterName and ApplyMethod . A maximum of 20 parameters can be modified in a single request.

MySQL

Valid Values (for Apply method): immediate | pending-reboot

You can use the immediate value with dynamic parameters only. You can use the pending-reboot value for both dynamic and static parameters, and changes are applied when DB instance reboots.

MariaDB

Valid Values (for Apply method): immediate | pending-reboot

You can use the immediate value with dynamic parameters only. You can use the pending-reboot value for both dynamic and static parameters, and changes are applied when DB instance reboots.

Oracle

Valid Values (for Apply method): pending-reboot

(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)

The name of the parameter.

ParameterValue -> (string)

The value of the parameter.

Description -> (string)

Provides a description of the parameter.

Source -> (string)

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)

JSON Syntax:

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

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

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-parameter-group example resets all parameter values in a customer-created DB parameter group to their default values.

aws rds reset-db-parameter-group \
    --db-parameter-group-name mypg \
    --reset-all-parameters

Output:

{
    "DBParameterGroupName": "mypg"
}

For more information, see Working with DB parameter groups in the Amazon RDS User Guide and 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-parameter-group example resets the parameter values for specific parameters to their default values in a customer-created DB parameter group.

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

Output:

{
    "DBParameterGroupName": "mypg"
}

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

Output

DBParameterGroupName -> (string)

The name of the DB parameter group.
