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.

Synopsis¶

  reset-db-parameter-group
--db-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-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)

A value that indicates 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)

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",
    "DataType": "string",
    "AllowedValues": "string",
    "IsModifiable": true|false,
    "MinimumEngineVersion": "string",
    "ApplyMethod": "immediate"|"pending-reboot",
    "SupportedEngineModes": ["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.

See ‘aws help’ for descriptions of global parameters.

Examples¶

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.
