reset_db_parameter_group

RDS.Client.reset_db_parameter_group(**kwargs)

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.

    DBParameterGroupName='string',
    ResetAllParameters=True|False,
    Parameters=[
        {
            'ParameterName': 'string',
            'ParameterValue': 'string',
            'Description': 'string',
            'Source': 'string',

        },
    ]
)

Parameters:

• DBParameterGroupName (string) –

  [REQUIRED]

  The name of the DB parameter group.

  Constraints:

  • Must match the name of an existing DBParameterGroup.

• ResetAllParameters (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

    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.

    • 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.

Examples

This example resets all parameters for the specified DB parameter group to their default values.

response = client.reset_db_parameter_group(
