  **Request Syntax**
  ::

    response = client.update_environment(
        applyDuringMaintenanceWindow=True|False,
        desiredCapacity=123,
        engineVersion='string',
        environmentId='string',
        forceUpdate=True|False,
        instanceType='string',
        preferredMaintenanceWindow='string'
    )
    
  :type applyDuringMaintenanceWindow: boolean
  :param applyDuringMaintenanceWindow: 

    Indicates whether to update the runtime environment during the maintenance window. The default is false. Currently, Amazon Web Services Mainframe Modernization accepts the ``engineVersion`` parameter only if ``applyDuringMaintenanceWindow`` is true. If any parameter other than ``engineVersion`` is provided in ``UpdateEnvironmentRequest``, it will fail if ``applyDuringMaintenanceWindow`` is set to true.

    

  
  :type desiredCapacity: integer
  :param desiredCapacity: 

    The desired capacity for the runtime environment to update. The minimum possible value is 0 and the maximum is 100.

    

  
  :type engineVersion: string
  :param engineVersion: 

    The version of the runtime engine for the runtime environment.

    

  
  :type environmentId: string
  :param environmentId: **[REQUIRED]** 

    The unique identifier of the runtime environment that you want to update.

    

  
  :type forceUpdate: boolean
  :param forceUpdate: 

    Forces the updates on the environment. This option is needed if the applications in the environment are not stopped or if there are ongoing application-related activities in the environment.

     

    If you use this option, be aware that it could lead to data corruption in the applications, and that you might need to perform repair and recovery procedures for the applications.

     

    This option is not needed if the attribute being updated is ``preferredMaintenanceWindow``.

    

  
  :type instanceType: string
  :param instanceType: 

    The instance type for the runtime environment to update.

    

  
  :type preferredMaintenanceWindow: string
  :param preferredMaintenanceWindow: 

    Configures the maintenance window that you want for the runtime environment. The maintenance window must have the format ``ddd:hh24:mi-ddd:hh24:mi`` and must be less than 24 hours. The following two examples are valid maintenance windows: ``sun:23:45-mon:00:15`` or ``sat:01:00-sat:03:00``.

     

    If you do not provide a value, a random system-generated value will be assigned.
