# UpdateResiliencyPolicy


Updates a resiliency policy.

**Note**  
 AWS Resilience Hub allows you to provide a value of zero for `rtoInSecs` and `rpoInSecs` of your resiliency policy. But, while assessing your application, the lowest possible assessment result is near zero. Hence, if you provide value zero for `rtoInSecs` and `rpoInSecs`, the estimated workload RTO and estimated workload RPO result will be near zero and the **Compliance status** for your application will be set to **Policy breached**.

## Errors


For information about the errors that are common to all actions, see [Common Error Types](CommonErrors.md).

 ** AccessDeniedException **   
You don't have permissions to perform the requested operation. The user or role that is making the request must have at least one IAM permissions policy attached that grants the required permissions.

This exception occurs when a conflict with a previous successful write is detected. This generally occurs when the previous write did not have time to propagate to the host serving the current request. A retry (with appropriate backoff logic) is the recommended response to this exception.    
 ** resourceId **   
The identifier of the resource that the exception applies to.  
 ** resourceType **   
The type of the resource that the exception applies to.
HTTP Status Code: 409

 ** InternalServerException **   
This exception occurs when there is an internal failure in the AWS Resilience Hub service.  
HTTP Status Code: 500

 ** ResourceNotFoundException **   
This exception occurs when the specified resource could not be found.    
 ** resourceId **   
The identifier of the resource that the exception applies to.  
 ** resourceType **   
The type of the resource that the exception applies to.
