3.1.4.13 TransactedUpdate

The WSDL definition of the TransactedUpdate operation is as follows:

 <wsdl:operation name="TransactedUpdate">
   <wsdl:input wsaw:Action="http://schemas.datacontract.org/2008/10/
     WorkflowServices/IWorkflowInstanceManagement/TransactedUpdate"
     message="tns:IWorkflowInstanceManagement_TransactedUpdate_InputMessage" />
   <wsdl:output wsaw:Action="http://schemas.datacontract.org/2008/10/
     WorkflowServices/IWorkflowInstanceManagement/TransactedUpdateResponse" 
     message="tns:IWorkflowInstanceManagement_TransactedUpdate_OutputMessage" />
 </wsdl:operation>

TransactedUpdate is an atomic operation that SHOULD update the identity of the durable program instance. The operation SHOULD be performed under the scope of a transaction flowed in from the client, if one is flowed in, using a protocol that is recognized by the client and server, such as the one specified in [MS-WSRVCAT]. A GUID MUST be passed to the operation as the value of the <instanceId> element to identify the durable program instance on which the operation is to be performed. The operation SHOULD return a SOAP fault message if one or more of the following conditions exist:

  • The value of the <instanceId> element is not in the correct format, as specified in [MS-DTYP] section 2.3.4.

  • The <instanceId> element is absent.

  • The value of the <instanceId> element does not exist in the Durable Program Instance Table on the server.

  • The server encounters an internal error while executing the TransactedUpdate operation.
