Error

El siguiente error surge con un esquema expuesto como un servicio en un receive location tipo WCF-Custom que usa binding Net.tcp y que se hospeda in-process a BizTalk Server.  La descripción del servicio (wsdl) esta expuesta vía http por medio de Internet Information Services.

Este error se presenta al momento de dar browse al servicio.

WebHost failed to process a request.

Sender Information: System.ServiceModel.ServiceHostingEnvironment+HostingManager/62476613

Exception: System.ServiceModel.ServiceActivationException: The service ‘/Test/TestSchema/TestSchemaService.svc’ cannot be activated due to an exception during compilation.  The exception message is: Root element is missing.. —> System.Xml.XmlException: Root element is missing.

Process Name: w3wp

Alternativa de Solución

La solución no esta muy relacionada con el error arrojado por BizTalk Server ya que se trata de un problema de permisos de usuario.

El usuario usado en el application pool que hospeda el servicio (generalmente se usa un usuario que pertenezca al grupo de BizTalk Isolated Host User) para poder ver su wsdl debe pertenecer a los siguientes grupos de BizTalk Server:

  • SSO Administrators
  • SSO Affiliate Administrators
  • BizTalk Isolated Host Users
  • BizTalk Administrators (esto porque posiblemente se requiere para los procesos net.tcp ya que el servicio esta hospedado en BizTalk y no en IIS)

Por último reiniciar el servidor.

Espero les funcione!

When we work with SSIS to get data from a source and load then into CRM Dynamics, we have some option which allow us to manage the particular CRM data type like Picklist. In this case we were working with the components from KingswaySoft to performance this particular task.

Normally we use the shape: Dynamics CRM OptionSet Mapping to map the values from source and the values we have to assign for each value, See the pictures bellow:

In the sheet general, we have to specify the input column we want to assign, the CRM entity ante the picklist field which contains the option.

 

 

In some cases, the values we are using to mapping are too large. In that case when you execute the ETL you get the next error: “Microsoft.SqlServer.Dts.Pipeline.DoesNotFitBufferException: The value is too large to fit in the column data area of the buffer”.

To solution this error: right click the OptionSet Mapping component and choose “Show Advanced Editor”. In the sheet: Input and Output Properties page select output and find the field you are mapping as CRM OptionSet field, and increase its Length property. Be sure you are writing a correct length for each field you are working with.

Manejo de tipo de datos personalizados de Oracle en BizTalk
Manejo de tipo de datos personalizados de Oracle en BizTalk avatar

Necesidad

Crear un parámetro de Oracle que recibe un parámetro tipo lista que posee más de un campo en su estructura, para que sea invocado desde BizTalk Server.

Error

Al intentar llamar el procedimiento de Oracle que recibe este parámetro personalizado desde el send port, se genera el siguiente error:

The adapter failed to transmit message going to send port “Cliente.XYZ.Proyecto.Subproyecto.ProcedimientoOracle_WCF-Custom” with URL “oracledb://127.0.0.1:1521/ORCL/Dedicated”. It will be retransmitted after the retry interval specified for this Send Port. Details:”Microsoft.ServiceModel.Channels.Common.MetadataException: The assembly required for type mapping not found.

Solución

Es necesario crear los asemblies de los tipos creados en Oracle y que corresponden a los interpretados por el WCF Lob Adapter. Para ello al momento de crear los esquemas desde la opción de Consume Adapter Service se debe crear estos assemblies espedificando: la ruta completa de la dll y el strong name key (.snk) que firmará la dll), esto se hace en las propiedades de UDT .NET Type Generation – Run Time.

  • GeneratedUserTypesAssemblyFilePath
  • GeneratedUserTypesAssemblyKeyFilePath

image

En el send port configurado para consumir el procedimiento en Oracle se debe especificar la ruta donde quedó generado la dll del tipo generado en el paso anterior.

Mona gracias por la respuesta!
