Troubleshoot Installation Issues with the SAP adapter

  • Artykuł

Installation of the Microsoft BizTalk Adapter Pack copies the product binaries on the computer and registers the bindings for each adapter. This section discusses troubleshooting techniques to resolve installation errors.

Logging Messages for Setup Actions

The BizTalk Adapter Pack setup program performs the standard task of installing the BizTalk Adapter Pack. Additionally, the setup also performs certain custom actions such as registering the adapter bindings. You can log messages for both the standard as well as custom actions that the setup performs.

  • The BizTalk Adapter Pack setup installs the adapter specific files using an MSI. Hence, the logging for the setup is the standard MSI logging.

  • Logs for the custom actions that the setup program performs are available at %TEMP%\adaptersetup.log. If the tracing to the log file fails, the traces are also available in the event log.

Setup fails to register adapter bindings or data providers

Problem

The Microsoft BizTalk Adapter Pack setup wizard fails to register the adapter bindings or the .NET Framework Data Provider for mySAP Business Suite, but proceeds with the adapter installation.

Cause

This might result due to problems with Windows Communication Foundation (WCF) installation, Microsoft Windows Communication Foundation (WCF) Line of Business (LOB) Adapter SDK installation, or the machine.config file being corrupt. The adapter bindings are written to the machine.config file.

Resolution

You should manually register the SAP adapter binding or the Data Provider for SAP.

Register the adapter bindings or the data provider

  1. Navigate to the machine.config file on the computer. For example, on a 32-bit platform, the machine.config is available under <system drive>:\WINDOWS\Microsoft.NET\Framework\<version>\CONFIG.

    In this path, <version> is the version of the .NET Framework.

  2. Open the file using a text editor.

  3. To register the SAP adapter binding:

    1. Search for the element "system.serviceModel" and add the following under it:

      <client>  
  <endpoint binding="sapBinding" contract="IMetadataExchange" name="sap" />  
</client>

    2. Search for the element "bindingElementExtensions" under system.serviceModel\extensions.

    3. Look for the missing SAP adapter binding. Add the following section under the "bindingElementExtensions" node.

      For SAP adapter, add:

      <add name="sapAdapter" type="Microsoft.Adapters.SAP.SAPAdapterExtensionElement,Microsoft.Adapters.SAP, Version=<version>, Culture=neutral, PublicKeyToken=<public key>" />

    4. Search for the element "bindingExtensions" under system.serviceModel\extensions.

    5. Look for the missing SAP adapter binding. Add the following section under the "bindingExtensions" node.

      For SAP adapter, add:

      <add name="sapBinding" type="Microsoft.Adapters.SAP.SAPAdapterBindingSection,Microsoft.Adapters.SAP, Version=<version>, Culture=neutral, PublicKeyToken=<public key>" />

      Note

      For information about how to determine the public key, see Determining the Public Key and Version.

  4. To register the Data Provider for SAP:

    1. Search for the element "DbProviderFactories" under the "system.data" node.

    2. Look for the missing Data Provider for SAP. Add the following section under the "DbProviderFactories" node.

      For Data Provider for SAP, add:

      <add name="SAPClient Data Provider" invariant="Microsoft.Data.SAPClient" description=".NET Framework Data Provider for mySAP Business Suite" type="Microsoft.Data.SAPClient.SAPClientFactory,Microsoft.Data.SAPClient, Version=<version>, Culture=neutral, PublicKeyToken=<public key>" />

  5. Save and close the machine.config file.

Determining the Public Key and Version

Perform the following steps to determine the public key for SAP adapter or Data Provider for SAP.

  1. Navigate to the Windows directory, typically C:\WINDOWS\assembly.

  2. Right-click the DLL for which you want the public key, and then select Properties. The following table lists the name of the DLLs for SAP adapter and Data Provider for SAP.

    Adapter/Data Provider Name of the DLL
    SAP adapter Microsoft.Adapters.SAP
    Data Provider for SAP Microsoft.Data.SAPClient

  3. On the General tab, the value against the Public Key Token label specifies the public key for the DLL. Similarly, value against the Version label specifies the version number for the DLL.

  4. Copy the public key, and then click Cancel.

No valid adapters are installed error

Problem

Using the Add Adapter Service Reference Visual Studio Plug-in or the Consume Adapter Service BizTalk Project Add-in from Visual Studio on a 64-bit computer running 64-bit version of the BizTalk Adapter Pack results in the following error:

No valid adapters are installed on this machine

Cause

The SAP adapter is a WCF custom binding, which is registered under System.ServiceModel in the machine.config file. A 64-bit platform has two machine.config files, one used by the 32-bit applications and the other used by the 64-bit applications. So, when you install the 64-bit version of the BizTalk Adapter Pack, the setup wizard registers the bindings in the 64-bit version of the machine.config file. However, Visual Studio runs as a 32-bit process and hence when you launch the Consume Adapter Service Add-in from Visual Studio, the plug-in checks for the bindings in the 32-bit version of the machine.config file and fails giving an error.

Resolution

  • Install both the 32-bit and 64-bit versions of the BizTalk Adapter Pack on a 64-bit WCF LOB Adapter SDK installation.

    Important

    You must only have a 64-bit WCF LOB Adapter SDK installation. Side-by-side installation of 32-bit and 64-bit WCF LOB Adapter SDK on a single computer is not supported.

  • Add both the 32-bit and 64-bit versions of the client DLLs for the SAP adapter (such as librfc32u.dll) to the PATH variable. The 32-bit version of the DLLs must be added to C:\Windows\SysWow64 folder. The 64-bit version of the DLLs must be added to C:\Windows\System32 folder.

    Important

    If the adapter (32 or 64-bit) is running on a computer that has a 64-bit operating system, and you are using the adapter to write an application, you should mark the application to the same type (32 or 64-bit) as the adapter. Also, the version of the RFC SDK (32 or 64-bit) must be same as the version of the adapter (32 or 64-bit).

    For example, if a 32-bit adapter is running on a computer with a 64-bit operating system, the adapter client application must be marked as 32-bit.

Invalid binding error while configuring SAP adapter ports

Problem

When you try to configure a port for the adapter in BizTalk Server Administration console, you get the following error:

"Unable to create binding configuration element for editing. Check the values of the BindingType and BindingConfiguration properties.  
(Microsoft.Biztalk.Adapter.Wcf.Converters.CreateBindingException) Unable to get binding type for binding extension "sapBinding".  
Verify the binding extension is registered in machine.config."

Cause

The SAP adapter is a WCF custom binding, which is registered under System.ServiceModel in the machine.config file. A 64-bit platform has two machine.config files, one used by the 32-bit applications and the other used by the 64-bit applications. So, when you install the 64-bit version of the BizTalk Adapter Pack, the setup wizard registers the bindings in the 64-bit version of the machine.config file. However, BizTalk Server Administration console runs as a 32-bit process and hence when you configure a port for the adapter, it checks for the bindings in the 32-bit version of the machine.config file and fails giving an error.
