FIX: A time-out error may occur when you use the BizTalk Adapter for Oracle Database as a receive adapter

Consider the following scenario:

• You use the Microsoft BizTalk Adapter for Oracle Database as a receive adapter.
• You use this receive adapter to poll data in the back-end Oracle database.
• You submit the result message to BizTalk Server.

In this scenario, a time-out error may occur. This error may occur if one of following conditions is true:

• A BizTalk Server routing error occurs on the computer that is running BizTalk Server.
• The computer that is running BizTalk Server is currently under heavy work load or is processing messages that are very large.

When the time-out error occurs, three event messages may be logged in the Application log. The source of these events appears as "Microsoft BizTalk Adapters for Enterprise Applications." The descriptions of these events appear as follows:

This problem occurs because the BizTalk Adapter for Oracle Database has a default time-out period of 30 seconds. If BizTalk Server does not receive the poll data before the time-out period expires, a time-out error occurs. The following known issues can cause this problem:

• The adapter does not handle the BizTalk Server routing error correctly.
• Some operations may cause BizTalk Server to take more than 30 seconds to obtain the result message. For example, when the result message for the poll is processed in a custom pipeline, the message may take longer than 30 seconds to process. Therefore, BizTalk Server does not receive the message before the time-out period expires.

Prerequisites

No prerequisites are required.

Restart information

You do not have to restart the computer after you apply this hotfix.

Registry information

You have to change the registry after you apply this hotfix.

After you apply this hotfix, you must manually register the Microsoft.Biztalk.Adapters.CoreReceiver.dll file in the global assembly cache. Then, you must create a registry entry to increase the time-out period to more than 30 seconds.

To manually register the Microsoft.Biztalk.Adapters.CoreReceiver.dll file, use one of the following methods. The method that you use depends on whether you have Microsoft Visual Studio 2005 installed on the computer.

Method 1: Visual Studio 2005 is installed

To manually register the Microsoft.Biztalk.Adapters.CoreReceiver.dll file, follow these steps:

1. Click Start, point to All Programs, point to Microsoft Visual Studio 2005, point to Visual Studio Tools, and then click Visual Studio 2005 Command Prompt.
2. At the Visual Studio command prompt, locate the following folder:
   %ProgramFiles%\Common Files\Microsoft BizTalk Adapters for Enterprise Applications\Bin
3. At the Visual Studio command prompt, run the following command:
   gacutil /i Microsoft.Biztalk.Adapters.CoreReceiver.dll

Method 2: Visual Studio 2005 is not installed

To manually register the Microsoft.Biztalk.Adapters.CoreReceiver.dll file, follow these steps:

1. Click Start, click Run, type cmd , and then click OK.
2. At the command prompt, locate the following folder:
   %WINDIR%\Microsoft.NET\Framework\v1.1.4322
3. At the command prompt, run the following command:
   gacutil /i "Drive:\Program Files\Common Files\Microsoft BizTalk Adapters for Enterprise Applications\Bin\ Microsoft.Biztalk.Adapters.CoreReceiver.dll"

Note The BizTalk Adapter for Oracle Database uses the Microsoft .NET Framework 1.1.

After you apply this hotfix, you can increase the time-out period to more than 30 seconds. To increase the time-out period, you must create a registry key to set the time-out value that you want. To do this, follow these steps:

1. Click Start, click Run, type regedit, and then click OK.
2. Locate the appropriate registry key, depending on the type of operating system that you have:
   • On a 32-bit-based server, locate the following registry subkey:
     HKEY_LOCAL_MACHINE\Software\Microsoft\BizTalkAdapters\Config\Global\Adapters
   • On a 64-bit-based server, locate the following registry subkey:
     HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\BizTalkAdapters\Config\Global\Adapters
3. Right-click the registry subkey that you located in step 2, point to New, and then click DWORD Value.
4. Type BatchWaitTime, and then press ENTER.
5. Right-click the BatchWaitTime registry entry, and then click Modify.
6. In the Edit DWORD Value dialog box, click Decimal in the Base group box.
7. In the Edit DWORD Value dialog box, type a number in the Value data box.
   
   Note The allowed range is 30,000 milliseconds to 300,000,000 milliseconds. By default, the value of this setting is 30,000 milliseconds. If this registry entry has been configured, an event message that contains the value of this registry entry is logged in the Application log.
8. Click OK.
9. Exit Registry Editor.
