Consider the following scenario in Microsoft BizTalk Server 2006:

• You use the BizTalk Adapter for Oracle Database to connect to Oracle 8, Oracle 9i, or Oracle 10g.
• You have applied the following three hotfixes for BizTalk Server:
  934040  (http://kbalertz.com/Feedback.aspx?kbNumber=934040/ ) FIX: One of the Microsoft BizTalk Adapters for Enterprise Applications stops processing incoming messages until you restart the BizTalk Host instance
  942419  (http://kbalertz.com/Feedback.aspx?kbNumber=942419/ ) FIX: Event ID: 1723 occurs when you use Adapters for Enterprise Applications with BizTalk Server 2006 to process lots of messages
  959105   (http://kbalertz.com/Feedback.aspx?kbNumber=959105/ ) FIX: Multiple RunTimeAgent processes are created when you use the Microsoft BizTalk Adapter for Oracle database to connect to an Oracle server

In this scenario, you find that the Application log shows error messages that resemble the following.

Error 1

Error 2

Error 3

When this problem occurs, some messages may be lost.

This problem occurs because of an error in how Microsoft BizTalk Adapters for Enterprise Applications handles transmission operations.

1. Open the BizTalk installation folder. For example, open the following folder:
   
   C:\Program Files\Microsoft BizTalk Server 2006
2. Open the BTSNTSvc.exe.config configuration file that is in the folder.
3. Add the following node inside the <configuration> node.

   <system.diagnostics>
                                   <trace autoflush="true" indentsize="2">
                                                   <listeners>
                                                                   <remove name="Default"/>
                                                                   <add name="TextWriterTraceListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="C:\\AdapterLog.txt"/>
                                                   </listeners>
                                   </trace>
                                   <switches>
                                                   <add name="LOBAdapterTraces" value="3" />
                                   </switches>
                   </system.diagnostics>
   

   Note You can specify a different path for the log file in the initializeData attribute. The LOBAdapterTraces log levels under the <switches> attribute can be specified by using the following values.

   Value	Item	Description
   0	Off	Outputs no messages to Trace Listeners
   1	Error	Outputs only error messages to Trace Listeners
   2	Warning	Outputs error and warning messages to Trace Listeners
   3	Info	Outputs informational, warning and error messages to Trace Listeners
