BUG #: 355191 (SHILOH_BUGS)



SYMPTOMS
Microsoft SQL Server 2000 Windows CE Edition (SQL Server CE) Subscribers may receive duplicate changes from the Publisher when a synchronization executes. This problem is a performance optimization issue because extra network traffic is sent to the SQL Server CE Subscriber device. The duplicate changes are not applied to the SQL Server CE Subscriber database so data convergence is not an issue.



RESOLUTION
A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next SQL Server service pack that contains this hotfix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:

http://support.microsoft.com/default.aspx?scid=fh;EN-US;CNTACTMS

NOTE: In special cases, charges that are ordinarily incurred for support calls may be canceled if a Microsoft Support Professional determines that a specific update will resolve your problem. The typical support costs will apply to additional support questions and issues that do not qualify for the specific update in question.

The English version of this fix should have the following file attributes or later:   Version      File name         Platform

8.00.435    Qfe355191.sql     i386 NOTE: Due to file dependencies, the most recent hotfix or feature that contains the preceding files may also contain additional files.



STATUS
Microsoft has confirmed this to be a problem in SQL Server 2000.



MORE INFORMATION
In a scenario where this problem occurs, a SQL Server CE Subscriber can synchronize with the Publisher and receive the changes expected. A subsequent synchronization can result in those same changes being downloaded to the SQL Server CE Subscriber from the Publisher. The next synchronization then shows that no changes are needed for a merge.

This problem is simply a performance optimization issue because the SQL Server CE Subscriber data is not affected by this problem. This problem can affect the overall time it takes to synchronize with the Publisher because changes are processed by the Publisher during a merge and sent to the SQL Server CE Subscriber device when no changes should be sent.
