BUG #: 361560 (SHILOH_BUGS)



SYMPTOMS
Dynamic snapshot generation for a publication may experience performance problems that might cause the dynamic snapshot process to take longer than expected.



CAUSE
If the publication contains a large number of articles (say around 100), and each article has dynamic filters defined on them, the snapshot process does not optimize the underlying query (a system generated view that creates the BCP OUT file for the msmerge_contents table). Therefore, the dynamic snapshot process slows down.



RESOLUTION
To resolve this problem, obtain the latest service pack for Microsoft SQL Server 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

290211 INF: How to Obtain the Latest SQL Server 2000 Service Pack

NOTE: The following hotfix was created before the release of Microsoft SQL Server 2000 Service Pack 3.

The English version of this fix has the file attributes (or later) that are listed in the following table. The dates and times for these files are listed in coordinated universal time (UTC). When you view the file information, it is converted to local time. To find the difference between UTC and local time, use the Time Zone tab in the Date and Time tool in Control Panel.

NOTE: Because of file dependencies, the most recent hotfix or feature that contains the files may also contain additional files.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

This problem was first corrected in Microsoft SQL Server 2000 Service Pack 3.



MORE INFORMATION
With this fix a new snapshot option, UsePerArticleContentsView, has been added. The UsePerArticleContentsView option takes a value of 1 for ON and a value of 0 for OFF. When the UsePerArticleContentsView option is turned on, the system generated view will BCP OUT one article at a time and append it to the same .bcp file. By doing this, it avoids generating an un-optimized system generated view, thereby leading to faster execution of the dynamic snapshots.

You can also specify the UsePerArticleContentsView option as a profile parameter for the Snapshot Agent.
