824684 Description of the standard terminology that is used to describe Microsoft software updates
Beginning with SQL Server 2000 hotfix build 8.00.798, performance enhancements were made to the Merge Agent. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
817464 FIX: Using Sp_executesql in Merge Agent operations
A new stored procedure that is named sp_MSenumchanges_direct was introduced to improve Merge Agent performance. Beginning with the 8.00.0798 hotfix, the sp_MSenumchanges procedure calls the sp_MSenumchanges_direct procedure if the following conditions are true:
  1. The user has select permissions on a table.
  2. No vertical filters are present in an article in any publication.
  3. The table has no computed or timestamp columns.
  4. The number of generations is not so high that the value of the @genlist parameter for the sp_MSenumchanges procedure would be more than 2,000 characters.
Before the 8.00.0798 hotfix, if one or more of these conditions was not true, the sp_MSenumchanges procedure called the sp_MSenumchanges_pal procedure.
The problem was that in condition 2, the Merge Agent did not check any publication except for the current publication. Also, the Merge Agent did not verify that condition 4 was true. This behavior caused the problem that is described in the "Symptoms" section. This hotfix makes the Merge Agent verify that all the four conditions are true.
