FIX: BizTalk Server 2006, BizTalk Server 2006 R2 or BizTalk Server 2009 experiences low performance when you execute an SQL query that refers to the "ActivityID" field in the bam_ActivityName_CompletedRelationships table

Consider the following scenario:

• You have a computer that is running Microsoft BizTalk Server 2006, Microsoft BizTalk Server 2006 R2 or BizTalk Server 2009.
• You execute an SQL query that refers to the ActivityID column of the bam _ActivityName_ CompletedRelationships table for some Business Activity Monitoring (BAM) data.
  
  Note The bam _ ActivityName _CompletedRelationships table is in the BAMPrimaryImport database.

In this scenario, the query execution time is very slow,

This problem occurs because there is no index on the ActivityID column in the bam_ActivityName_CompletedRelationships table.

For BizTalk Server 2006

Usage RFH3380 <serverName><DatabaseName> or RFH3380
