In Microsoft BizTalk Server 2006 R2, the DTA Purge and Archive SQL Server Agent job purges old data from the BizTalk Tracking (BizTalkDTADb) database. However, the EDIMessageContent table is not purged correctly. Every time that the DTA Purge and Archive job is run, only 100 rows are purged from the EDIMessageContent table. Therefore, after BizTalk Server has been running for some time, the EDIMessageContent table grows very large. Because of this, performance may be slow when you query the EdiMessageContent table.
This issue occurs because of a problem in the dtasp_PurgeTrackingDatabase stored procedure of the BizTalkDTADb database.
