In Microsoft BizTalk Server 2004, the BizTalk Server Software Development Kit (SDK) Samples\Admin\Database Maintenance folder contains the Purge_DTADB.sql script. You can run this script to create the dtasp_PruneTrackingdatabase() stored procedure. Then, you can use this stored procedure to clear information from the BizTalk Server Document Tracking and Activity (DTA) database.
However, when you run the dtasp_PruneTrackingdatabase() stored procedure to clean up your DTA database, you may experience the following symptom. If your DTA database is large, the dtasp_PruneTrackingdatabase() procedure may take many hours to finish the cleanup operation. For example, the dtasp_PruneTrackingdatabase() procedure might require 20 hours or more to clean up a DTA database that is larger than 10 gigabytes (GB).
This problem occurs because of the method that the dtasp_PruneTrackingdatabase() procedure uses to clear information from the DTA database.
To clear information from the database, the dtasp_PruneTrackingdatabase() procedure removes the particular row from the database table instead of removing and then re-creating the whole table. Therefore, it might take a long time for the dtasp_PruneTrackingdatabase() procedure to finish purging the DTA database.
Note While there is some default information that must be written to some tables in the DTA database, it is generally quicker for a procedure to remove and then re-create the whole table than to remove rows from the particular database table.

Hotfix installation informationThis hotfix contains a Microsoft SQL Server 2000 script that is optimized for cleaning up the existing BizTalk Server DTA database of all completed instance information. After you run this script, only information about instances that have not yet finished running remains in the DTA database. This cleanup process runs quickly when the number of incomplete instances in the tracking database is low. To run this script, follow these steps:
Important When you use the dtasp_PruneTrackingdatabase() stored procedure to clean up the BizTalk Server DTA database, you can configure the dtasp_PruneTrackingdatabase() stored procedure to clear items that are earlier than a particular date. You cannot configure the Bts_tracking_shrinkexistingdatabase.sql script to perform this same functionality. The Bts_tracking_shrinkexistingdatabase.sql script truncates the tables in the DTA to clear all completed instances from the DTA database. Incomplete instances are not removed.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
