BizTalk Health Monitor (BHM) reports Orphaned DTA Service Instances or the Monitor BizTalk Server SQL Server Agent job fails with an error message that resembles the following:

Step ID: 2
Job Name: Monitor BizTalk Server (BizTalkMgmtDb)
Step Name: Generate error string in case of any issue
Duration: 00:00:00
Sql Severity: 11
Sql Message ID: 50000
Retries Attempted: 0
Executed as user: BTSSQLAGENTUSER. 550 Orphaned DTA Service Instances in BTSSQLSERVER.BizTalkDTADb [SQLSTATE 42000] (Error 50000). The step failed.

These orphaned DTA service instances are never removed by the DTA Purge and Archive job. Therefore, the BizTalkDTADb database can become very large.


This problem was fixed in the following cumulative updates for BizTalk Server:

Note After you install this update, you must manually update the DTA Purge and Archive job definition to pass the additional parameter @fHardDeleteRunningInstances if you want to clean up running service instances that are older than @nHardDeleteDays. By default, this new parameter is set to 0. This continues the current behavior. If you require the new behavior, set this parameter to 1.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
