Microsoft SQL Server Code-Named "Denali" CTP3 Release Notes - TechNet Articles - United States (English) - TechNet Wiki

1. Exit the DQS client.
2. Using SQL Server Management Studio, run the following SQL statements against the DQS_MAIN database to disable DQS process concurrency:
   USE [DQS_MAIN]
   GO
   /****** Object: ServiceQueue [dbo].[ParallelExecutionRequestQueue] ******/
   ALTER QUEUE [dbo].[ParallelExecutionRequestQueue] WITH STATUS = ON , RETENTION = ON , ACTIVATION ( STATUS = ON , PROCEDURE_NAME = [internal_core].[ParallelExecutionActivator] , MAX_QUEUE_READERS = 1 , EXECUTE AS N'dbo' ), POISON_MESSAGE_HANDLING (STATUS = ON)
   USE [DQS_MAIN]
   GO
   /****** Object: ServiceQueue [dbo].[ParallelCalibrationRequestQueue] ******/
   ALTER QUEUE [dbo].[ParallelCalibrationRequestQueue] WITH STATUS = ON , RETENTION = ON , ACTIVATION ( STATUS = ON , PROCEDURE_NAME = [internal_core].[ParallelCalibrationActivator] , MAX_QUEUE_READERS = 1 , EXECUTE AS N'dbo' ), POISON_MESSAGE_HANDLING (STATUS = ON)
   USE [DQS_MAIN]
   GO
   /****** Object: ServiceQueue [dbo].[CalibrationRequestQueue] ******/
   ALTER QUEUE [dbo].[CalibrationRequestQueue] WITH STATUS = ON , RETENTION = ON , ACTIVATION ( STATUS = ON , PROCEDURE_NAME = [internal_core].[CalibrationActivator] , MAX_QUEUE_READERS = 1 , EXECUTE AS N'dbo' ), POISON_MESSAGE_HANDLING (STATUS = ON)
3. Restart the SQL Server service.
4. Start the DQS client, proceed with your task, and complete it.

Note: If you want to re-enable DQS process concurrency, run the above script again, and substitute MAX_QUEUE_READERS = 1 with MAX_QUEUE_READERS = 4 in all the three instances in the script.

• Do not use these anchors (‘^’ and ‘$’) in the definitive regular expression domain rule.
• If you must use them, use parenthesis around the whole clause. For example, if you want to return all domain values starting with B, use (^B) instead of ^B as the rule expression.
