![]() ![]() Ideally, the BizTalkMsgBoxDb database shouldn't be holding any data. We have seen that when the BizTalkMsgBoxDb database is larger, performance problems can occur. You may experience issues with large databases or tables Therefore, blocking, and deadlocking indicate a potential problem. However, these locks or blocks don't remain for an extended time. Typically, locks and blocks occur in a BizTalk Server environment. Locking, deadlocking, or blocking may occur Therefore, you should never rebuild the BizTalk Server indexes while BizTalk Server processes data. Online indexing can't be performed in these columns. Many BizTalk Server tables contain columns that use DataType definitions. If the Scan Density value that's returned by the DBCC SHOWCONTIG statement is less than 30 percent, the BizTalk Server indexes can be rebuilt during downtime. Therefore, fragmentation typically occurs. The BizTalk Server indexes are GUID-based. You can use the DBCC SHOWCONTIG SQL Server statement to display fragmentation information for the BizTalk Server tables. Most BizTalk Server indexes are clustered (index ID: 1). If the run_value and config_value properties aren't set to a value of 1, execute the following stored procedure in SQL Server to set them to 1: EXEC sp_configure 'show advanced options', 1 ĮXEC sp_configure 'max degree of parallelism', 1 ĭetermine when you can rebuild BizTalk Server indexes To determine the max degree of parallelism setting, execute the following stored procedure against the Master database in SQL Server: EXEC sp_configure 'show advanced options', 1 ĮXEC sp_configure 'max degree of parallelism' ![]() In later SQL versions, it's also possible to specify this setting per database instead of per SQL instance. On the computer that is running SQL Server and hosting the BizTalkMsgBoxDb database, set the max degree of parallelism run_value and config_value properties to a value of 1. You must set the Max Degree of Parallelism property correctly If this setting is set to on, turn it off by executing the following stored procedures in SQL Server: EXEC sp_dboption 'BizTalkMsgBoxDB', 'auto create statistics', 'off'ĮXEC sp_dboption 'BizTalkMsgBoxDB', 'auto update statistics', 'off' You should set the current setting to off. To determine whether these settings are disabled, execute the following stored procedures in SQL Server: EXEC sp_dboption 'BizTalkMsgBoxDB', 'auto create statistics'ĮXEC sp_dboption 'BizTalkMsgBoxDB', 'auto update statistics' ![]() You must keep the auto create statistics and auto update statistics options disabled on the BizTalkMsgBoxDb database. You must disable the auto create statistics and auto update statistics options This article describes how to maintain BizTalk Server databases and how to troubleshoot BizTalk Server database issues.
