Ever wondered which global trace flags are active in your SQL Server environment? You can easily discover them using the following command:
DBCC TRACESTATUS (-1);
This command reveals all currently enabled global trace flags. For instance, you might encounter some common ones like:
- TF 3226: This flag is a neat trick to keep your SQL Server Error Log cleaner by suppressing messages for successful database backups.
- TF 6534: If you're working with spatial data, this flag is your friend! It enables the use of native code, which can significantly boost performance.
- TF 7745: Important for maintaining data integrity, this flag prevents Query Store data from being written to disk during a failover or shutdown.
To enable a specific trace flag, simply use the DBCC TRACEON command, replacing <Ftrace flag> with the desired flag number:
DBCC TRACEON <Ftrace flag>
For a comprehensive understanding of SQL Server trace flags and their functionalities, refer to the official Microsoft documentation.
