List of all global trace flags that are enabled

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.
