Remarks
Trace flags are used to customize certain characteristics controlling how Microsoft® SQL Server™ operates. Trace flags remain enabled in the server until disabled by executing a DBCC TRACEOFF statement. New connections into the server do not see any trace flags until a DBCC TRACEON statement is issued. Then, the connection will see all trace flags currently enabled in the server, even those enabled by another connection.
For more information about the status of trace flags, see DBCC TRACESTATUS.
Result Sets
DBCC TRACEON returns this result set (message):
DBCC execution completed. If DBCC printed error messages, contact your system administrator.
Permissions
DBCC TRACEON permissions default to members of the sysadmin fixed server role only, and are not transferable.
Examples
This example disables hardware compression for tape drivers.
