To start SQL Server with a trace flag, add the -Ttrace_flag_number option to the command line (or in setup), as shown in this example:
sqlservr -dc:\sql\data\master.dat -ec:\sql\log\errorlog -T4030
Note The -T option is case sensitive. In addition, it does not allow space between the -T and the trace_flag_number.
To start SQL Server with multiple trace flags, repeat the -T option for each trace flag, as shown in this example:
sqlservr -dc:\sql\data\master.dat -ec:\sql\log\errorlog -T4030 -T4031
