 6.  After creating a workload and an XML input file, you are ready to submit the input file to the **dta** command-line utility for analysis. Make sure that you specify an XML output file name for the **-ox** utility argument. This creates an XML output file with a recommended configuration specified in the **Configuration** element. If you want to run Database Engine Tuning Advisor again to check another hypothetical configuration that is based on the output, you can copy and paste the **Configuration** element contents from the output file into a new or your original XML input file. For information about using an XML input file with the **dta** utility, see the section "Tune a Database by Using the dta Utility" in [Start and Use the Database Engine Tuning Advisor](../../relational-databases/performance/start-and-use-the-database-engine-tuning-advisor.md).
