Create a preferences.xml file for each unique environment that you want to access or for each user that accesses the Data Validation Client on the same machine.
From the command line, run the DVOCmd CreateUserConfig command.
The command generates the preference file and stores it in the specified output directory. The name of the preference file is <user name>-preferences.xml.
Rename the preferences file to preferences.xml, and move it to the user configuration directory for the user.
If you create preference files for multiple users in the same output directory, move the renamed preference file to a unique location for each user.
