Example 7-1 shows how this is done usinga Windows command prompt. First the XIV_XCLIUSER variable is set to admin, then theXIV_XCLIPASSWORD is set to adminadmin. Then both variables are confirmed as set. Ifnecessary, change the user ID and password to suit your setup.Example 7-1 Setting environment variables in Microsoft WindowsC:\>set XIV_XCLIUSER=adminC:\>set XIV_XCLIPASSWORD=adminadminC:\>set | find "XIV"XIV_XCLIPASSWORD=adminadminXIV_XCLIUSER=adminTo make these changes permanent:1. Right-click the My Computer icon and select Properties.2. Click the Advanced tab.3. Click Environment Variables.Chapter 7. Data migration 205
