Resolution:
If the customer has trouble in using the domainutility from the GUI because of x-windows, or they
prefer to use commaind line, they can always choose to use it by domainutilitycmd, which has the
syntax of:
domainutilitycmd -cmdFile &ltfile> [ -domain &ltname> ] [ -usr &ltuser> -pwd &ltpassword> ] [ -logFile &ltfilename> ] [-verbose] [-lang &ltlocale>] [-help | -? | -h]

In the above command, a command file of *.xml is required.
