Hi Pavan,
not sure what exactly you expect, but Maruthi has given an important and helpful answer: you have to be aware that the SUM is not started by a command, but by using the correct URL in a browser after configuring the host agent (with STARTUP confighostagent), as stated in the SUM guide.
Your answer does not reflect any hint whether you are aware of the fact that your approach is wrong, neither if you have read the guide, nor what exactly you have tried.
Stating "I tried with couple of other options" without details is a useless statement, sorry.
Regards, Boris
