I am not able to proceed further .is there any configuration problems in any of sqlnet.ora /names.ora /etc ...

Can anyone tell me where exactly i am going wrong ...

I think the port # for a name server is 1527 or something. Try changing the port#. If that doesn't work then try. Were you getting any tns errors. If so what are they? Why would you want to have an SID with name "rman", which is a v.bad practice as there is an oracle utility called rman too.
