If you refer to http://download.oracle.com/docs/cd/B19306_01/rac.102/b14197/admcon.htm it has been written that Oracle suggest that we use UDP protocol for cluster interconnect ,but UDP
is an unreliable protocol , don't it cause losing data ?
don't you think that it's not proper for clusters interconnection ?

It's a matter of performance. TCP is rather slow for interconnect traffic. If your interconnect network is so unreliable that UDP is not good enough, you have a serious problem that will probably make RAC impossible to implement.
