Murali, the answer is: generally speaking, you cannot have datafiles on NFS mounted filesystems. There are examples to the contrary (NetApp) but they're highly dependent upon the particular implementation. For the details, contact your friendly neighborhood oracle representative .You can, however, have read-only tablespace on NFS server. To do that, you do the following:
1) Copy read-only tablespace from a local filesystem to the NFS mounted

   one.

2) Check protection and make sure oracle can read it.
3) alter database rename file --> NFS mounted one.
4) Verify from V$DATAFILE that your datafile indeed is what it should

   be.
5) Remove the original file.

The very same procedure applies when creating a read-only tablespace on a CD.
