Seema,

It is not a risky process. The proper way to do it is:

Alter tablespace {name} offline;
! host copy filename to newlocation;
Alter database rename file 'oldname' to 'newname'; alter tablespace {name} online;

• backup your database! *

if all goes well, remove the old file.

You obviously need to be able to take the tablespace offline to do this, so no queries or transactions may be running while you do this. You also need to perform a backup (at least alter database backup controlfile to trace).

Hope this helps.
