helpdesk.hcl,
                Hi, in your case, I think you have to restore and recover that 
datafile , and then later offline the rbs segments and then drop the tablespace.(I 
assume that you are in archive log mode)
                Or you are in trouble.You have to use undocumented parameters to force 
open the database and drop the tablespace and rbs segments.and then recreate the whole 
database.
        Good luck
