set transaction use rollback segment <segment name>;

This must be the first line in your transaction, and the specified rollback segment will be in use until you end the transaction.

I have to say, except for a very few situations (like using a very large rbs for a big update), I think you should be wary of using such a statement - Oracle is usually very good at allocating the best/least used  rollback segment.

Oracle 9 does away with it all together in favour of UNDO

Bob is right about the command, but please note that you cannot give that command directly in Forms. You have to use the forms_ddl built in.  An example is given below :

DECLARE
  rbs_stmnt VARCHAR2(200);
BEGIN
  rbs_stmnt := 'set transaction use rollback segment rbs1';
  forms_ddl(rbs_stmnt);
end;

Please read the forms_ddl built in description given in forms help
