          Connnect computer(B). If you set up a tnsalias on computer(a) enabling a sqlnet connection, its a bit easier. But if you want a change on (b) you have to.... make the change on (b).
          $ sqlplus /nolog
          connect <username>@b
          ... password ...
          alter table <tablename> modify ( <column> <column change> );
          That assumes on (a) you have added a tnsalias for "b" in the tnsnames.ora file, the (SERVER = DEDICATED) line is optional. unless you want to ensure you don't get a shared server connection to b:
          B = 
            (DESCRIPTION =
              (ADDRESS = (PROTOCOL = TCP)(HOST = [<b hostname>[.myco.com]]|[or b IP address])(PORT = 1521))
              (CONNECT_DATA =
                (SERVER = DEDICATED)
                (SERVICE_NAME = XE)
