Poon Chak,

There are several methods to do this. You can either:

1) export the table, drop the table, create the table definition in the new
   tablespace, and then import the data (imp ignore=y).

2) Create a new table in the new tablespace with the "CREATE TABLE x AS
   SELECT * from y" command:

   CREATE TABLE temp_name TABLESPACE new_tablespace AS SELECT * FROM real_table;

   Then drop the original table and rename the temporary table as the original:

   DROP TABLE real_table;
   RENAME temp_name TO real_table;

After #1 or #2 is done, be sure to recompile any procedures that may have been
invalidated by dropping the table.

I prefer method #1, but #2 is easier if there are no indexes, constraints, or
triggers. If there are, you must
manually recreate them.
