Gurus, ORACLE 9.2.0.6 EE on Solaris Can I reduce the size of original undo tablespace (UNDO1) which has grown to 15 GB due to heavy import activity, by creating a second undo tablespace(UNDO2) and doing the following -- 1) alter system set undo_tablespace = UNDO2; 2) Drop tablespace undo1 including contents and datafile; 3) create original undo tablespace undo1 with small size 4) alter system set undo_tablespace = UNDO1; 5) drop the second undo tablespace ( UNDO2) -- would this work for 9.2.0.6 ? Thanks for your time Bala -- -- Bala Rao
