Guys,

Querying my v$session_wait shows 10 rows each DB FILE SEQUENTIAL READ and DB FILE SCATTERED READ.

manuals explain it all b'coz of I/O.

there are 33 tables and 110 indexes in the same USERS tablespace with only one datafile USERS01.DAT of size 12GB.

it's physically laid out in D:\oracle\data. but the hard disk capacity is 100GB with 8 disk heads and RAID5.

will not moving the tables and indexes to seperate tablespace reduce I/O traffic ? my manager here says that since it is configured with RAID5 and 8 disk heads , it's not a problem.

is it so ? is he right ?
plz. clarify me. i need to explain him.
it's urgent.he is sitting on my head.

TIA.
