Hi hacketta1,

Ur setup is gud. set db_file_multiblock_read_count to 16 as 89 is default. but having all the data in one datafile is bad idea.
did u segregate the index, rollback segments and temp segments into other TS?? if not its again a bad practice. need not worry abt number of segments as u have db_block_size as 8K, cos 8K is less very size.

Did i asnwer ur question?
