Austin, a db_file_sequential_read, is a randon read. The statistic name is based on how Oracle stored the read data block into the buffer cache not on how the IO is performed.

See http://www.lazydba.com/oracle/0__56581.html for backup to my point.

I have never seen proof that any other form of IO can equal Async IO when the test is exaimined closely for the details of how it was ran. HTH -- Mark D Powell -- Received on Fri Dec 17 2004 - 08:49:20 CST
