How do I get the Physical Reads

[JayK]

Hi all,

From the Report.txt that I analysed, I found that the Physical Reads
is 350215. I understand that this value denotes the number of
I/O requests given by Oracle to the OS to obtain the Data Blocks that
it requires. This is infact a Buffer Cache Miss in that case.

I would like to know how I can find out the actual Disk I/O that
has occured for READ from Oracle. Wouldn't it be the same as the
value indicated by Physical Reads in Report.txt , if the
File System Block Size is the same as the DB Block Size.

Best Regards
Jai
