How do I get the Physical Reads

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
