What's wrong with V$SYSSTAT, db block gets + consistent gets = logical io
(there may even be a logical IO stat, can't recall and too lazy to look) and
physical reads. Don't worry about the cache rate but track the rate of logical IO and physical IO.

Having missed the web cast ... is there as simple way to identify LIOs and PIOs in the database 'as of now'? I know Craig_at_orapub does it by setting trace and then calculating values off the trace file.

But is there a simple way to calculate without generating traces?

Thanks in advance
Raj

Moi wrong ;-) Jeeh, human after all

To summarize the webcast:
db-block-buffers do mattter. Too many LIO do matter. Too many PIO do matter. But Buffer Cache Hit ratio doesn't matter ....... End user satisfaction does matter.

I am always willing to clarify any points that I made, you just have to ask me l ....
