RE: recovery from RAW partitions

Let's try this again.  What does "I was talking to a DBA today who insisted 
that performing a recovery with a RAW partition." mean?  What are you asking 
for agreement/disagreement on?

As to the performance improvement, if any, of raw devices, well, as with many 
things, it depends.

Personally, I use raw partitions for the following reasons:
 - AIO and DIO capable
 - no memory wastage caching datafile blocks in filesystem cache
 - Sys admin staff is comfortable w/ raw partitions
 - In my environment, there's no downside

Subject: recovery from RAW partitions

I was talking to a DBA today who insisted that performing a recovery with a RAW 
partition. He didn't really explain why. Does anyone agree with this? If so 
why? He also said that RAW partitions only give about a 2% performance 
improvement. If so, why would you want to use them (other than with voting 
disks and OCR in RAC).
