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).Received on Mon Jun 16 2008 - 23:12:46 CDT
