how oracle prevent "partial write"

649748Jun 13 2010 — edited Jun 15 2010
mysql innodb use "Double Write" to prevent partial write.

But oracle doesn't have "Double Write", so what's the mechanism in oracle to prevent partial write?

We are planning to use 32k block size, and the file system level the block size is 8k. So if oracle writes 32k, but only the first blocks wrote to disk before crash, how oracle recover?
