Re: what is meant by dirty buffers

Yeah, Oracle always has at least two names for the same thing. Dirty = Modified.

after which they are not dirty any more. That's how oracle makes changes to
speed up the process - everything is done in memory first, then written to
disk.

Hi,

In a book I read that DBWO writes dirty data buffers from data buffer

cache

to the data files. I would appreciate if someone could kindly clear my
confusion.

What is meant by dirty data buffers? If these are dirty (not good/healthy)
why to write to these to data files?

TIA!

Aleem
