Re: 12G Desupport for Raw Devices

To quote the notice: "This means customers can no longer keep their
datafiles, OCR or Voting disks on raw devices in Oracle 12g."
What this means that the Oracle database will not support any file on
a raw device *directly*.  There will have to be a layer between the
raw device and the database (ASM, filesystem, etc).

I think this is a good, forward looking desupport notice.  Given the
pace that I have seen the significant number of customers adopt new
releases for existing production systems, it will be probably be 8
years before 12G is widely common.  I base that number on the fact
that 10g came out in 2004, and many large shops are just upgrading to
10gR2 in 2008, 4 years later.  Since 11g was released second half of
2007, add 4 years for 11gR2 (or whatever R release) to be main stream
and another 4 years for 12gR? to be main stream.  By my estimate we re
talking 2015+/- time frame.  Now obviously green field installs will
follow a faster adoption rate, but that is also the case today.
