If you search for the phrase: Optimal Flexible Architecture

and then look at the 10g docs, you may notice a whole bunch of unix installation guide references.

Actually, it was originally put together by Cary Millsap long ago, and I recall seeing a post on oracle-l where he didn't agree with the mods for 10g.

It's just a recommendation, but a fairly good one as far as I'm concerned. There have been various mods proposed over the years, but personally I've found when I go into a new place if it is close to "standard" it's a heck of a lot easier. There are some things leftover from the old jbod days which can look weird, but in the end, it is a DBA configuration decision.

The $ORACLE_HOME/dbs default location could be considered to be a conflicting alternative configuration to OFA.
