Not sure on this one, but I think using this on NetApp will corrupt your =
datafiles (worst case) or just cause your instance to crash at random =
times (best case).

Subject: comments on forcedirectio
I've read articles that encourages the use of forcedirectio on redo logs =
but discourages on oracle datafiles. With my limited understanding on =
the forcedirectio option, I believe it should be used on Oracle =
datafiles to eliminate double buffering. The use of forcedirectio should =
improve database performance.=20
Are there any reasons why the option should not be used on Oracle =
datafiles? Does the use of the option depends on the type of storage =
array? We have 9.2.0.4 databases on SUN StorEdge T4 and NetApp.
Thanks.
Geraldine
