Filesystem device O/S Buffering

Can anyone explain how Oracle ensures that data gets written to the disk
after a commit when using filesystem devices?  With Solaris filesystems,
data can be stored in the disk cache for up to 20 seconds before being
flushed.  Does Oracle use some special O/S call to force the flush?  Or does
it bypass the O/S disk cache somehow?



I can't seem to find any white-papers or FAQ's on this and Oracle tech
support doesn't seem to want to answer the question.  Please help!
