Oracle’s web site. It’s designed to allow you to use the same storage in
a clustered configuration. We use its predecessor OCFS for one of our old
Oracle RAC environments but RAC isn’t required as OCFS2 handles its own
clustering setup. Its also reportedly a much improved product over
OCFS(1). It uses Linux’ O_DIRECT stuff for the file sharing so the
tools you use have to be O_DIRECT aware and I think most of the newer ones
(tar, ls, cp, mv etc…) are. When we did it back on RHEL3 (2.4
kernel) we had to load the utilities Oracle had made that were (also open source).<u5:p></u5:p></span></font><u1:p></u1:p><o:p></o:p></p>
