Well, 1999 was 7 years ago, much has changed since then. The main thing is that now the reliable NFS3/TCP is mainstream instead unreliable of NFS2/UDP. Also, now the need for NFS mount parameters like noac and actimeo is well documented, probably not so in 1999. Also, I think synchronous NFS IO appeared into linux kernels somewhere in 2.4, so if you were on linux, it was impossible to satisfy Oracle's requirements then anyway..
