RE: About parallel server

Rachel, OPS or in 9i RAC (Hate name changes confuses everyone) raw devices are a requirement of the OS not Oracle. So whether you are using 7, 8, 8i, 9i you can use filesystems for OPS (RAC) if the OS supports multiple concurrent mounts on the same filesystem from multiple nodes. This is the case in OpenVMS and Compaq TRU64 v5.1 . If you use other OS's then the only way to share files is through raw devices. Now Veritas has their Cluster Files System(CFS) that allows multiple file systems to be mounted concurrently by multiple nodes. There is certification being conducted by Veritas and Oracle to support OPS in this configuration. There is more information about Veritas Cluster softerware at there site
http://www.veritas.com/us/aboutus/pressroom/2001/01-05-15 -2.html . There is also some other information on VOS (Veritas, Oracle, Sun) at http://www.vosInitiative.com/ .
