ASM for database data files is available in 10g, and most RAC sites use ASM, not OCFS. ACFS is available in 11gR2, and can be used for most other file types. You can run 11gR2 Clusterware and ASM under a 10Gr2 database, and thus create an ACFS file system if you want to share files in addition to Oracle data files.
