OCFS2 is a shared-disk cluster file system. OCFS2 is not a general-purpose file system but can contain all Oracle data files, redo and archive log files, and control files. OCFS2 presents a consistent file system image across the servers in an Oracle cluster and eliminates the need for managing raw devices, thereby simplifying the administration of RAC.
Sybase has tested and certified that Replication Agent can successfully replicate data from an Oracle RAC database running on OCFS2.
