You can use compressed files with Oracle versions 10gR2, 11gR1, and 11gR2. Compression is supported in Veritas Storage Foundation for Oracle RAC (SFRAC) and Veritas Storage Foundation Cluster File System High Availability (SFCFSHA). In a clustered environment, such as SFRAC and SFCFSHA, Symantec recommends that you compress files on a node that has minimal load. In a Fast Failover SFCFSHA environment, Symantec recommends that you compress files on a passive node where the database is offline.
