The tripod of Oracle database as a service (DBaaS) rests on the strong legs of Oracle Multitenant as the enabling database architecture; Oracle Enterprise Manager for orchestration; and Oracle’s engineered systems, such as Oracle Exadata and Oracle SuperCluster, as the consolidation platforms. This total solution from a single vendor is unmatched. This session explores in detail various key capabilities of the multitenant architecture that deliver on the promise of DBaaS today.

The -f option is not needed. The only reason why I had to specify the -f was because I tried to create a btrfs file system earlier with just 2 drives in a mirrored and striped configuration..

Pass the -V option to determine the version of make.btrfs.
