Kellyn Pot’Vin is a senior technical consultant and Oracle ACE Director who has authored books and leads various database technology groups. Oracle Multitenant was released in 2013 and allows databases called pluggable databases (PDBs) to be contained within a single container database (CDB), sharing resources. PDBs can be easily migrated, cloned, and provisioned. Monitoring and administration of CDBs and PDBs uses new database views with the CON_ID identifier to distinguish containers and pluggables.
