All Oracle Database 12c installation options are very similar to the Oracle Database 11g installation other than the new concept of container & pluggable databases. To create the container database with pluggale databases in Oracle 12c following options can be used in the installation wizard or in DBCA.
The checkbox "Create As Container Database" has to be selected and the option "Create a Container Database with one or more PDBs" should be chosen with the number of pluggable databases and prefix of the pluggable database.
