A CDB with a *single* PDB (aka “Single Tenant”) does not require the MultiTenant Option. It is implicitly in the Enterprise Edition.

From the 12c "Database Upgrade Guide" at

"The non-CDB architecture is deprecated in Oracle Database 12c, and may be desupported and unavailable in a later Oracle Database release. Oracle recommends use of the CDB architecture."

(There is also a note about features that are not ready in CDB architecture at the same location.)

I especially like Mike Dietrich's discussion at

Will that option be available for free? So far, it's much more economical to create several instances than to pay for multi-tenant option. According to list price, this option costs $10k/CPU thread, for an Intel server. For that money it is possible to get a whole lot of Intel-based hardware, which makes savings of 15% of CPU power and a few GB or memory a moot point. That statement of direction makes sense if and only if this option will be incorporated in the future releases. On the other hand, I believe that this option will be incorporated for free in the future releases because, for the reasons stated above, currently it doesn't make much sense to pay for it.
