Re: Create 12c or 18c database in traditional architecture

Hey Yong,
as a consultant I see both in the field - I would say 60% non-CDB and 40% single-/multitenant-architecture on newer releases.

In general single-/multitenant-architecture works fine but of course there are also some nasty bugs (e.g. like #25054064) that were only introduced with this new architecture :-)

The advantage of (2) is possibly less buggy, less overhead (no mgmtdb on RAC for instance), and slightly easier management. But the disadvantage is that Oracle does not recommend it and that " (t)he non-CDB architecture was deprecated in Oracle Database 12c. It can be desupported and unavailable in a release after Oracle Database 19c."
