12cR2 New Features

FLASHBACK PLUGGABLE DATABASE now available in #Oracle 12cR2

With the current release 12.2, flashback can be done on the PDB layer. As a prerequisite, the database must be put into local undo mode. That means that each PDB has its own undo tablespace. Some other 12.2 features like hot PDB cloning also require this, so chances are that most 12cR2 multitenant databases will be using that mode.
