Hi!
It doesn't work from PDB, but it does work from CDB. I agree that this
is an annoyance.

Hi all,
In the little annoyances when going to CDB, the major problems I see are related to dictionary views that are partly broken. Things like:

Which will probably never been fixed. Probably not a problem in production but I've seen several homemade development frameworks failing on PDB when reading metadata. So it is not only the application and the DBA scripts that have to be tested. The whole tools covering the whole development life-cycle as well.

Hi Neil!
Multi-tenant doesn't make any sense because the resources it will
save
are much, much cheaper than the cost of the multi-tenant option.
Also,
the competitors (DB2, SQL Server, SAP Hana) are all allowing
creation of
additional databases for free. I don't see why would I need to pay
for
the same feature with Oracle?
