Remote Cloning of Pluggable Databases
in Oracle Database 12.1.0.1

Cloning of Pluggable Database in Oracle Multitenant is a great feature and very useful. It had just a tiny flaw in Oracle Database 12.1.0.1: Remote cloning from one to another CDB fails. This will work flawless beginning with the first patch set Oracle 12.1.0.2 – but if you want to use that feature still in Oracle 12.1.0.1 you need to apply at least PSU3 or a single patch 18898403.
