How to Clone a PDB
Cloning a database used to be a difficult, if not a hectic process. Before 12c the most efficient method to create the clone required using RMAN. However even this method has quite a number of steps inlvolved. In 12c too, the effort required to clone the CDB database is almost same as before but not for PDBs.
Cloning PDB is as easy as executing three to four simple commands. As PDBs will have the actual user data in them so this will be a ground breaking feature in multiple deployments scenarios.
