Here you can find the material related to my session at Oracle Open World 2014. I’m sorry I’m late in publishing them, but I challenge you to find spare time during Oracle Open World! It’s the busiest week of the year! (Hard Work, Hard Play)

There’s one slide describing the procedure for cloning one PDB using the standbys clause. Oracle has released a Note while I was preparing my slides (one month ago) and I wasn’t aware of it, so you may also checkout this note on MOS:
Making Use of the STANDBYS=NONE Feature with Oracle Multitenant (Doc ID 1916648.1)
UPDATE: I’ve blogged about it in a more recent post: Tales from the Demo Grounds part 2: cloning a PDB with ASM and Data Guard (no ADG)
UPDATE 2: I’ve written another blog post about these topics: Cloning a PDB with ASM and Data Guard (no ADG) without network transfer
Cheers!
