More or less the same as MSSQL and I suppose MySQL. I'd venture the purchase of MySQL by Oracle *finally* opened the eyes of the sacrosanct "marketing experts" who decide what gets added in each new release...
Last bit of info I have indicates they got it completely wrong: all PDBs share
the same container redo log set! Talk about contention...
One of the *biggest* advantages MSSQL has in this field is that it is possible
to optimize I/O for each PDB log set.
With 12c if it stays with a global redo log? Ah yes, of course: buy Exadata!
That's gonna work really well...

I think it is. But to me the best thing about it is the easier to handle security across PDBs and within each, as well as the data masking capabilities and being able to use PL/SQL from inside SQL without going through the whole "create this and that" rigmarole. Really useful stuff. Received on Thu Oct 18 2012 - 11:06:23 CEST
