Re: Create 12c or 18c database in traditional architecture

I would choose flat database, without a PDB. If you don't need pluggable databases, then having them is just a nuisance. I know that Oracle claims that the flat architecture will be desupported, but that hasn't happened yet. Too many customers with flat databases, I guess. That is approximately the same question whether you need an AC when moving to Alaska: probably not. Likelihood that you will have days with 80+ F  is pretty low in Alaska.

For the record:

I've only been there as a tourist in July, for a week, in the Denali Natl. Park. I needed long sleeves for both the temperatures and quarter-pounder mosquitoes. There also some larger animals there that you would be wise to give a wide berth.
