Does anyone have a reference or can confirm that the scope default in 12c (12.1.0.2) has changed from "memory" to "both". I have searched in the docs and OTN, but did not find any clues.
For instance: alter system set DB_CREATE_FILE_DEST='/u02/oradata';
Without specifying scope= I think the default in 11g was memory. In 12c however the change is permanent, updating the spfile.
Thanks!
