  1. Yes it becomes permanent as it is part of the ddl.
  2. Yes alter table logging will making it logging again.
  3. No there isn't a method within a single command to move an object nologging and have it be logging afterwards. It is very standard to rebuild certain objects nologging and then make them logging again. I do this nightly in my data warehouse where I rebuild bitmap index in parallel nologging and then alter them noparallel logging.

If I run:
Alter table move nologging lob ...
1) Does the "nologging" part become permanent for the table or is it just for the move.
2) Will "Alter table logging" after the move command reactivate the logging of transactions for the table.
3) Is there an option to suppress login just for the move, like append does for insert?
