Good idea.
I would like to add that in case of a shutdown abort you do a startup
restrict and shutdown immediate afterwards to be sure no files are in a
fuzzy state. In case of a restore the redologs are not needed then.

A cold/offline backup means that the database is closed. But if you mean you make a backup of a no archivelog mode database that was open I must strongly request you not to encourage this ever again. I have seen too many lost databases because an open database backup was restored. It's true: you can make a backup of an open database. But when you restore it you chance is 99% it won't open. And you can't repair that. If you have another experience it's pure luck, but NEVER again say you can make a backup of an open database unless 2 conditions are met: a. the database runs in archive log mode b. the tablespace is in backup mode while it's files are being copied.

for
| an offline/cold backup - and especially if a shutdown abort is ever
issued.
