Recovery begins from the last checkpoint position that was calculated by the Database Writer before instance failure.

Recovery begins from the start of any ACTIVE redo log group or the start of the CURRENT log group if no other group is ACTIVE.

Oracle DBCA templates can store only logical structure and not database files.

New templates can only be created by modifying an existing user-created template.
