So there I was, working on a request for how to restore from a specific backup.
Since the backup was using TAG, the easy solution is:
start database nomount.
restore controlfile from autobackup
startup mount database
restore database from tag ‘TAG';
recover database / recover database until sequence
open database resetlogs
The issue with the demo is that it’s too simplistic.
What happens when a new tablespace or backup is created after the TAG backup and will restore controlfile from autobackup work?
