What to do after Archivelog Mode
OS: Oracle Linux 7.6
DB: Oracle 12.2
Question: My test DB is currently in No Archivelog mode, I know how to change it to Archivelog mode. I have following questions, any help would be appreciated. Thank you.
1 - What do I need to do after I change the DB to Archivelog mode?
2- Do I need to start the backups?
3- How do I ensure that I don't keep more than 24 hours(1 day) of archivelogs and backups.
Thanks.
