DB version: 11.2.0.4
OS : Oracle Linux 6.9
I have recently built a standalone DB which generates rougly 20GB of archives daily. It uses Linux ext4 filesystem .Its been only 4 days in production.
My shop doesn't use Flash Recovery Area. Everyday , at 4PM, I am using RMAN to backup + Delete the archive logs now.
How should I size the Archive log destination ? Any rule of thumbs?
