Hello, I need to know how to decide size of disk partitions for database and application in PROD instance of Oracle EBS R12 keeping in mind 5 year time frame. We want to have 3 members in redo logs, 3 sets of Control file all to be kept at on different disk . We have around 1 TB of disk space (300GBx11 disks). Planing to have DEV,TEST and PROD instance. Thanks in advance.
