The OFA standard Is a set of configuration guidelines created to ensure fast and reliable Oracle databases that require little maintenance.
It is designed to enable the following:
i. Organize large amounts of complicated software and data on disk, to avoid device bottlenecks and poor performance
ii. Facilitate routine administrative tasks, such as software and data backup, which are often vulnerable to data corruption
iii. Facilitate switching between multiple Oracle databases
iv. Adequately manage and administer database growth
v. Help eliminate fragmentation of free space in the data dictionary, isolate other fragmentation, and minimize resource contention
