Regarding chattr and changing atime updates on Oracle database files... here's the response I got from Oracle support:

---

UPDATE:

---

According to "man chattr":
When a file with the 'A' attribute set is modified, its atime record is not modified. This avoid a certain amount of disk I/O for laptop systems.

I am not aware of a reason why this would have negative side-effects, but we cannot endorse it's use. Changing the file attributes like that has not been tested by development, so we will not be able to support it.

And here's my response:

---
