Home -> Community -> Usenet -> c.d.o.server -> Any side-effects for using "natime" File systems for Oracle on Unix? Thanks
Hi Guys
I recently saw a performance benchmark article on Linux file system. According to this article Linux does an update on the "Last-time Read" attribute of any file it accesses to read. This article claimes that the io can be cut in half if we disable this update (very hard to believe!). I think the same behaviour exists in HP-UX 10.20 as well (has a "noatime" attribute on file systems).
We run Oracle 8.0.5 servers on dedicated HP 9000 machines, HP-UX 10.20. I wonder if I disable the "update last read time" on Oracle datafiles by "chattr +A file_name", would there be any side-effects on the Oracle behaviour?
Many thanks for any advise and suggestions.
Regards
