SubjectO_DIRECT please; Sybase 12.5
At work I had to sit through a meeting where I heard
the boss say "If Linux makes Sybase go through the page cache on
reads, maybe we'll just have to switch to Solaris. That's
a serious performance problem."
All I could say was "I expect Linux will support O_DIRECT
soon, and Sybase will support that within a year."

Er, so did I promise too much? Andrea mentioned O_DIRECT recently
(, )
Is it supported yet in 2.4, or is this a 2.5 thing?

And what are the chances Sybase will support that flag any time
soon? I just read on news://
that Sybase ASE 12.5 was released today, and a 60 day eval is downloadable
for NT and Linux. I'm downloading now; it's a biggie.

It supports raw partitions, which is good; that might satisfy my
boss (although the administration will be a pain, and I'm not
sure whether it's really supported by Dell RAID devices).
I'd prefer O_DIRECT :-(

Hope somebody can give me encouraging news.
