Hello everyone,

I've come across an IBM whitepaper: "improving database performance
with aix concurrent io". IBM have tested this with Oracle 9i R2 and
claim performance comparable to raw-volume performance.

Has anyone in the community ever tried this with Oracle?
Does Oracle do an open of the database files using the o_cio flag? Or
should
one mount the jfs2 filesystem using the -o cio option?

Looking forward to your reactions.

Regards,
Hans de Git
