OK, it is now running on SLES9 with Oracle 10G.
I also sent an e-mail to suse-oracle@suse.com to subscribe.  Thank you
for the tip.


I can see two AIO running when I do a ps on SLES9:
root       350     6  0 10:06 ?        00:00:00 [aio/0]
root       351     6  0 10:06 ?        00:00:00 [aio/1]

On the aix side I can see many daemons so I was expecting more aio
daemons on linux.  is two sufficient? are there parameters to tune?

Oracle has aio set i.e. init.ora parameter DISK_ASYNC_IO is true.
